Carbon fiber wheels cut weight & boost efficiency (video)

Carbon fibre wheels are stronger & lighter to reduce:

● Wheel flex for improved handling & control — see the video above.

● Unsprung weight for improved handling, traction, & ride.

● Gyroscopic torque — see the video above, around the 6:20 mark.

● Rotating mass — a moving object has kinetic energy. In a vehicle, this energy is provided by the motor. Less energy requirement means more distance for the same cost. A lighter vehicle accelerates faster, & is more efficient, because it requires less energy from the motor to increase its speed, & so its kinetic energy. Unlike many other parts of a moving car, the wheels also have rotational energy. Once again, this energy comes from the engine. Weight saved in any part of a car improves its performance & efficiency. Weight saved in a lighter wheel improves performance & efficiency as for any other part of a vehicle, plus reduced rotational energy.
