Paccar MX-11 ENGINE

Paccar releases their first lightweight, fuel-efficient engine.

With fanfare and excitement Peterbilt’s first lightweight, fuel-efficient production PACCAR MX-11 engine was recently installed in the company’s newest vocational truck, the Model 567, in a set-forward front axle configuration. The engine, which has been available in European markets for a few years but has made its first official appearance stateside, is said to be fuel-efficient without sacrificing power.

The PACCAR MX-11 engine is the newest addition to the Peterbilt catalog and the second option in Paccar’s MX lineup, joining the MX-13, which has already sold over 100,000 units. The PACCAR MX-11 engine is characterized by its combination of proven technologies and state-of-the-art innovations. It’s optimized for integration with Peterbilt’s aerodynamic Model 579 and vocational Model 567 trucks. The PACCAR MX-11 provides outstanding value in its design – exceeding both Peterbilt’s high standards and customer expectations.

“The PACCAR MX-11 will bring new levels of performance, durability, reliability and overall return for customers,” said Robert Woodall, Peterbilt Assistant General Manager of Sales and Marketing.
“It is lightweight and fuel efficient, making it an ideal power choice for customers in a wide range of applications, including regional haul, tanker, bulk haul, construction and refuse.”

PACCAR engines are designed for optimized heavy-duty performance in Kenworth, Peterbilt, and DAF Trucks. The technologically advanced PACCAR MX-11 engine is designed and manufactured to deliver not only the highest levels of quality and performance, but also reliability, durability, and greater overall return on investment.

The innovative design of the 10.8-liter PACCAR MX-11 engine is equipped to meet the demands of the industry. The engine also hits the sweet spot for many customers who need a lighter engine that still provides ample horsepower and torque. The PACCAR MX-11 features an outstanding power-to-weight ratio, clocking in at 400 pounds lighter than other 13-liter engines while providing customers both a boost in payload capacity and fuel efficiency.

The sophisticated calibration of the common rail fuel system with high injection pressures of 2,500 bar, optimize combustion for low fuel consumption, low emissions, and reduced noise levels as well. Drivers will appreciate the responsiveness, performance, and quiet operation of the PACCAR MX-11 engine running in their Peterbilt trucks. The rear-mounted gear train and floating oil pan both help reduce engine vibrations and noise, providing drivers with a quieter operating environment and smoother ride.

The MX-11 engine also has an output of 355 to 430 horsepower with torque ratings ranging from 1,250 to 1,550 lbs per ft. It also has six inline cylinders and a double overhead camshaft design and is the only commercial diesel engine to use Compacted Graphite Iron (CGI) in both the engine block and cylinder head. CGI is roughly 20 percent lighter and 75 percent stronger than traditional gray iron, making the MX-11 a lightweight and more durable alternative to comparable Cummins ISX12 or PACCAR MX-13 engines.

With an industry-leading B10 life of one million miles, engineers have planned for the future and designed the engine to allow quick updates with new software the ability to be programmed to meet specific customer requirements so owners can keep their vehicles for years to come.

The engine will be produced at PACCAR’s Columbus, MS engine manufacturing plant, a 450,000 square foot facility opened in 2010, where the MX-13 engine is also produced. In a recent PACCAR press release, Darrin Siver, Peterbilt General Manager and PACCAR Vice President, shared his assurance of the superior manufacturing facility.

“PACCAR’s investment in its North American engine facility has ensured it is the most modern, technologically advanced and highest quality engine manufacturing plant in the world,” he stated. “A highly skilled and well-trained workforce, complemented by cutting-edge robotics and automation, ensure PACCAR engines are of the highest reliability, durability, and quality.”

With over 50 years of engine development and manufacturing expertise behind it, PACCAR has created a revolutionary engine that meets the needs of a wide variety of over the road and vocational applications. Now that PACCAR has launched their MX-11 engine in North America, the powerful, lightweight engine is available in DAF, Kenworth, and Peterbilt trucks. If the award-winning PACCAR MX-13 engine tells us anything, it’s that the MX-11 is sure to be a smash hit in the states.
