As of March 2025, the fastest street-legal car in the world, based on verified top speed records, is the Bugatti Chiron Super Sport 300+.
This record was set during a two-way run at Bugatti’s Ehra-Lessien test track in Germany, adhering to the standards for official speed records, which require an average of two runs in opposite directions to account for variables like wind.
However, it’s worth noting that the production version of the Chiron Super Sport 300+ is electronically limited to 273 mph (440 km/h) for safety and practicality, though Bugatti offers owners the chance to unlock its full potential under supervised conditions at their test track. This limitation doesn’t disqualify its record, as the car tested was in its production specification, meeting street-legal requirements in multiple markets, including the European Union and the United States.
For example, the Koenigsegg Jesko Absolut is theorized to exceed 310 mph (498 km/h), but this is based on simulations, not real-world tests. Similarly, the SSC Tuatara has a controversial history—its initial claim of 331 mph in 2020 was debunked due to GPS errors, and a later verified two-way run in 2021 averaged 282.9 mph (455.3 km/h), which is fast but falls short of Bugatti’s record. Hennessey’s Venom F5 is another aspirant, claiming potential speeds over 300 mph, but it hasn’t yet produced a verified record.
It’s important to approach these claims critically. Manufacturers often push ambitious numbers for marketing, and not all records meet the rigorous standards of independent verification, like those set by the Fédération Internationale de l’Automobile (FIA) or Guinness World Records.
So, while the Bugatti Chiron Super Sport 300+ holds the crown today, the race for the fastest street-legal car is far from over, with emerging players and electric hypercars, like the Rimac Nevera (258 mph verified), potentially shifting the landscape in the future.
Fastest Street Legal Car
The Bugatti Chiron Super Sport 300+ achieved a top speed of 304.773 mph (490.484 km/h) in 2019, making it the first production hypercar to break the 300 mph barrier.This record was set during a two-way run at Bugatti’s Ehra-Lessien test track in Germany, adhering to the standards for official speed records, which require an average of two runs in opposite directions to account for variables like wind.

Other Super Fast Street Legal Cars
There are contenders, though, that challenge Bugatti’s claim, but their records are either unverified or incomplete.For example, the Koenigsegg Jesko Absolut is theorized to exceed 310 mph (498 km/h), but this is based on simulations, not real-world tests.

How did Buggati do it?
The Bugatti’s record, while impressive, was achieved under controlled conditions, and some argue that the SSC Tuatara’s real-world attempts, even if flawed, show the challenges of replicating such feats outside a perfect environment. Additionally, the focus on top speed can overshadow other performance metrics, like acceleration or handling, which are often more relevant to real-world driving.So, while the Bugatti Chiron Super Sport 300+ holds the crown today, the race for the fastest street-legal car is far from over, with emerging players and electric hypercars, like the Rimac Nevera (258 mph verified), potentially shifting the landscape in the future.
