But the Veyron is like a Toyota Prius compared to the planned world land speed record car "Bloodhound":
Bloodhound's Falcon rocket will be the biggest hybrid (solid fuel propellant, liquid oxidiser) booster ever produced in the UK. Such is its scale, it will need a Formula One engine supplied by the legendary Cosworth group just to pump the oxidiser through the motor.
The Cosworth-Ford engine was the phenomenally successful powerplant that dominated Formula One racing starting in the late 1960's. It was a conventional 3-liter, four-cam, 32-valve V-8 that initially produced about 375-bhp. During its competition years the output was tweaked to 500-bhp.
And now it's going to be a fuel pump.
