Actor ZAC EFRON showed off his love of cars recently when he took to the road
at the Infineon Raceway in California.
 
The High School Musical star hit the racetrack in Sonoma as part of the Audi
Driving Experience.
 
He raced for four hours in a $118,000 (£59,000) Audi R8 car.
 
And Efron admits he thoroughly enjoyed the adrenaline rush.
 
He tells People.com, "I've never been on a race track before, never once -
and we were going pretty fast by the end."
