ISX12. Better. From Start To Finish.
Cummins ISX12 builds on the legacy of the ISM and proven technology of the ISX15 to deliver better fuel economy, performance, reliability and durability. It has more horsepower and more torque, plus stronger acceleration – all in a compact design. It achieves near-zero emissions and reduces noise output. With 450-500 hp (336–373 kW), power output is a perfect match for every kind of motorhome.
Optimized calibrations have resulted in significant fuel economy gains for the ISX12 versus the ISX11.9.
Cummins is the only engine manufacturer to design and develop, manufacture and support every component from the air intake to the exhaust aftertreatment in a totally integrated system.
The XPI fuel system is capable of the highest injection pressures in the industry, with a common-rail design that delivers strong performance independent of engine speed. The integrated system of the ISX12 also includes a VGT™ Turbocharger custom-built by Cummins Turbo Technologies.
