Freightliner Custom Chassis Corp. is completing final testing of pre-production S2G propane autogas trucks and expects to begin production of the vehicle in the summer, according to a company spokesperson.

Freightliner, which introduced the front-engine truck at the 2013 NTEA Work Truck Show, has built 25 pre-production S2G trucks so far. The company is now evaluating the systems of four test vehicles.

"Once we've reached a level of confidence with these four test vehicles, we will being delivering the field test units to assigned customers," according to Freightliner. "Our expectation is to revue real-world, operational and positive feedback from end users. When we do, we will then schedule regular production and begin taking orders."

The S2G will offer an 8.0L dedicated propane autogas engine that generates 339 hp and 495 lb.-ft. of torque, mated to an Allison 2300 automatic transmission. Gross vehicle weight will come in at 33,000 pounds.

The S2G utilizes the Freightliner M2 cab, which features a sloped, forward-tilting hood for improved visibility and engine access.

    I JUST STARTED DRIVING THE NEW FREIGHTLINER PROPANE TRUCK, AND MY QUESTION IS: WHY IS THE GAS MILEAGE SO TERRIBLE?? I FILLED THE TANK THIS MORNING BEFORE I HIT THE ROAD, AND HAD TO FILL IT AGAIN THIS AFTERNOON WHEN THE FILL LIGHT STARTED BLINKING. ONLY GOT 192 MILES OUT OF A FULL TANK. IS THIS THE MAXIMUM??

    We bought 2 of these trucks and one of them has failed w less than 200 miles on the clock. A full week later at San Diego Freightliner and they are still "diagnosing" it. Very difficult to reach anyone on this issue locally or in South Carolina. NOT a happy customer so far.

    We have 2 new 2SG's and each use a considerable amount of motor oil
    is anyone else having this issue

    There is noticeable oil usage with the 2 we purchased. But if they are like the 8.1 motors then the dip stick reading is off a little. You will find a sweet spot on the stick where it won't use anymore.

    The transmission electronic sensor is an issue and stops the S2G from climbing driveways in forward or reverse. Apparently they are calibrated to prevent grades beyond a certain percentage. The 8.1 GM chassis climbs everything. But the S2G stalls on fairly small grade driveways. It's an issue with the 2800 gallon bottle and the 3000 gallon bottle. One would expect the weight of the 3000 gallon bottle to be possible but why would it be the same for the 2800 gallon bottle? To me it seems the sensor is measuring faulty info.
