GM Plans Engine Variations

General Motors’ group vice president in charge of powertrain operations says the company
plans to roll out 19 new engine and transmission variations for the 2007 model year.

These
include a hybrid version of the Saturn Vue and also includes a new 3.9-liter V-6 with a
fuel system that shuts down three cylinders on the highway to save gas, as well as
six-speed transmissions that will improve fuel economy and performance.

For 2007, GM also
will offer 14 E85-compatible models that run on a mixture of up to 85 percent ethanol and
15 percent gasoline.The vehicles can run on 100 percent gasoline, E85 ethanol or any
combination of the two. The Gen IV small-block engines — with active fuel management,
cylinder deactivation, variable valve timing and E85 capability — will be some of the most
powerful and efficient V-8 engines available for light trucks.
