What Are Some Common Specs of Freightliner Trucks?

Engines that produce high amounts of torque and automatic Allison transmissions are two common specs of Freightliner trucks. As the company produces a wide variety of task-specific vehicles, the exact specs depend on the individual vehicle. The Business Class M2 106 and the 122SD are two vehicles that Freightliner manufactures.

Freightliner offers the Business Class M2 106 in two engine variations: the Cummins ISB or the Cummins ISL9. Able to deliver up to 325 horse power and 750 pounds-feet of torque, the ISB is a 6.7-liter engine that aims to deliver a low cost of operating by optimizing uptime. The engine features a high-pressure common rail fuel system, flexible injection timings and reduced noise. In comparison, the six-cylinder ISL9 produces up to 380 horsepower and 1,300 pounds-feet of torque. It also features roller followers, bypass oil filters and targeted piston cooling.

The company offers the severe duty 122SD with different engines, three of which are DD13, DD16 and Cummins ISX15. Compressing 906 cubic inches of air at a ratio of 18.4:1, the DD13 produces up to 505 horsepower and 1,750 pounds-feet of torque. The six-cylinder DD16 can deliver up to 600 horsepower and 2,050 pounds-feet of torque. Able to produce the exact same performance as the DD16, the Cummins ISX15 is a six-cylinder engine that features fully-integrated electronic controls, an XPI fuel system and a Cummins VGT turbocharger.
