Peterbilt Motors Co. on Wednesday, Feb. 16, announced the availability of the Paccar MX engine with Model 389, providing customers a long-term proposition through its technologically advanced designs and lightweight materials that facilitate added performance and fuel economy.

“High industry acceptance and customer demand has allowed Peterbilt to expand the availability of the Paccar MX engine into the Model 389,” says Bill Jackson, Peterbilt general manager and Paccar vice president. “We are pleased to pair the MX engine with the Model 389, offering customers a superior fuel-economy option that provides longer service intervals, increased uptime, lower operating costs and higher resale value.”

The Paccar MX engine is available with a range of 380-485 hp and torque outputs up to 1,750 lb-ft with a displacement of 12.9 liters. The MX engine uses selective catalytic reduction in combination with exhaust gas recirculation to meet 2010 U.S. Environmental Protection Agency diesel engine emissions regulations. The fully integrated systems with modular components are designed to reduce complexity and lead to longer service intervals, increased uptime and lower operating costs.

Peterbilt and all Paccar dealerships have certified Paccar MX trained technicians and a complete inventory of service parts in-stock. More than 670 authorized service locations across North America are certified in the latest technologies and diagnostic tools to service and support the Paccar Engine family.
