Why is the body of Toyota CHR so heavy?

The body of Toyota CHR is heavy because it is equipped with a lot of high-strength steel, which is why all cars in the Toyota Group New Global Architecture (TGNA) platform have excellent collision test results. The stability of a car at high speed is also affected by other factors, including:

1. Vehicle tires: The wider and flatter the tires, the better the stability of the vehicle at high speed.

2. Vehicle shape: The more aerodynamic the vehicle is, the better its stability at high speed.

3. Drive type: Four-wheel drive is better than two-wheel drive in terms of stability. The most common drive types are front-wheel drive, rear-wheel drive, and four-wheel drive.

4. Suspension system: Independent suspension is better than non-independent suspension. It includes types such as MacPherson independent suspension and multi-link independent suspension.

The heavy body of Toyota CHR is also the reason why it has good safety performance. In addition, the stability of a car at high speed is also affected by other factors, as mentioned above. Therefore, the body weight of a car is not the only factor that affects its stability at high speed. In summary, the heavy body of Toyota CHR is due to the use of high-strength steel and other factors such as tires, shape, drive type, and suspension system.
