Cummins ISX Diesel Engine
385–600 HP of Heavy-Duty Muscle
Power: 385 – 600 HP (up to 620 HP on select calibrations) | Torque: 1,450 – 2,050 lb-ft
Applications: Class 8 linehaul tractors, heavy-haul, dump trucks, mixers, and vocational fleets
First launched in 1998 as the successor to the N14, the Cummins ISX quickly became the benchmark for power, fuel efficiency, and emissions compliance in the heavy-duty trucking industry. Key milestones include the ISX15 upgrade with EGR, DPF, and SCR aftertreatment (EPA 2010) and ongoing refinements to SmartTorque™ and electronic controls that deliver big-block horsepower while trimming diesel spend.
Why Fleets Choose the ISX
- Massive Torque Plateau — up to 2,050 lb-ft for effortless hill climbs and fewer shifts.
- FuelSmart Technology — high-pressure common-rail injection, VGT™ turbo, and advanced ECU mapping maximize MPG.
- Rugged Reliability — forged internals, robust cooling, and long service intervals keep uptime high and lifecycle costs low.
- Emissions Ready — integrated EGR, DPF, and SCR systems meet the latest EPA/CARB standards without sacrificing performance.
