Cummins X12 Diesel For MCI Coaches

Cummins Inc. announced that beginning in 2019, its X12 diesel engine will power motor coaches from Motor Coach Industries (MCI), a subsidiary of New Flyer Industries Inc. (NFI Group).

Available in ratings to 455 hp, the X12 diesel is designed to be compact and lightweight, with a sculpted engine block that helps deliver an engine weight of 2150 lb. The XPI fuel system is a scaled down version of the fuel injection technology used on the flagship X15 engine, and the engine also incorporates a variable geometry turbocharger from Cummins Turbo Technologies and the Single Module aftertreatment system from Cummins Emission Solution, which is takes up to 60% less space and weighs up to 40% less than prior aftertreatment configurations, Cummins said.

Combined engine and aftertreatment weight for the X12 is around 2340 lb., which Cummins said is significantly lower than other heavy-duty engines.

The reduced size and weight of the X12 package results in better serviceability standpoint, said Patrick Scully, MCI executive vice president of Sales. “We are always looking for ways to improve the service and maintenance efficiency for technicians,” Scully said. “Validation work for the new engine has been underway since 2017 and will continue through to product launch in 2019, but by providing the latest technologies and the lightest heavy-duty engine in its class, we expect our customers to experience the lowest total cost of ownership with MCI coaches.”

The X12 will be available in MCI’s J4500, D-Series, Commuter Coach and Inmate Speciality Coaches.
