Quicky ABS question

Yes but one of the nicest things one could do with cheap sensors and processing technology is build an active suspension system* (ala banned in F1 fully active suspension) for reasonable money. I expect that within the next 5 years we will see fully active suspension on road cars. This will mean amazing handling probably better then KW v3 but with mega smooth ride quality on straight roads. One could argue that active roll bars as in the BMW system and active dampers as the ones Audi and Ford are now using used together is very close to fully active suspension.


* Active as in both springs and shocks are to some degree replaced with electronically controlled hydraulics, this was developed years ago by ISTR Lotus or Williams F1 and then quickly baned by the rule makers.

 
Yup. This gent speaks sense. I completely agree with Scott, but would also add that the two cars with serious stability programmes (as opposed to ABS/Traction Control) that I have driven annoyed the hell out of me with their nanny-ing. Particularly the Boxster. You could throw that HARD into a greasy corner, apply the throttle, wait for the back to start to push out and .... it didn't. It cut the power and (metaphorically) said "Naughty boy, I'm going to take away all that fun torque because you are misbehaving and handle like a ford fiesta until you behave yourself". NOT something I want a car to do (the regular passenger-seat speed limiting device is normally more than sufficient.)


Oli.
 
Active suspension is a driver aid in my view. It is not interfereing with driver input like traction and stability control systems do. I'm not so sure how quickly systems will move on from the current conventional spring/active damper arrangement. The complexity and added weight of having hydraulic systems on a car might kill that concept. It's also strange how that technology hasn't been implemented in other race car series since being banned in F1 including German DTM where it seems anything goes as far as technological driver aids go.

This last point is an interesting one. May be that the rules stop this technology since in the past it was very very expensive, the weight is not bad since of course it had to be light to be used in F1. AFAIK other F1 technology such as pneumatic valves are not used elsewhere. I can see Active Suspension gradually creeping in, probably with Active ARB's and Active dampers as a first step.
 
The new Cayenne has adjustable ARB's so I think we are already at that first step. I guess Pneumatic valves are only really of benefit at really high RPM so have not been justified in any other arm of motorsport due to the extra complexity and cost. Also with F1 cars they are generally alot lighter than the regulation minimum weight limit therefore carry ballast. I can only guess the extra weight of the active suspension hydraulics just ate into the ballast.
