Cummins X15 Overview
BIG-BLOCK ARCHITECTURE, OPTIMIZED FOR FUEL ECONOMY
With ratings from 400-500 hp, and 1450-1850 lb-ft of torque, the X15 Efficiency Series 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 driveability.
