The bloodhound is a unique vehicle - it was created solely to break a world-record.
To get to 1000mph, it takes a lot of power:
A jet engine to get it up and running, normally on a typhoon fighter
A racing car engine borrowed from Formula 1 to kickstart the rocket, which takes the acceleration beyond 2G.
Travelling faster than the speed of sound means staying on the ground is a challenge in itself.
It has taken the team more than five years to settle on the vehicle's bullet shape.
At top speed, the wheels will rotate 174 times a second and expand during the run.
It will be driven at the Hakskeen Pan in the Mier area of the Northern Cape, South Africa.
16,000 tonnes of stone across a massive area have been removed and a track 12 miles (19km) long and two miles (3.2km) wide has been cleared, for the supersonic car.
The Bloodhound test action will be streamed live on www.Bloodhoundssc.com and via YouTube and Facebook from 12:45pm BST
