I thought it might be fun to see who can get the highest MPG on the 25 Mile loop. I didn't do anything crazy - I was on the PA turnpike. Never dropped below 58 MPH. Drafted a van driving 62 for a few miles and coasted whenever possible. I could not believe I was able to hit 77.5 MPG! I have verified the car's computer via manual calculation numerous times and find it to actually be pessimistic. So, let's see your best numbers!
