Why it's so fast

A car is fast when the force pushing it forward still beats the air, and when the tires and the gearing can use that force. A limiter is a different fact from an unlimited run.

  1. Drag and gearing

    Top speed is the balance point: thrust equals aerodynamic drag. The gearing has to still be pulling when the car gets there, or the engine falls off its power.

  2. What the sources signed

    A manufacturer claim, a magazine test and an electronic governor are not interchangeable. The measurement line says which one this page ranked.

A limited example is the Bugatti Chiron.

This is how the category works. A note written for this entry appears here once it is in the database.
