A1GP champion Carroll returns to British GT in Balfe Audi

Carroll, whose last British GT appearance came in 2016 when he was third at Silverstone in a Ferrari entered by FF Corse and Fox Motorsport, raced the Audi alongside Balfe in last year's International GT Open series that uses Michelin tyres.

The car will run on Pirellis in British GT, a series Balfe last contested as a driver in 2019 when he and Rob Bell finished five points shy of the title despite missing the Oulton double-header due to teething problems with their new McLaren 720S GT3.

Carroll first came to prominence by winning the 2002 British Formula 3 national class and finished second to Nelson Piquet Jr in 2004.

He scored five GP2 wins between 2005 and 2007, and made two IndyCar appearances in 2010 after securing the final A1GP title in 2008-09.

For the Northern Irishman, whose sole British GT win came at Oulton Park in 2016 with Barwell Motorsport, it will be a first full season in the championship after two part-seasons for FF Corse alongside Garry Eastwood in 2014-15.

“We're going to give everything we've got and I'm looking forward to getting stuck into the full season,” the NIO Formula E reserve driver said. "Hopefully we can win a few races and score podiums along the way, and we'll be in the hunt for the championship.”

Balfe said: “Adam and I get on well and make a really good partnership. We really gelled last year and I’m sure we can take that forward. British GT is a true
