So I drove to Vegas this past weekend and just wanted to share my MPG's. I have an F30 335i with the auto. Drove from San Diego and averaged 77 mph, trip took 4 hours and 40 mins, and averaged 33.7 MPG this was on comfort mode with one passenger and two small suitcases. I guess what I wanted to see is if anyone else has looked at what the most efficient speed would be for gas economy. On the way back I wanted see what the eco-mode would do, but it seemed to not make a difference. Best speed to MPG i found was 80 MPH =34MPG. going 75 MPH averaged about 32mpg. I made sure that it was flat and not going up or down any inclines. I guess i got a little board. GF doesn't like going over 80's but if anyone has any input at higher speeds I would like to hear.
