Danny Thompson honors father with land speed record at Bonneville

A need for speed runs in the Thompson family at over 400 miles per hour.

Why wheel spats probably won't make a comeback despite aero benefits

Sad news if you were hoping to see fender skirts return to the automotive design mainstream; according to Automotive News, General Motors has already spent a fair chunk of time and money investigating whether or not adding the aero pieces could lead to increased fuel economy.

Chevy Tahoe increases MPGs by dropping the drag

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 whole gallons per mile thing). Every once in awhile we feel bad for overlooking some of t

Questionable Aesthetics: Truck owners get in on the aero ecomods too

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 T100 pickup truck above.

VIDEO: Aerodynamics adds 7 miles to Volt electric range

Back in the spring of 2008 when General Motors took us on a tour of its wind tunnel facility, chief engineer Frank Weber emphasized the importance of aerodynamics in maximizing the electric driving range of the Volt. At that time, all we got see was a one-third scale model covered in various colors of duct tape. However, GM's aerodynamicists, including Nina Tortosa, explained that

Reader provides Photoshop rendering of what production Volt might look like

Over at the Petrozero.org web-site, reader Scott has put his Photoshop skills to work creating a rendering of what the production Chevy Volt might look like. Working from one of the original images of the concept, the shots of the taped up wind tunnel model and what we've been previously told, Scott went to work. You can see the final product as the lower image above which is clearly recognizable as a Volt. Notice that the front axle center line has moved backward relative to the nose of the car

Wal-Mart redesigning its trucks for greater efficiencies

As part of Wal-Mart's program to double the fuel efficiency of its heavy-duty truck fleet in 10 yeas, not only have they just announced that they're investigating dual-mode, diesel-electric drivetrains, but other cutting edge truck technologies may be on the way as well. The Rocky Mountain Institute, who developed the Dane Muldoon
