Mich. - General Motors Corp. will produce a full-size pickup truck
featuring a hybrid powertrain beginning in 2004, underscoring GM's
intent to remain the nation's fuel-economy leader.
light truck fuel efficiency today is 4 percent better than Ford's. Pearce
also announced that GM and its Allison Transmission Division will begin
delivery this year of a "hybrid" powertrain for transit buses.
"Buses might be the single most important step to reduce
transportation emissions for the U.S. or any other country," Pearce
said. "There are about 13,000 transit buses in service in the nine
largest U.S. cities. If we could replace those buses with ones featuring
the GM hybrid system, this country would use nearly 40 million fewer
gallons of diesel fuel every year. To put that in context, that is the
equivalent fuel savings of 584,000 small cars with hybrid propulsion
two hybrid powertrains unveiled by GM will meet or exceed the power
performance of a conventional powertrain. GM full-size hybrid pickup
trucks, versions of the popular Chevrolet Silverado and GMC Sierra, will
deliver top performance with near 15 percent better fuel economy.
this year, GM will begin testing its hybrid pickups in demonstration
fleets in several U.S. cities. The demonstration will help GM engineers
understand what hybrid vehicle features and performance features are
important to pickup truck customers.
hybrid bus powertrain was designed and developed by GM Allison
Transmission Division based in Indianapolis. The GM Allison system will
offer 50 percent better fuel economy compared with a conventional
diesel-engine transit bus. The system also will cut nitrous oxide
emissions by 30 percent, while cutting particulate, hydrocarbon and
carbon monoxide emissions by 90 percent, when fueled with low-sulfur
Allison works with transit bus manufacturers who then sell the buses to
public and private transit systems. GM Allison is also developing hybrid
systems for other commercial vehicles.
