Cummins ISX 15

BIG-BLOCK ARCHITECTURE, OPTIMIZED FOR FUEL ECONOMY

With ratings from 400-550 hp, and 1650-1850 lb-ft of torque, the 2017 ISX15 is well suited for fleets in freight applications that require fuel economy and the benefits of bigger block architecture. The economy-focused engine is optimized to deliver peak torque at lower engine speeds and enable down-speeding without compromising drivability.
