GM's 3.9L V-6 Family Grows with E85-Capable and Fuel-Saving Active Fuel Management Versions

Chicago, IL. (2006-06-19) - Today at the Midwest Automotive Media Association meeting Ed Peper, General Manager, Chevrolet, announced General Motor's first V-6 application of fuel-saving Active Fuel Management™ on the 3.9L V-6 offered in the 2007 Chevy Impala, and E85 ethanol fuel capability on the 3.9L V-6 offered in the '07 Chevy Uplander.
"The application of Active Fuel Management™ (AFM) and E85 ethanol offers customers more choices when it comes to selecting efficient, fuel-conscious vehicles," said Peper. "E85 fuel reduces the need for petroleum and helps reduce greenhouse gas emissions, while AFM offers improved fuel economy over comparable, non-AFM engines."

Preliminary testing of the 2007 Chevy Impala equipped with the 3.9L V-6 with AFM indicates an estimated 20 mpg in the city and 29 mpg on the highway - improvements of approximately 5.5 percent and 7.5 percent, respectively.

Active Fuel Management enables the engine to automatically operate on half of the engine's cylinders under light load conditions, improving efficiency by reducing fuel consumption when the cylinders are deactivated. GM offers this fuel-saving technology in 11 vehicles for 2007, including trucks and SUVs - more than any other automaker. The Impala is GM's first V-6 application of AFM in North America.

The E85-capable version of the 3.9L engine enables customers of the Uplander vehicles to use a renewable, domestically produced fuel that produces fewer emissions. E85 is made of 85 percent ethanol and 15 percent gasoline. GM vehicles with E85 capability can run on 100 percent gasoline or on E85 ethanol fuel or any combination of the two.

"GM has nearly 2 million flex-fuel vehicles on North American roads, and will offer 14 E85-compatible vehicles in 2007," said Peper.

The 3.9L V-6 is part of GM's family of sophisticated, high-value V-6 engines. In addition to AFM and E85 capability, it features variable valve timing (VVT) - a first for cam-in-block V-6 engines (recognized by Popular Mechanics with a "Breakthrough Technology Award" in 2005.) Along with optimizing performance and economy, the VVT operation helps the engine maintain an adequate torque load to maximize the benefits of AFM's fuel-saving mode.
