240 loses about 17% through driveline.

Can somebody give me a wet site,  or tell me about the advantage or disadvantage of AWD cars, and how they compare to FWD and RWD.
Thanks.

well obviously the advantage of an AWD car is all 4 wheels are pushing/pulling the car, the disadvantage is because it has a larger drivetrain you loose more horsepower in it, and you will find an awd drivetrain will take less horse power before major modifications need to be done to it due to the extra load on the transmission and of course the transfer case.  And a awd car is awesome in the winter.

i dont know what advantage a fwd car has over other cars for racing, prolly none, better in snow though....

the advantage of a rwd car is that when you lay into and the car is pulling forward the weight "transfers" to the back of the vehicle giving you more power to the ground being that the "extra gravity" is pushing the wheels down harder. Unfortunatly the rwd's are obvoiusly the worst in wlippery conditions.

This question is too vague to give a proper response to, but I'll try anyway.

Despite popular opinion, without active diffs or a heavy rear torque split, AWD sucks on dry pavement.  If you don't believe me, watch a WRX at an autocross, either stock or modified.  They basically drive like a overweight FWD car except they understeer a bit less on the exit.  It takes some real manhandling or a huge rear sway bar to break the end loose.  I regularly outrun them in my s13 despite being down around 75 hp simply because I can stay on the throttle longer.  Great for dirt/wet asphalt/drag racing though.

Here it is:

FWD - Loss of power through driveline is minimal.  Steering and power is put through one area.  Heavy understeer in corners.  Weight distribution is usually heavy in the front.

AWD - Greatest loss of power in driveline.  More stable under uneven road conditions.  Mild understeer.  Weight distribution is medium-heavy front.

RWD - Moderate loss of power in driveline (10% stock 240).  Steering and power are put down separately (better turning radius, higher sensitivity to movement).  Low understeer to moderate oversteer (depending on car).  Weight distribution is almost as close to 50/50 as possible.  

Midengine - Loss of power similar to fwd.  Steering and power are separate.  Neutral to heavy oversteer (best agility of all).  Weight distribution is even or rear heavy.

Back in September of 2000,

Sport Compact Car did an Article about this.

Some good reading, enjoy.

I think this should be archived. Correct me if I'm wrong please.

And 240s lose between 10-15%, depending on vehicle conditions.
