KIRKLAND, Wash. — Truckers and fleets seeking to operate a truck with 625 horsepower can now order the Caterpillar C15 engine in 625 and 600 horsepower ratings in Kenworth’s classic W900L long-nose conventional.

"Kenworth is pleased to offer the new Caterpillar C15 high-horsepower engine in our Kenworth W900L model to help provide the power needed by customers to get the job done,"said Steve Gilligan, Kenworth’s general marketing manager. "Owner-operators and heavy haulers will especially be interested in these new Caterpillar’s products available this fall."

Caterpillar’s 625 hp C15 provides 2,050 lb.-ft. of torque at 1,200 rpm and constant torque to 1,500 rpm. Maximum 625 hp is developed at 1,800 rpm with 595 hp at 2,100 rpm. The new product is built on a proven Cat engine platform with the same bore and stroke as the 550 hp C15. Advances include new pistons and injectors for the higher flow series turbochargers, and the next generation Caterpillar electronic control module that is four times faster with twice the memory than the previous C15 ECM.

Caterpillar’s new 600 hp rated C15 has 1,850 lb.-ft. of torque at 1,200 rpm and is an ideal option for owner-operators and heavy haulers who want high horsepower with a lower cost driveline.

Kenworth is also offering an optional Caterpillar compression brake, which is the only compression brake available for these engines, added Gilligan. The Cat compression brake provides 600 retarding horsepower.
