Active Steering on the track

Can anyone comment on how AS acts on the track? I love the idea behind it and fact that during slow tight corners, less steering input is needed. This is definitely an option i would consider getting if it works well on the track. Thanks

I don't know...I would not want active steering on the track...on second thought those pesky hairpin turns...

From what I recall, the feel/tension of Active Steering correlates to the vehicle's speed. Since a track offers a variety of turns at different speed, I wonder if the driver will feel deceived/tricked or will grow accustomed to the system.

even in hairpin at sears point i did not have to do anything ridic with the (non active steering) wheel. I had to shuffle maybe once? its totally not a big deal and i don't think it is worth it to have the computer second guessing you just so you don't have to shuffle your hands in the parking lot

Active steering seems to be transparent for me at least but I don’t run any traction control at the track or autocrosses. One thing you do notice is that you have to be smoother with your wheel input as you can tend to turn in/turn out to fast but you adapt fairly quickly. At a tight autocross active steering is certainly an advantage.

After trying AS at the track, I wouldn't want anything else.

The system makes for a faster, better, and more accurate reaction from the driver and the car. Go try it.

I agree AS is awesome on the track. I've also been suprised that none of my instructors that have driven my car have ever noticed or asked if my car was equipped with AS.

I have active steering and an LSD, the first few times that I tracked were a bit scary because I was still getting use to the way the car behaved with the LSD. I actually lost the car a few times and spun out. (Not having the traction control on didn’t help either. However, I am now use to using both systems and I feel a real connection to the car at all times. You kind of get use to driving with the AS, however, its a bit nerving when I jump back into a car that doesn’t have an LSD or AS because the handling nature of the car is completely different. On long sweepers the car is very easy to control, I noticed that the car loves to go sideways on double turns and tight corners. Defiantly gets your heart racing. Overall, once you get use the AS system it does inspire more confidence on certain parts of the track.

I have active steering and I find that you do not need to adjust input depending on speed. Once you are used to it, it's all natural. A 90 degree turn requires that you turn the wheel a quarter turn. A tight 180 hairpin would require that you turn your wheel half a turn (crossing your arm - 9-3 to 3-9).

So turn in can be done much faster, and the added benefit is that you get to be very very smooth in your inputs! On the flip side, if you are jerky it could be interesting.

makes sense, you turn your steering as needed when you see the car turning, you turn more when you need to and stop if you dont need to anymore. No one really notices and remembers how much they turn the steering wheel when they did a U turn or a 90 degree turn.

Um, I think it was designed for parking lots, not hairpins. :p

Active steering feels awesome on the track. Actually, once you've got used to it, you don't even notice it anymore until you drive a car which doesn't have it. That's where you'll miss it

I wouldn't buy an E9x without that option. The standard power steering feels alot "rawer" and less refined, as it requires quite alot of force on the steering wheel.

Exactly.

One of the best improvements over my previous E46 Alpina B3. I've done around 80 laps so far with active steering on the Nürburgring and have no problem with it.
