Martin Tomczyk will defend his DTM title with BMW in 2012 after confirming his switch to the series returnee.
Tomczyk, 29, won this year's title with the Phoenix Audi squad, but revealed on Monday that he was quitting the manufacturer in search of a "new challenge." He has now been announced as a BMW driver alongside Bruno Spengler, Andy Priaulx and Augusto Farfus, much to the delight of BMW Motorsport director Jens Marquardt.
"Our squad of drivers is gradually firming up," Marquardt said. "With Martin Tomczyk we are proud to have gained an absolute top-notch driver for our DTM involvement.
"Despite being fairly young in the touring car context, he is one of the most experienced DTM drivers around: he's consistently fast, of impeccable character and an out-and-out winner. In 2011 he was the first driver ever to win the DTM championship in an older-spec car. We will do everything we can to consolidate this success with him in the future.
"Our target is to become competitive as quickly as possible, and from that point of view we see Martin as an extremely important asset."
BMW has yet to announce which of its three teams – Schnitzer, RBM or RMG – Tomczyk will race for next year.
