Marcos Ambrose makes his Daytona Prototype Sportscar debut in the Montreal 200 at the Circuit Gilles Villeneuve in Montreal, Canada this weekend.

It comes a week after Ambrose’s finest result of his career with third place in the Sharpie 500 at Bristol Motor Speedway in the NASCAR Sprint Cup Series.

This weekend’s 10th race in the 2009 Grand-Am Rolex Sportscar Series will see Ambrose and fellow NASCAR Sprint Cup star Carl Edwards  drive the #77 Dallara Daytona prototype of Doran Racing, with backing from Aflac, iRacing.com, Subway and Au wines.

“This is my first time in the series and it should be exciting. We tested at Virginia International Raceway (VIR) and everyone on the team is really cool and I know it’s going to be a lot of fun., said Edwards”

Ambrose and Edwards tested the car at Virginia International Raceway (VIR) last week, setting respectable lap times, learning the car and even practicing driver changes in a serious attempt at a race victory from the pair, despite their relative inexperience in 500-horsepower Grand-Am prototype machines.

“The Montreal Grand-Am race is going to be something different for both of us and if the VIR test is any indication, we can head there and be competitive,” said Ambrose.

“I have to really thank Kevin Doran and his team for this whole Grand-Am deal. I really want to repay their faith with a good run.”

Ambrose and Edwards finished second and third respectively in the Sprint Cup race at the Watkins Glen road course two weeks ago and both have previous top 10s at the 2.71-mile Circuit Gilles Villeneuve road course in Nationwide Series competition.

Kevin Doran’s #77 Daytona Prototype has competed in all nine rounds to date in the 2009 Grand-Am Rolex Series, with a best finish of fifth at Virginia International Raceway in April, with Memo Gidley and Brad Jaeger at the wheel.

Ambrose has made one previous Grand-Am start, in the GT class at the 2005 Daytona 24 Hour in a Porsche GT3 Cup car with fellow Australians Paul Morris, Craig Baird and John Teulen.
