Cayman GT4: Where are we up to now?

[Motorhead]

Agreed D. I also think that it's more important to compare actual manufacturer times at the 'Ring rather than magazine "hot shoe" driver times, and a pre-production GT4 posted a time of 7'40". I seem to recall that Preuninger mentioned in one of the February interviews that they [the GT dept.] were waiting for the weather to improve before taking a production car on the circuit to confirm, or possibly improve, the time set. Maybe Walter will have a go..! Jeff

 

[MrDemon]

the car has -1.5 neg camber at standard, so you could now adjust that to a more track wanting -2.5 and go and set a time. that's has to be worth a quit a few seconds.

 

[Motorhead]

Yes. I'm sure the Sport Auto mag time used the standard set-up. I can't see them having time to faff around with the geometry, whereas Porsche can run an optimum set-up for the circuit and conditions on the day. Jeff

Here's another impressive time for the GT4 at the 2.6km Hockenheim Short circuit: http://fastestlaps.com/tracks/hockenheim_short.html 41st place in 1:10.1 isn't too shabby. Jeff

 

[MrDemon]

the factory have accepted the full order now, just waiting on a build date , this is for a Sept build but with 918 style seats. the guy before me August build has decided to go normal seats to get the car early. hoping for a PEC date much sooner though to drive them.

Do the 918 chairs have height adjustment like the standard buckets[&o] Can you order the 918 chairs in full leather

 

[MrDemon]

it's electric height, but not heated, no full leather, but then if NOT heated you want alcantara to sit on. Am I right is saying no 918 seats for 981 SPyder now ! on the plus point normal buckets are great and can be heated now, but no height adjust.

 

[Motorhead]

So, electric height adjustment but the seat back rake isn't adjustable. Is that correct D? I presume that you've gone yellow with yellow bits, as discussed previously. Good to hear that you've pushed the button on it. When I spoke to the PEC manager last month, he said that he didn't expect to get a GT4 until July at the earliest, so you could have a fair wait to get a drive. Jeff

A bit more info from the Sport Auto mag tests on the GT4: The car had buckets, PCCB but no clubsport package. Nordschleife: 7:42.4 Hockenheim: 1.10,1 Power: 385 PS @ 7175 rpm, 447 Nm, on a Maha dyno at 14° air temperature, 19° intake temperature Weight: Weight with full tank and 75kg driver: 1454 kg Weight distribution without driver: 44,6% front/55,4% rear the article also has full corner weights with and without driver. Conditions: 9°C air temperature, 17°C road temperature, 1019 mbar air pressure: 0-40 km/h: 1,6s 0-100 km/h: 4,5s 0-160 km/h: 9,3s 0-200 km/h: 14,5s 200-0 km/h: 4,7s =total time: 19,2s (GT3: 16,6s, 996 GT3 RS: 18,2s, 991 C2S: 18,8s) downforce at 200 km/h: 12kg front, 31kg rear (GT3: 18/29kg) According to the article the car has more front downforce with steel brakes than with PCCBs because the rotors are smaller and allow more air to vent through the wheels wheels. Compared to PCCBs the steels have 5 kg more front downforce with the inserts and 7kg without the inserts. Haha, this is why I love Sportauto. The car had significant understeer in Hockenheim and on the Nordschleife tourist driver training laps (I find this odd - Horst von Saurma didn't do training laps... he just did one warm up lap and then went for it). They fixed it by lowering the front by 1,1 mm and a new set of MPSC2s. They would prefer shorter gearing. The shocks are Bilstein, identical to the GT3 with a new setup. The steering is also GT3 hardware with new calibration. Unless it's a corrected value, I presume that's 385PS at the wheels. Jeff

Jeff, 385 at the wheels would be very impressive, it's drag adjusted crank power with just over 320 at the road wheels. The thing I thought was odd was the cross weights which are 713kg and 666kg, normally 50:50? Ralph

 

[Motorhead]

That sounds more sensible Ralph, and in line with Porsche's claimed output; although Preuninger implied that 385PS was the minimum expected. Very much in line with standard Porsche practice. Not sure about the weights. Jeff

 

[MrDemon]

just had this email today maybe not such a long wait to drive it . "I am delighted to invite you to attend the Porsche Driving Experience at our state-of-the-art, purpose-built centre in Silverstone for your own bespoke driving experience, driving a Cayman GT4 from our dedicated fleet."

 

[Motorhead]

Excellent D! Have they indicated yet when it will be? As I said above, the PEC manager told me last month that he didn't expect to get a car before July but perhaps things have changed now that allocations have been decided. Jeff

just phoned to book , yes end of July.

 

[Tracy_Wilkins]

Question. Can the GT4 be ordered in colour to sample i e colours such as viper green rs orange riviera blue you get the idea. I think a special car deserves to be a special colour.

I wanted my Spyder in CTS and so far have been told no chance currently and very doubtful that position will change with such a limited production run [&o]

 

[MrDemon]

this, it seems no chance, and I don't like any of the stock colours !

 

[ralphmusic]

At the Osnabruck plant on Friday we saw GT4s being built alongside Cayman base, S and GTS models. Production of all Cayman is 100 per day (single shift) of which around 15 daily are GT4s. Osnabruck has a contract with Porsche to make 100 per day and it is Porsche who set the production capacity. Best colour IMO is GT Silver, it looks fantastic in the flesh.

 

[Motorhead]

Thanks for the update Ralph and very interesting to hear that it is Porsche themselves who are imposing supply restrictions. Of course, that could be as a result of suppier limitations but let's hope that Porsche are now revising requirements for next year as a result of increased demand. Jeff

 

[ralphmusic]

Jeff, Trouble is they might have to go to an additional shift but without sufficient load but when Cayene production is transferred from Leipzig next year (to allow Macan production to be increased) they might be able to economically increase Cayman production but for GT4 it would be too late. Cayene is more of a final assembly job as near finished bodies are shipped to Leipzig from Bratislava so not a huge factory load.
