Fuel Economy & Alternative Fuels

GM has the most models with EPA-estimated 30 mpg or higher highway* fuel economy.

Thanks to a committed research program, GM utilizes numerous technologies designed to improve fuel efficiency without sacrificing smoothness or power output. Active Fuel Management, Clean Diesel Technology, and Spark Ignition Direct Injection can all be found on select GM vehicles available today.

GM has over 3 million FlexFuel vehicles on the road today.

E85 ethanol vehicles can run on either gasoline or E85 — a blend of 85% ethanol and 15% gasoline — or a combination of both. E85 ethanol fuel is a cleaner-burning, mostly renewable fuel source made from mostly U.S.-grown corn and biomaterial, such as switchgrass and willow.

GM will release an average of one new hybrid model every three months for the next four years.

Starting with the 2008 Saturn VUE Green Line and the industry's first full-size hybrid SUVs, the 2008 Chevrolet Tahoe Hybrid and 2008 GMC Yukon Hybrid, we'll be well on our way to fulfilling our commitment to provide one of the broadest portfolios of hybrid vehicles in the industry.

Imagine a 40-mile or less daily commute without using a drop of gas.

GM's innovative E-Flex Propulsion System uses stored electricity for short trips, while utilizing a variety of fuel sources to create electricity on-board.

The best emissions policy is a ZERO emissions policy.

That's why GM is breaking new ground on fuel cell technology that uses hydrogen to create electricity, the only byproduct being water. The Chevy Equinox Fuel Cell is powered by GM's fourth generation hydrogen fuel cell system — our most advanced fuel cell propulsion system to date.
