The Kenworth SuperTruck 2 was unveiled at the ACT Expo in Las Vegas, and it looks to be more spaceship than semi truck. It was developed over a six-year period as part of a collaboration with the Department of Energy’s (DOE) SuperTruck program, designed to challenge truck makers to improve freight efficiency using a diesel engine as the main power source.
Power comes from a PACCAR MX-11 engine generating 440 hp, mated to a PACCAR TX-12 automated transmission, and paired with a 48-volt electric generator. This results in a ‘mild’ hybrid system that leverages next generation lithium-ion batteries, which are recharged through regenerative braking. This enables SuperTruck 2 to operate electric fans, electric steering, and power for electric coolant and HVAC pumps, which were previously mechanically driven.
- 3 vehicle toy sets in 1 box – Boys and girls ages 7+ can build and rebuild 3 different sets using the same bricks with this LEGO Creator 3 in 1 toy
- Endless play possibilities – Kids can play out action and races with 3 different vehicle sets: a truck toy and helicopter toy, a plane toy and fuel truck, or a hot rod and SUV car toys
- Moving vehicle toys – Each model has movable features, including the wheels on the toy cars, the propellers on the plane and the rotor blades on the helicopter toy



The goal was a 100% freight efficiency improvement over our 2009 Kenworth T660, which at the time was arguably the most fuel-efficient truck in the industry. We surpassed the performance of that model to improve efficiency by up to 136%. This was realized through a combination of improving fuel efficiency up to 12.8 mpg while reducing our combination weight by more than 7,000 pounds. The result was the ability to haul more payload with an ultra-fuel-efficient tractor-trailer combination,” said Jim Walenczak, general manager of Kenworth and PACCAR vice president.
