LOUISVILLE, KY – Cummins Inc. has released its most powerful ISX in years, with 600 horsepower and 2050 lb.-ft. of torque. This new rating is designed for heavy-haul customers, fleets, and owner/operators who specialize in expedited freight. Extra torque allows drivers to maintain road speed even on steep inclines, reducing the number of downshifts and fuel consumption. Maintaining a higher average road speed with less shifting also reduces driver fatigue and shortens trip time. 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 U.S. in Jamestown, New York, the Cummins ISX remains the only Heavy-Duty diesel engine built with dual overhead camshafts and an integrated engine brake as standard equipment. The ISX 600 with 2,050 lb.-ft. peak toque is scheduled to become available in the fall of 2007.
