2016 Toyota Prius Press Kit



Toyota has released a new Prius in Australia that features an engaging drive and dramatic new styling as well as the biggest improvement in fuel economy between the hybrid icon's four generations.

New Prius is the first car to benefit from the Toyota New Global Architecture philosophy that delivers cutting-edge dimensions in terms of its platform, design, powertrain and technology.

Toyota Australia's executive director sales and marketing Tony Cramb said the new Prius is a genuine breakthrough car that defines modern motoring.

"Toyota has changed the entire focus and perspective of Prius by evoking a more emotional response with a car that is fun to see, touch and drive," Mr Cramb said.

"New Prius is a mainstream car that advances its driving dynamics and driveway appeal while also delivering substantially improved innovation and efficiency."

The new Prius platform results in improved body control with a more rigid body structure and lower centre of gravity.

A redesigned front suspension and a new double-wishbone set-up at the rear improve road-holding, stability, handling and comfort.

Futuristic and stylish design cues create a high visual impact, resulting in a sleeker, better proportioned design that conveys a strong character and builds on the image-making quality of Prius.

A low-swooping bonnet, dynamic beltline, instantly recognisable triangular profile and a rear spoiler contribute to one of the world's best co-efficient of drag values: just 0.24.

The cabin offers impressive flair and simple ingenuity with a wrap-around instrument panel, a tablet-like seven-inch touch screen and quality details including soft-touch materials and striking white inserts that contrast with the black upholstery.

Every aspect of the hybrid system is even more efficient: the 1.8-litre petrol engine uses less fuel; the electric motors are smaller, lighter and more efficient; mechanical losses in the transmission are reduced; the power control unit is improved; and the hybrid battery is lighter and smaller.

As a result, new Prius has been certified for Australia with combined cycle fuel economy of just 3.4 litres/100km** - an impressive gain of 0.5 litres or 12.8 per cent.

Efficiency is only half the story as Toyota's engineers have markedly improved the hybrid driving experience, making it even more responsive, quieter under acceleration and more intuitive.

Improvements throughout the car have ensured overall performance is maintained with the adoption of a more efficient 90kW combined system output. Under partial load, which means in day-to-day driving, the driver will notice that the car is much more responsive.

Engineers have improved the eco, normal and power driving modes. To encourage greater use of the eco mode, its operation is more like the previous normal mode while power mode gains a learning function that adjusts acceleration settings and engine braking to match the driver's style.

Prius fulfills its role as high-tech ambassador with advances that provide more comprehensive information, improve safety and add to convenience.

Safety systems now standard across the range involve four technologies: pre-collision system, active cruise control, lane departure alert and auto high beam. Prius i-Tech gains blind-spot monitor* and rear cross-traffic alert that warn drivers of hazards they cannot see from the wheel.

The way information is communicated to the driver has also been enhanced, with a larger full-colour head-up display and the use of two 4.2-inch multi-information displays in the instrument panel.

An innovative air-conditioning system detects if there is a front passenger; if not, it will focus its energy on the driver alone, which can help improve fuel economy.

Smaller and lighter hybrid system components have enabled the nickel-metal hydride battery to be relocated under the rear seat, expanding luggage space to 457 litres (502 litres in i-Tech).

Every Prius is fitted with seven airbags, reversing camera, vehicle stability and traction control, anti-skid brakes, emergency brake signal, hill-start assist and smart entry and start.

The standard Prius is fitted with 15-inch alloy wheels with stylish new aerodynamic covers to promote fuel efficiency. In addition to the four new safety technologies and colour head-up display, it also gains auto-levelling bi-LED headlamps, LED daytime running lamps, 10-speaker JBL audio system, Toyota Link# connected mobility, three-spoke leather-accented steering wheel, premium door trim and a wireless phone charger##. These added features more than account for a $2,500 price increase to $34,990^.

Prius i-Tech, in addition to new safety technology, is fitted with stylish 17-inch alloy wheels with resin inserts that reduce weight. Its features also include satellite navigation and leather-accented seats with eight-way power adjustment for the driver's seat and front-seat heaters. The i-Tech price is $1,000 lower at $42,990^.

Prius is covered by capped-price servicing, Toyota Service Advantage^^, at a maximum of $140 per service.

Since the first Prius was released in Japan in late 1997, Toyota has sold more than 8.6 million hybrid vehicles around the world. Sales of Prius alone have exceeded 3.6 million vehicles, including almost 20,000 in Australia.

Fourth-generation Toyota Prius is offered in two grades, Prius and Prius i-Tech, with standard specification incorporating a comprehensive array of convenience, safety and tech features.

Key features previously reserved for the premium Prius i-Tech are now available across both grades, with enhanced functionality integrated in the process.

Prius has a comprehensive active safety package including Pre-Collision Safety System (PCS) which includes Lane Departure Alert (LDA) with steering input, Automatic High Beam (AHB) and All-Speed Active Cruise Control (ACC).

Previously exclusive to i-Tech grade, PCS is now standard on both Prius models, as are upgraded Bi-beam LED headlamps with LED daytime running lamps.

The upgraded All-Speed ACC system now operates across the vehicle's full speed range, down to a complete stop; the previous generation's dynamic radar operated at higher speeds and featured on Prius i-Tech only.

The specification shift continues with previous generation i-Tech features like leather-accented steering wheel, electro-chromatic rear view mirror and premium door trim now fitted to both Prius variants.

Prius standard specification also includes reversing camera, now with Back Guide Monitor (BGM) guidance lines; alloy wheels with aero-optimised covers; Smart Entry and Smart Start; front fog lamps; daytime running lamps; illuminated entry; steering wheel controls, audio, phone, ACC and LDA; power-adjusted driver's seat lumbar support; colour Head-Up Display (HUD); and 10-speaker JBL audio (up from eight speakers).

All infotainment functions are controlled via a seven-inch touchscreen, including the smartphone-compatible Toyota Link* multimedia system, complete with Qi wireless phone charging capability#.

New Prius' active and passive safety package features Vehicle Stability Control (VSC), ABS brakes, an emergency brake signal function, a seatbelt reminder system that now covers rear seat positions as well as the driver and front passenger, plus seven SRS airbags, including a driver's knee airbag.

Toyota executive director sales and marketing Tony Cramb said the Prius specification upgrade underpins an even more compelling combination of leading-edge technology and driver appeal.

"The new Prius matches seamless hybrid efficiency with exceptional comfort and premium features not often found in this price segment," Mr Cramb said.

"Prius i-Tech dials up the level of sophistication and sharpens the value equation even further," he said.

Prius i-Tech's additional specification includes satellite navigation^, Blind Spot Monitor (BSM) and Rear Cross Traffic Alert (RCTA), 17-inch alloy wheels (with lightweight resin inserts), tyre repair kit (in lieu of a space-saver spare wheel), increased cargo capacity, and leather-accented seats with heating for front seat passengers and eight-way power adjustment for the driver.

The new Prius adds a fun-to-drive character while evolving the best aspects of the car's ecological heritage, according to the global chief engineer Kouji Toyoshima.

"From a social perspective, we knew it was important to build on the role of Prius as an eco-leader," Mr Toyoshima said.

"At the same time, we wanted to create a more emotional response with a design that is inspiring, passionate ... perhaps even sexy."

Mr Toyoshima said he felt immense pressure to live up to the reputation of Prius for delivering better fuel economy and emissions with each new generation.

"Like world record-holder Usain Bolt, it's hard to find another one-tenth of a second or, in our case, one tenth of a litre. Success comes by challenging everything you do and by striving continuously to make even the smallest improvements, because they all add up.

"Take the petrol engine for example. Outwardly, it seems it hasn't changed, with the same capacity and basic design, but in fact we have taken its performance to a much a higher level - more complete combustion, less friction and better heat management.

"With this level of scrutiny, we have in fact made it the most thermally efficient in the world. Simply put, you get more power from every drop of fuel."

Mr Toyoshima said other major elements also received the same close attention - transmission, electric motors and hybrid battery.

"We reduced weight everywhere; it is as though they have all been put on a diet. We have managed to make things smaller as well, which let us improve the packaging, saving space and helping lower the car's centre of gravity."

Mr Toyoshima said the futuristic design for the new Prius was aimed at delivering excellent aerodynamics as well as great looks. With the youngest design team in the company's history, he said it was no surprise they had a natural inclination to produce a car with a more engaging, sportier image.

For the interior design, Mr Toyoshima cited the Japanese philosophy known as "omotenashi" (literally "hospitality"), giving the Prius a welcoming ambience.

"Some of the cues are meant to relax, others to excite. Owners and their passengers are able to travel great distances in this car - and their experience needs to be exceptional."

Mr Toyoshima, who injured his tailbone in a fall many years ago, made it his personal quest to ensure the Prius featured comfortable seats - particularly with a supportive structure and padding that helped keep occupants alert during long journeys.

"We assessed many seat structures - and I relied on my tailbone as an excellent barometer for determining the best seat angle or cushion shape. So, yes, these important decisions were made literally by the seat of my pants!"

Fourth-generation Prius is the first vehicle to be produced on the ground-breaking Toyota New Global Architecture (TNGA) platform.

TNGA encompasses major reforms to the manufacturing process and vehicle design, taking into account engine and driveline production as well as platform construction.

New design and manufacturing techniques plus greater use of ultra-high strength steels (up to 980 MPa tensile strength) and aluminium have increased torsional rigidity while meeting weight targets to save fuel and optimise handling.

TNGA is designed to deliver optimum dynamic performance, enhanced driver engagement, lower noise levels, improved safety and even greater efficiency.

Toyota has confirmed TNGA will underpin at least 50 per cent of all its vehicles within five years, and says the flexibility of the platform will also improve production efficiency and reduce manufacturing costs.

Toyota Australia executive director sales and marketing Tony Cramb said cars built under TGNA are intended to be fun to drive and inspiring to own.

"Along with chassis and suspension improvements, TNGA allows for the development of exciting new, low-stance designs," Mr Cramb said.

"Combined with even better dynamics and improved safety, this platform is a significant marker for the future of the Toyota brand," he said.

Lower centre of gravity for better driving
The new Prius' centre of gravity is 24mm lower than the outgoing model, allowing the driver's hip point to be lowered to 275mm and contributing to an improved driving position.

TNGA engineers undertook a multifaceted approach to lowering the centre of gravity, which also improves braking, cornering and stability.

New Prius sits on a specific TNGA derivative, called GA-C platform, and all areas of the vehicle were evaluated. Wherever possible, component weight was reduced, positioned lower in the vehicle, or both.

For example, the driver's hip point is lower, the redesigned powertrain allows for a lower bonnet line, and the new space-efficient rear suspension contributes to lowering the cargo floor.

The relocation of the new HV battery from the luggage area to under the rear seat is the largest single contributing factor to the lower centre of gravity.

High-rigidity body makes for better ride, handling and comfort
Special attention was paid to reinforcing key connections within the Prius body structure to increase rigidity and improve impact protection.

The result is a 60 per cent improvement in body torsional rigidity, while the weight of the body shell is reduced.

Key areas of focus include strengthening the joints between the lower part of the new, larger-section centre-pillar and both the inner floor cross-member and inner rocker panel.

Leading-edge techniques applied include three-way reinforcement, a new continuous flange structure and use of structural adhesive.

Greater use of high-strength steels has also allowed Toyota's body engineers to reduce the material gauge (thickness) in key areas such the B-pillar, rocker panels and roof rails, reducing weight of the body in white by 25 per cent.

In another Toyota first, the strength benefits of these high-tensile steel alloys are maximised through the use of Toyota's patented laser screw welding process to join critical body elements.

The new Prius also benefits from the use of structural body adhesive to bond areas of the lower door pillars and rear door opening, and is used extensively throughout the underbody to help minimise vibration, contributing to high-quality ride comfort.

Box-section construction is used for optimum rigidity of the cowl, door openings, rear body frame and back-door aperture, to increase strength and rigidity.

Reinforcements have been adopted between the rear side members and rear inner floor cross-member, and new support sections for the wheel housing inner panel have been added.

The new platform has also resulted in a turning radius of 5.1 metres for Prius and 5.4 metres for Prius i-Tech.

The new Prius offers improved steering, handling response, stability and ride comfort due to its combination of a highly rigid body, redesigned MacPherson-strut front suspension and an all-new double-wishbone rear suspension.

Parallel improvements to the electronically controlled brakes, electric power-assisted steering system and the addition of new lightweight alloy wheels mean Prius has fresh underpinnings throughout.

Improved front suspension provides better steering and certainty
Front suspension hardware, geometry and calibration have all been revised on the fourth generation Prius, with all-new low-friction damper struts.

The new struts feature a piston valve able to generate damping force at ultra-low velocities, also providing improved body control and optimum damping characteristics at higher damper velocities to reduce impact harshness on uneven surfaces.

The rate and pre-load of the coil springs have been recalibrated to help reduce impact harshness, and the anti-roll bar is ball-joint mounted to minimise uncontrolled body roll.

The new anti-roll set-up also features fluorine-resin coating on sliding parts of the mount bushings to minimise friction.

Double-wishbone rear suspension creates new handling dynamics
Toyota has developed all-new double-wishbone rear suspension for Prius to provide new levels of handling stability and ride comfort, including a substantial improvement in impact shock damping.

New body design features maximise the rigidity of the rear-suspension mounting points, ensuring optimum suspension performance on all road surfaces.

The double-wishbone layout offers numerous advantages over the torsion-beam system it supersedes, including significantly greater flexibility in fine-tuning suspension calibration.

The new suspension design builds on the foundation of the vehicle's increased torsional rigidity (+60 per cent) and strengthened suspension mounting points.

Key features of the suspension hardware and geometry include wide-mounted, forward-inclined damping struts and compact coil springs, reducing suspension friction for improved ride and liberating space to allow a lower and wider luggage area floor.

Special aero under-covers smooth air flow around the new suspension and optimise under-floor aerodynamic performance.

The new forward-tilted damping struts and a specifically tuned tyre-movement curve combine to reduce longitudinal low-frequency vibrations and further suppress road shock.

Suspension-arm rigidity and geometry have been optimised to control toe change during suspension travel to achieve supple yet responsive handling and confidence-inspiring stability.

Special attention was paid to reducing impact harshness through the suspension geometry and individual tuning of the suspension bushings, with rubber bushings replacing ball joints in some key areas to allow for further fine adjustment and reduce high-frequency vibrations.

There are multiple bushings per side in the new double-wishbone suspension, compared with one in the previous torsion-beam system.

The trailing-arm mount is positioned relatively high to optimise suspension travel, with shock-absorber and trailing bush mounting angles set to reduce harshness, road shock and stuttering.

The anti-roll bar mounting system and calibration have been tuned to ensure high levels of roll rigidity without compromising ride comfort.

New electric power-assisted steering gives greater feel
Toyota has redesigned and recalibrated the Prius' electric power-assisted rack and pinion steering (EPS), substantially enhancing each phase of its operation.

Steering feel, effectiveness and feedback have all been improved, and a new, quicker steering-gear ratio has been adopted to provide a sportier response.

The steering hardware and control software changes build on the Prius' new platform, lower centre of gravity (by 24mm) and revised front suspension to improve controllability and reduce the vehicle's turning radius.

Engineers have adopted a new steering rack ratio of 13.2:1 for Prius and 13.4:1 for Prius i-Tech compared with 14.6:1 for the superseded model.

A new, high-rigidity intermediate steering shaft improves steering effectiveness, while increased column rigidity, both laterally and vertically, delivers greater feedback from the road surface.

A new brushless electric motor provides increased assistance when required, even if the petrol engine is shut down to save fuel.

Steering on-centre feel has also been improved by adopting a worm-shaft elastic support and new control logic for the EPS.

The EPS logic has reduced the 'no assist' area when the steering is at or near centre, to increase controllability in straight-line driving.

A new feature, EPS variable damping control, has been adopted for a more progressive build-up of assistance as steering is applied as well as uniform feel during steering and return phases.

New wheels and tyres help economy and handling
Toyota has developed two new lightweight alloy wheels to complement the new Prius' suspension and further improve dynamic performance.

Increased rigidity in both designs influences tyre resonance and reduces road noise.

The new 15-inch alloy wheel is 30 per cent more rigid and 0.5 inches wider at 6.5 inches to optimise grip with the Prius' newly developed low rolling resistance tyres.

Complete with aerodynamic cover, the new, wider rim is lighter than the previous 6.0-inch full aluminium wheel.

The 17-inch alloy wheel incorporates lightweight, aerodynamically-optimised resin inserts, shaving 0.7kg per wheel in unsprung weight for improved dynamics.

Electronically controlled brakes give greater feel and certainty
Prius has a state-of-the-art electronically controlled brake system (ECBS) to balance retardation needs between regenerative and friction braking.

The ECBS also cooperates with the vehicle's electronic active safety technology, including anti-lock brake (ABS) and vehicle stability control.

Regenerative braking uses the electric drive motor as a generator, converting kinetic energy to electric energy which can be stored in the HV battery to assist acceleration later.

The new Prius friction-brake system includes floating-type aluminium front brake callipers with lightweight resin pistons acting on ventilated 255 x 25mm rotors.

The rear discs are solid 259 x 9mm rotors with aluminium rear callipers and an integrated parking brake.

Brake feel has been improved by adopting a newly developed active brake booster and new pedal ratio.

Ease of driving has also been improved with an extension on the side of the brake pedal to allow for smooth movement from the accelerator pedal.

The new Prius introduces the next generation of Toyota's signature hybrid powertrain that delivers a fuel economy gain of 12.8 per cent while being even easier and more intuitive to drive.

The system uses just 3.4 litres/100km* on the combined cycle, compared with 3.9 litres/100km in the previous generation - the largest percentage fuel-economy gain between Prius generations.

Toyota's latest Hybrid Synergy Drive package is lighter and more compact, reflecting significant advances in battery, electric motor and petrol engine technologies.

The result is improved driveability, emissions performance and fuel economy.

A stand-out feature is the thermal efficiency of the petrol engine, which has been increased to more than 40 per cent - a world's best for a mass-produced petrol unit.

The new hybrid battery offers higher energy density, enabling it to maintain its total power while being 10 per cent smaller. It also charges more quickly because it can absorb 28 per cent more energy in the same amount of time.

The electric motors are smaller and provide a better power-to-weight ratio.

Improved petrol engine

The new Prius retains the proven 1.8-litre VVT-i Atkinson cycle petrol engine; however, it has been completely re-engineered to deliver significantly better fuel economy. The gas flow, combustion, cooling and knock control have all been improved and much more effective use is made of exhaust gas recirculation.

Toyota has developed a heat recovery system that uses spent exhaust gas to speed the warming up of engine coolant. This saves fuel by allowing the hybrid system to stop the engine earlier and more often when it is not needed to power the vehicle.

Engine friction, parasitic losses, noise and vibration have all been reduced. Measures include the use of thin-section, resin-coated connecting rod bearings and a low-friction camshaft chain. Friction created by the piston skirts, rotating parts and oil pump has been reduced and a new electric water pump has helped reduce parasitic losses.

Conical "beehive" springs have been adopted to reduce the valvetrain load. The entire engine underwent computer-aided engineering analysis to achieve optimum rigidity and to reduce noise and vibration.

The intake and exhaust systems came under particular scrutiny, resulting in an engine that enjoys better breathing, air filtration, packaging efficiency, reliability and quietness. The air filter has been made smaller and its height has been reduced, which helped the designers bring down the line of the bonnet. The new intake system has a resonator that creates less noise at noticeable frequencies and the intake duct is made of a porous material that suppresses resonance.

A fresh-air inlet duct has been added to make sure ample air volume is obtained at freeway speeds and a clever air/fluid separating structure has been added to keep water and snow from mixing with the intake air. Should the fresh air duct fill with water or snow, a secondary inlet serves as the air intake.

A thinner main muffler secures optimum performance and noise reduction, while also improving the underbody aerodynamics and avoiding any intrusion on the available luggage space.

Engine cooling has been improved with a new cooling module structure and attachment, and a redesign that accommodates a lower bonnet line and helps reduce the car's centre of gravity. The engine block has V-shaped drilled paths that reduce losses in water jacket pressure.

While engine cooling helps improve anti-knock performance, it can lead to an increase in cooling heat loss. To help counter this, Toyota engineers have developed a new water jacket spacer to control temperature on the cylinder surface. This keeps engine oil warmer with lower viscosity and reduces the temperature fluctuation. This helps reduce friction and allows more engine torque to be generated. At the top end of the temperature scale, it reduces temperatures in the combustion chamber.

The engine's maximum output of 72kW is delivered at 5,200rpm with peak torque of 142Nm at 3,600rpm.

World's-best thermal efficiency
Thermal efficiency is a measurement of how well an engine converts the energy available in its fuel into useable energy to power the vehicle.

The new Prius' engine has a maximum 40 per cent thermal efficiency, the highest level in the world for a mass-produced petrol engine. This surpasses the 37 per cent level of the 1.5-litre unit in the first Prius and the 38.5 per cent level of the 1.8-litre engine in the third-generation model.

This has been achieved through the adoption of a large-volume exhaust gas recirculation system, improvements in combustion efficiency and innovative ways of managing heat and reducing friction.

Improved exhaust gas recirculation
The exhaust gas recirculation system in the new Prius has an EGR cooler which lowers the temperature of the gas being circulated, thereby reducing the temperature of the intake mixture and suppressing engine knock. This allows ignition timing to be advanced, which contributes to better thermal efficiency. Cooling loss has been reduced by eight per cent as a consequence.

Multi-shaft transaxle - a hybrid first
The new Prius has a redesigned transaxle that offers more efficient performance and packaging and reduced weight. Its smaller dimensions, notably a 59mm decrease in length, have allowed the auxiliary battery to be relocated to the engine compartment.

The transaxle houses four components: two electric motor-generators (MG1 and MG2), a single planetary gear and a reduction gear to the final drive. MG1 serves primarily as a generator, converting any surplus power from the petrol engine into electricity, which can be stored in the hybrid battery. It also serves as the engine's starter motor. MG2 is the electric drive motor, which also acts as a generator when the car is in regenerative braking mode. It drives the car from start-up, at low speed and in EV (electric vehicle) mode and is the sole propulsion method when the vehicle is in reverse.

Improved hybrid software
Updates to the hybrid system software allow the new Prius to draw more on its electric drivetrain, allowing it to accelerate in a low engine rev range. It also has permitted the speed range of the electric motor (the range in which the electric motor can be used exclusively) to be increased by 60 per cent compared with the current model. This means there is less dependency on the petrol engine at higher speeds, improving fuel economy.

Smaller, better electric motors
The two motor-generators are all-new and are smaller and lighter, resulting in an improved power-to-weight ratio to suit the new multi-shaft transaxle design, with no negative effect on fuel economy.

Higher motor speed and new forced water-convection cooling in place of air cooling improve the efficiency of the electric-drive motor (MG2), which delivers 53kW of power and 163Nm of torque.

Fully redesigned power control unit
A total redesign of the power control unit (PCU) has delivered a 33 per cent reduction in size, a six per cent weight saving and a 20 per cent reduction in electrical losses.

The PCU is the multi-purpose electrical heart of the vehicle, housing the inverter/voltage booster, a DC/DC converter for auxiliary power and the electronic control for the motor-generators.

In place of a belt-driven alternator the new Prius uses a DC/DC converter to recharge the 12-volt auxiliary battery by using the hybrid battery energy.

A new development allows the auxiliary battery to be charged from the hybrid battery when the engine is switched off to provide audio, window and mirror operation.

Nickel-metal Hydride battery
The new hybrid battery offers higher energy density with its total power maintained and its size reduced by 10 per cent. It can now absorb 28 per cent more energy in the same amount of time, which means that it charges faster than before.

Being more compact, the battery can be located entirely beneath the rear seats, avoiding any intrusion into the load space. It has increased cooling efficiency, regeneration range and durability. The new cooling system features an air filter in the intake bezel, which is located in the trim beneath the right rear seat.

Fuel efficiency
The fuel economy achieved by the new Prius is due to improvements in the hybrid system and efficiency improvements throughout the car. This reflects Toyota's philosophy of refining existing technology - the concept of having something good, then making it better.

Every aspect of the hybrid system has been made more efficient and these improvements deliver about half the gain that has been realised in fuel efficiency. The petrol engine uses less fuel; the electric motor-generators are smaller, lighter and more efficient; mechanical losses in the transaxle have been cut by 20 per cent; the power control unit is more efficient; and the nickel-metal hydride battery is lighter and more efficient.

The balance of the fuel-economy gains have been made by reducing the energy load of the air-conditioning system, improving the rolling resistance performance of the tyres and creating a more aerodynamically efficient vehicle design.

New-generation Prius showcases expanded safety technologies that can help avoid an accident or mitigate damage in the event of a collision

The scope of Toyota's safety package provides both grades with a Pre-Collision Safety System (PCS), All-Range Active Cruise Control, Lane Departure Alert with steering input and Automatic High Beam*.

All four technologies are based on information supplied by two key sensors, a monocular (telescope-like) camera mounted on the windscreen and a millimetre-wave radar behind the Toyota logo on the front grille.

Prius i-Tech gains the additional features of Blind Spot Monitor and Rear Cross Traffic Alert*.

Safety for the Prius begins with its TNGA-based chassis, which has been optimised for excellent impact performance.

Active safety features include vehicle stability control and electronically controlled braking with anti-skid brakes, electronic brake-force distribution and brake assist.

The fourth-generation range also features a reversing camera* with moving guidelines, emergency brake signal, Bi-LED headlamps, colour head-up display, reinforced areas around the hybrid battery and the roof, and a pedestrian-protection strategy for the bonnet and cowl.

Prius is equipped with seven airbags including driver and front passenger airbags, front-seat side airbags, full-length side curtain-shield airbags and a driver's knee airbag.

Pre-Collision Safety system
At speeds between 10km/h and the vehicle's top speed, this system uses the camera sensor and millimetre-wave radar sensor to detect vehicles on the road ahead. If it calculates a risk of a collision, it automatically warns the driver with a buzzer and alert in the multi-information display. At the same time, the Brake Assist function can provide extra braking force the moment the brake pedal is pressed. If the system determines that the possibility of a frontal collision is extremely high, the brakes are automatically applied - even if the driver does not use the brake pedal.

All-Range Active Cruise Control
This improved system makes use of the same millimetre-wave radar as the Pre-Collision Safety system to maintain a safe distance from the vehicle ahead, slowing the car to a standstill if necessary and accelerating smoothly back to the pre-selected cruising speed once the way is clear.

Lane Departure Alert with steering input
Using the windscreen-mounted camera, this technology tracks the vehicle's course between lane markings painted on the road surface. If it judges that the new Prius is about to move out of its lane without the turn indicator being used, the system sounds a buzzer and lights up a warning on the multi-information display. If the vehicle is still moving outside the lane, it will apply steering force to assist the driver to bring the vehicle back on course.

Automatic High Beam
Automatic High Beam also uses the windscreen-mounted camera. It recognises the lights of oncoming vehicles or traffic ahead, automatically switching the headlights to low beam to avoid dazzling other road users and returning them to high beam as soon as the road is clear, maximising night-time illumination and the driver's field of vision.

Advanced safety and driver assistance systems
The new Prius i-Tech is available with additional systems that support safer driving by giving the driver better real-time information about the area immediately around the car that can be difficult to see.

Blind Spot Monitor uses radar sensors mounted at the rear corners of the vehicle to detect nearby vehicles in adjacent lanes as they move into the driver's blind spot. The driver is alerted to their presence by LED warning indicators in the door mirror on the appropriate side of the car. The LED indicators will remain illuminated as long as the vehicle remains in the blind spot. If the driver operates the turn indicators, intending to move into path of the vehicle, the LEDs will flash rapidly to draw further attention to the hazard.

The same radars are used to provide the Rear Cross-Traffic Alert, monitoring approaching traffic from either side as the vehicle is reversed out of a parking space and warning the driver if any vehicles are detected.

*Reversing camera, Lane Departure Alert, Pre Collision Safety System, Rear Cross Traffic Alert, Automatic High Beam, Blind Spot Monitor and All-Range Active Cruise Control are driver assist devices only and should not be used as a substitute for safe driving practices. The area into which the vehicle is driven must be visually monitored by the driver.

Toyota's ground-breaking Prius has brought hybrid vehicle technology into the mainstream over three model generations and the new, fourth-generation of the world's best-selling hybrid vehicle matches leading-edge technology with an even greater focus on driving appeal and distinctive design.

Central to this emphasis is the all-new Toyota New Global Architecture (TNGA) platform, which enabled the Prius technical engineering team to achieve its dynamic performance goals.

This inspired the exterior and interior designers to work with more advanced and emotional forms, reflecting a new level of driving enjoyment.

Prius chief designer Shunsaku Kodama - who at 43 was Toyota's youngest-ever chief designer when appointed in 2011 - said he led a team whose youth instilled it with a natural enthusiasm to challenge the status quo.

Mr Kodama said his team focused on crafting a more powerful and engaging image for Prius, which would expand pride of ownership beyond the car's well-established environmental status.

Iconic Human-tech design concept
Prius has always been iconic with its eco performance DNA, innovative technology and instantly recognisable silhouette.

The new car's sleeker, lower form was developed under the theme of 'Iconic Human-tech', a fusion of function, playfulness and emotion.

It accentuates the lower centre of gravity while improving functional aerodynamic performance through a unique combination of curves intersecting with hard surfaces, and the subtle inclusion of smooth yet sharp character lines.

Front and centre is the Toyota emblem, located at exactly the same height from the road as the Toyota 86 sports car - a subtle pointer to the improved dynamics of the new-generation Prius.

The emblem is emphasised through a bold interpretation of Toyota's 'Keen Look' design language, characterised by a thin upper grille and sleek, sculpted headlamps.

A larger, trapezoidal lower air intake evokes Toyota's 'Under Priority' identity with a strong face that adds more character to the lower section of the car's nose.

Multi-functional, triangular design LED projector headlamps encompass high and low beams, delivering enhanced light concentration and distribution.

Fog lamps and daytime running lamps are also LED for excellent visibility and low power consumption.

Aggressive edges, extending from the headlamps around the fog lamps, make a sharp connection with the car's smooth front mass for a striking appearance.

The lower parts of the front bumper, as well as the shape of the lower grille and wheel arch, have been designed to direct airflow around and under the body.

Distinctive triangle silhouette
The profile view of the new Prius best illustrates its signature low-slung, aerodynamic form.

A distinctive triangle silhouette begins with the Toyota emblem, continues along the lower bonnet and sweeps over the top of the cabin towards the rear wing.

This cutting-edge treatment is accentuated by the decision to move the peak of the roof forward by 170mm.

The characteristic outline not only delivers a unique presence but also helps lower drag while maintaining ample head clearance inside.

An aerodynamic shark fin antenna features an aerofoil-inspired cross-section which contributes to handling stability.

Completing the triangle is the beltline, which is angled lower and forward for a sense of motion; the glasshouse intersecting smoothly with the body for a unified, yet subtly aggressive appearance.

The rocker panel features a distinctive light-catching surface that begins at the lowest part of the front bumper, flows under the door and then rises steeply to accentuate the car's low-slung stance.

Multiple strategies have been employed to channel airflow as efficiently as possible towards the rear of the car to prevent turbulence and reduce drag.

This includes the location of the roof peak, the height, length and angle of the rear spoiler, and the tapering of bodywork towards the rear corners.

Balanced integration of the low roof and rear pillar is achieved through black-out panels shaped to draw air around the side windows to the rear.

Aerodynamic performance enhanced
In addition to the signature outline, the adoption of clever design features has enhanced the aerodynamic performance of the new Prius, resulting in a target 0.24 coefficient of drag (down from 0.25).

Other aerodynamic aids include graduated vertical channels at the sides of the front windscreen to direct airflow and rain water up and over the roof without contributing to wind noise.

Aero stabilising fins applied to the front-quarter window garnish and the rear combination lamp housings control air turbulence along the side of the Prius.

Engine and floor under-covers, as well as aero stabilising fins, smooth airflow under the car.

Front spats minimise turbulence from the suspension and tyres, while under-covers on either side of the fuel tank help prevent airflow from being disturbed by the rear suspension.

At the rear, distinctive character lines and a coordinated LED lamp design add to the car's emotional appeal and distinctive presence.

The overall impression is a firm, planted stance achieved with an upper beltline and prominent rear spoiler that connect with corner edges for more efficient aerodynamics.

This unique expression, along with a low, sloping hatch, is highlighted by the vertical rear combination lamps directing the eye down and outwards to the tyres.

Newly designed wheels on both grades
Stylish, lightweight and strong 15 and 17-inch aluminium wheels contribute to the excellent dynamic and aerodynamic performance of the next-generation Prius.

The wider and more rigid 15-inch wheel is fitted with a cover to maximise aerodynamic performance and reduce weight.

The new 17-inch wheel fitted to Prius i-Tech incorporates an attractive resin insert that saves weight while improving aero efficiency.

To optimise performance and reduce road noise, wheels and tyres have been developed in tandem.

Low rolling resistance tyres help deliver significantly better fuel economy without sacrificing ride comfort, compromising handling stability or adding to road noise.

Prius is equipped with a lightweight temporary spare wheel, while Prius i-Tech is fitted with a compact flat-tyre repair kit.

A palette of seven exterior paint colours is available, including the newly developed Emotional Red - a vivid hue unique to Toyota and Prius.

It is the product of a three-stage paint process which allows light to pass through a translucent 'high chroma' permeable pigment layer and 'bounce' off embedded reflective aluminium flakes.

The result is an intense, vibrant colour with more dimension than a conventional metallic finish.

Also available are Lunar Blue, Graphite, Glacier White, Crystal Pearl, Silver Pearl and Eclipse Black.

The interior of the fourth-generation Prius has a strong presence that is advanced and functional with a high visual impact.

It embraces the "Iconic Human-tech" design concept - with a bold, futuristic and stylish cabin that offers surprising flair and simple ingenuity from its easy-to-use controls.

The latest Prius interior builds on the intuitive concept of previous generations with the dashboard's layered construction clearly defining the display zone and separating it from the control zone.

The instrument panel - with its thin, horizontal design and smooth surfaces -transitions seamlessly into the doors and then the pillars, creating a unified appearance. Soft-touch padding adds a quality feel.

A dominant centre cluster appears to have a "floating" design. The cluster features a tablet-like seven-inch touch screen. It offers "flick" scrolling of displays - a great benefit to drivers by enabling them to pay maximum attention to the road ahead.

The sound system is an impressive 10-speaker JBL unit with GreenEdge technology that achieves powerful output and excellent sound quality while being smaller, lighter and more energy-efficient than conventional audio systems.

The new-generation Prius offers a unique instrument cluster featuring two high-tech 4.2-inch full-colour thin-film transistor TFT screens with easy-to-read displays.

The main screen nearest to the driver projects vehicle speed in large white lettering and also offers ancillary information such as fuel gauge, odometer, trip meter, cruising range, average fuel consumption, outside temperature and driving mode.

An instantly recognisable background colour is used to differentiate between economical and sports driving - blue when driving in eco mode, red for power mode and grey for normal mode.

The second TFT screen is a Multi-Information Display (MID) that can be controlled from switches mounted on the steering wheel. It provides data from the hybrid system, including a range of features to encourage fuel-efficient driving such as an energy monitor, acceleration guide, driver-efficiency evaluation, fuel economy in segments (5 minutes, 1km, 5km, 1 month), an eco wallet to measure savings and an eco diary to record driving history. A range of tabs provides access to further information, including climate control and warnings such as door left ajar.

A head-up display (HUD) - full colour for the first time in a Toyota vehicle - ensures the most crucial information is always within the driver's line of sight on the lower part of the windscreen. The wide display shows vehicle speed in parallel with other information including state of battery charge, hybrid system indicator, radar cruise control and lane departure alert.

Other convenient, newly adopted technology includes a wireless mobile phone charger* (called "Qi" technology), just below the centre stack.

New air-conditioning technology saves energy, improves comfort
A new air-conditioning system adopts the latest in compact and lightweight components and technology.

Its stand-out feature is S-flow (Energy Saving Air-flow) control that, for the first time in a Toyota, automatically focuses airflow only to areas where people are seated to maximise comfort and fuel economy.

It monitors air-conditioner temperature settings, cabin temperature, outside temperature and the amount of sunlight to direct the appropriate airflow to the driver only, the front seats only or to all seats.

It detects the presence of occupants through a sensor in the front-passenger seat and by determining if one of the rear doors has been opened and closed. S-flow control can also be manually operated to give priority to the driver or passengers.

Other advances for the air-conditioning system include a new evaporator to reduce fuel use without sacrificing comfort and a new electric compressor to improve cooling performance and reduce noise.

To encourage efficient use of the air-conditioner, an eco-judge function calculates a score out of 100 every second, displaying it in the MID. After the engine is turned off, the system displays an average score and gives tips on more fuel-efficient use of the air-conditioner.

Colour and trim specialists have developed a simple and iconic black interior with the use of white as a contrast colour.

The steering-column angle has been reduced from 24 to 21 degrees for a more natural and engaging driving position while the range of tilt adjustment has been increased to accommodate a wider range of driver heights.

Switches on the steering wheel operate many of the vehicle's features, including the multimedia system, mobile phone, voice recognition, ODO/TRIP and the MID, as well as driver support systems such as radar cruise control and lane departure alert.

The combination switches have a more tactile design and the control stalks have been extended further from the steering column to make them easier to see and use. The steering wheel grip has been revised for a more comfortable, secure feel.

Enhanced peace of mind is at the heart of the Prius
Peace-of-mind inclusions in the Prius interior include excellent visibility from all seating positions, a larger-capacity boot and a comprehensive array of useful storage spaces.

The new Prius offers efficient use of interior space. Toyota has taken the opportunity provided by the more compact hybrid system and new suspension design to increase boot capacity. The hybrid battery and fuel tank have been moved from the luggage area to under the rear seat, expanding cargo capacity to 457 litres in the standard car and 502 litres in the i-Tech.

Relocating the hybrid battery and fuel tank also contributes to a lower centre of gravity and driving dynamics. Retractable hooks have been placed on both sides of the deck and there are four tie-down hooks.

Occupants benefit from a wide variety of storage areas, many of which have been enlarged or reshaped for greater useability. These include front and rear door pockets, overhead console, glovebox and the console box which now features a removeable inner tray.

Its soft-touch lid, which doubles as an armrest, is sprung and opens sideways for easier use by the driver. Two cup holders have been provided in front of the console box.

Toyota Prius has truly come of age, celebrating the 18th year of sales for the now-famous badge.

The vehicle that set out to be the forerunner of a new era of automotive environmental consciousness has become mainstream with cumulative global sales of more than 3.6 million cars.

Demand for the Prius has expanded over time. It took 11 years to reach one million sales (2008), four years to reach two million (2010) and three years to achieve three million (2013).

The first-generation Prius was shown as a concept car at the 1995 Tokyo Motor Show and released in Japan two years later as a production model.

Initially, its 1.5-litre petrol engine developed 43kW of power and 102Nm of torque for a vehicle that was small and comparatively rudimentary - but it was revolutionary.

It won Japan's Car of the Year award at launch and went on to be acclaimed around the world, arriving in Australia during 2001.

A car for early adopters, Prius also captured the attention of legislators, corporations and, as it turned out, movie stars. Hollywood adopted the Prius and gave it celebrity status.

The completely restyled second-generation Prius was launched at the New York International Auto Show in 2003.

By the time it gave way to the third-generation in 2009, it had accounted for more than 1.2 million deliveries in 80 countries.

The second-generation car was classified a Super Ultra Low Emissions Vehicle (SULEV) in California and its size and accommodation were already making it mainstream.

The third-generation Prius, again restyled, adopted a larger 1.8-litre petrol engine and was once more named Japanese Car of the Year from its 2009 debut.

The Prius nameplate was expanded into a family with the 2012 arrival of the Prius c city car and the seven-seat Prius v.

The fourth-generation Prius offers substantially improved efficiency and driveability, with cutting-edge styling and chassis dynamics that make it fun to drive.

With sales demand for the Toyota Prius running at approximately one million vehicles per year, Prius has firmly established its position as an integral part of the automotive mainstream.
