While KITT isn't going to have turbo boost, we still need to do what we can to reduce his wind resistance. Just like any performance car, an EV should have at least a few aerodynamic improvements. The only difference is our goal is to increase range, not speed.

According to Wikipedia, the drag coefficient of an '82 Trans Am is about 0.34. Firebird Fever says that a 1985 Trans Am has a  drag coefficient of ".32 but capable of .29 with standard Aero wheels over the High-Tech turbo aluminums. At the time it was the most aerodynamic car GM ever produced."

The lower the number, the more aerodynamic the car is. The EV1 is the most aerodynamic production car ever made, but some hybrids such as the Toyota Prius and Honda Insight are not far behind (the Wikipedia article is pretty interesting if you want to see how different cars compare.) We can use what we learn from them to make improvements to KITT. I also found a few articles on the EcoModder forum that could prove useful: 65+ Vehicle modifications for better fuel economy and Aerocivic - how to drop your Cd from 0.31 to 0.17

Keep in mind that KITT is going to be a Knight Rider replica, so we also want to keep him looking as authentic as possible. We aren't going to be implementing all 65+ modifications, or making drastic changes like Aerocivic. Instead we're going to make just a few adjustments to reduce the drag a little bit. Are they going to have a big impact on range? Not really, but every little bit helps.
