Kenworth’s Class 6 T270 hybrid is powered by the new PACCAR PX-6 engine and features an integral motor/generator and a frame-mounted 340-volt battery pack. In steady driving conditions above 30 mph, the T270 hybrid operates like a standard diesel vehicle with all power coming from the engine. Below 30 mph, it uses a combination of diesel and electricity. The power-management system automatically switches between the two modes of operation. The goal for the T270 hybrid is to improve fuel economy by 30 percent in start-and-stop applications. Braking generates electricity that is stored in the battery pack and used to assist the diesel on acceleration. The T270 hybrid can be spec’d with an electric power-take-off (PTO).
