Paccar is expanding its range of diesels in North America with the introduction of the 10.8-liter MX-11, based on a successful model in Europe.

The new engine weighs about 400 pounds less than the larger MX-13, and has six ratings from 355 to 430 hp with torque of 1,250 to 1,550 lb-ft., the company said.

Paccar launched its MX-11 in Europe in 2013, installing over 10,000 of them in DAF trucks in the last two years. Field testing has covered 2 million miles.

“The Paccar MX-11 engine is designed to deliver optimum performance and fuel economy, industry-leading durability and reliability, and a quiet operating environment for the driver,” said Landon Sproull, assistant vice president.  

The engine combines state-of-the-art innovations and proven technologies that reduce weight and deliver features needed for a wide variety of over-the-road and vocational applications, Sproul said.  It has double overhead camshafts and a common rail fuel system with injection pressures of 36,000 psi.

It uses compacted graphite iron in its cylinder block and head, and claims a B10 life of 1 million miles for highway applications and 750,000 for vocational use. That means 90% of the engines will still be running at those points with little maintenance.

The new engine will be available in Kenworth and Peterbilt trucks and tractors in January.
