Kenworth’s innovative SuperTruck 2 concept semi has doubled efficiency through its bullet train-like aerodynamics and hybrid powertrain, setting a new standard for the trucking industry. This development marks a significant leap in the quest for sustainable and efficient transportation solutions.
After six years of meticulous development, the Kenworth SuperTruck 2 prototype was unveiled at the ACT Expo in Las Vegas. If Batman were to own a heavy-duty semi-tractor, it might very well resemble this sleek, futuristic vehicle. The SuperTruck 2’s design abandons the traditional tractor snout for a look akin to a motorcycle helmet, combining aerodynamic efficiency with a touch of intimidation.
The SuperTruck 2 is powered by a hybrid diesel powertrain that pairs a 440-horsepower PACCAR MX-11 engine with a 48-volt electric generator. This setup, enhanced by energy waste recovery technology, achieves an impressive engine efficiency of 55.7% on bench tests. A 12-speed automatic transmission completes the drivetrain, ensuring smooth and efficient power delivery.
Company News:
The prototype weighs 7,000 pounds less than its benchmark, the 2009 Kenworth T660, which was once considered among the most fuel-efficient trucks with an estimated 6 mpg. In stark contrast, the SuperTruck 2 reports an astounding 12.8 mpg, representing an overall efficiency increase of 136%. For long-haul drivers traveling 125,000 miles a year, this improvement translates into significant fuel savings, potentially redirecting those savings to other needs such as driver benefits.
Kenworth has not only focused on fuel efficiency but also on driver comfort and safety. The truck features a narrower front and a large, curved windshield for expansive visibility. Traditional mirrors have been replaced with a state-of-the-art camera system providing rearview monitoring, trailer tracking, and night vision enhancements, reducing drag and improving safety.
Inside, the SuperTruck 2 offers an adjustable sleeper berth that folds over the sofa, creating distinct sleeping and sitting areas. The versatile tabletop can be adjusted for various activities, from working to eating to relaxing. Additionally, a large driver-side door and extendable steps make getting in and out of the truck more convenient.
Earnings Reports and New Product Launches: Despite diesel’s uncertain future, Kenworth has designed the SuperTruck 2 to be future-proof. The truck’s layout is flexible, allowing it to be adapted for zero and near-zero emission technologies, including fuel cells, hydrogen tanks, natural gas tanks, and batteries.
The SuperTruck program, initiated by the U.S. Department of Energy (DOE) in 2009, aims to encourage efficiency improvements in Class 8 heavy-duty trucks. Kenworth, along with other major manufacturers like Cummins-Peterbilt, Daimler, Navistar, and Volvo, have made significant strides under this program, often exceeding the DOE’s goal of a 50% efficiency increase. These advancements span beyond engines to include improvements in tires, materials, and energy management.
Investment Advice and Trade Policy Impacts:
With the success of the initial SuperTruck program, federal funding opportunities have expanded. In 2016, SuperTruck 2 provided $80 million to four recipients, leading to innovations such as Navistar International’s hybrid semi. The DOE’s latest initiative, SuperTruck 3, announced in 2021, offers $127 million to five recipients. Additionally, the upcoming SuperTruck: Charged initiative allocates $72 million for charging infrastructure projects.
Industry Mergers and Economic Data Releases:
While these prototypes remain in the development phase, the technologies, designs, and materials they incorporate are already influencing production models. Kenworth’s SuperTruck 2 demonstrates that with the right investment and innovation, the trucking industry can achieve remarkable efficiency improvements, paving the way for a more sustainable future in heavy-duty transportation.
