Red Bull Racing's David Coulthard will be heading out early to North America prior to the Canadian Grand Prix to pay a visit to Red Bull's NASCAR team in the United States.

The weekend before the F1 race in Montreal sees the NASCAR boys racing at Dover in Delaware, on a track known as the Monster Mile.

Coulthard will be a guest of the NASCAR Red Bull Racing Team, which is now in its second year of competition, racing Toyota Camrys driven by Brian Vickers and AJ Allmendinger.

"I'm interested in all sorts of racing, but hardly ever get a chance to see anything other than Formula 1," said the Scotsman. "So when Red Bull came up with the idea of shooting a promo film around their NASCAR operation on the week before the Canadian GP, it seemed like a great opportunity to go and see why this form of racing is so popular in the States."

Coulthard will arrive in time for race day, Sunday 1st June, when he will get a chance to sit in the race car as well as sitting in on the team's pre-race engineering briefing before watching the 'Best Buy 400.'

The race is so called due to sponsor backing and because it consists of 400 laps around the one-mile track - over twice the distance of the following weekend's Formula 1 Grand Prix in Canada.
