There are certain measures car manufacturers must take to make a car as fast as it could be. The most obvious one is power, and the fastest cars in history have a power margin of 900 hp or more. Of course, there are other aspects to look at like downforce, aerodynamics, grip and durability which contribute to how fast the car will go and what speed limit it will hit. The most famous supercars or hypercars to break the speed of light is the McLaren F1, Bugatti Veyron, SSC Aero Ultimate and Porsche 959.
This list is for the fastest cars according to the top speed and not the 0-100 km/h sprint time. All speed records have been done by the car manufacturers with their respective hypercars. The speed records are confirmed by World Record organizations such as Guinness World Record and some are claimed by the manufacturers.
- Hennessey Venom GT
American based supercar maker which also doubles as a tuning company for car models made by Ford, Chevrolet and others, made a supercar specifically to break the Veyron’s spirit of speed. It has a 7.0 litre twin-turbocharged LS7 V8 engine producing 1244 hp (928 kW) and it was claimed to do 0-300 km/h in 13.63 seconds. The top speed was recorded at 265.7 mph (427.6 km/h) but unfortunately, it was ruled out because it did not meet certain requirements to be deemed the fastest. The Spyder version managed to hit the same top speed which was accepted and it was driven by Brian Smith.
- Koenigsegg Agera RS
The Agera RS was one of the fastest cars in the world when it set a speed record of 278 mph (447 km/h) but that was not the sole purpose of it. It managed to do 0-400-0 km/h in just 36.44 seconds beating the Bugatti Chiron’s time by 5.56 seconds. The record was set by Koenigsegg’s test driver Niklas Lilja in October 2017. The engine under the hood or should I say the rear is a 5.0 litre twin-turbocharged V8 with a power output of 1160 hp (865 kW) and 1100 Nm of torque. Travelling at 250 km/h, the Agera RS generates 250 kg of downforce ensuring that it is planted to the ground.
- SSC Tuatara
We thought that we would never see this hypercar in production because it was revealed as a concept car back in 2011 and ever since we never got to see progress on the project until 2014 when it was announced to be put into production. It has a 5.9 litre V8 twin-turbo engine producing 1350 hp (1007 kW) but with E85 fuel, the power is boosted to 1750 hp (1305 kW). The top speed is said to be at around 300 mph (482.8 km/h) thanks to some lightness measures taken by using a carbon fibre monocoque chassis and bringing the curb weight to 1247 kg. The Tuatara serves as a predecessor for the SSC Ultimate Aero.
- Hennessey Venom F5
The successor of the Venom GT had to be produced in 24 units in order to qualify to set a speed record. Although it hasn’t done that yet, Hennessey has claimed it can break the 300-mph barrier by 301 mph (484 km/h) and can do 0-400 km/h in under 20 seconds. The engine was initially a 7.4 litre twin-turbocharged V8 but later downsized to a 6.6 litre LS based iron block engine. It produces 1817 hp (1355 kW) and 1617 Nm of torque with all the power going to the rear wheels and shifted on either a 6-Speed Manual or 7 Speed-Auto.
- Bugatti Chiron Super Sport 300 plus
Bugatti specifically built this car to break the world record for the fastest car in the world and it did. Andy Wallace managed to do 304.773 mph on Volkswagen’s Ehra-Leissien test track in Germany and a video was upload on YouTube and the car that was used to record that video was a normal Bugatti Chiron fitted with a camera rig. It is powered by an 8.0 litre quad-turbocharged W16 producing an astonishing 1578 hp (1 177 kW) with a curb weight of 1996 kg which is Bugatti’s curse but they still managed to make it so fast. Only 30 units were made and all were sold out.
