Guernsey driver Andy Priaulx says his move to the DTM championship next season will be the "biggest" challenge of his career.
The triple World Touring Car champion has signed for BMW for next year's German touring car championship.
"It's probably the biggest thing I've done in my motorsport career so I'm really looking forward to the challenge," Priaulx told BBC Guernsey.
Priaulx will partner Brazilian driver Augusto Farfus next season.
"It's a very exciting programme for BMW and it's really gaining momentum, and that's obviously where my future lies for next year and beyond," Priaulx added.
