Freightliner 114SD, 108SD Heavy Trucks

By Tom Berg, Truck Editor | March 21, 2011

Freightliner has added two models to its line of SD (severe duty) trucks for which it has ambitious marketing plans. The added trucks are a 114SD with a set-back steer axle and a shorter 108SD, also with a setback axle. They join the axle-forward 114SD announced in January

With the Coronado SD which debuted earlier, the SD series represents a commitment by Freightliner’s parent, Daimler Trucks North America, to the vocational market, said Dave Hames, general manager for marketing strategy.  The SDs largely replace models sold by the now discontinued Sterling line.

Unveiled Friday night and Saturday before Conexpo-Con/Agg, the 114SD has a setback steer axle for non-bridge formula states. The 108SD will come only with the setback axle. Both numbers indicate the trucks’ bumper-to-back-of-cab dimension.

The SDs have unique hoods and use steel-reinforced aluminum cabs from the M2 series. Regular, Extended and Crew cabs will be available in all 114SD and 108SD versions.

The 114s will come with Cummins ISC, ISL and Detroit Diesel’s DD13. Soon the Cummins ISL-G natural gas engine will be available. The 108 will come with Cummins ISB and ISC. All engines will use urea fluid exhaust aftertreatment equipment which chemically wipes out oxided of nitrogen while allowing engines to deliver better fuel economy.

All the vocational truck models will have a variety of transmission, axle and chassis options as they go into production later this year.
