850/s70 Awd In A Turbo?

Ya you are probably right...but the security of AWD while driving around the Sierras during the winter would be nice too.

I like those drag radials though...I might need something more driveable on a daily basis...or else another set of Volans...those for dry days and others for wet days.

I really like the AWD - the lack of excessive torque steer & wheel spin on shifts is much nicer. I feel that I have to see how close to 300bhp I can get - just because everyone seems so dead against it. The M66 AWD Trans is from the 300bhp S60R - so that's no problem, it's just the bevel gear & viscous coupling; but since the R AWD put out 260, I don't see how 300 will break the bank.

BTW - I'm using 235/40x18's - and it does break loose easily with the rear driveshaft disconnected.

I drove FWD in Alaska for years you will be fine. As for FWD/AWD you are looking at 13% drive train loss vs 25%

Both may make the same 300hp but the FWD puts down over 250 of it where as the AWD puts down over 40 less. Add that to the extra 400 pounds and you are not gaining anything.

Interesting aboutteh drive train loss.

on your comment about driving in Alaska...that is actually a very good point and exactly why I would prefer AWD...I am a life-long California non-snow driver. Even with racing school and 20+ years of driving so little of it had to do with snow/ice that I am much more likely to make that split second mistake and be done for than someone who has driven in snow with any amount of regularity. ...but, for the small amount of time I end up having to drive through it while on business trips I doubt I would want to lose that much HP. I guess it is all about practicality again and I prefer power to safety when the safety I am talking about only applies to a very small amount of my yearly driving.

Thanks for the input.

Just do no drive stupid. A ten year old can drive a track if the speeds are kept low enough. Do not drive beyond you ability, AND common sense, and you will be fine in anything.

ya, sensible driving has gotten me through 20 years of driving with no accidents but that doesn't mean a stupid mistake can't still be made while driving in snow/ice conditions...but, like I said, it sure seems like your point about drive-train loss is a much bigger loss than the gain I would get from the safety of AWD for those rare times I would prefer it.

I am off to do some tire shopping.
