Michelin also worked with DTNA on the SuperTruck
prototype, providing specially formulated low rolling-resistance tyres.
By carefully masking in the oil cooling gallery, piston rings were cooled almost the same manner with baseline piston (this point is different from Cummins SuperTruck
I technology, reduce or cut the oil flow in the cooling gallery), whereas the back side of the cavity was insulated not to pass through the heat to the oil even though there still remains some passages of heat flux.

fuel efficiency program will yield savings to the trucking industry in the near term, and in the longer term we'll see a strong challenge from autonomous trucks--which will keep a lid on trucking costs and therefore constrain rail rates.

exceed the required 50 percent efficiency improvement, and deliver a 75 percent more efficient truck ahead of schedule.
