Hybrids

A Wide Variety of GM Hybrids... One for Every Need.

Driving Energy Independence

At GM, we're committed to leading the way in hybrid development as one of our many roads to a less petroleum-dependent future. We're building hybrid cars, trucks, SUVs, and crossovers for work, for families and for first-time drivers. In 2009 GM intends to offer 8 hybrid models, one of the industry's most extensive lineups. We're proud to be a leader towards greater energy-independence. These vehicles include: 2009 Cadillac Escalade Hybrid SUV (limited availability), 2009 Chevy Tahoe Hybrid SUV (available at participating dealers only), 2009 Chevy Silverado Hybrid Truck (limited availability), 2009 GMC Sierra Hybrid Truck (limited availability), 2009 GMC Yukon Hybrid SUV (available at participating dealers only), 2009 Chevy Malibu Hybrid Car (available at participating dealers only), 2009 Saturn VUE Hybrid SUV (limited availability), 2009 Saturn AURA Hybrid Car (limited availability in select markets. Select markets include the following cities: Los Angeles, Seattle, San Francisco, Chicago, New York, Philadelphia, Washington D.C., Phoenix, Boston, Sacramento). They offer increased fuel efficiency and economy over their conventional counterparts. Most have received IRS certification as being qualified for a hybrid tax credit according to the U.S. Department of the Treasury.

Powerfully-efficient: GM Two-Mode Hybrid

GM's Two-Mode Hybrid system operates on engine power, electric power, or a combination of both. A sophisticated control module determines the amount of power required at a given moment and seamlessly selects the appropriate operating mode. The system uses regenerative braking to recapture energy that normally escapes as heat and stores it in an advanced battery pack so it can be used at a later time.

GM Two-Mode Hybrid vehicles include:

Mode 1: Low Speeds

In Hybrid Mode 1, used mainly at low speeds with light loads, GM Two-Mode hybrids can operate using electric power alone, supplied by the onboard 300-volt battery. Mode 1 can also use just engine power or a combination of electric and engine power. Fuel consumption is reduced in stop-and-go traffic as the engine operates on electric power alone when your vehicle is stopped, seamlessly restarting when you accelerate.

Mode 2: Highway Speeds

In Hybrid Mode 2, used as vehicle demands increase in both city and highway driving, electric power supplements the engine to improve fuel economy. Fuel consumption is reduced by providing some of the needed power from the battery allowing the 6L V8 engine (on the Chevy Tahoe, GMC Yukon and Cadillac Escalade hybrids) to run more efficiently. GM's Active Fuel Management system also senses when you don't need all eight cylinders and smartly adjusts to run on four, giving you even better fuel economy.

Economic Value: GM Hybrid System

The GM Hybrid System delivers a 10-20% improvement in fuel economy at an exceptional value. How? By employing a 36-volt nickel metal hydride battery paired with a 3kW electric motor working in conjunction with a 4-cylinder engine and automatic transmission. The system saves fuel by shutting the engine off whenever possible (typically at idle and during deceleration), capturing energy through regenerative braking and optimizing engine and transmission operation.

Fuel-Efficient Power

When your vehicle comes to a stop, the gas engine is shut off and your vehicle's accessories (stereo, lights, etc.) are powered by the hybrid battery, saving you fuel. What's more, it makes sure that when the light turns green and you take you foot off the brake pedal, the gas engine seamlessly re-starts and you have power on demand. The system also improves performance with electric assist during acceleration. During vehicle deceleration, gas to the engine is cut off, again saving you fuel.

Regenerative Braking

The GM Hybrid System's regenerative braking feature captures some of the energy naturally lost during vehicle braking and coasting. It returns that energy to the 36-volt nickel metal hydride battery for future use powering the vehicle. Regenerative braking helps boost fuel efficiency by charging the battery.

The Challenge: Save as Much Fuel as Possible

So how did we go about starting to meet the challenge of saving fuel and fuel cost? Apply hybrid technology first to high-volume, high-fuel-consuming vehicles. It's a challenge tailor-made for a leader like GM. We've delivered more than 1,000 GM-Allison hybrid-powered buses to more than 80 cities across the U.S. and Canada. And orders in-process bring that total to nearly 1,800. These buses will save an estimated 1.2 million gallons of diesel fuel per year − enough fuel to fill 150 tanker trucks. Then we took the next step...

Powering Change: Taking it to the Streets

We've applied the proven Two-Mode hybrid technology from the GM-Allison hybrid buses to class-leading hybrid pickups and SUVs like the award-winning Chevy Tahoe, GMC Yukon, and pickups like the Chevy Silverado and GMC Sierra. Going even further, we've introduced hybrid options in sedans and crossovers like the award-winning Malibu and the Saturn VUE. And there's much more to come. No matter which GM hybrid you choose, you can rest assured that it will meet your needs and help ease your fuel costs.

Next-Generation GM Hybrid System

With up to 20% fuel savings, the next-generation GM Hybrid system is an affordable hybrid option that will be nearly three times as powerful as our current GM Hybrid system. The next-generation system is based on a lighter, more powerful lithium-ion battery, paired with a new motor generator to provide more electric assist for longer periods of time, for better fuel efficiency and lower CO2 emissions. To be introduced in North America in 2010.

Rewarding Innovation

We're proud to say that GM hybrids and the technology that powers them have earned honors and accolades from respected industry groups and publications.
