Paccar MX-11 engine to be available for vocational, regional haul trucks

The Paccar MX-11Kenworth will begin selling the Paccar MX-11 engine for its vocational and regional haul trucks in the United States and Canada in January 2016.

The recently introduced 11-liter engine is designed to produce up to 430 hp and 1,550 lb-ft of torque.

The 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.”

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