AirFlow BulletTruck achieves


during a coast-to-coast, real-world, revenue producing freight run!

March 2012

Here is the new AirFlow BulletTruck parked at AirFlow Truck Company World Headquarters in Connecticut.


After the show at MATS, we just completed a 3500 mile shake-down test. A real-world freight hauling run, ranging from freezing temps in the north, to high 90’sF in lower Texas a mile from the Mexican border. Coolant temps averaged 185F and underhood temps averaged 110F. We hauled paper products, Sony electronics, and plastic paint can covers (304,200 of them, to be exact) on real revenue-producing freight runs. Even though we were showcased at the world’s biggest truck show at MATS, this is a not a show truck. It’s a work truck and a test truck.

Here the BulletTruck prototype is parked outside of the Ohio Technical College in downtown Cleveland, Ohio on a goodwill stop.


The OTC has over 1600 students, and all of them are gear-heads. So we felt right at home hanging out with all of those kids for the afternoon.

With so many students enrolled, they came outside in waves to check out the AirFlow BulletTruck rig so they would not overwhelm us and the facility. The groups were based upon their primary area of study, Automotive, Diesel, Body Work, etc.


They asked great questions and we answered them and explained the technology and the fabrication involved in a project such as this.


We also explained how “saving fuel is the new going fast.

We stopped by to see the nice folks at the Cummins Technical Center in Columbus, Indiana after unloading a shipment of freight nearby. In this photo, some of the Cummins engineers are getting their first in-person look at the AirFlow BulletTruck rig.


We have been working long-distance with the engineers at Cummins for years on the BulletTruck via e-mail and telephone calls. They helped us redesign the belt drive system and the cooling system of the ISX. And Cummins has been one of our original Partners since way back in 1983, when we built the first AirFlow rig.

One of the engineers from the Vehicle Integration – Electronics group is shown downloading data from the AirFlow BulletTruck rigs ECM into his laptop. ECM stands for Electronic Control Module, which is the engine computer and the brains of the Cummins ISX engine. The ECM receives data from a multitude of sensors throughout the vehicle, and operates the engine according to this data within design parameters.


We felt honored and privileged to be working inside the Tech Center with all of the Cummins engineers. The access door on this bay had a sign that read:

No Unauthorized Admittance – Customer Engineering
OEM Classified Vehicles Present


Very cool…….

June 2012

We just finished up a coast-to-coast, revenue-producing, real-world, freight hauling run. Nevermind that test-track stuff. Welcome to the real world.


We loaded in Connecticut and our first stop was in Tracy, California. We ran into 35 mph 3/4 headwinds all the way through Wyoming and 40 mph crosswinds traveling through Utah.


But we still achieved an amazing 13.4 mpg average for the entire coast-to-coast trip.

14.3 average MPG from Connecticut to Indiana

Here and below are a couple of images of the BulletTruck high-definition engine display. The first one is from Newington, Connecticut to Gary, Indiana. As you can see in the center top box, we are traveling 56 mph. The upper left corner digits are the current time at 1:39 in the afternoon. We are currently doing 22.4 instant mpg at only 5% engine load which means we are descending slightly downhill. Level and straight with no grade we would be 10% engine load and 17.5-18 mpg. That Instant MPG does not really mean a thing as far as documenting mpg though. It is just feedback tool for the driver. It will display anywhere from 3 mpg to 256 mpg depending if we are going up or downhill. The three numbers in the lower right corner of the display are the key. This is what shows the average mpg for that leg of the trip from Newington, CT to Gary, In. They show 872.2 miles traveled since we reset the readout to zero in Newington. We burned 61.1 gallons from Newington to Gary, which shows as a 14.3 mpg average fuel burn. The average fuel burn is the only one that we are interested in on a leg of a trip.

13.4 average MPG Coast-to-Coast from Connecticut to California

This second display image is right after we got unloaded in Tracy, California. As you can see, we traveled 3043.0 miles coast-to-coast. The lower center 2117.9 is the distance from Gary Indiana to Tracy, California.

So for that 2117.9 miles we consumed 157.8 gallons of fuel for 13.4 mpg average.

That 13.4 average miles per gallon, loaded with freight, is a very amazing MPG number for a coast-to-coast run. The national average fuel consumption for Class 8 trucks in 2012 was only 5.8 MPG.
