Corvette Racing Program Manager Doug Fehan announced last night that GM Vehicle Line Executive Tom Wallace will retire from the company effective November 1st.

The news, delivered at a Petersen Museum event honoring Corvette Racing history, came as a shock to those of us involved in the hobby, who have come to appreciate Wallace's keen grasp of performance-car culture and obvious passion for the marque.

While no reasons were given for the move, Wallace's departure could be related to uncertainty surrounding the timeline for the seventh-generation Corvette. The car--originally slated for a 2012 model-year release--has reportedly been pushed back by at least two years, a span to which Wallace may have been unwilling to commit.
