Re: Why the bias against front wheel drive cars?
I got this from http://www.epinions.com/content_4158759044
Why doesn't FWD work? Now the problem doing this in FWD is the fact that the front tires do the job of both turning AND driving. So you really can't afford to lose traction at the front. The other thing is that FWD cars do not naturally oversteer. They understeer at high speeds. Again, try the shopping cart. Instead of pushing from behind, try pulling the cart from the front. Pay attention to the direction the front wheels are facing in a curve and then try to pull harder in that direction. The cart will probably start skidding outwards and lose ability to hold on to a tight curve. Typically, to get the the oversteer you want with FWD, that requires hard, short, quick braking. Some drivers and cars can do this with the brake pedal, but usually, this requires the e-brake. And of course, because you can't afford to completely lose traction because this will just send you out in a straight line to the outside of the curve, you need to make sure your entry angle is a little more shallow. It's very hard to chain drifts in FWD, because the rear axle is just giving you passive sliding friction, which slows you down (hence the name "a**-dragging"). Often, it also requires extra suspension tuning so that the rear suspension is harder than the front, and also some lower-traction tires in the rear. So FWD is always at a disadvantage to RWD in a race should you choose to drift because it has such a slow entry speed. Of course, as a general racing rule, what really matters is the line, and if you take the ideal line, you've got the fastest outcome whether you're drifting or gripping.

The ideal setup is a car that has just enough weight on the front wheels to control the car, In other words almost all the weight transfered to the rear.
Good examples are the Funnies and AA/F dragsters. |

Re: Why the bias against front wheel drive cars?
FWD cars are much better than RWD cars in winter though!

the source of my disdain for FWD is when i hear all these kids talking about taking their FWD cars out to go drifting. And first of all that is not drifting it is sliding out of control whereas drifting is a controlled loss of control with a set angle to be reached. not speeding up to 45mph and pulling the E-brake. if that was all it were than anyone could do it

Re: Why the bias against front wheel drive cars?
The real reason you cant chain drifts in a FWD is because its to hard to control onces the car's weight is moving around in the back, Unlike RWD there is not throttle to modulate....and you cant just wait for the wheels to even out on there own, its just like the oversteer snapback you see on games like GT4, its a pendulum and its hard to stop/straighten out.
like the dreaded flatspin of top gun, although yes, sometimes you can prevent it from getting to the point of no return.

The big problem with FWD from a track performance standpoint isnt how it handles (All cars follow the same laws of physics), but rather what happens when you start to apply throttle coming out of a corner..... But any way, to quote my self from another thread on this Quote:

The only way your going to conclusivly show the differences between FWD RWD and AWD is if you make a test where all the cars have the same weight, wheel base, and Tire size/compound. other wise you are as much fighting the individual car MFG's design flaws as you are the cars drive train layout. |

Re: Why the bias against front wheel drive cars?
Understeer is a very very very frustrating feature of FWD cars. My grand prix loves to do it every time I take turn a bit faster than usual. In the rain if I turn under moderate acceleration car stops turning and goes ... well across the lane I wanted to turn in forcing me to get off the gas. But the positive about it is that understeer is much more easier to manage than oversteer.

Re: Why the bias against front wheel drive cars?
and no one told honda either. integras beat 325s all the time in SCCA. also there are a couple crx's that destroy everything in time attacks in japan. the fastest time attack car for a while in all of japan was a crx. but in order to make a truly fast FWD track car, it needs to be set up with a super stiff ass end so the rear tires slip at the same time as the front. and a wider track helps too. although these examples exist, its far easier and cheaper to make a RWD car handle, accelerate, brake, and do everything else well than any other setup.
btw, for all of you who think you need a FWD car in the winter and snow, you just need to learn how to drive. i drove my lowered 240sx around all last winter and never crashed, spun, got stuck, or anything. no abs, no traction control, RWD, lowered, some basic M+S tires, and thats it. in minnesota.
