The Freightliner 114SD is the evil brother of the already rugged 108SD model. Compared to its smaller brother, the 114SD is stronger and more capable, having a maximum GVW (gross vehicle weight) rating of up to 91.000 lbs.
The truck is available with a wide range of engines including the Detroit DD13, Cummins ISC, ISL and the efficient ISL-G units. The company says that the 108SD has been put through rigorous testing to make it one of the most performant and reliable trucks in its class and judging by the positive market response they are not far from the truth. The truck is priced around $120,000 and is available in Day Cab, Extended Cab and Crew Cab configurations.
Except for a few small differences, the exterior design of the 114SD is similar with the 108SD. The truck features a huge trapezoidal radiator grille traversed by five horizontal stripes painted in black paint. The grille is surrounded by a shiny border and bares the Freightliner’s logo at the top.
The light clusters are a bigger and shinier than those from the 108SD, and the 114D also features a vertical exhaust pipe mounted behind the cabin which gives it a purposeful look.
The Freightliner 114SD is offered with a strong single-channel rail with 120k of tensile strength. Optional frame inner and outer rail liners are also available for tougher jobs.
The cabin is build using steel-reinforced aluminum and was highly tested to offer maximum safety in case of accidents. Moreover, the vocational chassis backbone is available with both single and double channel frame rails for enhanced performances. If needed, the truck can be equipped with an optional heavy-duty center tow pin mounted on the bumper which has a towing capacity of up to 80,000 lbs.
Like the 108D, the 114SD is also available with Freightliner’s SmartPlex Electrical System which provides a high level of flexibility for Truck Equipment Manufacturers when configuring the truck to suit specific body installations.
Once you’ll hop inside you’ll probably won’t be surprised to find a similar looking cabin with the 108SD model. Sadly the dated look persists and you’ll also find the same rock hard plastics and poor materials. On the other hand, we are sitting in a working truck so we get an interior that suits its utilitarian nature. The fittings however, look better than what you’ll get from Peterbilt or Kenworth and the overall ergonomy is also pretty good with an uncluttered dashboard and logically placed controls.
The wing dashboard is also pretty easy to live with and we like the big LED-backlit gauges fitted into the instrument cluster, as they are easy to read and don’t distract your attention from the road.
The seats aren’t the most comfortable in the business and they aren’t even fitted with headrests, but they have plenty adjustments which help you to find an adequate driving position without too many efforts. The steering wheels keeps the same utilitarian design found all over the cabin and its big dimensions make it difficult to handle. The good part is that it can be adjusted for both reach and rake and also folds out of the way permitting you to get in and out of the truck pretty easy.
Thanks to the high driving position, the 2,500 square-inch windshield and the downward sloping cab hood the straight road visibility is outstanding. On the other hand, the storage department is pretty poor represented and apart from a big bottle holder mounted into the dash, a glove box and the door pockets there aren’t other significant storage boxes to put your things.
Engines and performance
The Freightliner 114SD is available with a plethora of engines including the Detroit DD13, Cummins ISL-G, Cummins ISC and Cummins ISL units.
The Detroit DD13 features the BlueTec emissions technology and develops 350 HP and 1,350 lb-ft of torque. The engine offers a strong bottom end torque and is able to toe huge payloads without breaking a sweat.
The Cummins ISL-G unit offers the advantages of clean-burning natural gas without sacrificing power or torque. The engine delivers lower emissions, improved performance and lower costs, being perfectly suited for those seeking for environmentally friendly solutions for their vocational trucks.
The Cummins ISC 8.3 engine is the same found at the Freightliner108SD and is already famous for its high power-to-weight ratios, being designed to offer strong performances at low rpms.
The Cummins ISL9 features replaceable wet liners, XPI fuel system and an improved Electronic Control Module (ECM) along with enhanced airflow developing a maximum output of 380 hp with 1300 lb-ft of torque.
The engines can be mated on either Eaton Fuller 10-speed manual gearboxes or Allison automated transmissions.
For the Cummins engines the truck is also available with the selective catalytic reduction (SCR) after treatment system that reduces particulate emissions to meet EPA’s 2010 regulations. Requiring only a few tweaks under the hood, the SCR system offers less stress for the engine, and improved fuel economy.
For enhanced versatility, the Freightliner 114SD is offered with front engine, rear engine and transmission power take-off (PTO) options for a wide range of applications.

Ride and handling
The cab is air suspended, which means that the ride is pretty forgivable and only the biggest bumps are transferred inside. The Freightliner is available with Hendrickson walking beam and air ride, or Freightliner’s AirLiner and TufTrac suspensions which can deal with huge payloads without baking down.
The truck’s steering is light and responsive and despite its lack of road feedback it helps you to control this big rig without any problems. The Freightliner 114SD is also pretty easy to drive in tight situations thanks to its small turning radius and to the 50 degree wheel cut which further enhances the maneuverability.
The Freightliner 114SD gives to the words “severe duty” a new meaning. The truck is strongly build and is fitted with a bunch of powerful, reliable and efficient engines which offer class leading performances.
The chassis is can also be compared with the toughest units in the segment, while the truck’s tight turning radius and the 50 degree wheel cut makes it easy to maneuver around city. Its interior however is a bit dated and the price tag is also a bit too expensive compared to other trucks in the segment.
