(keywords: two battery life versions, pure electric platform e-TNGA, square steering wheel)
GAC Toyota bZ4X is the first global model built on pure electric platform e-TNGA, with a starting price of 199,800 yuan, representing that Toyota is challenging new forces in car manufacturing. This car's dazzling new technologies include wire-controlled steering, square steering wheel, solar panel roof, etc. So can these technologies be found in the domestic bZ4X? How is Toyota's pure electric car like? Let’s analyze in detail below.
One Motion Grip Wire Steering Technology and Half-side Steering Wheel
Toyota uses One Motion Grip Wire Steering System on the bZ4X. The steering wheel is only connected to the front wheel through wires and electronic systems. There are no mechanical parts. The steering wheel can change the steering ratio and force feedback according to speed and steering angle. The maximum angle of rotation on either side is 150 degrees, which means that the maximum rotation of left and right is 300 degrees, less than one round (360 degrees), avoiding embarrassing wrist knotting problems during sharp turns. The principle of the wire-controlled steering system is to simulate steering. After turning the steering wheel, it will not directly act on the bogie , but will send the output steering signal to the motor through the wires. The motor pulls the steering rod to complete the steering, and the second motor provides force feedback to the system, allowing you to feel the road sense and reaction force of the steering. Of course, the motor functions far more than steering input. Before processing data and sending instructions to the front wheels, the motor chip will consider vehicle speed, vehicle attitude, input speed, crosswind and road angle, etc., which is smarter than traditional mechanical connections.
To ensure safety, the system has a complete backup controller and wiring to prevent the first system from malfunctioning. The bZ4X equipped with a wire-controlled steering is equipped with a half-face steering wheel, with a wider field of vision in the front, making it easier to switch the line of sight from the road to the dashboard when driving, improving safety during driving.
In addition, the feel of line-controlled steering is also different from traditional steering. In the early stage of steering, the wheel angle rotates at the same angle as the steering wheel. In the last 10-20 degrees of stroke, the wheels significantly accelerate the steering. Although this design increases the steering angle and makes the movement on the steering wheel smaller, especially suitable for low-speed steering and parking, it needs to be adapted to prevent excessive steering. Compared with the traditional steering rack, the absence of steering column means more space is released and luggage can be placed. In addition, line-controlled steering can be upgraded remotely through OTA, updated the steering feel, and provides different steering feels with different light and heavy steering in different driving modes, which are incomparable to traditional steering.
GAC Toyota bZ4X Elite (199,800) practicality
First driving
wire steering and half-side steering wheel Although GAC has had media test drives as a engineering car inside, the first models currently launched are not equipped with this technology. They are still traditional rack mechanical steering, no different from fuel vehicles. The standard front single motor has a maximum power of 204 horsepower, the maximum torque of 266.3Nm, and the car weighs 1.86 tons. The acceleration feeling is similar to the 200,000-level fuel Toyota SUV, with an acceleration time of 0-50km/h of 3.8 seconds.
Because it adopts a new e-TNGA platform, the design idea is different from that of fuel vehicles. The battery is arranged without invading the cabin space. The thin battery unit is completely located under the vehicle floor, forming part of the chassis, reducing the center of gravity, and increasing the stiffness of the vehicle. Although it is equipped with the same front McPherson rear E-shaped multi-link suspension as the fuel SUV, and the material is also ordinary stamped steel, the front and rear counterweights are more balanced, and the overall handling experience is better.
The second ride
bZ4X has a length, width and height of 4.69 meters, 1.86 meters and 1.65 meters respectively. The size is close to the Vilanda /Rongfang fuel SUV, but the wheelbase must grow a lot, and the four wheels are closer to the corners of the vehicle, thereby increasing the internal space. The wheelbase of 2.85 meters meets the standard of a medium-sized SUV, and the second row of leg space is more spacious.
entry-level seats do not have the lumbar support and adjustment function, and the front seats also need to manually adjust the seating position, and the ventilation and heating function is only available in higher-end models.In addition, Elite also lacks functions such as voice navigation, voice control air conditioning, in-car 4G network and Wifi hotspots. If you need to choose, you can only choose a higher-end model.
security
security configuration is relatively high in bZ4X standards. The entire series is equipped with Toyota Safety Sense assisted driving system, with a level of L2. The entry-level model has functions such as tire pressure display, lane departure warning, lane centering maintenance, active braking, forward collision warning and other functions. In addition to the front and rear head air curtains, the bZ4X also comes with knee airbags standard to further improve occupant protection capabilities.
th battery life/charging
entry-level model is equipped with CATL 's 50.3-degree ternary lithium battery, and the CLTC operating range is only 400 kilometers. Now it has no advantage in 200,000-level electric vehicles. It can only be used for transportation in the city if the range is discounted in winter. It is also recommended to have a long-range version of 30,000 yuan. The battery is upgraded to 66.7 degrees and the range is 615 kilometers. In terms of charging, the 400-kilometer battery life version takes 80% of the battery capacity to charge for half an hour, and the slow charging is fully charged for 4.9 hours. highlight configuration: The solar charging roof can generate 1,750 kilometers per year, saving thousands of yuan in electricity bills, but only the top-end model can be equipped with .
Car Selection Detective Views : Toyota bZ4X's OMG line-controlled steering package is currently unavailable on the first-time models, and is expected to appear on updated models in the future. Whether it is power, battery life or intelligence, the current version has no obvious advantages in the dazzling electric car market. Do you think bZ4X can defeat the new forces in car manufacturing? Welcome to discuss.
