Toyota’s Approach to Carbon Neutrality is “Practical and Sustainable”
Toyota Motor Corporation (Toyota) is striving to resolve various issues to realize a sustainable society, with the aim of passing down this beautiful Earth, our home planet, to future generations. We leverage strengths fostered through manufacturing, producing technological innovation in application to CASE to expand the potential of cars, striving to provide services that provide freedom of mobility to all, in an effort to contribute to the achievement of the SDGs.
In particular, reduction of CO2 emissions is an urgent challenge on a global scale, and Toyota is tackling initiatives towards achieving carbon neutrality (CN) by 2050. It is significant that the popularization of eco-friendly vehicles will contribute to reductions in CO2.
For this reason, Toyota believes in the idea of “introducing sustainable vehicles practically” and is developing a full line-up of electrified vehicles―comprising HEVs, PHEVs, BEVs, and FCEVs―in preparation to offer its customers a wide range of choices. Toyota aims to reduce CO2 with products that are easy to use and highly appealing.
The new BEV series, Toyota bZ, is also based on this policy. We aim to gain acceptance from many customers in regions with great demand for BEVs and plentiful supply of electricity from renewable energy, such as China, the U.S., Europe, and Japan, and plan to introduce seven Toyota bZ models by 2025.
“bZ” is New Value Provided by “beyond Zero”
With the introduction of its new bZ series, Toyota established the following four target values.
- You & Others
In addition to comfortable cabins, Toyota bZ offers a new lifestyle and the opportunity to spend precious time with family and friends.
- You & Your Car
Toyota bZ delivers the BEV’s unique joy of driving and excitement at anticipated possibilities.
- You & the Environment
Toyota bZ will not only reduce CO2 and other emissions―it aims to contribute positively to the environment.
- You & Society
Toyota bZ aims to create a safer society where everyone enjoys greater peace of mind.
The bZ4X was developed on this basis, as a medium-segment SUV-type BEV, the first model in the Toyota bZ series. Toyota will promote the deployment of BEVs in its full lineup starting with this bZ4X.
bZ4X Vehicle Overview
- Cars that are more than just a means of transport, able to provide enjoyable time and space for passengers, with the “activity hub” concept
Toyota developed the “activity hub” concept for cars that will usher in a new era, incorporating the intent to play a role in building “bonds” by being able to provide enjoyable time and space for driver and passengers alike. We are striving after innovation in all areas, including interior, styling, driving sensation and performance, aiming to create exciting cars.
- Toyota bZ4X adopts a BEV-dedicated platform (first for Toyota) based on e-TNGA philosophy, to achieve impressive driving performance through a low center of gravity and greater rigidity.
The BEV-dedicated platform (first for Toyota) which is the basis of all systems was jointly developed with Subaru Corporation (Subaru). Through this platform, which incorporates the unique requirements of BEVs with a low center of gravity and greater rigidity, we pursued off-road performance required for SUVs, with attractive, smooth, intuitive driving performance, not just for a BEV, but for any car.
- Performance Focused on Safety and Peace of Mind
Toyota was determined to offer performance focused on safety and peace of mind for new owners, as with all Toyota vehicles. In practical terms, we aimed for a BEV that can be driven safely and conveniently for many years, considering securing cruising range*2, particularly in winter settings, and targeting a top-class battery capacity retention ratio (90%*3 after 10 years). In terms of safety, in addition to pursuing a high degree of battery cell safety, we adopted the latest Toyota Safety Sense active safety package, used a body structure adapted to collision from any direction, and a battery pack that contributes to ensuring protective performance in a collision, aiming to create a BEV that provides driving safety.
| *2 | Cruising range per charge (WLTC, FWD Vehicle, in-house measurements) is approximately 500 km |
|---|---|
| *3 | Target values under development. The period of use and mileage is assumed to be 10 years, or 240,000 km (150,000 miles), whichever is shorter |
Details of the bZ4X are listed below
- More proactive initiatives―such as recycling―for reducing CO2
- Battery 3R (Rebuilt, Reuse, Recycle)
Ensures a worldwide top-class battery capacity retention ratio, as well as proactively undertakes battery rebuilt (inspection and reassembly) and reuse. Also promotes initiatives for battery recycling
- Proactive adoption of recycled materials
- You & Society
Toyota bZ4X creates a safer society where everyone enjoys greater peace of mind.

- Latest preventive safety performances
- Latest Toyota Safety Sense
In order to realize the ultimate wish of the mobility society―”zero fatalities and injuries in traffic accidents”―the bZ4X adopts the evolved Toyota Safety Sense. By expanding the detection range of the millimeter wave radar and monocular camera, we have enhanced the performance of each function and added new functions to assist on ordinary roads. The aim is to prevent accidents, further reduce traffic fatalities and injuries, and ease the burden on drivers.
- Adopts the Toyota Advanced Park advanced driver assistance technology (with remote function) (specially equipped vehicles)
- Pursues Collision safety performance expected of BEVs
- An omni-directional crash-response structure to protect passengers, batteries, and the other vehicle
- BEV unit compartment is fitted with a cross framework firmly connecting left and right front-side members to boost collision energy absorption
- Two cross-members are located in front of the vehicle to reduce harm to the other vehicle
- Strong framework created at the cabin front to achieve full under-floor mounting of the battery pack
- Adopts a structure that distributes input load over multiple routes in a collision to stabilize and protect the cabin and battery pack in frontal or side collisions
- Battery safety
- By strengthening measures to prevent and detect signs of battery failure, and introducing new technologies, have adopted a design and multiple monitoring system that ensures safety and security in case of emergency
- Thorough production process that eliminates contamination, which is a cause of abnormal heating
- Redundant monitoring of battery voltage, current, and temperature to detect signs and occurrence of abnormal heating to prevent overheating
- Newly introduced the use of high-resistance coolant, which prevents fire from short circuits even if there is leakage of the battery’s liquid coolant
- Newly introduced the use of a high-capacity battery pack integrated with the body to ensure protection in the event of a collision
- External power supply function
- DC external power supply function (Japanese specifications)
- Can connect to a power feeder to supply high-output electricity to homes and home appliances for outdoor activities, and during disasters and other emergencies
- When used with home solar power generation, solar power can supply electricity to the house in the daytime, surplus electricity can be used to recharge the vehicle via a power feeder, and electricity stored in the vehicle can be used to power the home at night
The bZ4X is scheduled for launch in all regions from mid-2022.
