My gut feeling was that the actuation was hydraulic due to how fast the movement of the actuator is. It does not look electric to me.

 

They are hydraulic per Porsche's press release on the car. They said electric actuators that fit the packaging requirements cant withstand the forces involved, nor do they operate fast enough.

I looked into active rear wing stuff a while ago and nothing electric fit the bill back then and now seeing that Porsche couldn't make it work with electric actuators, I'm glad I gave up on that path. The actuators I played around with were either too big, too slow, or too little force.

 

Confirms my hunch on that earlier... Thx Chris!

 

weird, Patrick Long says in the video they're electric.

 

Front flaps in the splitter tunnels are electric, maybe he is referring to that?

 

From Porsche it does say hydraulic.

No, the new video with him and Jay Leno they specifically talk about the wing and the forces on the motors to move the flap up/down with the downforce involved and how fast it must react.

 

After reading/watching about the new 3rs, it's really pretty wild for a street car that most will prob not get the use their built for. If I could get an allocation at a reasonable ask, I'd trade all my cars and just drive that everywhere. It's awesome.

 

Correct, I thought it was funny, and immediately made me think back to 996 wing hydraulics... I hope these have a better longevity. But, I'm sure as an RS car it has a maintenance interval set pretty lenient

Ironically, the hydraulics are located within the decklid!

 

All, or at least almost all, of the modern active aero cars still use hydraulic actuators, or in some cases pneumatic. Hopefully the technology has improved a bit since ours was developed...

And fortunately for John, his car makes enough power to not have to worry about dumping the downforce/drag on the straight... he can just turn up the boost..

 

Yep. With a running weight of just over 2800lbs and 900whp, We are not really concerned with the tradeoff of slightly more drag for lieu of less complexity / less weight. Honestly, I doubt there is going to be all that much drag anyway. The Zebulon wing uses the latest generation CAD optimized airfoil and the Zebulon guys told me to set at an almost flat angle of attack when used with the trailing edge flap. For what it's worth, I was told that the 996/997Cup wing profiles were horrible from an efficiency standpoint.

 

Three pounds to a horsepower is a lovely power to weight ratio.

 

Adequate...

 

Makes one wonder how high you're going to turn it up...

 

900whp! Car must fly in the straights. Can’t even imagine how much fun that would be!

edit: would love to see the wing and how you like the stability with wing on the chassis.
