As above, I was hoping for some improvement over the V8, but the 3L seems worse....... average is 16MPG However, I do most of the time drive drive in the manual mode (because it's more fun), so I tried the fully automatic and got 22MPG over the same route......... I guess that's the answer,,, if you're bothered about fuel consumption! Also, on possibly the same subject, is it me or does the first quarter of the fuel gauge drop like I stone.......?? I swear you can visibly watch it go down....!!!
