Sleek, stylish, and bullet train-like, the Kenworth SuperTruck2 made its debut at the ACT Expo in Las Vegas, developed over a six-year period as part of a collaboration with the Department of Energy’s (DOE) SuperTruck program.
This semi truck is powered by a PACCAR MX-11 engine making 440 hp, paired with a 48-volt electric generator, mated to a 12-speed automatic transmission. Its batteries are recharged through regenerative braking, enabling SuperTruck2 to operate electric fans, electric steering, and power for electric coolant / HVAC pumps. Kenworth discovered that the mild hybrid based 48-volt auxiliaries and energy waste recovery recorded a program record 55.7% engine efficiency.

There were a lot of things that contributed to weight savings. The 10 new concept tires we used weighed 355 pounds less than ‘like’ tires currently on the market, and those tires also had an extremely low rolling resistance – measuring 4.2 on the CRR scale versus 5.0 for typical high-efficiency tires. We also found that less fuel was required with the more fuel-efficient powertrain – this allowed us to put on a smaller 80-gallon fuel tank to go the same distance as before. So, here again, we’re saving weight. It all builds upon itself,” said Joe Adams, Kenworth’s chief engineer.
