Cummins is looking to the future with a turbocharged four-cylinder E85 engine.
Yesterday, the company unveiled its new Ethos 2.8-liter turbocharged four-cylinder engine that runs on E85 and provides 250 hp and 450 lb-ft of torque. The engine is being developed with partial funding from the California Energy Commission in hopes of producing a low-carbon, medium-duty commercial engine.
According to Cummins, the engine has specific tuning to take advantage to take advantage of the unique properties found in E85 and is projected to cut CO2 emissions by as much as 50 to 58 percent on corn-based ethanol and as much as 75 to 80 percent with cellulosic-based ethanol. The company is currently testing the powerplant with an Allison 2000-series transmission with auto start-stop to further enhance fuel economy.
Still currently in the testing phase, no timeline for production or availability has been announced.
