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.

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.
