Imagine a car that moves so quickly, that if you blink at the wrong time, you'd miss it driving past you.
Well a group of students in Bristol are hoping you won't have to imagine it for much longer, as they're planning to make the world's fastest car.
It's going to be called the Bloodhound, and the students want it to break the record for the fastest car ever.
The current record is an amazing 763 miles per hour, but the students reckon the Bloodhound could drive at 1,000mph!
At the moment the car is just a computer model, lots of technical drawings and a model made from plasterboard.
But by the year 2010 the students plan to have built a working Bloodhound car that they can start testing.
Fighter plane engine
So how do you make a car drive faster than 1,000 miles per hour? Use a jet engine from a fighter plane.
Thankfully the man who will be driving the car knows a bit about travelling at that speed, as he's RAF pilot Andy Green.
And Wing Commander Green doesn't just fly planes, he was also behind the wheel when a car called Thrust set the current record.
