nothing new here ... we are going to have to wait until the new year for one of the top tier magazines to publish a proper review based upon a multi-day test drive.
My bet is Evo GTPurelyPorsche or Total 911 will come up with the goods, if not "monkey" harris himself.

but this particular review is simply an enumeration of the press release information...

True.... seems the MT is really really good.
From my side (how much I like MT) a live around Brussels area with A LOT of traffic jams, so nearly obliged to take PDK as the car will be on a daily use.
But I meaned it don't expect a review which gives a big difference with the other Carrera S models.
I did not wait for a review to order it.

As others have pointed out, this is merely another standard 991 trim (it is not a GT3 or Turbo). That means it isn't worthy of a full review from an outlet that has already covered the current-gen 911 in detail (most other sites will be in agreement).
What do want to know that isn't covered in the story? Ask away, as I spent eight hours behind the wheel.

Also, the previous 997 GTS had its suspension 'tuned' vs its counterparts (I believe stiffer sway/anti-roll bars and perhaps spring rates), how do any changes relate to SPASM, any details?
Comparing the 2 Coupe GTS to an S, does the wider track of the GTS make a noticeable impact on the handling on-track?
Not specific to the GTS, but how is the character of the X51 vs the std 3.8L
enquiring minds

sorry ... but that's how it read to me.
Well, lets see, other reviewer's mentioned that the 7MT box on the GTS has apparently been revised in some manner improving the shifting over the other models previously equipped... any insights?

That is right from the press release (as are all italics from this point on).
The big news is the shift lock (I never used 7th, for the record). I couldn't tell a bit of difference with regards to reduced shifting forces or improved precision.
With regards to the suspension:
"As sporty top models of the 911 Carrera model series, positioned beneath the 911 Turbo and the 911 GT3, the new GTS sports cars have an exceptionally dynamic chassis. This is based on the wide track of the all-wheel drive 911; the rear track was increased to 1,560 mm on the rear-wheel drive models as well. The benefits: an even lower tendency to roll and even better stability in bends. Porsche Active Suspension Management (PASM) is standard equipment. It delivers an optimally tuned characteristic in each individual active damper under all dynamic driving conditions. Compared to 911 models with a conventional passive chassis, the ride height of the GTS is ten millimetres lower. This lowers the centre of gravity, which is another plus in dynamic driving through bends. Thanks to PASM, the driver can choose a much broader spread between greater agility when driving quickly through bends and relaxed comfort on long trips.
In vehicles with a manual seven-speed transmission, Porsche Torque Vectoring (PTV) improves traction and tracking stability and reduces load alteration reactions in conjunction with the mechanical rear differential lock. The even higher-performance PTV Plus is used in vehicles with a dual clutch transmission. It offers an electronically-controlled, fully-variable rear diffe- rential lock. In addition, PTV or PTV Plus improves agility and steering precision by brake interventions at the rear wheel at the inside of the bend."
The wider track likely won't be noticed on public roads, but it does improve stability at the limit (of course, a skilled driver in a standard Carrera will still run circles around a newbie in a GTS). That said, the GT3 (991, 997 and 996) are still much more effective enthusiast track tools than today's GTS, which tends to use a smorgasbord of electronics to keep it on the pavement (the GT3 is twice as engaging, if you want my opinion).
"The engine of the 911 Carrera GTS models is an advanced development of the liter 3.8 liter six-cylinder from the 911 Carrera S. An additional 30 hp was gained by completely reworking the intake manifold. The variable resonance induction system that was specially developed was essential to boosting the engine's power and torque. In this system, the central intake manifold flap is supplemented by six additional resonance flaps, one in each individual cy linder runner. They are simultaneously opened or closed based on engine speed and acce lerator pedal position. The result: oscillating tube charging provides for better fillingof the combustion chambers. This ensures that an optimal amount of fresh air reaches the com bustion chambers in all driving situations, generating high torque at low revs and more power at high revs.
In parallel, airflow within the engine was optimized. The goal: more charging at high revs for more power. To achieve this, the intake ports of the cylinder heads were geometrically optimized, and they were machine-lapped, i.e. smoothed, by a new process, which reduces their resistance to air flow. New intake camshafts with a larger valve stroke and a modified valve-spring kit enable induction of more fresh air into the combustion chambers over a longer period. The results: improved resonance charging which, in conjunction with the re worked engine control system, leads to optimal charging of the combustion chamber. The driver can access the full torque of the 911 Carrera S engine, and thereby its elasticity, as well as more power from the GTS engine at full throttle. This leads to very impressive dri ving characteristics in the 911 Carrera GTS."
Porsche engineers are first to admit that the engine tweaks are most noticed at the higher end of the tachometer. It breathes easier.

I've got a 24-page PDF press release from Porsche that I believe I can post here, assuming you really want the technical details. Let me know.
