aerodynamics

South Carolina-based BMI Corporation and the Department of Energy's Oak Ridge National Laboratory have developed a simple set of aerodynamic fairings that reduce fuel consumption of long-haul semi trucks by up to 12 percent. The aerospace-inspired add-ons, which BMI calls the SmartTruck UnderTray ...

BMI Corporation, along with the Department of Energy's Oak Ridge National Laboratory, have developed a set of aerodynamic fairings that are claimed to reduce fuel consumption of long-haul semi trucks by 7-12 percent. The aerodynamic add-ons, which BMI calls the SmartTruck UnderTray System, ...

Aerodynamic performance is getting increasingly important for every new vehicle as automakers strive to improve fuel efficiency and reduce noise. That's especially true for hybrid vehicles as manufacturers aim for MPG ...

Thirty years ago this week, General Motors opened its first full-scale wind-tunnel at its Warren, MI, technical center. Today, the facility is more important than ever. As automakers strive to hit new fuel ...

It's not all that often that SUvs pop up on this site and even less often that one weighing in at nearly three tons graces our pages. Truth is, we rarely have reason to write about these gargantuans. Why? The answer is simple, they aren't usually what we would call green (yes, yes, we know the ...

When most people think of aftermarket suspension components, particularly new springs, it's usually in the context of improving handling. However, performance-oriented suspension components can also have some positive, if unintended, consequences for fuel efficiency. Higher performance springs ...

General Motors' full-size pickup trucks may be next in line to get thermostatically controlled louvers behind the grille to improve aerodynamics. SRG Global, which produces a variety of components for numerous manufacturers, is ...

Years ago, vehicles were smaller and significantly lighter. Now, chock full with a growing list of standard features, vehicles have become overweight beasts on the roadways. It's certainly appealing to many to have all of the amenities of a luxury hotel suite packed into your car or truck, but ...

You might have thought that anyone who's willing to go to the trouble of modifying his ride with questionable exterior modifications in the name of fuel efficiency would start with a small, efficient vehicle in the first place. Apparently, that's not always the case, as can be seen by the Toyota ...

Putting an aerodynamic fairing around a motorcycle or scooter certainly isn't a new concept. Sometimes, though, major efficiency gains aren't as easy to come by as first expected. That's why Dutch efficiency enthusiast Allert Jacobs' successes are so amazing. So far, Jacobs has improved his Honda ...
