My 2001 Outback with 95,000 miles averaged 25 mpg, althought the Passat does not have all wheel drive both vehicles are esencially the same size. The Passat averages 36-37 mpg overall. The Passat just hums along, yet has plenty of accerlation with the turbo. Much better ventilation than the Outback. Seats and adjustments are way out from the Outback, especially legroom and right seat comfort. Currently at 6500 miles, will see what the next 100,000 or so tell us.
