FWD is meant for a few things :
- to let inexperienced drivers keep the control. No matter how fast you enter the turn : the car will gently understeer...
- to reduce steering angle (because of the transmission) so as your wife will spend hours in manoeuvring the car and you'll still be the boss (well, it's a French point of view : don't take it too seriously).
- to make room for the luggage at the rear of the van : there's no doubt the boss is never the one you'd expected when it's time to travel (this is a general fact, this time).
RWD is made to :
- put weight to the drive train when needed (during acceleration, at the same time FWD losses drive...). This also helps when braking (if you remind to be progessive).
- separate the steering from the driving (better for feeling, performance and tyre wearing too).
On top of that, the RWD architecture helps the balance, by moving the weight on the rear side of the car. We all know the best sportscars (meant for racing or not) have mid rear engine : that's the reason why. And, strangely, I don't remind of a car who would have mid rear engine and front wheels drive. Yet, the opposite is true with the Panoz for exemple (mid FRONT engine, but rear wheels drive : it's all about weight distribution).
By the way : has anybody ever seen a decent FWD supercar ? Last, think about the bicycle evolution...
Yet, it's a matter of a fact that common FWD are excellent cars... My Citroën C4 is almost perfect on twisty French roads, has smoked a lot of powerful beamers in the Alps, and is very forgiving for drunk driving ( I'm kidding, DON'T DO THAT). It's a shame that there are no Citroëns in Forza (look at WRC championship...).
P.-S. : Sorry for my poor English level. I hope you'll have understood the main part of my (attempts of) explanations.
