2007 Truck Engines & Transmissions

E85 FlexFuel = E85 flexible fuel vehicles are designed to be able to run on E85 ethanol, gasoline, or any blend of both fuels. The engine control module in a flexible fuel vehicle helps to identify what fuel or blend of fuels is running through a vehicle's system. Based on the data provided, the system then makes adjustments accordingly. In 2007, GM will offer 17 E85-compatible models totaling about 400,000 vehicles, compared to nine models in 2006. GM's E85 FlexFuel models operate on a mixture of up to 85 percent ethanol and 15 percent gasoline. A GM Flex Fuel vehicle can run on 100 percent gasoline, E85 ethanol or any combination of the two. The company has already more than 2 million flex-fuel models on North American roads.

Horse Power and Torque SAE Certified Power = A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005. This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing.  GM leads the industry in applying the new voluntary SAE Certification process, and will certify horsepower and torque for all new engines under independent review. For the 2007 model year, GM certified an additional 24 engines, totaling 102 applications.
