Cummins has announced three new horsepower ratings for its 2007 ISX, including a new 600 hp offering. The company also announced at the Mid-America Trucking Show it would be offering a full lineup of horsepower ratings for its ISM.
In addition to the 600 hp ISX, Cummins will also offer two other new ratings: the ISX 425 SmartTorque (ST) and the ISX 485 SmartTorque.
The ISX 425 ST delivers 1,550-1,750 lb. ft of torque. The higher torque ratings will allow drivers to remain in top gear longer, maintaining better road speeds and shifting less frequently on grades, Cummins officials said. Another benefit of remaining in top gear longer is improved fuel consumption, making the new ISX 425 ST ideal for truckload fleets.
The ISX 485 ST is designed for the premium truckload market and will be available in the traditional straight rating, or the new SmartTorque rating.
Each of the new horsepower ratings will be compatible with a wide variety of transmissions.
Meanwhile, the Cummins ISM heavy-duty engine will boast improved fuel economy, the company says, as well as 410- and 425-horsepower ratings. Both the ’07 ISM and ISX powerplants will be available in limited production in the fourth quarter of 2006, with full production scheduled to commence in the first quarter of ’07.
