Peterbilt trucks powered by a 2017 PACCAR MX engine will provide customers new horsepower and torque ratings, higher performance, and lower cost of ownership, according to Peterbilt Motors Company.

The 12.9-liter PACCAR MX-13 engine is now available with up to 510 horsepower and 1850 lb-ft of torque. The 10.8-liter MX-11 engine is available with a new 335 hp and 1150 lb-ft torque rating. The PACCAR MX engines achieve peak torque at 900 RPM for the majority of engine ratings.

Both the 2017 PACCAR MX-13 and MX-11 include a new single-cylinder air compressor, variable displacement pump, and variable speed coolant pump. Peterbilt says the new designs improve fuel economy and extend service intervals for more uptime and lower maintenance costs.

Peterbilt says PACCAR MX engines are designed with an industry-leading B10 life of one million miles, meaning 90 percent of the engines are expected to reach one million miles without the need for a major overhaul.

All Peterbilt diesel trucks—Class 5 through 8—will be configured with an innovative single-canister aftertreatment system that improves serviceability, extends service intervals, and reduces weight by up to 100 pounds. The new system’s compact design allows for a wider range of spec’ing options and configurations to meet additional customer requirements and applications.

Peterbilt has introduced new technology enhancements to its SmartLINQ remote diagnostics platform, as well as expanded availability to all Class 8 truck engines.

SmartLINQ provides customers with real-time, at-a-glance information on fleet health, with detailed diagnostics, and recommended actions, through the web-based PACCAR Solutions portal. SmartLINQ Service Management, powered by Decisiv, will be integrated with the PACCAR Solutions portal in 2017.

Reasoning engine technology, a collective knowledge approach to truck diagnostics and repair, will be integrated with the SmartLINQ platform in December.

“Reasoning engine technology improves truck service and repair efficiencies to get trucks back on the road faster,” said Scott Newhouse, Peterbilt’s chief engineer. “Using actual field repair data, it provides technicians and customers with the most efficient diagnostic and service procedures.”

Every Class 8 truck produced will have a code that dealer service technicians scan to access detailed chassis information and updatable service records though SmartLINQ Service Management. Model year 2007 and newer trucks can be retrofitted with a code through Peterbilt dealerships. The system expedites maintenance and repairs by giving service technicians quick access to essential information to help perform work faster and more efficiently.

Service Management is currently being rolled out to the Peterbilt dealer network. The fleet portal is expected to be available through PACCAR Solutions next summer.

Three phases of improvements to Peterbilt’s Denton, Texas, manufacturing facility are complete and the new building expansion is on schedule to begin operations in January.

The plant improvements include additional east side dock doors for increased receiving capacity, 17,000 square feet of new material receiving area on the west side and an automated storage and retrieval system on the second level of the building for painted hoods, cabs and sleepers.

Earlier this year Peterbilt began construction for a new 102,000 square-foot building on the same grounds just north of the plant. The expansion will provide additional capacity for production and testing. ♦
