Cars with highest downforce at 300 kph

Top 17 cars generating most downforce at 300 kph. Updated November 2020.

Most cars do not have enough engine power to overcome wind resistance at 300 kph.

This wind resistance is comprised of two components - drag and downforce. Drag is acting in opposite direction of travel and has no practical benefit. Downforce is acting perpendicular to direction of travel (pushing down on the car) and, while still limits top speed, is helping with handling performance and stability.

Unless we are comparing Formula 1 or LMP1 cars, 300 kph is beyond practical range for high speed cornering, and some supercars even use active aerodynamics to reduce downforce near top speed. It is still advisable to have some amount of downforce at top speed, to ensure stability and safety.

Since most cars do not have active aero parts, 300 kph downforce can be used as indicator for downforce levels expected at lower speeds, which matter for track performance.
