Wouldn't seem so hard to use this hydraulic steering (pump driven by electric motor like in 997 race cars) in the GT3/RS for better feel and good fuel economy...

If someone does this I would be interested in the results and if they a good following suit. A

I was actually hoping that Porsche might use this equipment in the road cars, but your idea of retrofitment is interesting too. I imagine the greatest challenge would be integrating the hydraulic steering into all the electronic nanny systems (PSM, 4-wheel steering if they use that, the inevitable "Sport" button for electronic steering, etc.).

It works wonders in the little air-cooled car...just to the right of the 986 cool box.

Just hearing the spin-up and -down is worth the price of entry.

That transaxle seems promising... a VERY MUCH SHORTENED design that does away with the old helical R&P and associated LSD, in favor of a compact straight gear (don't know how it's done yet) and likely new diff design.

This is shaping up to be what the marketing claims--a totally new car. Shows good promise!!

p.s. Notice how the output shaft in gearbox is in a position that can be extended for 4WD applications. There's a LOT of forward thinking in this (pun intended)...

The electric pump driven hydraulic steering system would be very cool for the street GT3/RS, but it might not be practical. I was reading an article yesterday in the Feb/Mar R&T on the new Corvette. The head of the development team was talking about the decision to use electro-mechanical steering in the new Stingray and mentioning that Chevy really had no choice but to switch. No suppliers were willing to submit bids for a hydraulic system since almost everyone in the industry is moving to the electro-mechanical systems.

Baawahhhh. As busy as you're going to be in that new ride, please insure that you have Advil in your overnight kit.

Once again, you may thank me later.

The Maclaren MP4-12C uses electro-hydraulic. And Porsche obviously is already a customer for this hardware too, since it's used in all their 991 race cars...

High cost is also a likely consideration for low volume parts; not so much an issue for quarter million dollar supercars and race cars. I don't disagree that electro-hydraulic steering would be optimal for the GT3, just passing along what I read regarding steering in the new Corvette and thought it might be relevant to the discussion......
