Cummins announces 2007 heavy-duty ratings for the ISX and ISM

Cummins Inc. announced at the Mid-America Trucking Show the '07 ratings for its heavy-duty ISX and ISM engines. With more than 30 billion miles of proven cooled-EGR experience, the 2007 ISX and ISM build on the proven performance, reliability and durability of today's heavy-duty engines.

A full lineup of ratings will be available for the '07 ISX and ISM. Three new ratings for the 2007 ISX were introduced at MATS this week:

  • ISX 425 SmartTorque (ST);
  • ISX 485 ST; and
  • ISX 600.

Leveraging core in-house technologies from Cummins air-handling to aftertreatment enables the 2007 ISX to meet the demands of every customer - from truckload fleets to owner-operators. The ISX delivers the fuel economy, low operating cost, and performance and durability that the trucking industry expects.

The ISX 425 SmartTorque provides extra torque - 1550/1750 lbs.-ft. of extra torque. This higher-operating torque level will allow drivers to stay in top gear longer, maintain road speed better and shift less often on grades. This unique SmartTorque rating will increase the percentage of time in top gear along with providing increased driver satisfaction. Increased time in top gear and less shifting mean better fuel economy. The ISX 425 ST rating will be ideally suited for truckload fleets.

The ISX 485 ST is designed for the Premium Truckload market. Customers will have a choice of either a straight rating or a SmartTorque rating. The ISX 485 ST delivers on the performance and fuel economy needs of these customers.

For owner-operators, Cummins will offer the ISX 600 with 1850 lbs.-ft. of torque. This will be the ideal rating for heavy haulers and owner-operators who demand extra performance.

All of the new ratings are compatible with a range of automated and manual transmissions. Customers selecting the ISX 425 SmartTorque will have options for selecting various transmissions to optimize for best operating efficiency in their specific fleet. The ISX 425 SmartTorque is ideally suited for both direct and overdrive transmissions.

According to Jeff Jones, Cummins' vice president for sales and market communications said, "We continue to expand our ratings to deliver every advantage for our customers. These additional ratings hit the sweet spot for two very important but different sets of Cummins customers, with specific advantages for the needs of their very different business models. Those involved in truckload operations where the absolute best fuel economy makes the difference in business performance, and those who need extra horsepower for demanding loads."

These ratings are enabled by a combination of Cummins proven engine technologies, including enhancements to Cummins cooled exhaust gas recirculation, combined with high injection pressures, the ability of the Cummins particulate filter to maximize use of passive regeneration, the Holset VG turbocharger with electric actuation, plus integrated engine and aftertreatment controls.

The new ISM heavy-duty engine will also feature enhanced fuel economy for 2007 and will include 410 and 425V horsepower ratings. The ISX and ISM will use proven Cummins emissions reduction technology to meet the U.S. Environmental Protection Agency and California Air Resources Board emissions standards for 2007.

Both the ISX and ISM for 2007 will be available in limited production in fourth-quarter 2006, with full production beginning in January 2007.
