The advantage of AWD is that your ability to accelerate fast is independant of the weather. When done properly, "launching" an AWD vehicle for a bit of fun at a stop light can be done without damaging anything.
I had an 09 WRX a few years back and had ample oppurtunity to drive my dad's 135i. My dad's car weighed a bit more than mine but the extra weight didn't help much. Unless it was warm and dry, full gas = spinning rear wheels.
True, most cars, even AWD ones, come with tires that aren't really the best for performance, and AWD helps a lot in lower traction conditions. The truth is that it's best not to drive like a hoon in any car in low traction conditions, unless you really know your car perfectly and there aren't any other cars or obstacles in immediate risk of contact should something go squirrely.
And getting great performance tires for a FR setup like a 135i, Vette, Stang, etc, usually mean that you get fantastic grip on good surfaces, but even worse grip should it be raining (or early morning damp).
