I saw that post as well - his specific comment was that he could feel the road better. In back to back drives of two cars with the same CIP, I did not notice this. Rumor has it that AS has been tweaked in some of the upgrades (yet I've never seen any mention of it in the BMW release notes). Yet he also mentioned that he had CIP 20 in his old car and even mentioned that he had the same tires. Very strange. It could easily be a personal choice.

Again with the bad AS comparisons... active steering is -NOT- the only thing that contributes to the reduction in required steering angle. ARS (dynamic drive) also greatly reduces the amount of steering angle required to execute a turn. This is due to the "self-steering" characteristics that ARS imparts to the chassis. These non-sport cars you both are comparing to your usual rides are missing ARS -and- AS. It's going to be hard to tell which is more to blame for your displeasure.
We recently had another report from a multi-E60-owner who got a new car without AS reporting how much better his Sport, non-AS 07 is compared to the AS cars he had before.

On the active steering topic, the relative ease of turning at lows speeds is hardly another bad comparison. :thumbsdown:
AS hits the mark here bigtime. Who needs road feel going slow? Its an option thats valuable everyday.
Good point on ARS and its interplay with AS.
I'm curious as to how early and often ARS works, as I've assumed its for more aggressive situations? The reason I ask is a 20 mph turn in my AS E60 feels so much better (far easier) than the non-AS non-sport. AS was advertised to cover this? Aye? How much ARS impacts this situation would be interesting to hear about??CVT Benhogan
PS My compliments to 525 owners. The loaner is not a 530, but in fact a 525. Nice and quick. Of course I'll rough it up when its returned to dealer tomorrow and the 550 will get its turn on the way back.

Could also be the previous person that drove the car. Why do we assume that the dealer set it? My loaner had a limit set to 125mph. Haven't had a need to change it.

As you can see from the chart, not only body lean, but required steering angle is reduced significantly at all speeds with dynamic drive. Hence my continual ire with regard to posts that credit AS with all the reduction in steering angle. Regarding whether or not the original post(s) were bad comparisons - I never stated that I had an issue with the slow speed steering ease comparison. That's a well-accepted benefit. My issue is with comparisons made at speed, which a good portion of the subjective analysis in this thread pertains to. I would say that my preference would be to hear about people who have driven Sport AS (any code rev you want) and Sport non-AS, but that's just the scientist in me yearning for valid relevant testing...

ARS works at all amounts of lateral acceleration - it's more concerned with "g force" (lateral acceleration) than the vehicle's speed. This chart is lifted from an article that shows a BMW internal document comparing a 7 series with and without ARS. It stands to reason that the implementation may be even more aggressive on the 5 series due to the more sporting focus of the car.

UUronL,
Great chart.
Two quick thoughts. ARS works fairly early and dramatically. Wow. Second, it seems the steering angle is dampened by lateral Gs and speed. It also appears to be below non-ARS by a fairly consistent margin, which only slightly widens as lateral Gs increase. If this is true, one could conclude that AS is primarily responsible for the greater ease in turning at lower speeds. With ARS actually dampening this function with greater speed.
What I can't say is the feel at high speed. Your right, only a comparison of non-AS sport versus an AS sport could begin to answer this. That said, AS would induce less turning angle for any given speed. I'm sure this has been debated already. So subjectively, one could conclude that AS feels either more increasingly stable or more numb relative to a non-AS sport as speed and Gs increase?
Thanks,
CVT Benhogan

All good questions, but I'm not sure I have any more answers than you do. I'm not sure I completely understand all of your statements above, and I don't quite understand how you're using "dampening" so I won't address these comments directly. ARS as you know is a hydraulically actuated active roll system. My understanding is that adjustments made to the rigidity of the roll bar mechanism imparts self-steering characteristics to the chassis in addition to controlling body roll. My understanding of "self-steering" is that the chassis actually steers on its own without input which is why it requires less user input in terms of the angle that the steering wheel is turned. Either that or the tweaked chassis is somehow more sensitive to steering input making any steering wheel angle affect more turning than it would for an untweaked chassis. I'm not sure that the difference in explanations would be anything more than semantic, but these are some of the different ways of expressing it that have come to mind.
Regarding AS, my understanding is that its primary function is to adjust the steering rack's ratio so that it is also variable - the idea being that it can be optimized for different speeds. The most obvious benefit is that it makes less input at the steering wheel do more turning work at the front wheels. I suppose in certain situations it does the opposite too. In terms of safety, I think AS is integrated into DSC, permitting the computer to instruct AS to make certain adjustments to facilitate recovery. I think the computer can also instruct AS to make adjustments if the car moves in response to crosswinds.
Some have opined that AS ads a layer of disconnectedness, but I really can't speak to this with any authority. I simply wanted to illustrate that AS -and- ARS directly contribute to reduction in the required steering wheel input angles. Also, that it may be hard to attribute that "special feel" to AS solely - that is unless the people making the claims have made the comparison I suggested.

Very informative. My post could have been clearer but I was drinking in the airport bar on a delayed flight. 
For dampening, I meant less steering angle for ARS versus non-ARS. (in reference to your second graph)
I now get the point that less roll requires less steering angle, as the attitude of the chasis is flatter thru the turn. Do you have a angle/speed graph for AS?

A limit light and chime popped on over 85 and the revs seemed to drop off. Would be a nice feature to engage should your friend speed racer ask to borrow your car. 
Yeah, glad to have a loaner but deserved one too. Happy it was bimmer and, its very probable, it won't be last time. I'd like to try a 330 next time, of course with a sports package.

actually i want this feature, probably in the ecu
put it to shift at 1800rpms and limit the mph atlike 15 for those valet parkers........
seriously this would be a good idea, no?
