GT 2016 Technik Service Information Book
# PA CNN GT4 16
117 pages of technical information, systems function, more. These books are great for those who want to know more beyond the owner's manual, press articles, etc. Ask your dealer to get for you.

Sounds cool. I have one for my Cayenne. It is what they use to teach the service techs. At my dealer the tech showed me one for the GT3. Had a document for each model. I've asked Sun Coast about it but they said it is not released yet........

It's available for download on P9. I'm going through it now and it contains a wealth of information. For instance, before now I've never been able to confirm whether the crank in the 9A1 is forged or not. It is, as are the rods. Pistons are cast, however (which is not a bad thing in a normally-aspirated motor).

"Map-controlled thermostat
The thermostat is an insertion map-controlled thermostat with a heating element.
The electric heating element of the map-controlled thermostat is energized via the
DME control unit. The flow of current through the heating element (electric resistor)
causes it to heat up, which in turn influences the expansion element in the thermostat
and enables it to be opened. Actuation by the DME control unit is performed by means
of pulse width modulation (between 2.5 and 97.5%), which means that the coolant
temperature level can be continuously controlled.
The usual coolant temperature is 221° F (105° C) when the engine of the Cayman GT4
is at operating temperature; it is reduced to 185° F (85° C) during sporty driving and in
Sport/Sport Plus mode by opening (energizing) the thermostat. This supports a
performance-oriented driving style.
The DME control unit can also have the thermostat closed by switching off the
heating current. A precondition for this is a coolant temperature of less than 216° F
(102° C). The map-controlled thermostat starts to open at 216° F (102° C)
+/- 4° F (2° C) when de-energized and is fully open at 239° F (115° C).
The coolant temperature is measured by the engine coolant temperature sensor and
the radiator outlet coolant temperature sensor and transmitted to the DME control unit."

Well here's an unequivocal statement from this document that you won't find in equivalent Corvette literature:
2.8 Thermal management
The Cayman GT4 meets the high requirements for vehicle operation under all conditions, including in hot countries, without restriction. The cooling performance is specifically designed for this purpose. The cooling system ensures that the engines run in the appropriate temperature ranges for optimum and permanent high performance.

Interesting, the "peak torque limiter" that AP referred to in the Evo interview and that nobody seemed to understand what it was turns out to be a clutch delay valve, though apparently it only introduces a 20ms delay.
And the gearbox oil is 75W-90 with a claimed service interval of 112K miles!! I've seen RL members recommend 10-15K changes for cars that see any track time (not 10-15K track miles, mind you), so I find this surprising. I know that cars that see track time should adopt more shorter maintenance interfaces, but ~10x shorter?? What gives here?
And somebody already posted it in another thread, but this doc says that Dynamic Trans Mounts are part of Sport Chrono, even though the configurator info about that option doesn't mention mounts (it does on other models) and the Standard Features list includes dynamic mounts -- but Page 49 claims "standard assignment of the active transmission mounts" and includes them in a list of GT4 features that are known to be standard and that also includes PCCB, but PCCB is called out as optional whereas the dynamic mounts are not. Ugh, I really hope we don't end up with another GT3 memory seat situation on our hands....
