The SuperTruck 2 presents a multitude of aerodynamic improvements that collectively slash wind resistance by 48%. These include a sleeker shape, fully enclosed wheels, and digital side mirrors. Its advanced features don't just bolster performance but also pilot safety and visual cues with expressive lighting and an adjustable suspension system for enhanced aerodynamics or maneuverability.
Inside the cabin, drivers are greeted with a central seating arrangement, complemented by a comprehensive 15-inch digital instrument panel. The interior is made cozy yet functional with amenities such as a convertible sleeping zone featuring a fold-down bed over a sofa and an array of rear air vents.

Under the hood lies the PACCAR MX-11 engine, capable of churning out 440 horsepower. The truck integrates a 48V mild hybrid system energized by state-of-the-art lithium-ion batteries powering several vehicular components like fans and steering mechanisms. This setup boosts engine efficiency from 47% to an impressive 55.7%, consequently uplifting fuel efficacy by approximately 10%.
In addition to a more efficient engine, the SuperTruck 2 and its trailer are surprisingly lightweight. Kenworth says the tractor and trailer weigh a combined 26,100 lbs (11,839 kg), which is 7,100 lbs (3,221 kg) less than a typical setup.
To help reduce mass, they're equipped with ten concept tires that save 355 lbs (161 kg) of weight and have extremely low rolling resistance. The more efficient engine also allowed for the use of a smaller 80-gallon (303-liter) fuel tank, which saves weight without sacrificing range.
Additionally, SuperTruck 2 accommodates future tech adaptations seamlessly. It’s designed to fit alternate fuel modules such as hydrogen or natural gas setups without reconstructive changes to its architecture.
Kenworth general manager Jim Walenczak commented on the progress achieved through this prototype saying, "SuperTruck 2 provided us with the opportunity to investigate new technologies in an early stage. We learned what worked and what didn’t. As a result, we are able to commercialize new technologies much quicker than we would have otherwise.”
