Kenworth unveiled its SuperTruck 2 concept at the Advanced Clean Transportation Expo 2024 in Las Vegas. Over six years of development under the DOE's SuperTruck 2 program, the high-efficiency tractor showcases a revolutionary design with the driver's seat positioned in the center of the cab. The vehicle boasts a 136% gain in freight-ton efficiency, achieved through aerodynamic enhancements and weight reduction, enhancing fuel economy up to 12.8 miles per gallon. The truck features a hybrid system with a 48-volt electric generator and lithium-ion batteries, showcasing a 55.7% engine efficiency improvement. Innovations like digital mirrors, variable suspension, and a redesigned sleeper berth highlight the vehicle's futuristic design. Kenworth aims to integrate these technologies into future production models, making the SuperTruck 2 a trailblazer in the transportation industry. Despite being diesel-powered, the truck is adaptable to various powertrains including fuel cells, hydrogen tanks, natural gas tanks, or batteries without cab modifications.
