Kenworth Announces 2010 Engine Offerings for Medium Duty Trucks

ST. LOUIS, Mo., March 11, 2010 – Kenworth Truck Company announced its 2010 engine offering for its medium duty product lineup during a press conference today at The Work Truck Show in St. Louis.  

“The 2010 PACCAR PX-6 and PACCAR PX-8 engines offer enhancements in torque and horsepower options which will provide greater benefits to Kenworth customers in a variety of medium duty applications,” said Jason Skoog, Kenworth director of marketing planning and research.

“Both engines feature a fully integrated electronic control system for increased power density, enhanced reliability and serviceability, and optimized performance.”

The 2010 PACCAR PX-6 and PACCAR PX-8 engines are both available for the Kenworth T270 Class 6 and T370 Class 7 models. The Kenworth T170 Class 5 vehicle is available with the 2010 PACCAR PX-6 engine.

Ratings for the PACCAR PX-6 are 200 to 325-hp with torque from 520 to 750 lb-ft, while the PACCAR PX-8 offers 260 to 350-hp and 660 to 1,000 lb-ft of torque for heavier loads and severe grades. Both engines now feature a high pressure common rail fuel injection system, improved cooled exhaust gas recirculation (EGR), patented variable geometry turbocharger (VGT), and new after-treatment system.

The PACCAR PX-6 series engine, which offers the highest horsepower to weight ratio in the industry, has earned a reputation for low maintenance, high miles per gallon and proven reliability.

For 2010, the PACCAR PX-6 further improves upon low maintenance, fuel economy, proven reliability and durability that add up to superior lifetime value. The durable PACCAR PX-8 contains many features typical of heavy duty engine design, including replaceable wet liners, roller followers, 2-piece steel articulated pistons, by-pass oil filtration and targeted piston cooling.  

For 2010, Kenworth offers three diesel exhaust fluid (DEF) tank options for the medium duty market. Useable DEF capacities are 6.6, 9 and 18 gallons which provide diesel fuel capacities of 110, 150 and 300 gallons, respectively.

Four exhaust options – right-hand (passenger) side under the cab, horizontal, horizontal in-series, and vertical independent – are available for Kenworth medium duty vehicles equipped with the PACCAR PX-6 and PACCAR PX-8 engines.

“Clear back of cab is an important feature for many body installations and Kenworth is proud to have true clear back of cab options for our body builder partners and customers,” noted Skoog.
