lol, i get your point about snow/ice i must have expressed my point wrong,

APR have also tested their 600bhp/600lb.ft 2.5 cars in sweden but im sure it wasnt all about drifting etc, oh and i belive that was on 93ron fuel too!

i had no idea you were on about super efficiency, but at those figures from a breif look, i would say it is possible,

modern diesels during re-gen process are developing the same power so drivers do not notice power loss, and temps are going from 300ish deg C to 800+!!

slightly off topic, but technology available today, may not be too far away for companys like that to produce super efficiency, agreed?
but if this were the case, i would have hoped to see over 1000bhp from that particular engine, fuel dependant 103RON/E85 etc may have a less agressive map on super boost, at -20deg the air density would be a massive help IMO

thaughts on that maby?
