Ah, the simple task of developing and launching a Clubsport based on a road car. Seems more difficult the other way round

Cayman GT4: Where are we up 2 now? Déjà vu Edition
- Thread starter ralphmusic
- Start date
I refer to my previous post...............getting interesting...........Bilko1 said:Ref your last line above - precisely my point in my post last night, and quite the opposite possibility to that which Jeff suggests in the last para of his last post above. I think the loose racing/homologations rules allow the GT4 road car (if there ever is one!) to be different to the 2019 clubsport. My money is still on a turbo due to emissions. I'll leave my drivel at that.ralphmusic said:The regulations have been somewhat of a puzzle changing each year from 2016 in subtle ways. In 2016 when SRO first started to really promote the series, homologated cars included a 997 GT4 Cup Car model and the 3.4L Cayman Pro 4 from Pro Sport (which won in 2016). Neither of these could be called production cars.
The 2018 list of SRO approved eligible cars with RACB Technical papers can be found for now at least at https://european.gt4series.com/gb_en/cars
It is entirely possible within 2018 Regs (1.2, 1.14, 2.2, 3.3 as examples) for Porsche's base Trackday 718 GT4 Clubsport to be the homologation base car. (it can be bought by the general public).
Therefore shock/horror the road 718 GT4 can indeed have a different engine than the race car because it is not the homologation base car... hence the screaming and the gruff mules.
More journalistic fluff but here's the latest from Car mag:
https://www.carmagazine.co.uk/spy-shots/porsche/porsche-718-cayman-gt4-spy-photos-specs-and-info/
Kacher normally has his ear to the ground on Porsche matters, so what he says is reasonably credible. Second generation GT4 to be released at the Goodwood Festival of Speed in July with PDK available in the second wave and a 50kg weight saving? All quite possible.

If it is £90k base, that will kill it IMHO, mind you it won't have centre locks or save weight so some hope on £s
The PDK rumour is interesting, but
will it be a known post first batch/year 2 option, or
a rumour at launch?
Given my car's spec, what to do assuming price is within the non-journalistic range?

Hmm....a difficult one Ralph. PDK would add circa £2.5k to the base price and most buyers seem to add another £10k or so of options. Will an £85k 718 GT4 give you significantly more than your modified 981 CS - who knows?
There's still too much speculation at present and no information about availability and allocations. Fortunately you don't yet have to make a decision, so kick it down the road for the moment like the rest of us who have an interest.

The 718 GT4 engine/PDK/pricing saga is getting more like the wearisome Brexit with each passing week.
Kicking the can down the road sums it up pretty well Jeff......

The mags/forums are again wetting their knickers about this:
https://www.pistonheads.c...ring-pack-update/39569
Always a possiblity I suppose but I'm not yet convinced. It just looks like a standard 718 body to me (no bonnet or side scoops) with the GT4 diffuser and exhaust arrangement, so who's to say it's not just a development 718? If I can find the original video clip (at the 'Ring?) I'll see if I can get my friend to run some analysis to confirm whether or not its got the 6-cylinder engine.

I already have one of those!
We've seen GT4s with the 718 GTS front end before, but they've always had the rear wing. This spy shot Cayman has no rear wing, GTS front end, GT4/Spyder exhaust/diffuser and in one pic I've seen there was a roll cage visible in the rear. Definitely not a normal Cayman.
The Boxster version has a normal roof, not the Spyder one, but the GT4/Spyder exhaust/diffuser.
I posted on PistonHeads saying that it looked like there could be Touring versions of both the Spyder and the GT4. Looks like people are taking my comment and making articles out of it, however there's definitely something in the works...

Ha! Maybe you should be offering your services to some of the mags Dave - I'm sure you could make a better fist of it than they've done so far..!
I find it rather amusing that we're dicussing more 718 F-6 variants when we haven't even got the GT4/Spyder spec and don't know the production schedules, etc. Unless sales of the F-4 engine cars drop off significantly, will Porsche actually have the capacity or time in the 718 life-cycle to produce more F-6 engine variants?
Are these the clips about which people are getting up a lather? https://www.msn.com/en-ca/autos/autossports/listen-to-these-mysterious-porsche-718-test-mules-on-the-nurburgring/ar-BBQRJKo
Just to point out firstly that the Cayman sounds as though it's running with a PDK 'box so it may just be a developmemt mule; and secondly that development cars are often fitted with roll cages, especially if they're used a lot for high-speed testing (a health and safety thing), so maybe we shouldn't read too much into these sightings at the moment.

Here's the latest rumour:
Its a 4L in four HP configurations.
- 370-380hp Boxster/Cayman 6...yes, that is what its called, 718 Cayman 6.
- 425hp GT4 manual only
- 485hp GT4 RS late 2020 or early 2021. PDK only. Very limited car
- And somewhere in between they will squeeze a special Boxster Anniversary with possibly 450hp.
A 718 Cayman 6? Seriously?

Dave,
I saw this referenced on Rennlist from some obscure site. You couldn't make it up could you?
Even allowing for the fact that it would help amortise the cost of engine development, for Porsche to offer a 6-cylinder 718 would fly in the face of what they've been doing with the 4-cylinder turbo, a clear admission that they've got it all wrong.
Incidentally, with the race car I don't recall any mention of 718 engine bay body modifications being required to accommodate the n/a F-6? The last GT4 had some additional stiffening applied to the 981 BIW but I assume that was done as a separate operation after body assembly.

You could be onto something here. I've just been looking at the Taycan again, and the electric powered story may turn out to be a ruse to hide the fact that it will actually be a flat 12 stretch wheelbase 718 limousine...snowy999 said:Will they be welding two flat sixes together a la 917 and call it the 718 Stretch Cayman 12 with 900hp.
You heard it here first!

I can fully understand the excitement and speculation arising from these latest clips of the test mule Boxster and Cayman at the 'Ring. A tantalising glimpse of what may be in the pipeline.
Porsche definitely seem to be testing both engine configurations, 4-pot turbo and 6-pot n/a, on the test mules. They also seem to be testing exhaust system configurations.....
For my tuppence worth, I still believe Porsche will use a development version of the 4-pot turbo in a future 718 model. I know from my own experience so far with my 2019 Cayman GTS, Porsche have indeed tuned the exhaust sound. It's definitely an acoustic improvement on the first generation 718 Cayman S.
