"SuperTruck" Achieves 54% Fuel Efficiency Enhancement


peterbilt-supertruck-628A truck called the “SuperTruck” has achieved fuel efficiency 54% greater than that of average long-haul trucks. The SuperTruck achieved 9.9 MPG under real-world driving conditions, while typical long-haul trucks achieve 5.5 MPG to 6.5 MPG. Doesn’t sound like much, but this improvement is actually huge.

The SuperTruck was created out of a partnership with Cummins and Peterbilt Motors. It was estimated that this fuel economy improvement would save drivers $25,000 annually based on today’s average diesel prices, if they drive 120,000 miles per year. These vehicles also exhibited an even higher freight efficiency improvement of 61% compared to a baseline truck driving the same route. Both fuel efficiency increases exceeded the U.S Department of Energy’s goal of 50%.

The efficiency improvements were achieved using a more efficient engine, a waste heat recovery system, electronics that choose the most efficient routes for drivers, low-rolling-resistance tires, weight reductions, and a more aerodynamic chassis. Sometimes people marginalize the inefficiency of large trucks such as trailers used to transport garbage, food, and other items in large quantities. But everytime gas costs go up, so does the cost of shipping products. These fuel economy improvements can keep shipping costs in check.

  • Exceptional! Fact remains however: the electric age is upon us and these relics of the 20th Century American Golden age, fuelled by the Cheap Oil Era, face stiff competition from electric bullet trains decade of successes in China in particular, even carbon super capacitors with energy densities approaching, even exceeding that of gasoline and a new Israeli concept an electric car with aluminium pallets, and a range of 1000 km. – all these scalable, and the moment fossil fuel prices exceed the cost for the newer systems, the flip flop is expected. Today the White Zombie dominates drag strips, and another is well on the way. Electric dragsters where the practicality of spark ignited fuel peaks and electric torque monsters begin. Steel wheeled rail will always be cheaper energy-wise than rubber on the road, and high speed rail by any other than American definitions is taking over. Welcome to the 21st century.

    • @ Bruce, Name any 2 streets in NYC, Dallas or Seattle that your bullet train can deliver frozen food to. If you want anything in the USA,’Trucks Bring It’! I’m impressed with the new Cummins/Peterbuilt design.

        The same sort of argument was made supporting horses about a century ago,,,.

    • How much would this electric train cost? Would the new train have to have constant inspections for levelness on the tracks? Would the train be magnetic drive?

        Having spent the last month riding electric trains (including HSR) around Europe and North Africa I’m totally a believer in electric rail.

        HSR can replace airplane travel for moderate length trips – while moving a bit slower the savings in boarding/security makes the trip about the same length and comfort is much higher,

        We could move a lot of our truck cargo onto rail cars. Ship at night when passenger loads are less. Get the goods there faster and with less energy. Plus use renewable energy rather than fossil fuels.

        • Our rail system, specifically CSX, can move a ton of freight 468 miles on one gallon of fuel. Now that is efficient use of fuel.

  • I would like to know the SPEED this truck was operated at.Most states have truck speed limits over 55 mph. If this truck, for example, cruised I10 throughTexas at 55, it would have presented a major hazard, and driving that area at 55 is not feasible – especially with the 11/14/70 rule keeping Drivers from profiting. In my opinion, real world driving must include operating at speed with the flow of traffic.Installing Hydrogen generators would significantly increase mileage, power and reduce emissions and motor operating temperature. Since a generator can be constructed for about $50.00 each ( and filled with regular tap water and a catalyst I will not mention) there is no reason this feasible add on cannot be done – with the exception of the “fear of the unknown”.

    How about somebody doing a study on this? I have a lot more information on this, if anybody cares!!

    Kudos on the truck though – that IS a significant improvement – although it CAN be much better!!

  • A 54% improvement in efficiency is NOT “54% Efficiency.” You need to change your headline.

    • … because in your news feed the “enhancement” part gets cut off and it just looks like “54% efficiency”
