There is no defensible, like-for-like ranking of the fastest production supercars in the available research: the reported results use different vehicles, run methods and levels of verification. The clearest figures are manufacturer-published claims from Bugatti and SSC, including Bugatti’s reported 304.773 mph Chiron Super Sport 300+ run and its separate open-top Mistral record.
Those numbers should be read with their qualifications attached. A record run, a manufacturer’s stated capability and an average from a separate test are not interchangeable results.

How to compare top-speed claims
A meaningful comparison should identify the result type, vehicle status, body style, run date and location, and any stated supervision or run-specific changes. It should also distinguish a one-way result from a two-way average when that information is available.
The figures below come from the manufacturers named in the research. They do not form a harmonized independent comparison, so the order is a guide to documented claims—not a definitive ranking of all current supercars.

Reported high-speed results
| Car or result | Reported figure | What the source says |
|---|---|---|
| Bugatti Chiron Super Sport 300+ | 304.773 mph (490.484 km/h) | Bugatti reports this as a 2019 speed-record achievement by the 300+ car. The record run should not be treated as proof that an ordinary customer car has demonstrated the same result. |
| SSC Tuatara | 295 mph | SSC’s official site reports this result. The available research does not establish its precise run protocol. |
| SSC Tuatara, 2021 result | 282.9 mph average | SSC separately reports this average for a 2021 run at Kennedy Space Center. It is a distinct result from the 295 mph figure. |
| Bugatti W16 Mistral World Record Car | 453.91 km/h | Bugatti reports an open-top record run on 9 November 2024 at ATP Automotive Testing Papenburg, supervised by SGS-TÜV Saar GmbH. This was a one-off record car, not a routine production specification. |
What the Bugatti figures mean
Chiron Super Sport 300+
Bugatti reports that a Chiron Super Sport 300+ reached 304.773 mph (490.484 km/h) in 2019. Bugatti describes the Super Sport 300+ as a special edition, planned as 30 customer cars, and calls it its fastest Bugatti. The reported record achievement belongs to the record run; it should not be presented as a demonstrated result for every customer-delivered car.
W16 Mistral World Record Car
Bugatti reports that its one-of-one W16 Mistral World Record Car reached 453.91 km/h in an open-top run at Papenburg on 9 November 2024. The company says SGS-TÜV Saar GmbH supervised the run. Bugatti also says the record car received high-speed preparation: its speed limiter was removed, its suspension was set up to reduce air resistance, and body-panel gaps were masked. These qualifications matter when interpreting the result.
Rank #2
Separately, Bugatti Rimac CTO Emilio Scervo said in a 10 November 2022 Bugatti press release that the W16 Mistral would be capable of 420 km/h in “Top Speed” mode. That is a manufacturer capability claim, not the 2024 record result.
What the SSC Tuatara figures mean
SSC North America reports a 295 mph Tuatara result and separately reports a 282.9 mph average from a 2021 run at Kennedy Space Center. The research available here does not resolve the protocols into a directly comparable figure. Keep the results separate rather than combining them or treating either as an independently verified cross-manufacturer benchmark.

Why this is not a complete ranking
The available research does not establish a comparable field-wide dataset for the fastest current production supercars. It does not provide enough primary evidence to rank the many other relevant manufacturers’ cars against these results. For that reason, a numbered top-10 list would imply more certainty than the evidence supports.
For any future ranking, each entry should be checked for customer-production status, body style, run protocol, date, location, supervision and any changes made to the car for the run. A larger headline number alone does not make two results comparable.

What is the fastest supercar in the world right now?
The research does not establish a definitive, like-for-like ranking of all current supercars. Bugatti reports a 304.773 mph (490.484 km/h) 2019 Chiron Super Sport 300+ record achievement, while its separate 2024 W16 Mistral result was an open-top record by a one-off car.
Did the Bugatti Chiron Super Sport 300+ reach more than 300 mph?
Yes. Bugatti reports that the Chiron Super Sport 300+ reached 304.773 mph (490.484 km/h) in 2019. That record-run figure should not be assumed to represent a demonstrated result for every customer car.

Is the Bugatti Mistral’s 453.91 km/h result a production-car top speed?
Bugatti describes it as an open-top record by its one-of-one W16 Mistral World Record Car. The car had specific high-speed preparation, so the result is not a routine production specification.
Why are the SSC Tuatara figures different?
SSC reports both a 295 mph result and a separate 282.9 mph average from a 2021 Kennedy Space Center run. The available research does not establish a shared protocol for comparing them, so they should remain distinct claims.
Can a claimed top speed be compared with a completed record run?
Not without qualification. A manufacturer-stated capability is different from a completed measured run, and vehicle status, body style, run method and supervision can also differ. Those details should accompany the figure.
