It's definitely nearing the end of nearing the end. But I don't believe there has been any scoop on a successor just yet. Anyone know more?

It helps a lot when you have to drive in and out of the garage, that is for sure. In very slow corners it won't be there, in faster corners you will see a more stable car, basically as if it were a little bit longer. On the Nordschleife it definitely works.

PS: Weight of the little actuators is probably neglectable.

I had a car with, locked it out and removed the actuators. Much improvement.

RWS is a huge improvement. Probably one of the most significant performance improvements since the DCT.

Don't think the right engineering went into that car.

It was regarded as one of the best engineered cars during its time - 1989-1994 - and one of the fastest on the Nordschleife. It operated exactly like people are saying in terms of the RWS but nobody really saw the benefits, so it often got removed as junk. The model was updated twice between 1994 and 2001 but retained the same basic drivetrain. However, when a modernised version of the basic layout was launched in 2008, the RWS was gone but the car once again produced some astonishing times. I remain sceptical about RWS.

RWS isn't a purely mechanical development. What it does is based on all sorts of sensor data and interactions with TC, ESP, etc. I have no doubt in my mind that RWS from the early 90s is crap compared to today.

You would think that F1 would have it first if it was truly helping high speed cornering,...unless it's a weight, or a regulation thing....then again, they could reduce the weight if it was worth it & legal.

Benetton trialled it years ago in the driver aid era but Schumacher and Patrese (i think, unsure) didn't find any real benefit. I think by the end of the test they had intentionally switched it off. That was years ago though, with modern sensors, computers and electronic development it's hard to say if that would be the case now.

I think it's banned nowadays anyway in most if not all forms of motorsport.

I believe it was ahead of its time, thinking about it now, the reaction and tuning capabilities on today's RWS systems make those of old rather dated. Lockout bar or bust from 89-94...I have not heard much negative talk in the post '94 systems, nothing used in anything serious with these cars (GrpA etc)

Was back then too, with inputs measured at either 100Hz or 1000Hz depending on the version.

It was essentially the same system on Skyline GTRs R32 through to R34, in conjunction with a computer controlled centre-diff, which had previously only been done on the Porsche 959. The R35 GTR was launched in 2008 with no RWS. You would have thought by 2008 that computing would be more than up to scratch and the microcontrollers they tend to use in these apps are nowhere near top end computing technology anyway.

I think in LMP it might be worth it, because there's a regulated minimum weight anyway, and it could help save tyres over a long endurance race. But if it means adding an unnecessary 50kg or so to a road car, which is never lapped for near as long, then IMO the cons outweigh the pros. The only beneficial use I can think of, is helping a 675LT do a 3 point turn.
