Toyota released details of the SUV type "bZ4X (BZ4X)" as the first bullet in the new EV "bZ" series on October 29th. It can travel up to 500 kilometers on a single charge. From the middle of 2022, it is planned to be listed in Japan, North America, China, Europe and other parts of the world.

The "bZ" series is a dedicated platform EV aimed at "beyond Zero (more than zero value)". In China, the United States, Europe, Japan and other regions with more EV demand and renewable energy power supply, in order to make the majority of users accept, it is expected that seven models will be introduced by 2025.

EV Special platform with low Center of Gravity and High rigidity

Toyota bZ4X Toyota and Subaru jointly develop all basic EV dedicated platforms. Join the unique requirements of EV, using a low center of gravity, high rigid platform. In order to achieve low gravity, Toyota uses a thin large capacity battery pack with total power 71.4kWh for the first time. In addition to the under-floor and flat configuration, it also integrates the e-Axle of motor, drive axle and inverter, and the electrical supply unit (ESU) which integrates charging function and power distribution function.

In order to achieve high rigidity, in addition to adopting the body structure which uses hot stamping material and high tension steel plate in the main frame, it also seeks to improve the rigidity of the battery pack and its periphery, BEV unit, radiator carrying part, front and rear suspension and so on.

The FWD car of the motor is equipped with a maximum output 150kW AWD in front and a maximum output 80kW before and after each. The acceleration of 0-100km is FWD 8.4s and AWD 7.7s. Fast response, linear acceleration sense, plus acceleration and deceleration control, reduction of driver's pedal operation, skid suppression control of slippery road, etc., achieve high-precision output control.

The AWD car improves its turning back and handling stability through the independent control of the front and rear motors. At the same time, the new Subaru vehicle integrated control technology "X-MODE" with ground grip control is adopted. The use of motor-driven features, from daily use to light cross-country driving, to achieve the high running performance expected by EV.

(I) ensure that the charging mileage is about 500 km

In addition to pursuing aerodynamic performance and lightweight body units, Toyota bZ4XbZ4X also uses heat pump air conditioners, seat heaters, steering heaters and radiation heaters under the feet of front seat occupants to restrain the power consumption caused by winter heating. A charging distance (WLTC mode) FWD car about 500km, AWD car about 460km to ensure. In addition, it is set to generate rooftop solar panels equivalent to 1800 km of driving distance within a year. Contributes to excellent endurance distance.

It is also equipped with DC external power supply function. In emergency situations such as outdoor or disaster, power can be connected and high-power electricity can be provided to houses and household appliances. In addition, it can also be used with household solar power generation, which supplies electricity to the home through solar power generation during the day, and the remaining electricity charges the vehicle through the power supply. in addition, the electricity collected in the vehicle can also be used as home electricity at night.

It also supports high-power charging in all regions of the world. DC fast charging supports 150kW charge up to 80% in 30 minutes.

BZ4X uses a designed and multiple monitoring system to ensure safety and safety, just in case, by strengthening measures to "prevent" and "detect" battery failures, as well as the introduction of new technologies. A thorough manufacturing process to eliminate foreign body contamination is designed to avoid abnormal heat, even if the foreign body causes abnormal heat mixing in the cells. Multi-channel monitoring of battery voltage, current and temperature. Detect signs of abnormal fever to prevent fever.

Taking into account the uniqueness of EV and the power of SUV

Toyota bZ4X design theme is "Hi-Tech and Emotion". The styling challenge of combining the advanced sense of EV with the original beauty of the car is aimed at the modeling of the coexistence of advanced slimness and the power of SUV.

The side view uses the long wheel distance of the tires placed in the four corners to achieve the new outline by combining the slim scale and improving the SUV style. The front view uses a theme and different designs that symbolize the central emphasis of the traditional car radiator. The corners into which the aerodynamic project is woven, the thin bumper shape, and the continuous characteristic hammerhead shape from the hood to the upper part of the headlight emphasize the uniqueness of the EV. The rear combination lamp, the back door and the bumper, as the trapezoidal theme towards the tire, show a low center of gravity and powerful posture.

A spacious and open interior space

Toyota bZ4X has a full length of 4690 mm, a width of 1860 mm and a full height of 1650 mm. Through the EV dedicated platform, create a spacious interior space on the first level. Make sure the distance between the front and rear seats is the same as the D-segment sedan, which is 1000 mm. Underfoot is also the breadth of the intermediate SUV level and the highest level. The fabric dashboard is set in a lower position to create a quiet room with a sense of release. The glass with high sound insulation, the reduction of wind noise, etc., and the possible silence of the clear dialogue while driving is also ensured.

The cockpit is the first time Toyota has installed the instrument through the top visible on the upper side of the steering wheel. The line of sight is less and far-sighted, and attention is paid to visibility. Modular to facilitate the operation of driving operating systems, including steering columns. It takes a shape like a feather coat, prompting the instrument to guide the line of sight from the hand.

The information system uses connection navigation to make full use of the map information on the cloud to obtain real-time traffic information and free information of the parking lot. In addition to the usual navigation functions, EV-specific functions such as mobile support, charging facility display, and endurable area display are also supported.

Pursue preventive safety performance and collision safety performance

BZ4X uses the evolved Toyota sense of security. By expanding the detection range of millimeter wave radar and monocular cameras, new functions are added to improve the performance of various functions and provide support on the general road.

At the same time, the omni-directional collision response structure is adopted to protect the occupants, the battery and the car colliding with each other. The cross skeleton which firmly connects the left and right front longitudinal beams is set up in the EV cell, which improves the energy absorption efficiency of the collision. Two crossover parts are arranged in front of the vehicle to reduce the harm to the other vehicle. In order to install the entire battery pack under the floor, a strong frame is formed on the front side of the engine room. In order to protect the engine room and battery pack stably in frontal collision and side collision, the structure of dispersing the input load in multiple paths is adopted.
