Tulsa becomes 33rd City to Opt for GM's Fuel-Saving Technology

March 29, 2006

TULSA, Okla. – The Metropolitan Tulsa Transit Authority today announced the addition of a bus powered by General Motors’ diesel-electric hybrid propulsion system to its mass transit fleet. The city of Tulsa is the 33rd community to invest in transit buses powered by General Motors’ hybrid technology, which offers greater fuel economy and reduced emissions than conventional diesel buses.
Attending a media event marking delivery of the GM hybrid-powered bus were Oklahoma Secretary for the Environment Miles Tolbert and representatives from Tulsa Transit, General Motors and INCOG, a voluntary association of local governments serving Creek, Osage, Tulsa, and Wagoner counties in Oklahoma.

"This new hybrid bus is a great addition to our fleet,” said Tulsa Transit General Manager Bill Cartwright. “It will serve as a reminder to all of us that we really do have clean air transportation alternatives available. This is important because Tulsa has serious air quality issues related to ozone levels.”

Buses powered by GM’s advanced hybrid propulsion technology deliver significantly better fuel economy than traditional buses and produce up to 60 percent fewer oxides of nitrogen emissions and 90 percent fewer particulate, hydrocarbon and carbon monoxide emissions. Other benefits of the buses include reduced maintenance costs resulting from extended brake, engine oil and transmission oil life; superior torque, providing 50 percent faster acceleration compared with conventional diesel buses, and operational sound levels approaching that of passenger cars.

Since 2004, 430 GM hybrid-powered buses have been delivered to communities in the U.S. and Canada, including Yosemite National Park in California. The estimated annual combined fuel savings for the 430 GM hybrid-powered buses is 625,000 gallons.

“The General Motors hybrid diesel-electric drive system for buses uses the most efficient parallel hybrid architecture available in the world today,” said Tom Stephens, group vice president of GM Powertrain. “If the U.S. had only 1,000 GM hybrid powered buses operating in major cities, the cumulative savings would be more than 1.5 million gallons of fuel annually.”

By the end of the year, another 237 GM hybrid-powered buses are expected to be delivered to several cities.

The clean hybrid technology is manufactured by GM Allison Transmission, maker of transmissions and hybrid propulsion systems for commercial trucks, buses, off-highway equipment and military vehicles, headquartered in Indianapolis. Gillig Corp. of Hayward, Calif., manufactured the bus .

The hybrid technology in these buses has served as the starting point for GM’s co-development with DaimlerChrysler and BMW Group of a 2-mode hybrid system that GM will launch next year in the Chevrolet Tahoe and GMC Yukon fullsize SUVs, followed by the Cadillac Escalade in 2008.

General Motors Corp. (NYSE: GM), the world’s largest automaker, has been the global industry sales leader for 75 years. Founded in 1908, GM today employs about 327,000 people around the world. With global headquarters in Detroit , GM manufactures its cars and trucks in 33 countries. In 2005, 9.17 million GM cars and trucks were sold globally under the following brands: Buick, Cadillac, Chevrolet, GMC, GM Daewoo, Holden, HUMMER, Opel, Pontiac, Saab, Saturn and Vauxhall. GM operates one of the world’s leading finance companies, GMAC Financial Services, which offers automotive, residential and commercial financing and insurance. GM’s OnStar subsidiary is the industry leader in vehicle safety, security and information services. More information on GM can be found at www.gm.com.
