I wonder how that feels to drive?

I had an 88 Honda Prelude with AWS and it was a trip to drive.

Incredible U Turning Radius. And at speed on the highways all four wheels would turn in the same direction so it felt like you were "FLOATING" into the lane.

And everyone who drove, ya know friends 'n ****, especially the dudes would Trip out when the felt it too for the first time.

Wonder if it is more subdued.

Chevy did it too with some of their trucks a few years back. But I'm almost certain they have abandoned it too.

Have you not watched any of the video reviews so far?!
It's nothing like the Honda set up!
You don't feel it's there in the GT3. Not to mention the technological advancement that we're seeing these days compared to the 80s. In those terms I fully trust Porsche and their engineering team. The reliability of the whole RWS system remains to be seen...

Max turning angle is 1.5 degrees in the Porsche. 5.9 in the Honda.

I sure hope the car doesn't feel floaty on the road. No journalist has commented as such.

I continue to think it's best to view it as a variable wheelbase rather than true RWS, since the max rear angle is so small. As noted, reliability remains to be seen, but otherwise I like the idea, and Porsche seems to have implemented it very well.

Yup, big difference from the prelude. You could actually SEE those wheels turning. I think in the gt3 the aim is just to reduce scrub from rear wheels.

More like elliminating the pendulum effect of the rear engined car at high speed while also neutralizing understeer at low speed. I tried to explain how I think it works in some older posts in this thread:

Yes, yours is a more accurate explanation. Thanks
