Today, Peterbilt Motors Company announced the availability of the highly anticipated new PACCAR MX engine for Class 8 vehicles at their press conference at the Mid-America Trucking Show. The PACCAR MX engine delivers design excellence and industry leading performance, reliability and fuel efficiency for Peterbilt’s Vocational and On-Highway lineup.
Beginning in summer 2010, the PACCAR MX will be available in Peterbilt Models 587, 388, 386, 384, 367 and 365. The PACCAR MX was designed, developed and tested to provide best-in-class performance for Peterbilt Class 8 vehicles through thorough engineering and vehicle optimization.
“The PACCAR MX leverages the corporation’s 50+ years of engine development and manufacturing expertise, over 50 million test miles and the over 125,000 PACCAR MX engines operating globally,” said Bill Jackson, Peterbilt General Manager and PACCAR Vice President. “The PACCAR MX takes our trucks to the next level of integration and optimization and the high degree of performance is synonymous with the Class and quality the industry has come to expect from Peterbilt.”
The PACCAR MX engine is available with a horsepower range of 380hp-485hp and torque outputs up to 1,750 lb-ft with a displacement of 12.9 liters. This power range, combined with excellent fuel efficiency, high reliability, durability, lightweight design and low cost of ownership makes it an ideal choice for both over-the-road and vocational applications. The PACCAR MX engine uses Selective Catalytic Reduction (SCR) in combination with exhaust gas recirculation (EGR) to meet the EPA 2010 diesel engine emissions regulations.
The PACCAR MX is the only commercial diesel engine to use Compacted Graphite Iron (CGI) in both the cylinder block and head. CGI is 20 percent lighter and 75 percent stronger than traditional gray iron. Additionally, the engine utilizes fractured cap technology in both the connecting rods and main bearing caps to provide high shearing strength that result in a wide horsepower range and longer torque and power curves for more efficient operation.
“Proper truck specification and component integration is critical in maximizing vehicle power and efficiency. The 2010 PACCAR MX provides the engineered optimal set of technologies that are specially designed to increase fuel economy and add savings to our customers’ bottom line,” said Landon Sproull, Peterbilt Chief Engineer. “Pairing Peterbilt’s proven aerodynamics with technologies, such as electronically controlled high pressure fuel injection, delivers unparalleled fuel economy and unmatched overall performance.”
Customer optimization can be achieved through PACCAR’s PROSPECTOR® sales specification tool which analyzes the application, intended use, payload, fuel efficiency and other factors to determine a best spec for each customer’s application.
“All Peterbilt dealers across the USA and Canada are able to target a customer’s best spec using PACCAR’s PROSPECTOR® to order their ultimate engine performance parameters,” said Arlen Savitt, Peterbilt’s Assistant General Manager of Sales and Marketing. “Peterbilt’s dealer network is ready to welcome customers to experience the PACCAR MX engine’s exceptional power and performance, and all dealer locations have been specially trained in MX sales and service support.”
The PACCAR MX has been designed for ease of maintenance, which results in improved efficiency in dealers’ service facilities. Peterbilt dealers are prepared to provide exceptional parts and service support for the PACCAR MX engine. Peterbilt and all PACCAR dealerships have certified PACCAR MX trained technicians and a complete inventory of service parts. More than 525 authorized service locations across North America are certified in the latest technologies and cutting edge diagnostic tools to service and support the PACCAR Engine family. Additionally, PACCAR operates eight parts distribution centers in North America and provides engine technical support 24/7 – 365 days a year.
