Have 42000 on a 2010 with 3.2. Highway averages about 7.0-7.3 L/100 k driving Calgary to Vancouver two passengers and fully loaded with holiday cargo going about 110-120 kms/hr. Coming back due to it being almost uphill about 7.5 L/100k average. This was actual fuel purchased and Km's travelled.

Yeah, that's seriously awesome. Here are my stats so far:


Granted it's more city driving than highway. Hmm... maybe I should ease on my lead foot.

I wonder how you can get that. Driving in Saskatchewan on a highway that is pretty much flat I average about 9.5-9.8/100km. Driving at 120km.

Cruise control and some places slowed traffic for construction but it's the best i've seen so far from this engine.

I do not want to offend you but your car is the world record for low fuel consumption (for Q5 3.2)
Audi has written that the engine 3.2 consumes outdoors 7.6L per 100km which refers to ideal conditions (constant speed of 90km / h, air temperature, straight road with no climbs, one person in the car, etc. ..) As is known factory car ever Provide information on fuel consumption, which are always smaller than is realistic. In your case it's different you car uses less fuel than the official data it sounds unbelievable + two passengers and fully loaded with holiday cargo going about 110-120 kms / hr
My friend has a Q5 3.0TDI and the spending on the open road the 8.1-8.4l per 100km and you 3.2FSI petrol engine consumes 7.0-7.3 truly amazing

No offence taken. It hasn't always been that way. Got to remember that each day we were driving the outdoor temps were at least +20C. Few months back I drove to Sask for my father's funeral and barely got 10.0 L/100kms going there and back. Since then I had all the injectors replaced due to what Audi said was "poor fuel" which doesn't make any sense as I run Shell 91 exclusively. Maybe the new injectors have something to do with it? I'm meticulous when it comes to tire pressures and not driving with any windows or sunroof open etc. Not complaining as cold weather is coming and the efficiency will go down.

Thanks.
Recently got back from a road trip. Of the gas receipts I remembered to document, total km= 1320, total L = 133.16 for a grand total of 10.08L/100 km. Mostly highway driving. (my previous reading of 15 was from daily city driving)

It's normal consumption.
Do not you confuse my Q5 2.0TFSI sometimes in town when the crowd at traffic lights know to show consumption of 14-16 liters, but only in the city.

Was the air conditioning on? That adds an instant 0.5 L/100km, regardless of how efficiently you are driving.
