The Cummins B6.7 propane is a 6.7-liter displacement engine that will be built on Cummins recently announced fuel-agnostic B-series platform and powered with propane autogas. The new engine will provide fleet owners with diesel-like performance and durability, uptime and low total cost of ownership, with power expected ratings between 280–360 hp and 600–860 lb-ft of torque, according to the Propane Education and Research Council (PERC).
The B6.7 Propane is suited for several applications, including medium-duty truck, vocational, school bus, and terminal tractor markets, making it a low-emissions solution designed to meet or exceed EPA and CARB regulations in 2024 and beyond.
Medium-duty fleets that use propane autogas benefit from a reduced total cost-of-ownership thanks to low costs for fuel, maintenance, and refueling infrastructure. As an abundant and affordable energy source, propane autogas allows fleet owners to integrate lower emission vehicles with minimal disruption to their operations, making a bigger impact on the environment, PERC noted.
