Cummins expands ISX15 ratings options

Cummins Inc. has released three new ISX15 ratings: 475-, 450- and 400-HP ratings with 1850 lb.-ft. of torque, which the company says will provide an optimal blend of performance and fuel efficiency for high-load applications or fleets that frequently encounter mountainous terrains and require strong pulling power.

Customers that typically operate in high-load conditions (gross combined vehicle weight over 80,000 lb) or in mountainous terrains, and want to achieve better fuel economy should consider the 1850 lb.-ft. torque ratings, Cummins explained. Customers that typically operate in light-load conditions (GCVW below 80,000 lb) or in hilly or flat terrains with achieving maximum fuel economy as an operational goal, should continue to use ISX15 SmartTorque ratings with up to 1750 lb.-ft. torque, according to the company.
