Volvo Trucks: Where Ambition Meets Efficiency
Can innovation change the heavy-duty transportation industry? That's the question posed by SuperTruck II, a project driven by Volvo Trucks North America and the U.S. Department of Energy (DOE). This is a story about ambitious goals, achievements, and the relentless pursuit of a more efficient future.
The DOE initiated the SuperTruck II program as a public-private partnership with a clear goal: to achieve a 100% improvement in freight efficiency from a 2009 baseline. Volvo Trucks North America, led by Peter Voorhoeve, accepted the challenge with open arms. The result? A groundbreaking 134% improvement in ton-mile-per-gallon efficiency.
Peter Voorhoeve, president of Volvo Trucks North America, shared his perspective: “Partnering with the DOE on the SuperTruck program is an exciting opportunity to push the technology envelope to see what's technically possible for heavy-duty transportation and what solutions can be scaled to production. It's equally important to understand what solutions can't be scaled to production. We're very proud of the results of our Advanced Engineering team. A program that pushes the envelope in every way - creativity, problem-solving, feasibility, and innovation.”
One of the standout features of SuperTruck II is its impressive design. The front of the truck is shaped like a wedge to reduce air resistance and improve aerodynamics. This streamlined design allows the truck to move faster and more smoothly. Additionally, they incorporated a curved windshield and a reduced-size cooling system to further enhance energy efficiency.

A significant aspect of the SuperTruck II project is weight reduction. The truck and trailer combo managed to drop a massive 27,000 pounds in weight. This was achieved through a strategic decision to use a 4x2 configuration, which is less common in the U.S. but often used in Europe for payload efficiency. While the design allows for adaptability to 6x2 or 6x4 configurations, the focus was on a lightweight yet durable structure.
To achieve such significant weight reduction, the project utilized advanced materials like high-strength steel and lightweight alloys, which provided both durability and decreased weight. Additionally, innovative design choices such as aerodynamically optimized side skirts and trailer tails contributed to lower drag and higher fuel efficiency. These materials and design choices play a crucial role in enhancing the truck's overall performance and sustainability.
Moreover, the success of SuperTruck II was not solely due to Volvo Trucks' innovation. They collaborated with a trailer company to create a custom lightweight trailer. This partnership was essential in achieving the overall weight reduction goal. When they combined all the parts of the semi-truck, it resulted in a perfect combo, presenting the appearance of a single unit and further reducing drag. The seamless integration of these components highlights the importance of collaboration and strategic partnerships in driving innovation.
Another notable innovation in SuperTruck II is the integration of hybrid technology. By combining a diesel engine with an electric motor, the truck benefits from improved fuel efficiency and reduced emissions. This hybrid system enables regenerative braking, which captures energy usually lost during braking and stores it for future use, further enhancing efficiency. The hybrid technology represents a significant step towards greener and more sustainable heavy-duty transportation.
Practical testing in real-world conditions was crucial for this project. Voorhoeve emphasized the importance of these tests: "We made sure to test SuperTruck II in real driving situations to ensure its viability and effectiveness."
