Car manufacturers are racing each other not only to decrease fuel consumption but also CO2 Emission of the vehicles while improving their technologies.
Here we list fastest cars in the world. Please note that these cars are production cars, that means they are stock and not modified. In the list all sports cars are listed and sorted by top speed. Bugatti, Koenigsegg and Pagani are well known for manufacturing super sport cars. Most of the production cars’ top speed is limited, that means it can be easily exceeded by applying some modification.
Maximum speed of a car is mostly about engine power and engine size. That is followed up by the maximum torque output of the super sport automobile.
If you ask what is the fastest car in the world in 2017, the answer is Bugatti Chiron by 420 km/h. This makes more or less 260 miles per hour.
