BMWBMW will withdraw from either sports car racing or the World Touring Car Championship if it presses ahead with its proposed DTM entry in 2012, AUTOSPORT reports.

The manufacturer's motorsport boss Mario Theissen has admitted that it could not sustain three works programs and it will have to decide its priorities.

BMW still has not committed to the WTCC as a factory entry beyond the end of this season, while its GT project is so far confirmed to the end of 2011. It is pressing ahead with development of the 1.6-liter turbocharged engine that will form the basis of the new Super 2000 regulations in touring cars and rallying from next year, but Theissen denied this is a sign that it will continue in the WTCC. The unit – which will also power the Mini WRC car – was conceived as a customer engine for BMW touring car teams around the world.

The marque has stepped up its GT activity by committing to all three rounds of the inaugural Le Mans Intercontinental Cup this season, while Schnitzer will run one M3 at Silverstone and Zhuhai, and Rahal Letterman one at Petit Le Mans.
