Today I'm going to talk about the fastest cars in the world. There is the official fastest car in the world, the Bugatti Veyron Super Sport, and the unofficial fastest car in the world, the Hennessey Venom GT. Firstly I am going to talk about the Bugatti. It has an 8.0 litre W16 engine producing 1,200bhp and costs an astonishing €1.9 million. Its top speed is 267.8mph / 430.9km/h. The reason it is officially the fastest is you have to drive both ways on the track it is being tested on and take the average. What I am going to look at is how long it would take the Bugatti to drive the entire length of the equator at top speed. The circumference of the earth at the equator is 24,902 miles / 40,075 km. this means it would take the Bugatti only 93 hours to travel the entire equator. At its top speed, the Veyron Super Sports engine consumes 45,000 litres of air a minute so on its journey around the equator it would consume a total of 251,100,000 litres of air! It also only doe 11.6 mpg so it would use 2,146 gallons of petrol on its journey.
The Hennessey Venom GT hit 270.49mph / 435.3km/h. It is not official however as it did not go both ways on the track it was being tested on. It has a 7.0 litre twin turbo V8 engine which can produce 1,244bhp and costs €792,041. The Venom GT would take 91 hours to travel the length of the equator, a whole 2 hours less then the Veyron. It does 15.9 mpg and would use 1566 gallons of petrol, a massive 580 gallons of fuel less then the Veyron.
