What are the fastest cars in the world? These cars push the boundaries of speed, performance, and engineering to give us some impressive figures.

There’s a distinction between quick and fast. Quickness is tested using the time it takes a car to reach 60 mph from a standstill, also known as the 0-60 mph test. The test of the fastest cars is based on their top speed. This is the speed a car can achieve when it has plenty of room to drive straight and push the boundaries of its build and engineering. With that in mind, these are the fastest cars in the world.

Koenigsegg CCXR – 249 MPH

The Koenigsegg CCXR is an incredible car, pumping out 1004 horsepower, which is an incredible upgrade over the CCX, which produces 795 ponies. The CCXR was modified to run on E85 gasoline and uses the same 4.7-liter twin-supercharged V8 engine as the less powerful version. This car has the engine, aerodynamics, and build to take on many cars and leave them far behind. This isn’t the first high-speed Koenigsegg; the CCR broke the top speed record in 2005, but the CCXR is even faster.

SSC Ultimate Aero TT – 256.18 MPH

The name SSC stands for Shelby Super Cars, giving you a better idea of where this car comes from. The Ultimate Aero TT is one of the fastest cars in the world, besting the Bugatti Veyron in 2007. The Aero TT includes an impressive twin-turbocharged V8 engine that produces 1,287 horsepower and a theoretical top speed of 290 mph. That said, this car hasn’t hit that mark or the potential 270 mph that SSC says it could hit with a long enough road.

Bugatti Veyron Super Sport – 267.81 MPH

When SSC beat the Veyron’s top speed, Bugatti added larger turbos and intercoolers to produce 1,200 horsepower from the 8.0-liter quad-turbocharged W16 engine. This boost resulted in the Veyron Super Sport hitting a higher top speed than the previous version of this car. Only 30 models of this car were produced, but that was enough to satisfy the market and give us a car that sits in the fifth spot among the fastest cars. Bugatti also upgraded the chassis and suspension to handle the increased speed and power in the Super Sport.

Bugatti Chiron – 261 MPH

Taking a little bit of creative license, we’re pretty certain the Bugatti Chiron could easily best the Veyron when both have the speed limiter removed. To date, the Chiron hasn’t run without the limiter because tire manufacturers haven’t built tires that can handle the expected top speed of this car. The expected result, when the right tires are available, is this car will top 300 mph. The Chiron produces 1,479 horsepower from the same massive engine that powers the Veyron Super Sport.

Hennessey Venom GT – 270.49 MPH

Using a 7.0-liter twin-turbocharged V8 engine, the Hennessey Venom GT is one of the fastest cars in the world. This car hits the third spot in the ranking with its incredible top speed and 1,244 horsepower. The Venom GT is also the fastest-accelerating production car, reaching 186 mph in 13.63 seconds. Hennessey claims the Venom GT can reach 278 mph if it has more room to push the limits of roads that aren’t long enough and straight enough to give this car room to reach its full potential.

Koenigsegg Agera RS – 277.87 MPH

The Agera RS takes some of the advanced tech from the One:1 and adds goodies from the Agera S to create a car that delivers the power to reach the runner-up position in the world of the fastest cars. This car produces 1,341 horsepower from the 5.0-liter twin-turbocharged V8 engine. Most owners receive models that produce 1,160 horsepower, but eleven owners checked the “1MW” special packaging box, which increases the power to 1,341 horsepower. This car sits in the second spot on the list but is no longer produced by Koenigsegg.

SSC Tuatara – 282.9 MPH

The SSC Tuatara isn’t new to the world, it’s been part of conversations since 2011. This car is the world’s fastest car right now. With speed limiters removed, this supercar became the fastest production car by clocking an average run of 316.11 mph at the Bonneville salt flats. This record wasn’t official, which sent the team back to the location for another run, which gives us our current top speed. This car uses a 5.9-liter twin-turbocharged V8 engine that produces 1,350 horsepower when using 91 octane fuel. That figure is bumped to 1,750 horses when E85 is in the tank.

These are the seven fastest cars in the world right now. Will there be any car that can take down some of these models in the near future?
