328i or 328xdrive?

Can anyone honestly tell if there is any difference in driving feel between 328i or 328xi? I feel like the 328i would drive better. At what speed do you notice the biggest difference of how they drive?

Anything less than 90% on public roads it's unlikely you will notice anything. Racetrack: yes you will notice. Bad weather (snow especially): you will notice a difference, especially if you have snow tires on.

Not always. An absolute statement like that is never correct.

I don't have a 3 series but in my '13 535 xDrive, under normal driving it's virtually impossible for me to distinguish "x" from RWD F10s I've driven. Please note, for me "normal" is not a triple digit drive on a Formula 1 Road course!!

Actually, the suspension is tuned towards more understeer compared to a regular 328i

Struts are the most obvious difference, but front control arms are different, and a few other various suspension bits are different.

It's an absolute statement simply because the xi suspension setup is different.

You won't notice much difference between the two. xDrive models, as stated, are more prone to understeer. You may feel torque steer but on 328, I doubt it. 335 probably more so.

The only reason to get xDrive is for the added height clearance for snow. If you live in an area that has deep snow, xDrive can help because of the higher ride height. But if you live in an area like that, you should bed driving an SUV.

Otherwise, a set of good snow tires (not all seasons) will get you by.

I'm referring to the properties of understeer (and oversteer) being a transient condition, due to the instantaneous conditions of the road, braking, accelerating and such changing the weight distribution contributing to those transients.

For instance, one is taught to brake to recover grip at the front, eliminating the transient understeer and inducing oversteer. In SOME conditions, the additional 140 pounds or so decreases understeer.

Yeah, yeah, too pedantic for you'al.

+1

OP, keep in mind that 99% of BMWs sold in this country will never be driven past 50% of their capabilities.

If you ask "at what speed can you notice ..." chances are you will never drive the car past above mentioned 5/10ths. No offense meant. Seriously.

You can notice awd or rwd at speeds as low as 40 mph if conditions are right. You might not be able to tell the difference at 150 mph if conditions are different.
