Until the mid-1980s Formula One engines were limited to around 12,000 rpm due to the traditional metal springs used to close the valves.

A modern-day Ferrari Formula One car being tested by Fernando Alonso at Jerez. The car is the Ferrari F10. In recent years, most Formula One teams have tried to emulate Ferrari's 'narrow waist' design, where the rear of the car is made as narrow and low as possible.

The car and driver must together weigh at least 798 kg as of 2024.
