Volvo unveils hybrid driveline for construction trucks

| Friday, January 12, 2007

For a while now, manufacturers have been talking about hybrid personal vehicles that use electricity and other power sources in addition to gasoline or diesel.

That technology is now crossing over into truck markets, according to the Volvo Group.

Volvo unveiled a new construction truck on Wednesday, Jan. 10, that has a hybrid driveline. The U.S. Air Force helped develop the driveline, produced under a Mack subsidiary, Mack Granite, according to a press release.

Mack and Volvo brand trucks are manufactured under the Volvo Group umbrella.

Volvo's I-SAM - which stands for Integrated Starter Alternator Motor - saves up to 35 percent in fuel, depending on driving conditions and applications, according to the company.

Trucks with the I-SAM driveline are scheduled to go into production in 2009. The driveline is compatible with the Mack MP7 engine and automated manual transmission, and works by storing electrical energy recovered during braking.

As the technology continues to develop, heavy construction equipment could save up to 50 percent on fuel, Volvo reported.
