The Kenworth Truck Company
a new Class 6 hybrid-electric truck model, the Kenworth T270 at the Mid-America Trucking Show. The T270 is powered by the new PACCAR PX-6 engine with an integrated transmission-mounted motor/generator linked to a 340-volt battery pack. A dedicated power-management system switches the powertrain between "
mode" above 30 mph and "
mode" below 30 mph when the diesel engine gets an electric boost to improve
in stop-start conditions. A reduction in diesel consumption of 30 percent should be possible in stop-start traffic.
Analysis: In addition to increased fuel economy and reduced emissions, having the battery pack on-board gives Kenworth the chance to offer an electric power-take-off for utility customers. Is there a single major truck company not committed to hybrid powertrains now?
