Re: Ladies and gentlemen, the new 991...
RC:
I have to laugh about the fuel consumption claim: My Carrera GTS Cabriolet eats up to 21 l / 100 km. My average fuel consumption (mostly city but some Autobahn too) is 19.6 l / 100 km right now (Sport Plus active all the time, PDK in manual mode) and even with Sport Plus turned off and PDK in auto mode, I never got below 15 l / 100 km. While I don't really care about fuel consumption on my cars, these (low) claims can be very misleading.
The only car(s) impressing me regarding fuel consumption were the Q5 TDi (the 170 hp version) and a BMW 3 series Diesel Coupe (not sure what engine but I think it was the 330d with 245 hp). The Q5 Diesel consumption was 9 l / 100 km, despite the fully loaded car (luggage, four persons) and the BMW 3 series Diesel Couple had 8 l / 100 km. I wasn't really trying to save fuel on both, impressive. I also once drove a X6 35d to Austria and back and the average Diesel consumption was 10 l / 100 km, fully loaded car and Autobahn speeds included.
So while Porsche's claims sound amazing, they aren't really practicable on a sports car.
On a very policed highway journey of around 250km mine does 9l/100km. The Q5 does 7l/100km.
But if I do a detour of 20km to the same destination through a nice stretch of B road (bends, short straights of 200km/h, but no elevation) the 911 drops to 11.5-12l/100km.
The economy claims refers to steady speeds with high gears (6-7 frequently) and not violent acceleration. They are only useful for comparison.

Re: Ladies and gentlemen, the new 991...
I tried hard but never managed to get my Carrera GTS Cab below 12 l / 100 km, unless I was driving 120 kph at max and using only 1/3 throttle, keeping the engine in a higher gear all the time.
I also owned a 355 hp Carrera S back in the days and the average fuel consumption was always around 15-16 l as far as I remember.
How do you guys manage ?

Haha we don't all have autobahn to play with. Over here, even the 125kmh Regino mentioned would land me in hot water with the authorities. So it is easy to achieve 10l/100km on mainly freeway driving. I think I can even do that on the GT3.

997 Carrera (first generation): according to BC I am on average between 12 and 13 liters. Drives on the motorway at around legal speeds (120 - 140 km/h) gets me around 11 liters. I once drove 150 km at cruise control 120 km/h and I ended up with 9.9 or something like that , a personal record 
(most likely I had a hint of tailwind)
On the how I manage, I "blame" my father, who taught me to drive (with a diesel); my father always told me it was bad for the engine to keep it on high revs when the power is not used, and therefore I drive my manual like the tiptronics seem to do: shifting up when I am not accelerating, so the rpm are often between 2,500 and 3,000.
Some say this is not the best thing for the engine 
, although I do not feel like I am lugging it.... Tiptronic software seems to agree with me...

Anyway back onto the car itself. I wonder why they have developed PDCC for the Carrera S? I mean, PDCC is fantastic on SUVs (like on our X5M) and big heavy sedans where roll is part of the game, but on a relatively light weight sports car? Is it necessary? I don't ever recall any of my past and current Porsches suffering from massive roll issue! I guess it is ok if it doens't add weight to the car, but I am guessing it would add quite a bit?
PDCC is not only about reducing roll angles during cornering. Depending on bandwidth and tuning, it could be used to do a couple of additional (more important) things:
- Reduce single wheel bump stiffness for added comfort (it's effectively like "turning off" the roll bar when a single wheel hits a bump
- Dynamically adjusting roll stiffness during cornering (this is like playing with roll bar stiffness in the middle of a turn!)

I see, makes sense.

From the official release information, PDCC on the Carrera S is the new thing as regards dynamics.
Lots of consumption&emission measures.
--"Form follows function"
.... and why no 0 to 100km/h ( 62 mp/h ) time with the manual gearbox 
Would it be that these times are worst then the 997.2 PDK Carrera S ?

Re: Ladies and gentlemen, the new 991...
Yeah, AFAIK in Oz it's 100km/h max ... it's doubly painful because the distances are so great that sometimes it can feel like the journey is never-ending ... plus the cops have a zero tolerance policy ...

...this thought isn't that far away. The last days when stocks again crashed and we all heard a lot about imminent recession and the small economic growth in germany (0,1% in the last quarter) I thought by myself: "well, recession isn't desirable for nobody but on the backsite the Porsche prices may drop and the delivery times get shortened...
Ok, just a dream but of course I prefer a intact economy.

PDCC is probably the option that gives the car such unbelievable N'Ring time . If the option maximizes the contact of each wheel on the road in every corner, then you definitely gain seconds !

I used to do that with my Audi S4 until I had an epiphany: The idea is not to try to get it to the lowest number, the idea is to try to get it to the highest number..!
If you want fuel consumption, buy a Pruis!
It's like when I started getting the shakes from drinking too much coffee. I figured I could either cut back to 3 cups - or add a 5th cup at 3pm. The shakes stopped.

Re: Ladies and gentlemen, the new 991...
On my way from St. Moritz to Munich the fuel consumption of my Boxster S was 8.2l/100km. How did I manage? a) wife in the car (not fit and getting see sick driving the mountain roads) and b) Swiss police and their speeding tickets c) heavy rain.
My personal record for the Boxster is 7,2 l. Fun fuctor: very small. Don't know if the Boxster is build for this kind of use. I don't want to retry this kind of record attempt.

My fuel consumption is 11.8 l/100 . This includes some track days, but otherwise mainly city + speed limited highway driving.
The consumption is lower then when I had a manual, as win in auto mode with PDK, the car drives ...not like I would ... but more like my grand father would
Anyway, this ' forces' me to consume less, as there is no point putting in sport plus and manual when in heavy traffic.

Re: Ladies and gentlemen, the new 991...
BlackOctober:
To compare....
This comparison emphasizes that one of the ways the 991 looks cleaner is by eliminating at least one (or two?) of the engine vent flaps/vanes - new look is just less "busy".
But for those looking for more rear room, it does look like the rear seat backs now line up with the front edge of the rear glass, rather than coming up almost mid-way into the glass as the 997 shows - should result in at least more head room even if impossible to judge foot-room in these views. This assumes the rear glass is roughly the same size. Also shows the longer roof.

But this could also show how actually the engine has been pushed fwd.

And look at that! IT IS actually wider at front!!
That picture is a bit misleading, as it is not wider at the front. It is also pictured in a wider angle than the targa picture further below therefore comparing rear passenger room is rather difficult:

My ex-997.1 Carrera S had average fuel consumption of 12-13 L/ 100km on my daily drive which was 80% highway- 20% city driving with an average speed of around 90 km/h (I did around 180-200 km/ on the highway)

I am sure the glass panel roof will be an option as it has been for the 997 and 997.2. Regardless of the look of the roofline when its open, its always nice to have an option when u wanted a bit more air comming in.... I personally don't mind the side profile of open roofline, its not perfect, but it does not bother me that much....
By the way, totally agree. I do not find the rearspoiler to be beautiul either when extracted, nobody cares to mention that. In my opinion, the sunroof on the 911 always had a ridiculous size and therefore made it obsolete. I am a huge fan of those bigger sunroofs as they are suitable for most of the time without the drawbacks of a convertible.
