With the energy bill now pending in Congress, many have questioned the viability of the gasoline fueled-internal combustion engine in cars, citing incremental mileage gains of the past few years as proof the technology has reached its zenith.

But GM doesn’t believe the gas engine is dead. It will absolutely remain a significant part of our Advanced Propulsion Technology Strategy for the foreseeable future. As Chairman and CEO Rick Wagoner said on Dec. 3, “The new CAFE standards pose a significant technical and economic challenge to the industry. It’s a challenge that GM is prepared to put forth its best effort to meet with an array of engineering, research and development resources.”
