Ram and Cummins have a long-standing relationship within the realm of diesel engines, but the supplier has introduced a new concept that has nothing to do with diesel at all. In fact, it’s all electric.
Cummins revealed its diesel semi truck concept, called the Urban Hauler Tractor. It’s a class 7 semi truck with a 44,000-pound payload, which Cummins believes could be ready by the end of the decade. It also beats Tesla to the punch, which will introduce its electric semi truck this month.
Even if the Urban Hauler Tractor isn’t ready by the end of the decade, Cummins is optimistic the powertrain will be ready for duty. The electric motor and 14o-kilowatt-hour battery pack provide 100 miles of range. The figure is well below what truck drivers are used to traveling, but Cummins says a diesel engine could be outfitted to act as a range extender.
Additionally, Cummins says the massive battery pack could be charged in as little as 20 minutes by the time it’s ready for production. Charge times for the battery pack today would hover around one hour with present-day technology.
It will likely be sometime before electric semi trucks gain momentum, but Cummins isn’t counting the powertrain out as it readies its next-generation diesel engines at the same time. Those are due in 2022.
