At 13.4 mpg, the future of aero trucking?

AirFlow’s BulletTruck prototype

Aerodynamics is getting more attention these days now that diesel has risen fairly steadily for about four months to top $4. You can read a lot more about it in the November Overdrive, where columnist Kevin Rutherford will examine the aero trailer benefits for owner-operators. Also in that issue, our fuel-saving tips list will devote a big section to aero features.


Those who attended the Mid-America Trucking Show this year got a glimpse of aero’s possible future if they stopped by the AirFlow Truck Co. exhibit. The company’s website also has plenty of info on what they’ve done and are trying to do.


Most impressive is the results from a test run from Connecticut to California in June. AirFlow says its BulletTruck prototype averaged 13.4 miles per gallon. The website documents the effort and has good shots of the truck, which was originally a 2003 Kenworth T2000. It’s powered by a Cummins 15-liter ISX, with 450 hp and 1,450 ft.-lb. of torque, writes AirFlow President Bob Sliwa. Gross vehicle weight for the test run, which included actual deliveries, was 65,000 pounds and below.


“If we get the investors, we intend to build AirFlow Trucks from scratch and sell them in the (hopefully) near future,” Sliwa says. He points to the 2015 concept vehicle, which will be similar to the cross-country test model.

    13.4? It’s BS! They just want sell this piece of equipment, aero dynamic of the truck didn’t play much on mpg, I learn it from my own experience. Hope not much people so stuiped to buy this thing. Btw I saw this truck, looks ugly…

    yeah,it received bad review on the road, like dildoe mobile.ect.

    It may be fine for over the road but no amount of aerodynamics is going to help fuel mileage from constantly starting and stopping in town.

    This isn’t BS, there is a guy with a Cascadia Evo that gets 10. He runs 60 and has only did a few mods on the Freightshaker to get it.

    I subscribe to the school of thought that says everything counts. Even if aerodynamic design isn’t the final answer, it will help. Think about it. Even high speed trains are designed more aerodynamically than the slower freight trains.

    Actually I think the whole idea is for open road.

    I like it.

    Judging by the lack of English skills I’m willing to bet your science skills are not very advanced either.
