The highest speed ever officially recorded for a production car is 331 mph (533 km/h), achieved by the SSC Tuatara in 2020. However, for production cars available to the public, top speeds are typically electronically limited to around 250-280 mph for safety and tire durability. The current titleholder for a production car is the Bugatti Chiron Super Sport 300+, which reached 304.773 mph (490.484 km/h) during a test run. It's important to distinguish between modified racing vehicles and street-legal production cars, as their capabilities differ vastly.
Achieving such extreme speeds is a battle against physics, primarily aerodynamic drag and tire limitations. As speed doubles, drag quadruples, requiring immense power to overcome it. Hypercars use advanced aerodynamics to generate downforce, which keeps the car stable but also creates more drag. Specialized tires are crucial; at speeds over 250 mph, centrifugal forces are so great that standard tires would disintegrate. Michelin and other manufacturers develop specific tires rated for these extreme velocities.
Modified vehicles, like jet-powered thrust cars, hold the absolute land speed records, but these are not cars in the traditional sense. For a street-legal vehicle you can theoretically buy, the ceiling is just over 300 mph. The table below shows the top speeds of some of the fastest production cars officially verified.
| Car Model | Top Speed (mph) | Top Speed (km/h) | Powertrain |
|---|---|---|---|
| Bugatti Chiron Super Sport 300+ | 304.773 | 490.484 | Quad-Turbo W16 |
| SSC Tuatara | 295.0 (2-way average) | 474.8 | Twin-Turbo V8 |
| Koenigsegg Agera RS | 277.9 | 447.2 | Twin-Turbo V8 |
| Hennessey Venom F5 | 301 (claimed) | 484 | Twin-Turbo V8 |
| Bugatti Veyron Super Sport | 267.9 | 431.1 | Quad-Turbo W16 |
