Light Weight and Energy Saving
1.It is in the weight of the lighter, can be more specific than the steel wheel
2.Reduce weight by 30% to 40%. The lighter the weight of the hub, the stronger the rotation
inertia, and thus the acceleration of the car
3.The higher it is, the lower the energy requirements during braking, which means less gasoline consumption.
Examples of Audi cars, through practical experiments it was found that the same Audi car with aluminum wheels could reduce the weight by 39.5 percent compared with steel wheels.
And the acceleration from the starting speed of the car to the speed of 100Km can reduce the time.
