By the time the Cummins/Peterbilt SuperTruck made its public debut in February boasting 10.7 mpg, some contemporary trucks were achieving better than 8 mpg, and some super-fuel-conscious fleets boast even higher. While that may make the SuperTruck accomplishment seem slightly diminished, that 10.7-mpg milestone is only a small part of the story.
The Peterbilt-Cummins SuperTruck project achieved almost-unheard-of gains of 68% in freight efficiency over a 24-hour duty-cycle, a 50% improvement in freight efficiency on an 11-hour drive-cycle and a 20% improvement in the thermal efficiency of the engine. How did they do it, and what does that mean?
This series of photos reveals most of the secrets behind the effectiveness of the SuperTruck, particularly its aerodynamic enhancements. No stone was left unturned by engineers who were looking for every possible aero advantage. Some of what you see here will soon make its way onto production vehicles, while other enhancement may still be a few years off. (Photos: Jim Park)
