Guess who's driving an F1 car today?

Six-time MotoGP world champion Marc Marquez is adding another pair of wheels to his expertise today, the Spaniard getting his long awaited run in a Red Bull Racing F1 car.

Marquez will lap the Red Bull Ring in Austria onboard an old-spec V8-powered machine, emulating his great rival Valentino Rossi who enjoyed a few tests with Ferrari over a decade ago.

The 25-year-old motorcycle prodigy posted on twitter a snippet of himself heading out on to the track this morning.
