Peterbilt promos 2013 PACCAR engine lineup

By Jack Roberts on

Peterbilt Motors Company announced today the availability of the next generation of PACCAR engines, developed to meet the Environmental Protection Agency’s (EPA) 2013 emissions requirements. Peterbilt says PACCAR MX-13, PACCAR PX-9 and PACCAR PX-7 engines are designed to maximize fuel efficiency, reliability and provide a low total cost of ownership. The PACCAR engine lineup will be available in Peterbilt’s complete range of Medium and Heavy Duty products beginning in 2013.

“The integration of PACCAR engines into Peterbilt vehicles provides an outstanding solution to our customer’s operational needs,” said Bill Kozek, Peterbilt General Manager and PACCAR Vice President. “The new PACCAR engines were developed to combine increased fuel economy with industry leading reliability, resulting in maximum operating efficiency.”

PACCAR MX-13
Peterbilt says the 12.9-liter PACCAR MX-13 engine is characterized by its combination of proven technologies and a large number of state-of-the-art innovations that improve fuel economy. The PACCAR MX-13 engine is designed to meet the demands of heavy-duty truck applications in both vocational trucks and on-highway tractors. It’s available in a wide range of horsepower ratings starting at 380 with torque offerings up to 1,450 pounds.

Additional PACCAR MX-13 engine enhancements include a common rail fuel system that maintains injection pressures of 2,500 bar, providing improved efficiency. The result is finer fuel atomization and more ways to optimize combustion, ensuring the lowest possible fuel consumption, emission and noise levels.

“The advanced engine software, sensors and actuators also play an important role in this respect, functioning faster with increased precision to ensure that the best possible mixture of air, fuel and exhaust gases are used at all times,” said Landon Sproull, Peterbilt Chief Engineer. “Our testing indicates significant fuel economy improvements that will further improve operational costs for our customers.”

The PACCAR MX-13 is available in Peterbilt’s all new Model 579 as well as Peterbilt’s aerodynamic Models 587, 386 and 384, as well as its traditional and vocational line-up that includes the Models 389, 388, 367 and 365.

PACCAR PX-9

Peterbilt touts the 8.9-liter PACCAR PX-9 engine has one of the highest power-to-weight ratios in its class, with heavy-duty features like replaceable wet liners, roller cam followers, bypass oil filtration and targeted piston-cooling. The 8.9-liter PACCAR PX-9 engine is available in both medium and heavy- duty configurations with horsepower ratings from 260 to 380hp and provides up to 1,250 lb/ft. of torque.

The PX-9 is available in Peterbilt’s regional haul Model 382, speciality application market Model 348, and the Model 320, a low cab forward vehicle specializing in refuse markets.

PACCAR PX-7

According to Peterbilt, the 6.7-liter PACCAR PX-7 engine delivers superior performance, minimizes operational costs and maximizes uptime for medium-duty customers. The PACCAR PX-7 is available in horsepower ratings from 200 to 325hp and offers up to 750 lb/ft. of torque.

The PX-7 is available in Peterbilt’s entire medium duty product line including Models 330, 325, and Models 210 / 220, which the company says are ideal for pickup and delivery, towing, refrigerated van, roll- off and landscaping applications.
