A new SuperTruck is a huge improvement over current long-haul trucks that ship tonnes of goods around North America. The USA’s Department of Energy wanted to make trucks 50% more efficient through various solutions, even a marginal increase can lower gas consumption and thus pass on savings to a consumer.
The demonstration SuperTruck made a whole swath of changes (as can be seen in the image above) to make their truck way better than existing fleets. All their changes add up to a 61% improvement in freight efficiency!
This was achieved without anything too exotic: The ‘SuperTruck’ uses a higher-efficiency engine and an aerodynamic tractor-trailer that significantly reduces drag combined with a waste heat recovery system, electronic controls that use route information to optimize fuel use, low-rolling resistance tires, and weight reductions all around.
