HELP! Published speed info needed

I need some published info about any Mazda 6 (6i would be best) on the distance (feet, yards, inches) it takes to go from 0-40. I got a ticket for going 39 in a 25 with my 6i but there was no way I was going that fast based on 1. The distance from the light to where the cop said he clocked me 2. the fact that I was just slowly cruising through town on my way home. 3. didn't show me the radar
I'm coming to you guys to help bust this dirty cop and need the published info as proof that he was totally full of b.s.
 
 
Thanks a ton!!!
