Thats not that bad really mate. Is that driving like a granny on the long run then or do you think you could get a bit more if you tried?
C4llyT, i was actually thinking of the LPG on an M5 or M3 earlier. Im not sure how well it would work on performance cars like these, or even if its possible, but it would certsinly be good to have decent performance AND economy!
