Per wikipedia, the E46 M3 skid-pad is 0.89g.
Per Road and Track, the B8 S4 skid-pad is 0.96g.
As has been covered ad nauseum on the forums - you cannot place empirical numbers on the "butt dyno."

Default Yup, we got the sport differential

(Just saying, AWD vs RWD is different... trust the AWD a bit more)

Oh.. and assuming you got the sport diff... you got the sport diff, right? I mean, prior M3 owners and all..
We specified that sport diff because of the M3 experience she had.

Probably has to do with the roll rate of the car. The M3's tighter damping on a lighter car is going to give you a lower roll rate than the heavier S4 with the more compliant damping. That can tend to make a car feel less in control even if there is more grip

I think she may be talking about the steering feel. The M3 does feel more connected to the road, however it doesn't means it handles better. The only thing that I would criticize on the s4 is the steering feel at higher speeds (120km+). in all other areas it kicks the e46 m3's butt sooo bad.

probably just not used to the feel of an AWD car vs. RWD...then add that an M3 is well...an M3 and there you have it...the S4 is a 335i killer not an M3 killer.

That's true as well... the S4 tends to roll/lean a bit at least with my stock suspension. (I have the sport diff, but not the full ADS). Slap a set of sways on the car, and that would tighten things up.

Considering how much you don't care you sure seem to enjoy calling people out with your opinion.

OP I agree with a number of comments here, driving style is very different. The S4 with the sport diff seemed to respond very well to lavish helpings of throttle through a corner. I only test drove the B8 S4 though, the owners here will have more tips from longer term use.

I think that your wife, and presumably you drove her E46 M3 also, are probably in a better position to evaluate the situation than the rest of us once you get a similar level of comfort on how each car behaves.

Cheers

You wouldn't even necessarily need sways, as that would have the side effect of possibly reducing overall grip or inducing more oversteer or understeer. A set of adjustable dampers with better valving would probably work wonders, especially in the rear.

Default Thanks!

Thank you all for the helpful comments. They are doing a lot to open her mind to the idea that her sensations in the S4 are just different, not indicative of inferior handling in comparison to her M3.
I can't really judge myself because my Avant was my all time favorite car, and I drove her M3 only rarely. She was very possessive about it, I have to say. I was surprised she was willing to give it up when we sold my Avant and her M3 to buy the S4.
