It means average and the 1 means for that trip. Mines gone down with less traffic... maybe I'm driving faster! 218 miles to my previous tank of fuel. That's from full to the top of the red.
I have also noticed on another screen it says '2'? what does that mean?
Tbh my mpg seems worse since the weather has been warm!
It's summer. The weathers warmer so it takes less time to warm up, which during warm up the car runs rich to help warm up quicker. Also people tend to drive a bit easier during the warm weather.
I normally averaged 31 on my route, turning Econ on I'm not getting upto 39 on my way to work in my S3
Jeez I'm on 26.9 av at the moment on my commute. As said above I do use the air con a lot, I hate being too hot
