There has been some speculation that BMW was going to withdraw from the World Touring Car Championship with its re-introduction into the DTM. However this Autosport report that BMW is readying a new generation of engines for teams running BMW indicates otherwise. That means that, at least, we ‘ll see BMW power private teams in the WTCC for 2011. In fact with 2011 the start of the new engine specifications we ‘d be shocked to see BMW develop the new engine for 2011 (where the bulk of the money is spent) and not simply support the teams in 2012 and beyond when they enter DTM.
Now the question of BMW staying in WTCC as a factory team is a different story and one that cannot be answered at this time.
