I believe he was being facetious and the Houston line was just a stabbing. No guns, no little girls being lured into prostitution, etc. I thought his comment was funny.

Pretty cool video. I think the 4 wheel steering stuff is pretty nuts, be interested to see the longterm approval of it and durability. But how it turns the rear wheels with the car at high speeds and in the opposite direction at low speeds is very smart. Is the 4-wheel drive system in any smaller sportier cars yet? Or just the big ones? Just curious if anyone has spent much time with one and pushed it to see how it’s different.
Jimmy, how much extra hardware does that add back there for the rear steering. Is just a hydraulic box at the rear that controls the in/out push or is it a lot more stuff.

In that video it looks like they are showing the torque vectoring of the sports diff, not four wheel steering. I don’t speak or read German but that looks like a recap of other videos from the percentages that they show.
Four wheel steering is very cool though. I think it first came out on little Mazdas and then it has basically become exclusive to the bigger vehicles like semi trailers by now. There were some Yukon Denalis with four wheel steering for a while but I am not sure if they still have it. Also there was an option AHK for the European BMW 850 CSIs that was rear wheel steering. But it only worked at higher speeds (like above 40 mph) and it would turn the rear wheels in the same direction as the front wheels. That is why a big heavy boat GT car could out handle the Porsches of the mid 1990s.
Each OEM that has tried rear wheel steering has done it their own way. I remember that the BMW system was hydraulic and ran off the power steering. Which was like asking for trouble since those cars had so many power steering issues and they ran a hydro-boost power braking assist too. Sadly my 850 has not moved since April because of no power steering or power brakes. Other OEMs have tried electric rear power steering, which is how I would do it if I were in that field. The semi trailers probably run the rear steering off hydraulics. They need rear wheel steering more than the little passenger cars to get those long trailers around highway on/off ramps.
^Cool info. Yea the german threw me off and I was just thinking it was 4-wheel steering. Didn’t think about it just being the torque vectoring. I know BMW introduced it in the 7-series a couple years ago, so I figured this was Audi playing catchup on the new premier line, not them showing off the new diffs . . even though saki’s intro said Diffs.
I didn’t realize multiple manufactures had tried it back in the 80’s though. Pretty cool. It’s certainly another component to give ya headaches and break, but it is one that is pretty interesting. I’ve just wondered what it could do on a sports car. I think the new 991 GT3 is going to have it, so it’ll be interesting to see the reviews and if it makes a difference in cornering G’s and lap times.

Maddog, I looked at a few related videos and it looks like the new four door 6 series have a similar system as the old 850 CSIs. But the M cars don’t appear to have it. Instead they have an active M differential so BMW is probably using something similar to Audi’s torque vectoring system.
Axel, Never liked Hondas so I didn’t even know that. Also their engine spin backwards, which is weird.
Don’t forget Nissan had hicas 4 wheel steering. One of my adolescent dream cars was a 300zxtt with super hicas. Early models were hydraulic actuated later were electronic.
