Does a 50-Jin Reduction in Vehicle Weight Significantly Impact Acceleration?

[LaElisa]

Reducing the vehicle weight by 50 Jin has a minimal impact on acceleration, not exceeding 2%. The key factors influencing a car's acceleration performance are as follows: 1. Transmission System: The higher the efficiency of the transmission system and the smaller the power loss, the faster the acceleration under the same engine power output. 2. Drive Type: During acceleration or hill climbing, the vehicle's center of gravity shifts backward, increasing rear-wheel traction. In such scenarios, rear-wheel-drive (RWD) vehicles demonstrate acceleration advantages. Conversely, all-wheel-drive (AWD) models exhibit unparalleled superiority when road-tire friction is low. 3. Tire Factors: Generally, wider tires provide better grip, reducing slippage during acceleration, but also increase rolling resistance.
