‘Supertruck’ big rig design doubles fuel efficiency

By | June 29, 2011, 3:32 AM PDT

Aerodynamic isn’t a word anyone would typically use to describe those hulking behemoths we’ve come to know as big rig trucks. But that may soon change with the introduction of a sleek new exterior design that dramatically cuts emissions and saves fuel.

If standard trucks can be thought of as the four-wheeled workhorses, than tractor-trailers can be likened to modern-day oxen since they’re relied upon to transport some pretty hefty cargo, sometimes with payloads that weigh as much as several hundred tons. And while trucking companies over the years have sought ways to have the vehicles deliver goods by the most cost effective means possible, they’ve primarily focused on improving capacity. A very obvious example of this is the controversial triple tractor trailers that have been banned in some states.

More recent efforts, however, have explored improving the aerodynamics of cargo trucks as a way of saving on the cost of fuel and to meet stricter federal fuel efficiency requirements due to do into effect in 2014.

In February, BMI Corporation employed the Department of Energy’s Oak Ridge National Laboratory resident supercomputer to develop the SmartTruck UnderTray System, a set of finely-tuned wind deflectors that may cut diesel fuel use by of 1.5 billion gallons of diesel fuel and carbon dioxide emissions by 16.4 million tons. Now Jeremy Singley, a design consultant, has come up with SuperTruck, a completely streamlined body kit that, when fitted to existing big rigs, doubles their fuel efficiency.

The kit was designed for AirFlow Truck Company and, at first glance, bears an uncanny resemblance to a high speed rail vehicle. But when you consider that the trains are designed to efficiently transport passengers at speeds of around 200 miles per hour with as little drag as possible, it actually makes a lot sense. What also helps reduce drag is the repositioning of the radiator grill to the bottom of the vehicle so that incoming draft air can flow through with much less resistance.

And apparently, such a radical rethinking of cargo transportation has garnered the attention of some in the trucking business. Singley recently told Wired that AirFlow is negotiating with suppliers to build kits for existing fleets.

Besides the body kit, the company is also looking to take truck aerodynamics a step further by building a big rig from scratch. According to Singley, the proposed vehicle, which is aptly named FutureTruck, has been shown to reduce drag by 63 percent over conventional streamliners.

Several Hundred Tons?
Since most trucks are limited to 80,000 lbs I think saying 40 tons is more accurate. I hate to be on the road with a truck hauling several hundred tons.

UP TO several hundred tons BUT...
In those cases, you wouldn't be traveling at highway speeds so aerodynamics would be a moot point. You'd be going about 20 MPH with police escorts and maybe a flag crew.

This article claims a load of 352 tons was transported by truck...

Great point.
Anything that heavy is not moving fast as seen here with a 350 ton transformer moved a few years ago in New Hampshire.

Yet another solution to a problem that should not exist
The real solution is to move all the cargo back to rail, which has always been more efficient. We need to stop depending on fossil fuels and start looking for real alternatives to our energy needs.

Don't sweat it Tuan...
Some of these guys probably just missed their grammar club meetings this week.

I agree that much of our freight should be moved back to rail and that will inevitably happen to some extent as fuel costs continue to rise. The reason they left in the first place was because of cheap gas (and the fact that trucks can go places that trains cannot).

Also, one more design change that would help make this even better would be to do something about the back of the rig as well. Most people don't realize that when it comes to aerodynamics, the back is just as important as the front. A large flat back creates a vacuum that pulls at the back of the trailer and also creates additional turbulence. A similar but reversed "aero-wedge" at the back would improve efficiency even more.

What is the MPG?
Funny that the article never mentions the mpg rating of the new SuperTruck designs. Statistics and percentages are relatively meaningless in real life. (I believe semi-trucks do something like 4 or 5 miles per gallon?)

Aussie Road Trains
Here is a link to some Road Trains that are used today in Australia. There are 16 photos of some of the rigs on the roads over there. If it can work over there it can work here. I do believe though that it is allowed to help keep prices down in the remote areas.

Interesting........even a little scary.......It doesnt' state what speed restrictions they have (if any). But a person would have to think there would be some.
