Kenworth Prepares To Roll Out PACCAR MX-11 Engine For Vocational and Regional Haul Customers in 2016

Kenworth will begin selling the PACCAR MX-11 engine to its vocational and regional haul customers in the United States and Canada in January 2016.



Just introduced by PACCAR, the 11-liter engine is designed to produce up to 430 hp and 1,550 lb-ft of torque. It is positioned between the PACCAR PX-9 and MX-13 engines to give Kenworth an expanded range of proprietary engines for its Class 8 product line.

The PACCAR MX-11 engine will be available for the Kenworth T880, T680, T800 with FEPTO, and W900S and will be built at PACCAR’s engine plant in Columbus, Miss.

“The PACCAR MX-11 fits a sweet spot for many of our customers, who need a lighter engine that provides ample horsepower and torque,” said Jason Skoog, Kenworth assistant general manager. “It is 400 pounds lighter than 13-liter engines, and due to the weight savings, provides our customers a boost in payload capacity and fuel economy.”

Skoog said the engine has logged significant testing hours throughout North America and has delivered excellent results. “Drivers are telling us the engine has plenty of low-end power and it’s a great match for applications requiring less than 450 hp. Like all PACCAR engines, the MX-11 was designed for long-life and maximum productivity.”

The PACCAR MX-11 is a six-cylinder, 24-valve design and has double overhead camshafts along with high-pressure common rail fuel injection. Like the PACCAR MX-13, the engine block is constructed from compact graphite iron with vertical ribs to maximize strength while reducing noise levels.

To help serve customers, Kenworth is conducting extensive PACCAR MX-11 training for Kenworth dealer service technicians and salespeople in the United States and Canada as part of its preparations for the PACCAR MX-11 engine launch.

The PACCAR MX-11 is featured in the current Kenworth Road Tour focused on fuel efficiency and weight savings with stops at 28 Kenworth dealer-hosted events in the United States and Canada.
