OK, so if I put my 2000 Passat 4Motion Wagon in there, it says
17(city), 24 (highway), and 20 combined. That's a joke. I rarely get below 18, and I would say 20-22 is typical city mileage. Highway at 55-65 mph is about 26-30 mpg. I have had as little as 28-32mpg at constant 65. This is in line with what other people I know get.So, please take these ratings with a big, big grain of salt. Moreover, with some knowledge about how, when, and why your car consumes less gas (hard acceleration at low rpm without lugging), you should do much better than what is suggested here.
