Cummins Inc. has announced the availability of two new 450-HP ISX12 ratings for linehaul and regional-haul truck markets: The 450 ,HP with 1,650 lb./ft. of peak torque and 450 HP with 1,450/1,650 lb./ft. of peak torque.
The 450 HP engine with 1,650 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, Cummins said. The 450 HP with 1,450/1,650 lb./ft. of peak torque 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, according to the company.
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.
