Speed thrills many car enthusiasts. But when it comes to what is the fastest street legal car, the answer isn’t as simple as it sounds. Different cars dominate different categories, from acceleration to top speed, and legal regulations also shape the final verdict. Let’s explore which cars are crowned as the fastest, why they hold the record, and what makes them street legal.
Understanding ‘Fastest’ – Acceleration vs Top Speed
Before diving into what is the fastest street legal car, it’s important to define what ‘fastest’ means. Some people refer to 0-60 mph acceleration, while others look at top speed.
- Acceleration defines how quickly a car can reach a certain speed from rest. For example, Tesla’s electric Plaid series focuses on extreme acceleration.
- Top speed refers to the maximum speed a vehicle can achieve. Hypercars like Bugatti and Koenigsegg focus on this figure.
In this article, fastest will mainly refer to top speed, the ultimate bragging right among performance cars.
What Makes a Car Street Legal?
A common question arises: “If a car can go 300+ mph, how is it street legal?”
For a car to be street legal, it must:
- Meet safety standards: Functional seatbelts, airbags, lighting, mirrors, and crashworthiness.
- Have emissions compliance: Must meet local and national environmental regulations.
- Include essential features: Indicators, headlights, brake lights, and other basic road-use features.
- Be registered and insured: It must be approved by a governing body (like the DMV in the US).
Cars that meet these requirements can technically drive on public roads, even if they rarely do due to practicality.
The Current Record Holder – Bugatti Chiron Super Sport 300+
When people ask what is the fastest street legal car, the Bugatti Chiron Super Sport 300+ often tops the list.
Top Speed Record
In August 2019, Bugatti’s specially tuned Chiron Super Sport 300+ hit 304.77 mph (490.48 km/h) at the Ehra-Lessien test track in Germany.
Why Is It Street Legal?
- It retains the original Chiron’s safety and emissions compliance.
- Bugatti produced a limited number of production versions for customers, making it road-registered.
- Although the record-setting version was slightly modified for aerodynamics and had a roll cage (removed in customer models), the production variant is essentially the same engine and chassis.
Specifications
- Engine: 8.0-litre quad-turbocharged W16
- Horsepower: 1,577 hp
- 0-60 mph: ~2.3 seconds
Bugatti limited the production model’s top speed to 273 mph for safety but maintains it could reach the same as the prototype under correct conditions.
Koenigsegg Jesko Absolut – A Challenger in Waiting
Another name often associated with what is the fastest street legal car is the Koenigsegg Jesko Absolut.
Projected Top Speed
- Koenigsegg claims the Jesko Absolut is designed to exceed 330 mph (531 km/h).
- As of mid-2025, an official record has not yet been verified, but the car’s engineering suggests it could beat Bugatti’s record.
Why Is It Street Legal?
Koenigsegg designs its cars to meet European and US homologation standards. The Jesko Absolut:
- Meets safety and emissions requirements
- Is produced in limited quantities for wealthy buyers worldwide
- Includes all necessary road equipment despite its aerodynamic shape
Specifications
- Engine: 5.0-litre twin-turbo V8
- Horsepower: 1,600 hp on E85 biofuel
- 0-60 mph: ~2.5 seconds
If tested officially, the Jesko Absolut could redefine what is the fastest street legal car globally.
Hennessey Venom F5 – The American Contender
Hennessey Performance, based in Texas, unveiled the Venom F5, aiming for 311 mph (500 km/h).
Key Highlights
- Engine: 6.6-litre twin-turbo V8 ‘Fury’
- Horsepower: 1,817 hp
- Projected top speed: 311 mph
Street Legal Status
Hennessey built the Venom F5 to comply with US road regulations, including lighting, mirrors, and emissions standards. Like other hypercars, it is a low-volume production vehicle but is technically street legal.
SSC Tuatara – The Controversial Speed King
SSC North America claimed the Tuatara hit 316 mph (508 km/h) in 2020, but inconsistencies in GPS data led to controversy. A later run confirmed 282.9 mph (455.3 km/h).
Specifications
- Engine: 5.9-litre twin-turbo V8
- Horsepower: 1,750 hp
- 0-60 mph: ~2.5 seconds
SSC designs its Tuatara to be street legal in the US, adding another name to the fastest cars list.
Electric Speed – Rimac Nevera
While traditional hypercars dominate top speed, electric hypercars like the Rimac Nevera focus on acceleration with a top speed of 258 mph (412 km/h).
Highlights
- 0-60 mph: 1.85 seconds
- Horsepower: 1,914 hp
