Video: Volvo Group Unveils CO2 Free Trucks

The Volvo Group announces plans to produce seven demonstration trucks that use varying forms of alternative fuels. Volvo officials say they created the vehicles to help curb European statistics that indicate cargo transportation contributes an estimated 4 to 5 percent of all global carbon-dioxide emissions. The seven Volvo FM trucks, which were unveiled in Stockholm on Aug. 29, are equipped with 9-liter diesel engines.
