A British team is developing this pencil shaped car which can travel more than 1000 miles in an hour. Check out the link below for the complete information.
Actually the speed of the car is 1000 Miles in One Hour. And it goes from 0 to 1000 in just 45 seconds..
BTW, this is a Jet Engine car, which can run only on vast salt deserts. It is more of a rocket running horizontally than a road car, built mainly to create new aerodynamic designs and also to create records.
