During an event held Tuesday, Aug. 29, 2017 at the Cummins Technical Center in Columbus, IN, employees, company executives, global media and elected officials watched as Cummins unveiled a prototype fully electric class 7 demonstration Urban Hauler Tractor.

The demonstrator truck uses a 140 KWh battery pack instead of a 12-liter engine. The weight of the electric powertrain is roughly equal to that of the removed engine, aftertreatment, transmission and fuel tank. The tractor day cab when paired with a trailer has a gross vehicle weight rating limit of 75,000 lbs. The concept truck has a range of about 100 miles on a single charge for city driving that’s extendable to 300 miles with additional battery packs. The powertrain and truck will enable Cummins to learn more about the potential electrification holds for larger vehicles. 

A regenerative braking system and the potential for solar panels on the trailer roof can send energy to the battery pack. Air drag is reduced by replacing side mirrors with an in-dash camera system. The truck achieves a significant air drag reduction via its highly streamlined design as well as a better sealed truck body and underbody – with no front radiator intrusion.

Even with the announcement, Cummins adds that diesel engines aren’t going away. The company expects diesel to be a popular option with customers for years to come. Cummins has and will continue to produce the cleanest diesel engines in the world, reaching near zero emissions levels.
