First of all I didn't include prototypes, dragsters or even jet powered cars.
For now the fastest car is Hennessey Venom F5.
Claimed top speed is atonishing 301 mph!
The top speed was achieved with brand new 2,950-pound carbon fiber chassis and gorgeous 7.4l bi-turbo V8 that makes 1,600 hp.
Car can go from 0 to 249 to 0 in about 30 seconds.
Hennessey has yet to confirm the top speed so the worlds official fastest car is still Koenigsegg Agera RS.
