OK, So picked up my first Audi in December. Now 4.5K miles in and 4 months of ownership later I have only good things to say about this car; my best to date. I note that many people on this forum drop off once they have collected, so I am taking the time to post for those who stay around and help those visiting while awaiting delivery, they have been very useful for me while in the same position and since.
Previously owned a 2.2 Civic and no matter how I drove it I never managed to achieve more than about 52Mpg, typically 42mpg (around 2 mpg lower than my COD). I recently had a situation where I had to drive from Dundee to Glasgow between 60 - 65mph, not my normal speed range. I held mostly around 60mph on cruise and economy (not convinced that any drive setting would have given the same result) , which on this trip resulted in 75 to 80% 2 cylinder mode. My DIS reads around 2mpg high typically when doing actual calculations and I normally, now run in get 44-46mpg on my daily commute, this has been steadily improving from my 38mpg start in December. So 56mpg on an 80mile motorway run is awesome for a petrol engine, but critical it stays in 2 cylinder mode to achieve, the continuous readout was hovering between 60 - 63mpg so I reckon I could have crossed 60 had I not reached destination. I finally hit 58.9 (sorry for the blurry picture - taken by passenger and took ages even to lock onto gauges. (see attached)
Also I cant believe that when driving a petrol I can move up the gears quicker than my Civic - 16mph 3d gear, 24mph 4th gear so in crawling traffic with 2 cylinder mode engaged you still get mid 40's return, which is pretty amazing too, however it is very very easy to "break" the mpg on my 10 mile trip compared to a diesel, brief periods of fun can drop you below 40 mpg easily.
Anyway thought this worth a post for those considering the diesel vs COD option, if your careful it can reap rewards. In gear motorway performance too is mighty impressive with effortless silent speed build from 60 - 80mph very close to my wife's 2.0l mini SD, which on paper just should not be the case with the torque difference's. I also find that it's much easier to drive slower, I typically drove my civic around 75mph on the gauge vs 65mph now - not for fuel efficiency but the car is so quite its difficult to discern the speed from 60 - 80mph - they feel the same. The speed alert set to 80mph is a must for me as it drifts easily way beyond if your not careful.
I don't typically drive for mpg, but traffic flow typically eliminates the ability to have fun, but when the opportunity presents itself I get no where near this level of return
