The first is power design. Engine power is the product of speed and torque. The truck uses a low-speed, high-torque diesel engine, which improves the towing capacity at the expense of speed (low top speed). Cars are just the opposite. The gasoline engine has high speed and relatively small torque, which is more suitable for the needs of small load and high speed. For example, the 430-horsepower BMW M4 has a maximum torque of 550Nm. FAW J6P's 11L engine has 420 horsepower and a maximum torque of 2100Nm. The second is the body structure. The truck uses a non-load-bearing body with leaf springs and an integrated axle structure, which increases the load-bearing capacity but sacrifices the ability to filter road bumps (comfort). On the contrary, for cars, the load-bearing body reduces the weight of the car and cooperates with coil springs and independent suspension to greatly improve acceleration, handling and comfort.
