Peterbilt News P eterbilt Motors Company has announced the availability of the highly anticipated new PACCAR MX ™ engine for Class 8 vehicles, delivering design excellence and industry leading per- formance, 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, providing best-in-class performance through engineering and vehicle op- timization. "The PACCAR MX leverages the corporation's 50+ years of engine development and manufacturing expertise, over 50 million test miles along with the over 125,000 PACCAR MX engines operating globally," says Bill Jackson, Peterbilt Gen- eral Manager and PACCAR Vice President. "The PACCAR MX takes our trucks to the next level of integration and optimi- zation, 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. 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 Se- lective Catalytic Reduction (SCR) in combination with exhaust gas recirculation (EGR) to meet the EPA 2010 diesel engine emissions regulations. CGI block 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.
