POWER TRAIN AT GM
Fuel efficiency gains and emissions reductions are the primary benefits that General Motors wants to deliver with its forthcoming product releases. "We'll have nine new or significantly revised engines and transmissions for North America in the 2006 model year," said GM Powertrain Group Vice President Tom Stephens. Among the products slated to debut in 2006: new variants in the Gen IV small-block V8 engine family, six-speed automatic transmissions, and the Belt Alternator Starter (BAS) hybrid system.
