New High Performance Engine Rating For Heavy Trucks

Posted on March 21, 2007

Cummins Inc. has announced the release of its most powerful ISX in years, with 600 hp and 2050 lb.ft. of torque. The new rating is designed for heavy-haul customers, fleets and owner/operators that specialize in expedited freight and performance enthusiasts in the trucking industry.

"This rating has been developed to meet growing customer requests for extra pulling power,” Jeff Jones, vice president - Sales and Market Communications. “The fact that we've increased the torque on this engine and maintained exceptional fuel economy while meeting the 2007 emissions regulations with a single diesel particulate filter and turbocharger shows the true benefit of our integrated design and manufacturing capabilities. It is a testimony to the advanced thinking and visionary design of the ISX."

In addition to stronger pulling power, the ISX for 2007 also includes electric actuation on the patented VG Turbo, for improved engine response across the entire power range. The Intebrake system, an integrated compression brake that generates over 600 braking horsepower, continues as standard equipment.

Manufactured in the United States in Jamestown, N.Y., the Cummins ISX engine incorporates dual overhead camshafts and an integrated engine brake as standard equipment. The ISX 600 is scheduled to become available in the fall of 2007, the company said.
