I recently averaged 83 mph over a stretch of 300+ interstate miles coming back from the Sebring races. My S430 averaged 25.2 mph during that run. I routinely average 22+ mpg in mixed driving. At 75-80 steady mph I usually get 27+. All this is with the AC on, cruise set when possible, and not paying particular attention to slow acceleration and other mileage-adding efforts.
