Cummins’s Lori Thompson, vice president of truck and bus OEM business, said the ISX12 diesel engine will be available with the SmartAdvantage powertrain in coming months and provide a 2 to 4 percent fuel economy savings. It will be offered as a small-ratio-step overdrive model with two new Cummins ISX12 SmartTorque2 ratings: the ISX12 370ST2, with torque of 1150 lb-ft to 1450 lb-ft, and the ISX12 425ST2, with torque of 1350 lb-ft to 1650 lb-ft.
“The latest SmartAdvantage Powertrain offerings are a natural extension of the initial product, and will provide customers with the fuel economy and productivity improvements they desire, along with a broad range of applications to meet their specific hauling needs.”
John Beering, Senior Vice President and General Manager – Commercial Vehicle Transmission Business, Eaton, said the ISX15 SmartAdvantage soon will be available for 110,000-lb GVW applications later this year, primarily to serve heavy-haul customers in Canada.
In other news, the companies announced an integrated powertrain package for the Cummins Westport ISX12 G natural gas engine and Eaton UltraShift Plus automated transmission in the North American market. The new pairing will initially be available in regional and linehaul applications mid-year.
