according to the new issue of evo. they had a special about steering systems and they quoted franz enderle, porsche head of 911 suspension and chassis ...

I'm just curious. What is the advantage of electric steering in a performance car?

AYHSMB

Less parasitic drag on the engine (due to the power steering hydraulics pump). Gives you around 5 hp for free, or better mpg.

IMO not worth it !

KINGSRULE

Definitely worth it

Less hanging off the engine is more to the wheels

DrJay

It seems to work ok on the GT3 RSR...

i think its great idea, pump always runs and always pulls off engine and rarely is used... new system only works when it's needed.

Here's a question, if PDCC equipped and hydraulic pump for that is installed anyway, could that in theory have powered the steering, too? Or would the pump have had to be bigger, or two separate pumps?

Also allows for profitable options like lane-departure and self-parking, not to mention economies of scale with lesser Porsche models.

If Porsche ever actually offers self parking on a 911, we'll know that the end of the world is near......

You kidding? It would be a huge hit in South Beach...

An electric pump = excellent idea

Weight moved forward, minimize parasitic losses etc
(and they can still save the planet with the "up to 0,1l /100klm" lowered consumption. )

The safety-oriented-self-correcting-speed-sensitive-torque sensitive-pulse-emitting-electromechanical-steering -driver-assistance nanny = epic fail


BTW if you order the 991 with PDCC , the hydraulic pump for this system is fitted in the old steering pump's position..

Mike in CA

Maybe, but it would still be a signal that all hope is lost....

For the reasons most people buy a car like this - none. Porsche is up against some serious EPA CAFE problems if the next wave of regulations go into effect, and they are not allowed to average in with the VAG fleet.

So game over, as there is no more steering feel on the 991. My RS is a keeper than. Probably use the 991 to tow the RS to the track.

When the 991 GT3s come along and you have to wave by a train of them on the track at least you can take comfort in your steering feel.
