I can get as much as 29 mpg on a steady 65 mph flat highway cruise. I can also get 6 mpg at a full aggression track work.

I get city ~17, and I don't drive like a maniac all the time, and 26 highway. I average about 21-22mpg. On a recent 1500 mi trip I averaged 75mph, and 26.5mpg. This is a 2002 M3 with 12K mi., and my mileage is still slightly improving as the car gets older...

This is up from 20.5 since adding the Borla exhaust to the Shark (synergy). Average was 23.5 until I drove 2 straight days city only. Shift at 4k through 8k, 75 MPH on the highway (some bursts higher - only in the pack).

This is from an old post of mine a couple of months back right after the firts year of ownership:

************************************************** **********

This is a graph of the Miles per galon for my '02 E46 M3 since I got it (picked up the car on June 2002, so it has been almost one full year of use). Every single gas fill is in here. Hard to see, but the blue line represents the car's built-in MPG calculation. The red line represents the actual MPG (derived from a full tank based on gallons and mileage). On average, the car's computer was 5.21% higher than the actual MPG figures. As you can see, most the of the time the car's computer is optimistic!. Some of the spikes and lows are due to highway trips (higher) or bumper to bumper traffic (lower), but you can see that I am averaging close to 20MPG since I got the car:

Now, for the actual averages:
(computer's values reset at every fill-up)
- actual MPG: 19.69
- car's MPG : 20.62
- car's MPH : 37.92 (daily drive within the city, as you can tell!)
- miles between fill-ups: 267.33
- $ per fill-up: $21.62
- price per gallon (premium gas): $1.60
- gallons per fill-up: 13.60

Not bad, considering this is my daily driver and it comes with a 333HP engine !!!
