PACCAR launched new power, torque, and fuel-efficiency enhancements to its MX-13 and MX-11 engines for North America. The new engines will be available in Kenworth and Peterbilt trucks in January 2017.

PACCAR increased the MX-13 engine’s output to 510 hp and 1,850 lb.-ft. of torque and increased the MX-11 engine’s output to 430 hp and 1,650 lb.-ft. of torque. The enhanced PACCAR MX-11 engine also adds a new 335 hp and 1,150 lb.-ft. torque rating in the lower end of the power range. PACCAR’s MX engines deliver peak torque at 900 RPM for the majority of engine ratings, supporting increased performance and driving flexibility, according to the engine maker. 

PACCAR designs MX engines to a B10 life of 1 million miles, in other words, 90% of the PACCAR MX-13 and MX-11 engines are expected to reach 1 million miles without the need for a major overhaul, according to PACCAR. Each PACCAR MX engine also comes standard with factory-installed remote diagnostics to deliver proactive customer support.

The 2017 PACCAR MX-13 and MX-11 engines include a new single cylinder air compressor, variable displacement oil pump, and variable speed coolant pump providing customers with fuel economy gains over the previous engine design. The latest PACCAR MX-13 and MX-11 engines extend oil and fuel filter change intervals from 60,000 miles to 75,000 miles.

PACCAR MX-13 and MX-11 engines now utilize a single canister aftertreatment system that reduces weight by 100 pounds, improves serviceability and lengthens service intervals.
