Hybrid Bus Transit Now Available In Indianapolis

GM Delivers Hybrid Power For Buses Added To IndyGo Transit Fleet

INDIANAPOLIS January 24, 2005; IndyGo demonstrated its on-going commitment to clean air and new transportation technology today by announcing the addition of two new hybrid transit buses powered by three Indiana based companies - GM Allison Transmission, Cummins Inc., and Remy International Inc.

IndyGo and the city of Indianapolis join the growing ranks of communities investing in transit buses powered by General Motors' hybrid technology, which offer greater fuel economy and dramatically lower emissions over conventional diesel buses.

The buses will begin servicing the city on February 1.

"We are extremely pleased to be a part of a partnership that supports the state of Indiana in a number of significant ways," said Gilbert Holmes, president/CEO of the Indianapolis Public Transit Corporation. "Public transit systems like IndyGo play an important role in the Indiana economy by providing an effective pollution mitigation alternative for daily commuters; offering safe, reliable transportation that supports valued workers and their employers; and supporting Indiana's economy through its support of high quality technology providers like General Motors Allison Transmission and Cummins Inc."

GM hybrid-equipped buses are operating in 18 U.S. cities including Seattle, Minneapolis, Portland, Salt Lake City, Houston and Austin, and a fleet will soon be operational in Yosemite National Park.

"Our GM hybrid diesel electric drive system for buses use the most efficient hybrid architecture available in the world today," said Larry Dewey, president of GM Allison Transmission. "We think it is an excellent investment for urban transit bus fleets."

In addition to improved fuel economy and dramatically lower emissions, the GM hybrid system delivers superior torque, derived from the dual electric motors used to launch from a stop; 50 percent better acceleration than conventional diesel buses; and operation sound levels equal to passenger cars, even in tunnels. The hybrid powertrain also helps to extend brake, engine oil and transmission oil life.

The clean hybrid technology is manufactured by GM Allison Transmission, manufacturer of transmissions and hybrid propulsion systems for commercial trucks, buses, off-highway equipment and military vehicles, headquartered in Indianapolis. The hybrid propulsion system uses electric motors manufactured by Remy International Inc., a leading global producer of starters, alternators and electrical components, with its world headquarters in Anderson. The buses are also powered by a 5.9-liter diesel engine manufactured by Cummins Inc., a global power leader that designs, manufacturers and distributes and services engines and related technologies, headquartered in Columbus. Additionally, Gillig Corp. of Hayward, Calif, which is the second largest producer of transit buses in North America, manufactures the transit buses.

"Cummins and Allison are at the forefront of emerging diesel-electric hybrid technology designed to dramatically lower emission levels, reduce noise and improve fuel-efficiency," said Roe East, general manager, Cummins Worldwide Bus Business. "As local Indiana companies, we are both proud to be part of a partnership that will deliver hybrid power for the IndyGo transit fleet transporting passengers to their jobs daily."
