Info from press release:
---------------------------------
Audi drive select - up to four different cars in one
Those who drive the A4 hard and enthusiastically can choose between two sports suspension settings, or alternatively rely on an innovative technology - the innovative system known as Audi drive select. This is available in various stages, which influence an increasing number of technical components and functions on the car: accelerator pedal response, tiptronic shift points, power steering assistance, the steering ratio and the action of the electronically adjustable shock absorbers - another new feature.
The driver can select the comfort, auto or dynamic modes at switches on the centre console. If the A4 is equipped with the MMI control system, a fourth mode, "Individual", is available; this enables an individual profile of 24 settings to be configured. Audi drive select transforms a single A4 into up to four different cars - a range of driving pleasure, dynamism and ride comfort that is unmatched in the midsize car category.
As fast as a professional rally driver - Audi dynamic steering
The new A4 features yet another pioneering technological development: Audi dynamic steering. Its key element is a superimposed gear system that alters the overall ratio according to road speed and the chosen Audi drive select setting. This concentric-shaft steering gear is extremely compact and light in weight; it has a precise action free from any slack. It was first developed for use in robots and for space travel applications; the expedition vehicles on which it was installed have already traversed the surface of the moon and Mars.
Audi dynamic steering makes the steering ratio more direct at low speeds, with a higher level of power assistance. This renders the steering extremely light when manoeuvring, and only two turns of the wheel are needed from lock to lock. As the car's speed increases, however, the steering ratio becomes gradually less direct and in parallel with this the amount of power assistance is reduced. At high motorway speeds the A4 can therefore be driven smoothly and has excellent straight-line stability.
Audi's high-tech steering can do even more. It is closely networked with the ESP and therefore receives precise information about the car's attitude as the handling limit is approached. If the A4 threatens to oversteer, for instance after an abrupt avoidance manoeuvre, the steering performs slight corrective impulses in the direction needed to reduce this tendency. Such corrective action takes place faster than even an experienced rally driver could react. This rapid response means that brake applications are often not needed, so that the car continues its journey more smoothly and dynamically.
The system also takes action if the car understeers: it selects a more indirect steering ratio for a short time, the aim being to prevent the driver from turning the steering beyond the point at which the tyres still have plenty of road grip. With these capabilities, Audi dynamic steering represents leading-edge technology in this car market segment.
The optional-extra damping control permits individual suspension settings to be chosen. These are based on the lowered sports suspension. Continuously adjustable hydraulic shock absorbers permit the damping characteristic to be varied individually at each wheel. This means optimal contact between the tyre and the road in almost every situation, for greater safety and more dynamic road behaviour.

that sounds like the planetery gear system that BMW uses on the 5 series
from what i hear, a lot of people don't like it. i just hope this stuff isn't too intrusive, but i guess that's why they let the driver choose his/her own settings.

everything about this car is starting to remind me of a bmw....the radio and climate control is look
ing like the new 3 series....if i wanted bmw looking interior i would just get a bmw and benefit from the untouchable resale value.

Perhaps but...
... the climate control has been around since the latest D3 A8. Controls for the CD changer, well, yeah, might not be the nicest vs it being all together like the Symphony, but everything's gone MMI now. And the shape of the various components of the interior takes on some of that trapezoid shape like the front grill.
It's one of those things, BMW comes out with the iDrive and everybody else follows or comes out with something similar.
