Time, resources, and the brightest minds — GM is continually assessing our vehicles' environmental impact and taking steps to reduce it. We're committed to improving the fuel economy of all of our vehicles while still providing the performance and utility that customers need and want.
We're pursuing several options to best meet the varied needs of customers around the world — from gasoline, diesel and biofuels to electrically-driven vehicles such as hybrids, electric vehicles with an extended range and hydrogen fuel cell vehicles.
GM continues to make fuel economy and emissions improvements to our engines with technological advances. Features such as Active Fuel Management, 6-speed transmissions, variable valve timing, and direct injection help deliver optimal fuel economy without compromising your drive.
Xtra Fuel Economy (XFE) models offer improved fuel economy over non-XFE models. Mechanical, aerodynamic and mass-reducing enhancements make it possible.
For the 2010 model year, GM has 13 vehicle models that offer at least 30 mpg hwy or better. (EPA estimate):
The 2010 GMC Terrain and Chevrolet Equinox offer 32 mpg highway (EPA estimate), the highest highway fuel economy for their segment.1
The 2010 GMC Sierra and Chevrolet Silverado full-size pickup trucks offer the best fuel economy of any full-size pickup in America. Better than Ford F-150, Dodge Ram and Toyota Tundra.2
GM offers powertrain options in most of our products. For improved fuel efficiency, consider a smaller engine. Downsizing your engine can reduce your operating costs.
Engine choices include:
GM believes promoting the use of biofuels, specifically E85 ethanol (85 percent ethanol and 15 percent gasoline) is the most significant near-term solution to offset rising vehicle energy demands and reduce greenhouse gas emissions. Sustainable biofuels made from non-grain sources could offset up to 35 percent of future vehicle energy demand by 2030.
GM is the global leader in producing flexible-fuel vehicles,3 and has committed to making more than half of its vehicle production FlexFuel-capable by 2012. For the 2010 model year in the U.S., GM offers 18 E85-capable FlexFuel models.

By mid-2010, all Duramax 6.6L V8 turbo engines will be B20 biodiesel-capable. B20 fuel is 20 percent biodiesel and 80 percent conventional diesel, which helps lower carbon dioxide emissions and dependence on petroleum.
GM's new Duramax 6.6L turbo diesel engine has been substantially revised to include B20 capability, as well as meet strict new emissions standards. The new Duramax will power the redesigned 2011 Chevy Silverado and GMC Sierra heavy-duty pickups (coming Summer 2010), and will also be available on the 2010 interim and 2011 Chevrolet Express and GMC Savana full-size vans.

Featuring GM's exclusive two-mode hybrid technology, our lineup of hybrid vehicles offers the power and capability you expect from a truck or SUV, while offering fuel economy you never imagined.
Chevrolet Tahoe Hybrid, GMC Yukon Hybrid, and GMC Yukon Denali Hybrid:
Equipped with GM's hybrid technology, these vehicles deliver up to a 50% improvement in city fuel economy (and 30% overall for both city and highway) over their non-hybrid models.4
Cadillac Escalade Hybrid:
Equipped with GM's hybrid technology, Escalade Hybrid delivers up to a 40% improvement in city fuel economy when compared to the non-hybrid Escalade models. (Estimated 25% improvement in combined fuel economy.)5
Chevrolet Silverado Hybrid 1500 and GMC Sierra Hybrid 1500
(crew cab versions):
The Silverado and Sierra pickups are the only hybrid pickup trucks on the market. They offer better city fuel economy than a standard six-cylinder Toyota Camry or Honda Accord.6 Knowing that, it should come as no surprise that America's first two-mode hybrid full-size pickup offers up to 40% better city fuel economy than Toyota Tundra and Ford F-150, and up to 50% better than Dodge Ram.7
The Chevrolet VOLT is an electric vehicle with extended-range capability. Plug it in, let it charge overnight, and it runs on pure electric charge for up to 40 miles — gas- and emissions-free.8
After that, the VOLT keeps going, even if you can't plug it in. Thanks to a range-extending gas generator, it produces enough energy to power the VOLT for hundreds of miles. It's more than a new car — it's the future of transportation.

GM is a leader in hydrogen fuel cell technology and we have demonstrated our fuel cell vehicles around the world in places like Washington, D.C., Los Angeles, Tokyo, Berlin, Shanghai and Korea.
In fact, in October 2007, GM activated Project Driveway — the largest market test of fuel cell vehicles in the world. Project Driveway entails the loan of Chevrolet Equinox Fuel Cell vehicles to everyday drivers, celebrities and other dignitaries to gauge interest, consumer reaction, and vehicle performance in the U.S.
Vehicle deliveries to program participants began in early 2008. To date, the fleet of vehicles has driven more than total of 1,000,000 miles.

GM joined the United States Climate Action Partnership (USCAP) in May 2007. GM was the first automaker to support this partnership of industry and environmental organizations working to address climate change through advanced technology. USCAP has issued a set of principles and recommendations toward slowing, stopping and reversing the growth of greenhouse gas emissions.
GM wants to be a part of solutions that work and it's an approach we share with USCAP and its members.
