 My new 2014 Audi Q5 TDI has a little over 1700 miles. I've been very careful during the break-in period, which happened during extreme cold temperatures and much snow and ice on the roads for a few weeks in February. The car would start flawlessly every time even at temperatures of -20 F in the mountains of Colorado. I've averaged 25.5 mpg in the city during cold weather and snowy roads. On a 180 mile round trip from Winter Park to Steamboat Springs, where you start at 8800 ft, go down to 7000, then up to almost 11,000 ft and then down to 6,800 ft I averaged 35 mpg with 5 people in the car, skis on the roof and a fully loaded trunk. From Boulder to Colorado Springs and back I averaged 41.5 MPG.Update: After owning this vehicle for two years I'm just hoping it is not too good to be true with the diesel scandal. I bought it because it had power and speed to spare while using very little fuel and polluting less than a gasoline car. That may still be true for CO2 emissions, but it is not true for NOx emissions, and that is very disappointing. I'm hoping the fix will not reduce my power or fuel economy. I've averaged almost 31 mpg over 25,000 miles, with no mechanical or electrical problems. My biggest complain is the Google Earth based GPS. The time to arrival algorithm is not very accurate, especially when driving in the mountains. It can be 30 minutes off on a two hour drive. In the city though, it is accurate enough.I bought snow tires to get one more season out of the all seasons it came with, but I still think the original tires will not last as long as expected. The Audi Q5 is excellent in the snow with these new snow tires. I did notice an appreciable difference in traction, but it does not corner as well as with the all seasons, as expected.Last year we drove the car from Colorado to California and from Colorado to the East Coast. It was such a pleasure we may do it again this year. The seats get a bit hard after 6 hours drive, so we bought a seat cushion for long trips after the first one and our bottoms thanked us.Update: The major change I've seen is my mileage has increased to an average of 31.6 of combined driving in the third year, from 30.8 the first year. I don't know if that's due to the engine loosening up and becoming fully burned in, or because the original tires are getting worn out. I have 34,000 miles and I have measured up to 40.5 MPG on one trip. Usually the computer is off by up to 1 mpg, so figure at least 38-39 mpg on the highway through 3 Colorado mountain passes.I hope Audi can fix the diesel cheating problem without affecting performance. I don't know of any other car that can perform similarly or better (range, MPG, AWD, ground clearance, acceleration, comfort, luxury, quality). Maybe next year the plug-in hybrid can come close or surpass it.Update (Mar 26, 2017): Audi may offer to buy back my 3.0 TDI Audi Q5 if they cannot solve the diesel problems by December 2017. I would take them up on the offer if I could find another vehicle that performed equally or better than what I have for a similar price. I don't think there is one, if I want similar range (600+ miles), acceleration (6.2 sec 0-60 mph), fuel efficiency (30.8 MPG combined, down a bit because of the use of snow tires), road clearance (7.9 in) , turning diameter (38.1 ft), and combination of length and cargo space on an AWD car. I am very happy with this vehicle after 38,500 miles but I don't want the pollution stigma.
