NAPA VALLEY, Cali. — Freightliner, in its ongoing quest to control the vocational truck market, has added new options to its M2 and SD truck models.

“We are dedicated to providing our vocational customers with a breadth of options that contribute to durability and benefit on-the-job performance,” said Mary Aufdemberg, director of product marketing for Freightliner Trucks.

New options on the M2 and SD include:

• Hood-mounted mirrors for the 108SD and 114SD
• A new rock guard for the 108SD and 114SD
• Remote start/stop for the M2 106, M2 112, 108SD and 114SD with manual transmissions
• Watson & Chalin lift axle suspensions on all SD models
• Hendrickson AeroClad 12-inch logger-style bumper on the 122 SD

Also, Freightliner announced availability of the Cummins Westport ISX12 G heavy-duty natural gas engine as a factory-installed option on the Freightliner 114SD severe-duty truck, beginning in 2015.

The company says the nat-gas engine will be a good fit for mixer, crane and sewer-vac applications. The engine can be had with up to 400 hp and 1,450 lb.-ft. of torque, and can be run on either compressed or liquefied natural gas.

“The 114SD, when paired with the Cummins Westport ISX12 G heavy-duty natural gas engine, will provide our vocational customers with another green option for their toughest jobs,” said Aufdemberg. “Our entire natural gas product line – from the 114SD to the M2 112 and Cascadia113 – is not only environmentally-friendly, but durable, productive and powerful.”
