April 22, 2022

Cummins B6.7 Propane engine is for medium-duty fleet owners and is a 6.7-liter displacement unit that will be built on Cummins recently announced fuel-agnostic B-series platform and powered with propane Autogas.

Backed by data and support from the Propane Education & Research Council (PERC), the new engine offers fleets a path to decarbonization without compromising on performance or range, PERC says. The engine is designed to provide fleet owners with diesel- like performance and durability, uptime, and low total cost of ownership, with power expected ratings between 280 and 360 horsepower with 600 to 860 lb.-ft. of torque. The B6.7 Propane is suited for several applications, including medium-duty truck, vocational, school bus, and terminal tractor markets.
