I searched a bit in the archives and didn't see any posts but I was wondering what, if any, effect drag coefficient has on a radar and laser gun. Has there been any testing? Example: My Chrysler 300 SRT8 has a cd of .36 whereas my '10 Prius has a cd of .25 (lowest cd of any production car in the US). With all other things being equal is there any significant difference in a radar or laser shot at say 1500' on a stock car? How about one with some countermeasures attached to the front end?
