With new 450-hp rating, Cummins ISX12 continues to exceed toughest demands

Aug. 31, 2016

Cummins Inc has announced the availability of two new 450-hp ISX12 ratings for linehaul and regional-haul truck markets.

Since its release in 2010, the ISX12 has performed enormously well across a wide range of trucking applications, from regional-haul and bulk-haul to refuse and mixer. This versatile engine, with its unmatched Power Take-Off (PTO) capabilities, continues to delight customers who demand more from their medium-bore engines. Over the years, Cummins has continuously refined the ISX12 to ensure that it not only meets performance expectations, but also brings competitive fuel economy and overall increased productivity to customers with the highest expectations.

The new 450-hp ISX12 ratings for linehaul and regional-haul trucks are as follows: 450 hp with 1650 lb-ft of peak torque and 450 hp with 1450/1650 lb-ft of peak torque. The 450 hp with 1650 lb-ft of peak torque provides performance on the same level as 15-liter and 13-liter engines but at a much lighter weight, which means more payload capacity. The 450-hp 1450/1650 lb-ft SmartTorque rating is ideal for applications like tank and bulk haulers that transport heavy material on the way out, but return with a light or empty load. SmartTorque technology modulates torque output to deliver the adequate amount of torque needed for the work being done.

Along with these new ratings for regional-haul trucks, Cummins is continuing to work on expanded ratings for vocational trucks, to provide even greater productivity beyond its current leadership position in ISX12-powered cement mixers, refuse and vacuum trucks.

The ISX12 will continue to be Cummins vocational and regional/bulk-hauling champion through 2017, and will be available through the end of 2018, with Cummins launching the next-generation X12 at the beginning of 2018.
