Dropped off my old e91 320d MSport Tourer and picked up my new e91 320d MSport Tourer Edition yesterday.
On my old e91 I left the computer to run right the way through to 90,000 miles without any resets and on my 163 e91 and got 40.9mpg over that whole 34 months. Mixture of motorway and fast A road driving.
400 miles in less than 24 hours (I had to route from Essex > Norwich > Cheltenham > Coventry > Cheltenham) with normal type of routes I did the 90,000 miles on and am getting 45.3mpg on my new 177bhp ED model.
So far stacking up with Gizze's comments.
