Driveshafts

In Simple Terms

F1 driveshafts must be made from steel and have specific diameter requirements. The main shaft section must maintain a constant diameter, except for the final 150mm at each end where it can taper, but the inner diameter at these ends must be at least as wide as the main shaft section.

• Driveshafts must be constructed entirely from steel material
• The bore (inner diameter) must remain constant diameter for any section more than 150mm from the ends
• The final 150mm section at each end can have a smaller internal diameter, but it cannot be smaller than the constant diameter section
