why is rear wheel drive better? RWD?

im assuming it is because every car brand either makes all wheel or rear wheel. porsches, ferraris, benz, lambos, BMW.

i have a 325ci and one random guy said nice car and its good because its rear wheel.

so how does rear wheel differ from front. i know in snow rear is shit but on track and stuff. i dont understand it when people say it turns better?

The physics of it - a rear wheel drive car gives much better control in performance driving. In truth, a good driver will love rear wheel in snow (until they got stuck) because rwd gives better overall car control. It turns better because the back wheels are doing one chore (driving) and the front wheels do the turning and the better part of the braking. In front wheel the front tires are forced to do everything and the rears are just going for a ride. Having to do more means it tends to do everything a little worse.

Those cars don't make rwd a good thing, it's (partially) rwd that makes those cars good things.

awd = the best
