So all of us have heard of the new "clutch kick" feature on the new GT3. I was curious as to if this could be used in order to heel and toe downshift. I have always been a manual guy because I enjoy heel and toe. Can the new car change gear while both clutches are disenganged? For example, when approaching a corner, could you brake, pull both paddles, rev match, then downshift? or will the car just go back to the gear it was in?

 

I'm trying to understand why you would even do this?

The PDK will do all of this for you.

 

One gets a PDK so that one does not have to do what has been said in the post :-)

I am guessing hitting the gas pedal to rev match will be unnecessary as the PDK software will autmatically rev match. The neutral feature was developed by Porsche as a direct result of me sending them a letter saying hey guys, with a PDK I can't rev my engine at a red light to show off, can you help? and they did............. LOL

 

I understand that the PDK can rev match and basically read your mind when you just pull a paddle or leave it in auto. What I am wanting to know is, could you use this new feature to treat the transmission as a manual box? Do you get the best of both worlds? As I said earlier, I like to heel and toe, but if I could do this with the clutch kick feature, i could finally start to take paddle shifters seriously. (I know they are fast, but i like manual)

 

I'm just taking a guess here because I haven't driven the 991 GT3, but when you pull both paddles, doesn't that just drop it into neutral while maintaining the gear that it was in? How would you downshift while pulling both paddles?

 

With hands on both paddles and your right foot doing the heal & toe, your left foot would be available to hit the stick forward for the downshift. This could be the ultimate in driver involvement and a move that drivers around the world will strive to master.

.

 

What about right-hand drive cars? Might be a little awkward for the left leg.

 

I drove a manual 991 which comes with the rev match. When shifting it would rev match on the up-shift and the down-sift. I could still do the heal-and-toe, but it would still rev match before going into gear. That made for some awkward times.

So my guess is that on the PDK, regardless of what you do with your right foot and whether the gear is in neutral or not it will still rev match.

Also, given the dual clutch set-up, I am not sure if there is a true neutral as the car is always in gear, it just seems like neutral because the clutch is disengaged. This last point is another guess on my part.

 

On the new GT3 there is no way to "manually" do a heel toe downshift. The transmission automatically does the rev matching throttle blip on the downshifts.

The clutch kick feature as I understand it is no different than pushing in the clutch on a manual transmission while the car is in gear; it just disengages the gear. Releasing the peddles just re-engages the gear you were in. You cannot change gear while pulling both peddles in, it just disengages the clutch.
Possible uses for this feature would be if tracking and you spin, pulling both paddles in and hitting the brakes would be equivalent to going "both feet in" on a manual The other use would be on launch if you don't want to use launch control. Select 1st gear, pull both paddles back, rev car to whatever revs you want, release paddles equivalent to dumping the clutch.

Cheers

 

Kingezo, go test drive a 991 Carrera S with PDK...you will then understand PDK. What you are asking to do can't be done and is totally not needed to be done.

 

I also think these are the main reasons why the feature is offered.

And perhaps if the driver wanted to freely rev the engine without putting the PDK selector into nuetral first (for example, at a stop or while coasting).

It could also be useful when coming to a stop from say 3rd gear and you don't want the car to shift from 3-2-1. You could just pull the paddles for neutral and coast to a stop.

I don't believe that you'll be able to heel-toe with this system. You can try it, but it may automatically rev-match when you release the paddles.

We'll just have to wait to find out.

 

I don't see how you would be able to downshift in that sequence. Maybe in auto mode? Quite literally you have no extra body parts in manual mode to exercise a downshift. Maybe with your elbow? Or have a passenger at all times to lend a helping hand...
