MotoGP mega star Marc Marquez was awarded an F1 test today by Red Bull, the 25-year-old taming an older V8-powered RB8 chassis around the Red Bull Ring.
Nine-time Grand Prix winner Mark Webber was on hand to dispense some advice to the Honda rider, along with Red Bull motorsport boss Helmut Marko.
"Today, a full smile, all day! It was a great experience," Marquez said.
"It was incredible to drive a Formula 1 car, because it's my first experience with a car at a track – I never drove before. I drove a Formula 3 car, but only two laps in Motegi.
"Yesterday I was very, very nervous, this morning too – difficult to sleep, even more than in a race weekend! But step by step we just tried to find a way, to enjoy, and it was really good.
"They tell me [I was] not bad [to begin with], but I was so far [away from the pace], but then step by step I understand the things, and around these legends everything is easier.
"It is a day that will be always in my mind."
