Ranked: The 10 Fastest Street Legal Supercars

The quest to produce the world's fastest car has arguably been the main drive behind the amazing and ever-improving hypercars we see today. Following the fabled Veyron, the hypercar market skyrocketed with new and innovative solutions by companies wanting their name behind the fastest car in production. However, in the last decade, three names stood out from the rest: Hennessey, Koenigsegg, and of course Bugatti (though there will be a few surprises).

10 Koenigsegg Regera — 255 mph

After the CCX and the Agera, we knew we were in for something truly incredible when this Swedish hypercar giant announced the Regera in 2015. Its name directly translates to "reign," and it was designed to satisfy the appetite of the more luxury-oriented speed addicts with a lavish interior and a smooth ride fit for a king. Regardless of its fancy nature, the Regera is one of the most fearsome hypercars in the world. It routes up to 1500 horsepower through its hybrid powertrain fitted with a state-of-the-art 5.0L V8, which enables it to reach a top speed of 255 mph.

9 SSC Ultimate Aero — 256 mph

You're looking at the car that dethroned the iconic Veyron as the fastest production car in the world. It did so in 2007, when it officially clocked in at a top speed of 256 mph. Here's the kicker though, competing against the lavish $1.6 million Veyron, the Ultimate Aero only required you to set aside about $225,000. With that in mind, it delivers a lot more power than the Veyron, utilizing a 1287-horsepower 6.3L twin-turbocharged V8.

Apart from the more competent powertrain, the Ultimate Aero also boasted an attractive design and wind tunnel results encouraging a comparatively higher potential top speed of 273 mph. For an extreme hypercar enthusiast? Quite a bargain, we'd say.

8 9FF GT9 — 257 mph

If you haven't really heard of this record-breaker, we don't blame you. The 9ff is not your usual production car. It is, however, an absolute beast. Not only does it boast a top speed of 257 mph but reached it back in 2008. The 9ff GT9 is actually a Porsche heavily modified by a team of engineers for the sole purpose of making it go faster than any other production car. To achieve this, it's fitted with an extremely efficient 4.0L V6 churning out 1120 horsepower. It's no wonder the car has been mostly forgotten, as only 20 units have ever been produced.

7 Rimac Concept_Two — 258 mph

Here we go, the first fully-electric car to make it on this list. With the Concept_Two, this aspiring Croatian electric company is stepping into wholly new electric hypercar territory. There's a reason the fastest cars in the world still mostly use gas engines — gears make it a lot easier to build up to and maintain otherworldly speeds. However, the Concept_Two uses brute force to compete with the big boys: equipped with no less than 4 electric engines delivering a total power output of a baffling 1914 horsepower, it can accelerate to 60 in 1.85 seconds and reach a staggering 258 mph.

6 Bugatti Veyron Super Sport — 268 mph

The Veyron will forever be stamped in every car enthusiast's book as the turning point for the modern supercars and the car that brought Bugatti in the limelight. This, however, is the Veyron cranked up to the max.

Unveiled 5 years after the original model which had long been dethroned as the fastest production car in the world, the Super Sport's mission was simple: to get back what is rightfully Bugatti's. So, the team re-engineered the car to put out almost 200 more horsepower than the original, apart from additional weight and aerodynamic improvements, and clocked it in at a whopping 268 mph. It took a long seven years for the Veyron Super Sport to be dethroned by the next car on this list.

5 Hennessey Venom GT — 270.5 mph

Texas-based tuning company Hennessey cleverly took the basis of the small and aerodynamic Lotus Elise and transformed it into an utter monster. The project resulted in the Venom GT, developed with the sole purpose of claiming the title for the world's fastest street-legal car. And indeed, in February of 2014, the car hit a top speed of 270,5 mph in an impressive 2.7-mile run.

According to Brian Smith who drove the car, if GT car had more asphalt to work with, the final number would have been significantly higher. Nevertheless, the automotive community now views Hennessey with the awe they deserve.

4 Koenigsegg Agera RS — 278 miles per hour

Koenigsegg called it the "the ultimate track tool," and it was unlike anything that ever came before it. Unveiled in 2015, the Agera RS was the model's most competent version, utilizing the engineering lessons learned from the Agera R and Agera S. In that regard, it combined impressive aerodynamics with a featherlight stature and the most marvelous hybrid powertrain. In the 1MW package, the engine was able to put out 1341 horsepower, at only 2855 lbs of weight. In 2017, the car clocked in at 278 mph at a Nevada highway. But that's not all! At one point during the run, the car reached a speed of 284.55 mph.

3 SSC Tuatara — 300 mph

After the famous record-breaking SSC Ultimate Aero was brought to public attention sometime in 2007, the automotive community has been patiently waiting for its lauded successor, the Tuatara, to take the world by storm. That day is now here. And while we are still waiting for the Tuatara to officially claim the speed record, the car is already fully in production, and the company is confident enough to put its top speed at over 300 mph. To back this up is the fact that the Tuatara uses a state-of-the-art 5.9L V8 that's able to produce no less than 1750 horsepower on E85 fuel. Also, it looks like an absolute spaceship.

2 Hennessey Venom F5 — 301 mph

American high-performance tuning company Hennessey is one of the companies competing to break the iconic 300-mph barrier. That said, this car is Hennessey's definite answer to achieving this goal. But given the Chiron already took the cake, the F5 will be a bit late to the party.

The company claims a convenient top speed of 301 mph, boasting with the Venom F5's 7.4L twin-turbo V8 raging with a stampede of 1600 horsepower. It will do 0-60 in 2 seconds flat, aided by the total weight of the car that doesn't exceed 3000 lbs. The only thing that remains to be seen is if the F5 will indeed deliver on its promised speed, or perhaps even beat the fabled Chiron. Whatever the case may be, things are heating up between the world's leading hypercar manufacturers.

1 Bugatti Chiron Super Sport 300+ — 304 mph

This August the Chiron made headlines as the first-ever production car to break the 300-mph mark, clocking in at 304 mph! Winning the race to 300 mph, Bugatti once more emphasized how it's clear who makes the fastest cars and dropped the mic with a statement that they're withdrawing from competing with other manufacturers. Ouch!

As for the record-breaking Chiron, it's actually a 10-inch longer modified version, hence dubbed the "Longtail." It still uses the ridiculous quad-turbo 8.0L W16 engine we're familiar with, but this one churns out a whopping 1578 horsepower and likely features numerous more performance tweaks. The best part? Bugatti had just announced that 30 units of the Chiron Super Sport 300+ are going into production.
