The highest speed limit for a car on a public road is 160 km/h (100 mph), which is found on some German autobahns.
However, the highest speed a car can theoretically reach is much higher and depends on several factors, including:
- Engine power: More powerful engines can achieve higher speeds.
- Aerodynamics: Streamlined designs with low drag coefficients reduce air resistance, allowing for higher speeds.
- Tire grip: Tires with high grip levels can handle greater forces at high speeds.
- Weight: Lighter cars can accelerate faster and reach higher speeds.
Some supercars and hypercars have achieved speeds exceeding 400 km/h (250 mph) on test tracks with ideal conditions. For example, the Bugatti Chiron Super Sport 300+ holds the world record for the fastest production car, reaching a top speed of 490.484 km/h (304.773 mph).
It's important to note that exceeding speed limits is illegal and dangerous. Driving at high speeds significantly increases the risk of accidents and fatalities.
