Anyone else getting spectacular fuel economy with their A5 Sportback?

The NRCan rating is 10.0 L/100km city and 7.0 L/100 km highway. I am achieving consumption levels considerably better than the ratings over the first 2500 km with the car. I recently took a summer trip of ~1500 km and averaged 6.3 L/100k, which is almost 45 mpg (Imperial) - phenomenal! In city driving I am averaging 9.0 L/100km, which is 31 mpg (Imp.).

This is in the summer, with the A/C on, and much of the driving was during the initial 1500 km break-in period.

I believe that the NRCan ratings were revised to more accurately reflect real-world conditions, but I never expected to achieve results better than the rating.
