PACCAR MX-11 Engine

KIRKLAND, Wash., Dec. 18, 2015 – The PACCAR MX-11 engine for vocational and regional haul customers is now available for order.

Offered in the Kenworth T880, T680, T800 with FEPTO, and W900S, the PACCAR MX-11 is designed to produce up to 430 hp and 1,550 lb-ft of torque. The 10.8-liter engine is 400 pounds lighter than 13-liter engines and provides customers with enhanced payload capacity and fuel economy. The PACCAR MX-11 is available with a full array of manual, automated manual and automatic transmissions.

“The PACCAR MX-11 is designed for maximum productivity and long life, and has ample low-end power for applications requiring less than 450 horsepower, such as regional haul, tanker, bulk haul, construction and refuse,” said Jason Skoog, Kenworth assistant general manager for sales and marketing. “The addition of the MX-11 broadens Kenworth’s engine offering for Class 8 trucks as it joins the successful, fuel-efficient, PACCAR MX-13 in our lineup.”

The PACCAR MX-11 has a six-cylinder, 24-valve design and dual overhead camshafts along with high-pressure common rail fuel injection. The engine block is constructed from compact graphite iron with vertical ribs to maximize strength while reducing noise levels. The PACCAR MX-11 will be built at the PACCAR engine plant in Columbus, Miss.

PACCAR successfully launched the PACCAR MX-11 engine in Europe in 2013, installing over 10,000 PACCAR MX-11 engines in DAF trucks in the past two years. The PACCAR MX-11 engine has more than 2.5 million miles of field testing in North America and over 250 million miles accumulated in production engines in operation in Europe.
