All-New Toyota Prius Plug-in Hybrid

The Toyota Prius introduces the unexpected for its fifth generation, with an eye-catching new chapter in its story of engineering innovation and dynamic design. Available in Europe exclusively as a Plug-in Hybrid Electric, named Prius Plug-in Hybrid in Europe, the latest Prius follows in the pioneering wheel tracks of its illustrious predecessors by once again challenging convention.

Over more than a quarter of a century, the Prius has made a lasting impact on Toyota and the world as the first mass-produced electrified vehicle, setting future EV trends and making electrified technology accessible to a wide range of customers.

The latest Prius takes the next step in that journey by introducing the enhanced electrification of the latest Plug-in Hybrid Electric (PHEV) technology to compliment Toyota’s multi-path approach to carbon neutrality which has already seen sales of more than 23 million electrified vehicles globally, with the Hybrid and Plug-in Hybrid versions of Prius alone accounting for more than 5 million units.

Toyota is committed to offering low-carbon solutions for all its customers, according to their local needs and infrastructure to ensure no driver is left behind on the road to carbon neutrality. As its most powerful and efficient PHEV, the new Prius strengthens Toyota’s line-up, which includes a commitment to battery electric (BEV) and fuel cell electric (FCEV) vehicles to offer customers a wider range of carbon reduction options.

A combination of true electric vehicle (EV) performance and all the convenience of the latest Hybrid technology delivers a dual DNA at the heart of the new Prius Plug-in Hybrid. Up to 86 km EV driving range from its 13.6 kWh battery allows fully electric driving on most daily journeys. For longer journeys, or when charging is not practical, Toyota’s new generation Plug-in Hybrid system has enhanced output and an ultra-low combined WLTP CO₂ emissions rating of 11 g/km - the lowest ever for a Prius.

Since its launch in 1997, the Prius has been heralded for efficiency but not necessarily performance. However Toyota’s fifth generation hybrid technology has the power to surprise. The hybrid system delivers an overall improvement to the driving experience, providing more power and greater efficiency. The TNGA 2.0 litre engine produces 152 DIN hp (112 kW) and works in tandem with a new 163 DIN hp (120 kW) transaxle front motor for a total system output of 223 DIN hp (164 kW). Compared to the previous generation’s 122 DIN hp (90 kW) in Plug-in Hybrid configuration, the increased output ensures strong and responsive acceleration.

Fun to drive with the latest Prius goes beyond its unexpected power and acceleration. Balance and handling have also been enhanced, thanks to the second-generation GA-C platform of the Toyota New Global Architecture (TNGA) which brings lower weight and higher rigidity for a more stable ride. A lower centre of gravity, achieved by placing the EV battery under the rear seat and moving the fuel tank lower and more forward compared to the previous generation, contributes to enhanced driving dynamics and agility.

In the quest for maximum efficiency, up to 8.7 kilometres of EV range a day (based on annual sunlight in Nagoya, Japan) can be generated by optional solar cells integrated in the roof. These now charge the plug-in hybrid battery directly, without the need for an additional solar battery as on previous models. The roof is smaller than before, but thanks to new solar cells, the overall efficiency is improved by more than 15 %.

Although the Prius has always had an eye-catching appearance, the latest generation is surprisingly stylish. The iconic wedge shape, a Prius original since the second generation, has evolved, embracing elegant modern lines. A coupé-like silhouette has been created by lowering the overall height by 50 mm, moving the roof peak rearwards and adopting larger diameter tyres, up to 19 inches.

The distinctive shape is enhanced by a 50 mm longer wheelbase compared to the previous generation. At the same time, overall length has decreased by 46 mm. The rear view is accented by a three-dimensional linear lighting element emphasising the progressive design and focusing attention on the bold Prius logo.

Inside, a spacious cabin combines driving fun and practicality for a clean interior layout. For driver and passengers alike, the interior is spacious and constructed from stylish, high-value materials, accentuated by harmonious design elements which highlight a dynamic feel and sense of purpose.

The driver’s view is based around the seven-inch screen which sits directly in the field of vision, enhancing safety by keeping a driver’s eyes on the road. A newly-designed instrument panel prioritises cabin comfort and a clean lay-out for minimal intrusion into the driver’s forward vision, usability and appearance. It combines a discreet, lower central screen to access Toyota’s latest cloud-based multimedia system, and slim air conditioning controls.

As well as delivering the unexpected in terms of performance, efficiency and aesthetics, the new Prius is also a pioneer when it comes to innovative technologies. One example is the Toyota T-Mate, which incorporates the latest generation of Toyota Safety Sense (TSS) and can now be conveniently updated over-the-air.

An enhanced front camera and radar can see further ahead and boast a wider lateral and vertical view, allowing the detection of more objects, as well as identifying a wider range of potential hazards, including motorcycles and roadside objects. Front side radar sensors are added to support the Pre-Collision System, Lane Trace Assist and Front Cross Traffic Alert features for added peace of mind.

Once at the destination, the new Prius takes the stress out of parking too, thanks to the semi-autonomous Advanced Park system, which can park hands-free or via remote control.

Powertrain

• Third generation Plug-in Hybrid Electric powertrain is more compact yet more powerful.
• 100 DIN hp (74 kW) total system output increase compared to previous generation.
• Newly-developed 2.0 litre engine (152 DIN hp / 112 kW) and new transaxle front motor (163 DIN hp / 120kW) for a total system output of 223 DIN hp (164 kW).
• 50% higher battery density but 30% fewer cells.

The new Prius is the first vehicle to utilise both the TNGA 2.0 litre engine and the third generation of Toyota’s Plug-in Hybrid system, which has benefited from continuous improvement since the first Plug-in Hybrid Prius was launched in 2012. The engine has increased displacement compared to the 1.8l unit used on the previous generation and achieves a very high 41% thermal efficiency.

Toyota’s experience of electrification has been deployed to create a Plug-In Hybrid powertrain which is more powerful and more fun to drive, despite being lighter and more compact, whilst simultaneously delivering better efficiency in terms of fuel economy and emissions. 

Total system size and weight have been reduced for a more compact powertrain package. For example, removing the one-way clutch between the two electric motors was made possible by a new high output, low loss drive motor that delivers excellent acceleration performance, lower fuel consumption and contributes to wide-ranging packaging improvements.

The system uses a new Power Control Unit (PCU), which includes an integrated, higher output DC-DC converter, required to convert voltage, and operates at a modified frequency to reduce cabin noise. The unit, fitted directly on top of the transaxle, provides 120% of the output of the previous model. The transaxle itself deploys 60% more power than its predecessor but at 20% less weight because of shape optimisation.

A dry sump system has been adopted to reduce dynamic transmission fluid levels and provide optimal lubrication while low-viscosity oil reduces internal friction and contributes to an all-round improvement of transmission efficiency.

System output has been enhanced via an increased battery capacity, from 8.8kWh to 13.6kWh. The lithium-ion battery has a higher energy density, giving 50% higher capacity but using 30% fewer cells, allowing the battery pack to be shortened and installed below the rear seat.

Use of a higher-capacity battery also enables the introduction of Regeneration Boost for stronger deceleration and greater energy recovery. The driver can select one of three regeneration different modes - gentle, medium and strong - to enjoy a more relaxed drive, with up to around 80% of deceleration achieved without the need to apply the brake pedal.

When parked up, a 3.3 kW on-board charger can top up the battery from standard 220V mains electricity from zero to full in just four hours.

Those all-round enhancements to the Plug-in Hybrid powertrain have resulted in the most powerful and high performing Prius yet, as well as the most efficient. A 100 DIN hp (74 kW) increase takes total system output to 223 DIN hp (164kW) and helps the new Prius accelerate from standstill to 100km/h in 6.8 seconds thanks to 190 Nm of torque. For the most efficient grade, fuel consumption is just 0.5 l/100 km and the combined CO₂ emissions rating is an ultra-low 11 g/km, according to WLTP test standard.

Design

The iconic wedge shape has been reborn for the fifth generation with a progressive design which retains an unmistakable Prius look within a sleeker, sportier silhouette.

The elegant roof line reaches a peak towards the rear of the vehicle, behind the driver’s door, and this subtle change is made more impactful by a 50 mm reduction in height compared to its predecessor. A 50 mm longer wheelbase and overall length reduction of 46 mm combined with larger, 19 inch, diameter tyres complete a new, coupé-like look.

New and exclusive aluminium wheels are standard on the new Prius, with dynamic design intended to regulate airflow along the side of the vehicle for better stability. They stand out with stylish black and bright machined finish.

Clean lines and surfaces are inspired by the natural flow of air and exterior shapes have been optimized to enhance aerodynamic efficiency for effective handling, whilst reducing wind noise. Front grille shutters optimize the inflow of air, contributing to cooling, while the front and rear bumper shapes have been designed to smoothly channel air around the car, concluding with an elegant rear spoiler.

Form follows function at the front, which creates a distinctive face for the new Prius, showing the new design language for Toyota.

The new Prius’ identity is imposed through the bold, centrally placed vehicle name at the rear with progressive spaced lettering which sits beneath an unconventional three-dimensional linear rear light. Other subtle Prius logos are visible throughout the vehicle and emphasise an attention to detail.

Two new colour options are available. The understated yet eye-catching Ash and vibrant Mustard expand the colour palette to seven, joining Dark Blue, Emotional Red, Platinum Pearl White, Silver Metallic and Attitude Black.

A panoramic roof enhances the natural light within the spacious cabin, complimenting the open feel generated by Toyota’s new “Island Architecture” framework.

The driver sits behind a newly designed, small-diameter steering wheel, which at 350mm contributes to the fun to drive sensations. A seven-inch Thin Film Transistor (TFT) LCD full-graphic screen sits directly in the driver’s field of vision, minimising distraction, while an intuitive Human Machine Interface (HMI) provides a high level of visibility for important data by simplifying the information displayed.

Distinctive accents on the instrument panel and the synthetic leather seats are colour coordinated and work in sympathy with the black-themed interior to add a dynamic aspect to the surroundings. Bezel-less, modular type switches enhance the high-quality appearance while a new interior lamp uses LEDs for wider illumination and modern appearance.

The new Prius’ interior is practical as well as stylish. Cabin storage has been optimised for better usability and capacity, highlighted by a 7.0 litre glovebox – compared to the previous 5.4 litre – and revised console storage, which now opens from the rear to allow easy access for both driver and passenger. Luggage compartment space has also increased, from 251 litre to 284 litre (VDA), thanks to the relocation of the battery pack.

Red Dot Design Award 2023

Even before the fifth-generation Prius rolled onto European roads, it was already a winner having received the prestigious Red Dot Design Award for Toyota’s elegant and modern reinterpretation of the iconic wedge shape.

The unique design, a signature of the Prius for more than a quarter of a century, has been taken to a distinctive new level by a coupé-like silhouette and unexpected sporty touch. In the predominantly black, spacious interior, select materials provide a stylish and harmonious ambience. The redesigned instrument panel contributes to comfort and safety with its clear and uncluttered layout where easy-to-read instruments allow for simple and ergonomic operation.

With around 20,000 entries annually, the Red Dot Design Award is one of the largest design competitions in the world and for over 60 years has honoured innovative design in the categories ‘Product Design’, ‘Communication Design’ and ‘Design Concept’. The new Prius was given the highest award, ‘Best of the Best’ for 2023 in the category ‘Product Design’ after an evaluation of all entries by an international jury comprising 43 members.

Platform

• Second generation TNGA philosophy delivers improved handling and stability.
• Lower centre of gravity via optimised battery lay-out.
• More rigid body structure enhances passive safety.

The new Prius is built on the second-generation Toyota New Global Architecture (TNGA) philosophy and the new GA-C platform, continuing the trend set by its predecessor. Previous generation Prius was the first vehicle worldwide to be built with the TNGA philosophy. The latest generation delivers benefits in terms of handling responsiveness, steering engagement and ride quality as a result of its lower weight and higher rigidity.

Individual components have been optimised to further contribute to handling and comfort targets. For example, the rear pillar frame design has been optimized to increase rear torsional rigidity by 30% compared to the previous model. Cold stamp super high-tensile steel, as opposed to hot stamp material used in the past, provides both weight reduction and high body strength. In a world first for Toyota, 1470 Mpa steel has been adopted, reducing the bodyshell weight by 24 kg. Other strategic selection of materials means the roof is now almost 1.5 kg lighter, and each rear door is more than 500 g lighter.

Moving the battery pack under the rear seat and adjusting the fuel tank position to be lower and more forward compared to the previous generation achieves a lower centre of gravity. That, combined with the optimisation of under floor part shapes to enhance air flow, achieves a more stable driving feel and the sensation of a closer connection to the road surface.

Newly designed suspension – MacPherson strut type at the front and suspension and trailing arm type double-wishbone at the rear – also promote handling performance as well as ride comfort and quietness.

An additional benefit of the GA-C platform’s increased rigidity is its capacity to absorb and disperse impact forces effectively in the event of a collision. Strong but lightweight ultra-high-tensile materials are applied and reinforced in key areas.

In line with Toyota’s aims to continuously move towards a carbon neutral future, the new Prius includes some parts made from recycled materials, while both bumpers and other mouldings are constructed from Toyota Super Olefin Polymer which can be easily recycled.

• Features
• Optimised fuel efficiency via Predictive Efficient Drive.
• Clean energy via solar charging.
• Enhanced entertaining, navigation, including Apple CarPlay and wired Android Auto connectivity.

The new Toyota Prius comes with a range of features to make driving easier, more efficient and more entertaining than ever.

Fuel economy is enhanced thanks to the new Predictive Efficient Drive system which learning a driver’s regular routes and driving style, and automatically optimises the use of full-electric mode to minimise consumption. Additionally, navigation system data identifies regular locations for sudden deceleration, where regenerative braking is automatically increased to maximise energy recovery. When highways or uphill sections are approaching, which require additional power, the system proactively selects Hybrid mode to charge the battery for the upcoming high demand, further enhancing practical fuel efficiency. The system becomes increasingly effective as the amount of data available increases with the number of kilometres driven, enabling ever more efficient use of electrified power.

That electrified power can again be generated cleanly by optional solar cells on the roof, which charge the new Prius when it is parked outdoors in sunlight. Power output is increased to 185 W, from 179 W, and the cells are now capable of generating power for up to 8.7 km (based on annual sunshine in Nagoya, Japan) of EV driving, without infrastructure or electricity costs. The battery can therefore be fully charged if the car remains parked for just over a week.

The solar cells now charge the main battery directly, without the need for an additional solar battery as on the previous generation. Thanks to more efficient cells, the power generated by the Solar Charging roof is 15% higher than before, despite a smaller roof.

The new Prius also features a multimedia package including access to a cloud-based navigation system, which uses constantly updated real-time traffic event information for accurate and efficient route planning. Route information is downloaded in advance to enable seamless navigation even when the system is not connected to the cloud.

Users can access smartphone navigation services wirelessly via Apple CarPlay® or using a USB via Android Auto®, while the multimedia unit also includes a built-in web browser for music and video streaming or staying up to date with the latest news.

Selecting multimedia functions via voice commands has been made easier with the “Hey Toyota” on-board voice agent. This will respond to spoken requests from the driver or front seat passenger to adjust the climate control, choose multimedia options, make a phone call, or open and close the windows. “Hey Toyota” is designed to understand conversational speech, so the command “I’m hungry” will generate restaurant recommendations in the area, for example.

In addition to the pre-set Normal, Eco and Sport modes familiar on most Hybrid and Plug-in Hybrid vehicles, the driving experience on the new Prius can be customised via the Drive Mode Select option on the centre console. Depending a driver’s preference, a customised combination of powertrain, steering and air conditioning settings can be saved for instant access at any time.

Driver Assist and Safety

• Latest generation Toyota T-Mate, including updated Toyota Safety Sense technology.
• Hands-free and remote-control parking possibilities with Advanced Park System.
• New driver monitor camera highlights distraction or fatigue.
• Enhanced Road Sign Assist includes excess speed alerts.

The Prius comes with the latest generation of Toyota’s T-Mate system and Toyota Safety Sense, which includes new driver assist and accident prevention features whilst expanding existing capabilities to enhance safety, convenience and peace of mind.

The semi-autonomous Advanced Park System allows easier and safer parking, and can conveniently memorise regularly used spots, such as at home or the workplace. Using its four Panoramic View Monitor cameras and 12 ultrasonic sensors, the Prius can manoeuvre, hands-free, into a space, with the driver only required to check surroundings and shift when prompted. In certain conditions, remote control operation is also possible, allowing the driver to step out of the car and initiate parking using a smartphone.

Other T-Mate functions enhance a driver’s awareness via features such as the Panoramic View Monitor which provides an all-round view of the vehicle’s immediate surroundings during low-speed manoeuvres; Blind Spot Monitor and Rear Cross Traffic Alert with Automatic Braking, which warns of traffic and hazards when overtaking or reversing.

Thanks to the new driver monitor camera, the status of the driver is constantly monitored for any sign of distraction, excessive fatigue or medical emergency. An audible alert will initially sound to prompt the driver and, when Lane Tracing Assist is activated, an Emergency Stop Driving System can safely bring the vehicle to a halt if the driver does not respond by steering, accelerating or decelerating within a pre-defined time. The effectiveness of the pre-collision system is also enhanced by considering a driver’s status when a potential hazard is detected and adjusting its reaction accordingly.

An expanded Road Sign Assist (RSA) function further supports safe driving by recognizing signs on the road ahead and displaying these on the instrument panel. In compliance with the latest European Union regulations, a driver is notified, visually on the display and by an audible alert, if they exceed the stated speed limit or overlook a ‘no entry’ sign. The Adaptive Cruiser Control (ACC) speed can be reset with the push of a button to respond to changes in the speed limit indicated by the RSA, while a speed limiter option can additionally be selected to prevent acceleration beyond a driver-defined speed.

The ACC system has been updated and now also features a fourth setting for the following distance, compared to from the previous three. Enhanced vehicle detection allows the identification of more than one preceding vehicle, as well as those in adjacent lanes, helping the system to support highway overtaking by adjusting speeds in line with traffic conditions, especially when changing lanes. It also includes a new function to prevent inadvertent undertaking. 

An enhanced front camera sensor array now has double the forward detection distance and a wider lateral and vertical view, allowing it to detect objects earlier, as well as identifying a wider range of potential hazards, including motorcycles and roadside objects.

By upgrading the performance of millimetre-wave radars at the front, an expanded detection range can now monitor objects closer to the front of the vehicle than previously. The new sensors have improved the detection capabilities of the Pre-Collision System, adding the capability to detect a motorcycle in addition to pedestrians and cyclists.

Lane Departure Alert with Steering Assist now has enhanced lane recognition including detection of objects, such as walls or barriers, to help the system define a lane. Lane recognition is also enhanced for the Lane Tracing Assist system which now helps ensure more space between vehicles being overtaken in adjacent lanes by offsetting the vehicles’ driving path with minor steering adjustments while keeping the vehicle within its lane.

Proactive Driving Assist is another new Toyota Safety System feature. It supports drivers with gentle braking into corners or braking and/or steering to maintain a safe distance between a vehicle ahead, pedestrian or cyclist, using the vehicle’s camera and radar.

The new Prius is also equipped as standard with a front centre airbag that helps prevent contact between front occupants during a collision.

Enriching Toyota’s Vision Towards Carbon Neutrality

• New Plug-in Prius brings enhanced electrification to a wider range of European customers.
• Plug-in Hybrid Electric is a fundamental part of Toyota’s multi-path approach.
• A pragmatic use of raw materials for batteries, enhancing customer choice on the road to carbon neutrality.

As the pace of electrification accelerates, Toyota expects to sell 5.5 million electrified vehicles a year worldwide by 2025, with a line-up of 70 models, including 15 zero emission vehicles (ZEV).

Toyota is a “full line-up” manufacturer of vehicles, including Hybrid, Plug-in Hybrid, FCEV and BEV options, that can bring electrified mobility to all customers. This multipath  approach allows Toyota’s customers in countries and regions worldwide, to reduce their carbon footprint today, no matter what their local infrastructure, environment and daily needs might be.

Toyota forecasts 90% of its Western European sales will be electrified vehicles by 2025, of which at least 10% will be ZEVs. This figure will increase to 100% electrification by the end of the decade, with at least 50% ZEVs, or greater if market demand and infrastructure permit it. By 2035 a full 100% reduction in new vehicle CO₂ emissions, potentially earlier in some individual national markets, is Toyota’s target.

The elimination of carbon emissions figures strongly in Toyota Motor Europe’s commitment to achieving complete carbon neutrality in Europe by 2040.

As an important step towards complete carbon neutrality, all manufacturing sites in Europe will be carbon neutral by 2030. It includes minimising energy consumption wherever possible, switching to green energy, and implementing kaizen innovations to reduce CO₂ or eliminate it entirely.

By 2035, Toyota aims to reach 100% CO₂ reduction in tank to wheel emission, and by 2040 latest, activities outside of the company’s direct control, such as upstream supply and logistics, should be carbon neutral.

In the spirit of its pioneering predecessors, the new Prius represents an essential element of Toyota’s vision to reach zero carbon emissions by offering customers more choices to reduce their environmental impact in line with their local needs and possibilities.

Toyota is committed to leaving no motorist behind on the journey towards carbon neutrality. Hybrid already has proved a practical steppingstone in the growing trend towards electrification, emphasised by a record high 72% of electrified vehicles sold by Toyota Motor Europe in Western Europe in the first five months of 2023. 

With most Toyota models now featuring a Hybrid option, the next practical way to increase electrification for customers without easy access to the relevant infrastructure is Plug-in Hybrid technology. The new Prius, available exclusively as a Plug-in Hybrid in Europe, caters to their needs by offering enough range for daily EV driving, in combination with Hybrid convenience for longer journeys or when charging is not available.

The infrastructure to charge a battery electric vehicle (BEV) or fuel cell electric vehicle (FCEV) is still evolving globally, including in Europe, and many areas lack practical solutions for those customers wishing to move faster towards greater electrification. The new Prius is a pragmatic solution which bring EV daily driving within reach, whilst its efficient use of resources means the batteries in six Prius Plug-ins use the same amount of precious raw material as just one 80 kWh BEV.

The Next Chapter in a Hybrid History

The Prius has come a long way in every respect since its launch in 1997, and the fifth generation takes the legacy to a new level whilst building on a philosophy of pioneering technology and Toyota’s commitment to a brighter future.

The original Prius started the ball rolling on electrification as the world’s first mass-produced hybrid electric vehicle, fittingly launched with the tagline “Just in time for the 21^st Century” and it initially caught the eye thanks to its quirky sedan styling.

On closer inspection the new hybrid technology was the real standout. A specially designed VVT-i 1.5l petrol engine and compact, high-torque electric motor provided driving performance comparable to that of existing similar-sized cars, but with double the fuel efficiency and half the CO₂ emissions.

Those figures helped Prius become Japanese Car of the Year honour in 1997-98 before it hit the world stage when exports began in 2000, quickly creating a close bond with environmentally-conscious consumers in Europe and the United States.

A completely new, second-generation Prius was introduced in 2003 and brought with it new aerodynamic standards, with an ultra-low 0.26 drag coefficient, and the iconic wedge shape, achieved as a result of the move to five-door hatchback format. This generation was also awarded the Car of the Year title for Europe in 2005.

Hybrid technology was evolving fast and the new Toyota Hybrid System II in the second-generation Prius achieved 15% greater efficiency, and 50% more power from the electric motor, now utilised to enhance performance as well as efficiency. An improved battery pack, with reduced weight but increased output, enabled the Prius to drive on electric power for up to 2 kilometres.

True to its original mission as an inspiration for a new style of motoring, the second-generation Prius drove Toyota’s hybrid sales beyond the 1 million mark, making a meaningful impact on emissions reduction worldwide.

Toyota’s hybrid leadership was further strengthened in 2009 via the third generation Prius, which arrived as the world’s most technically advanced mainstream car, increasing fuel efficiency by another 10% and reducing CO₂ emissions by 14% thanks to an even lower drag coefficient, a larger 1.8l engine and redesigned electric motor.

Customers could now enjoy smooth, stress-free hybrid driving in new Prius family members as well, courtesy of more powerful lithium-ion battery packs. The Prius Plug-in, introduced in 2012 as one of the very first Plug-in Hybrids in Europe, could also be charged from an external power source, allowing drivers to enjoy the benefits of all-electric motoring with the reassurance and reliability of Hybrid. With its 25 kilometres of EV range and class-leading efficiency, the first Prius Plug-in Hybrid set a new benchmark in terms of mobility.

Prius continued its role as Toyota’s path-finder, for Hybrid technology and beyond, with the fourth generation, which was launched in 2015 as the very first vehicle to utilise Toyota New Global Architecture (TNGA).

TNGA contributes to making Prius, and many subsequent models, more fun to drive by achieving a low centre of gravity for a more engaging driving position, and less body roll. More responsive handling came also from the use of high-strength steel which made the fourth generation Prius bodyshell 60% more rigid than its predecessor.

Another engineering milestone was reached on the fourth generation Prius. Its new engine delivered an unprecedented maximum thermal efficiency of 40%, the highest figure yet achieved for a mass-market petrol engine. A new Plug-in Hybrid version was also introduced, with an EV range of 50 kilometres and a CO₂ per kilometre-value of only 22 grams according to the previous NEDC driving cycle.

Such technical breakthroughs are integral to the model’s position as the inspiration for Toyota’s leadership in electrification, one that is strengthened by the fifth generation, exclusively a Plug-in Hybrid for Europe.

Since the introduction of Prius in 1997, Toyota has sold more than 23 million electrified around the world. More than 5 million of those are Prius and Prius Plug-in Hybrid.
