Commercially produced aerodynamic pickup bed cap   Commercially produced aerodynamic pickup bed cap
Brett Herndon is a genuine craftsman who has combined his skill in clay modeling with his knowledge of aerodynamics to produce a professional quality aerodynamic truck cap which will literally pay for itself in gas savings. It's unlike anything you've seen before: it can be used as a big hatchback, transformed into a conventional box cap, or have its top removed to make room for oversize loads. Brett is taking his handiwork into commercial production, and is a success story waiting to happen.

Honda Insight Tail Extension Project   Honda Insight Tail Extension Project
What happens when you start with one of the most aerodynamic production cars ever sold and add a custom-crafted tail to make it even more efficient? Initial testing showed an improvement in fuel economy of 10.3% at 56 mph, or tentatively around an 18% reduction in aero drag. With this tail and other aero modifications in place, the car is regularly returning 100+ MPG tanks in every day use in warm weather.

Manual vs. automatic transmission MPG showdown: Nissan Micra 1.6L   Manual vs. automatic transmission MPG showdown: Nissan Micra 1.6L
The Micra's official ratings are almost the same for the automatic and manual transmission. Yet the 5-speed can be much more efficient in the real world using just one simple ecodriving technique. Again we see the EPA handicaps manual transmission cars due to dictated, non-eco shift points during testing.
