The 328i was better balanced and more neutral.

Mid-engine placement in the BMW? I assume you just mean it is placed slightly more behind the front axle than with the Audi.

Btwy, while journalists like to talk about the perfect weight distribution, it is worth noting that doesn't translate in ideal polar moment of inertia. One involves integrating lengths while the other requires integrating squares of lengths. All these cars are still inherently more prone to understeer, although obviously some more than others.

What you are referring to is indeed rather subjective and a strong function of what one is used to. Most traditional racers always prefer RWD over AWD, because that is what they are used to and because it is easier to loosen and control the rear end. There was a video on this forum a long time ago about a pro racer driving an AWD 911 and the 2WD counterpart on a tight indoor course. The AWD went faster, but he preferred the feel of the RWD. My guess is that it had a lot to do with what he was used to. It is a very subjective thing. But I do know what you are talking about.

Btwy, I don't see in the C&D review the paraphrase you are referring to. And it is worth noting that although Audi suck some summer tires on that car, it is not a sport pack A4 (steering has four spokes).
