According to Tom Stephens, GM’s vice chairman of global product operations the Two Mode hybrid powertrain developed by the American manufacturer and used only on trucks, will soon migrate to rear-drive cars in the next-generation and the best candidate will be Cadillac.

GM is already developing an engine that is 25 percent smaller and 20 percent more powerful than the motor used in today’s Two Mode hybrid full-sized trucks. “The new motor will be lighter. It will be more affordable,” said Stephens. The new motor will debut in 2013 in GM’s next-generation, full-sized trucks and due to the fact that is smaller GM will also use these motors in cars. Cadillac ATS, a rear-drive Cadillac smaller than the CTS is expected to carry GM’s next-generation Two Mode hybrid system as well as the next-generation CTS, which will debut in 2012.
