Robbie Kerr will drive for Great Britain when the A1 GP series begins at Brands Hatch on 25 September.
Kerr will drive at Brands and Lausitz in Germany
The 2002 British F3 champion has been given the first two races, with Alex Lloyd also in line to race for Team GB.
Billed as a World Cup of motorsport, A1 GP pits nations against each other in identical cars.
"It's a brilliant opportunity for me." said Kerr. "People will learn who I am and that makes it easier to go to teams or sponsors next season."
GB team principal John Surtees said: "Robbie drives very well but suffers from the fact that he has not been able to put a full racing programme in place due to funding issues.
"He's had to knock the rusty edges off his driving and he is at a slight disadvantage compared to some of his rivals in not having raced regularly in the past couple of years.
"But he is a very competent driver and first and foremost our responsibility is to succeed, especially as we are flying the flag for the country."
Despite recent career setbacks, Kerr, 25, is still hoping to earn a chance in Formula One.
"You have to aim for the top and in motorsport, the top is Formula One so I am still aiming for that - I have to."
