True, a mate of mine has a '91 325i M-spec Alpina Edition. He had it tuned properly, at around 220 kw (300hp odd) at the fly, and it does like 8-9 litres per 100k's. It's more economical than the 4-cylinder hatch my folks run! And he drives like a lunatic. Still i reckon the v10 would still drink quite a bit. Too much of a temptation to redline it in every gear to hear that sweet engine, and feel da powa!
