Two-time World Superbike champion Troy Corser added a further string to his bow this week after enjoying an outing in a Formula 1 car as part of a 'machine swap' during a special BMW initiated Fan Day at the Nurburgring.

With BMW's maiden season in the World Superbike Championship ensuring two-wheel machines were a feature of the annual event for the first time, Corser jumped into the cockpit of the BMW Sauber F1.08 that took Robert Kubica to Canadian Grand Prix victory last season, while Nick Heidfeld took up Corser's mount, the S1000RR.

Corser is no stranger to action on four wheels, the Australian having tested a Ford Focus World Rally car as recently as 2008.

However, the 37-year-old was in awe at the sheer power and braking ability of the 700bhp machine underneath him.

"It was just awesome! The car feels so balanced and the brakes are fantastic, the tyres have unbelievable grip and the steering is very direct but still has a lot of feeling. I can't believe how hard and late you can brake.

"I know I was braking too early and I really would like to have a day or two with the car to really see what I can do with it. I'd like to thank everybody involved in giving me this opportunity - and I hope I can do it again."

Heidfeld, meanwhile, was also impressed by BMW's first Superbike, claiming that he would like to get another chance to ride it.

"It was a sensational experience - thank you to everyone! I already had lots of fun practising on the street bike in the morning, and managed to score the first scrapes into the knee area of my racing suit. That was inevitable. Of course I wanted to touch the ground while cornering on the racing machine as well, and I came up trumps there too.

"I had expected the Superbike to be a huge leap over the production version, a bit like series cars and racers, but I was surprised in the end. The difference is huge. On the one hand the Superbike is more aggressive, builds up more grip and has the superior brakes, but on the other hand it is easier to ride because you can control it so well. The handling is very precise.

"Obviously I'm still miles from the limit with the superbike; I would love to have done a lot more laps."
