Cummins ISX12 Gets New Ratings

Rolf Lockwood

Cummins has announced  two new 450-hp ISX12 ratings for linehaul and regional-haul markets.

Cummins ISX12, now with new 450-hp ratingsFirst released in 2010, the ISX12 has filled needs in several markets from regional and bulk hauls to refuse and mixer.

The two new 450-hp ratings offer 1650 lb ft of peak torque or 1450/1650 lb ft. The former is said to provide performance on the same level as 15-liter and 13-liter engines but at a much lighter weight. The 1450/1650 lb-ft SmartTorque rating is meant for applications like tank and bulk hauling with heavy material on the way out and a light or empty load on the return trip. The technology modulates output to deliver only the amount of torque needed for the work being done.

Cummins is continuing to work on expanded ratings for vocational trucks.

The ISX12 will continue to be the company’s vocational and regional/bulk-hauling offering through 2017, and will be available through the end of 2018, with  the next-generation X12 launching at the start of 2018.
