Kenworth recently unveiled its cutting-edge innovation, the SuperTruck 2, at the Advanced Clean Transport expo in Las Vegas. This new truck, developed through a six-year collaboration with the U.S. Department of Energy, focuses on enhancing freight efficiency while still utilizing diesel as the primary energy source.
The SuperTruck 2 has exceeded expectations by achieving a remarkable 136% improvement in efficiency compared to the 2009 Kenworth T660, which was known for being the most fuel-efficient truck at the time. This achievement was made possible through advancements in fuel efficiency, reaching up to 12.8 mpg, and a significant reduction in weight by over 7,000 pounds.
One of the standout features of the SuperTruck 2 is its aerodynamic design, which resembles a bullet train with a central cockpit, a narrowed nose, and a sloped forehead. Additionally, the truck includes low skirts, fully enclosed wheels, and slim camera stalks with night vision capabilities, replacing traditional side mirrors. These design elements contribute to a 48% reduction in drag.
Weight savings were also a significant factor in the development of the SuperTruck 2. The tractor and trailer combined weigh 26,100 pounds, representing a reduction of 7,100 pounds compared to a typical configuration. This weight reduction was achieved through the use of lightweight, low-rolling-resistance tires, a smaller fuel tank, and innovative materials and design considerations.
The power train of the SuperTruck 2 is equally impressive, featuring a PACCAR MX-11-based diesel engine, a TX-12 automated transmission, and a 48-volt electric generator to create a mild hybrid system. This system charges lithium-ion batteries through regenerative braking, powering various systems in the truck.
For drivers, the SuperTruck 2 offers a unique experience with a panoramic view from the central cockpit, a configurable 15-inch digital display, and a sleeper berth with a fold-down bed and rotating tabletop for added convenience.
While the SuperTruck 2 currently runs on a diesel engine, Kenworth has designed the layout to be adaptable to accommodate battery-electric or hydrogen fuel cell-powered drive systems in the future. This forward-thinking approach aims to address the challenges of achieving a carbon-neutral society by 2050.
In conclusion, Kenworth’s SuperTruck 2 represents a significant leap forward in innovation and efficiency in the trucking industry. While this particular truck may not go into production, the technologies and design concepts developed during this project could pave the way for more efficient, eco-friendly, and driver-centric commercial vehicles in the future. The transition from diesel to alternative energy sources in freight transport is a crucial step towards a more sustainable future.
