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.

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.
