PACCAR Launches New Proprietary Axles and Engine Enhancements

PACCAR is launching a new proprietary tandem axle that is the industry’s lightest and most efficient axle in its class. “PACCAR is pleased to deliver the most fuel efficient axle in the industry to complement the superior performance and fuel economy of our PACCAR MX Engines” said Landon Sproull, PACCAR vice president.

The new PACCAR axle is designed to improve the operating efficiency for line haul, regional haul and pick-up and delivery customers. The new axle is rated at 40,000 pounds, supporting a gross combination weight of 80,000 lbs. Kenworth and Peterbilt will begin offering the axle to customers in January 2017. “PACCAR’s axle reduces vehicle weight by up to 150 pounds, and provides improved fuel economy,” noted Sproull.

The PACCAR axle features a unique pinion-through-shaft design that simplifies power flow in the axle for maximum efficiency. The PACCAR axle also incorporates an innovative laser-welded carrier design that reduces weight and improves fuel economy. The PACCAR axle comes with an industry-leading warranty of five years or 750,000 miles.

The PACCAR axle offers ratios from 2.47 to 3.70 with engine torque compatibility up to 1,650 ft.-lb. and multi-torque rating compatibility up to 1,750 ft.-lb.

PACCAR Introduces Enhancements to MX-13 and MX-11 Engines

The new engines will be available in Kenworth and Peterbilt trucks in January 2017. “The PACCAR MX-13 and MX-11 engines are designed to deliver optimum performance, durability, fuel economy, and the lowest total cost of ownership for our customers.” said Landon Sproull, PACCAR vice president.

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.

PACCAR designs MX engines to an industry-leading B10 life of one million miles. This means 90% of the PACCAR MX-13 and MX-11 engines are expected to reach one million miles without the need for a major overhaul. Each PACCAR MX engine also comes standard with factory installed remote diagnostics to deliver proactive customer support. This translates into low cost of ownership and superior uptime for truck owners.

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, a significant cost savings for customers over the life of the vehicle. PACCAR MX-13 and MX-11 engines now utilize a single canister aftertreatment system that reduces weight by 100 lbs, improves serviceability and lengthens service intervals.

PACCAR is one of the leading diesel engine manufacturers in the world with the design, manufacture and production of 1.4 million PACCAR engines globally since 1957. “PACCAR will have 135,000 PACCAR MX engines in operation in North America by year end. Nearly 50 percent of Kenworth and Peterbilt trucks delivered to customers in North America this year will be powered by a PACCAR MX engine,” said Sproull. “This strong adoption level is a testament to the outstanding performance, durability, fuel economy and low cost of service delivered by the PACCAR MX-13 and MX-11 engines
