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 "diesel mode" above 30 mph and "hybrid mode" below 30 mph when the diesel engine gets an electric boost to improve fuel economy in stop-start conditions.

Industry organisation, Diesel Technology Forum, has announced that all major heavy-duty truck and engine manufacturers have met new Environmental Protection Agency standards for emissions cuts and have been certified by EPA for full production. To meet the new emissions requirements, new long-haul trucks are equipped with particulate matter filters which result in 2007 models being 90 percent cleaner than the previous generation. Nitrogen oxide (NOx) emissions have also been reduced significantl
