There have been previous threads on TFSI economy... but,
I now have 5000 miles on the clock and I get between 20-22 mpg average (giving me about 240 miles from a tank). Best I've had is when I went to Bluewater (from Portsmouth) xmas shopping and got 28mpg.
Doing deliberate economy driving (light throttle, change up at around 3k, lift off approaching traffic to avoid stopping etc.), I've had 24mpg out of a tank, so for the sake of 2mpg I now thrash it and upshift at 6k
.
I tried setting cruise control on an empty motorway at 70mph in 6th with the aircon off and over about 5 miles after resetting the average, it read 25mpg.
SO, THE PUBLISHED FIGURES ARE B.S., but then that's the way they're forced to calculate them (i.e. theoretical values, not taking into account drag, rolling resistance, gradients etc. etc.)
