It's the rev part of the long clip "Aurelie and Isa - Hard Rev and Hard Drive"...
Isa is trashing hard engine and asks to Aurelie she wants to do the same. Aurelie fllors the gas with her left foot, and then, she takes the wheel and continue to floors the gas pedal under instructions of Isa. Isa put her left foot on gas pedal to help Aurelie to light on the temperature light : TWO feet on gas pedal. Isa goes back to the driver seat, and teachs to Aurelie how to use the clutch, very nice clutch, and little tyres spinning.
