FIA flying-mile outright record, the same 763.035 mph the land-speed record uses. Copied so the human-built hub can sort it. Not a second run, and not a production-car figure.
In context
Worked out from the sourced figure above, which stays the ranked number.
This list
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.
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.
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.
Provenance
Claimed, measured and official figures side by side, each with its source. The ranked figure is marked.
Top speed. FIA flying-mile outright record, two-way average, Black Rock Desert, USA, Andy Green. The FIA also states 1227.985 km/h and Mach 1.016 for this mark. A same-day kilometre record of 760.343 mph is a different distance and is not stored here.
Absolute speed. FIA flying-mile outright record, the same 763.035 mph the land-speed record uses. Copied so the human-built hub can sort it. Not a second run, and not a production-car figure.
The car list leaves this mark unranked. The hub uses absolute speed.
