GM Powertrain is investing about $US10 million to produce performance engines at a new manufacturing site located in Wixom, Michigan, to be called the GM Powertrain Performance Build Centre.

GM vice president of engineering operations, Ed Koerner, said: " A small but very passionate group of customers wants and demands vehicles with uncompromising levels of performance. The new Performance Build Centre is dedicated to satisfying these customers."

Site preparations began in spring 2003, with start of production planned for summer 2005.
