Cayman GT4: Where are we up 2 now? Déjà vu Edition

[MrDemon]

Today's Autocar (reach for tin hat), hints at a forthcoming 718 Boxster Spyder, Cayman GT4 and Cayman R, all running detuned N/A 4.0 991 GT3 engines of varying power (420 for Spyder and GT4). Manual and PDK available on each....

All old rumors/news and it will not be a detuned GT3 engine, it will be a stroked 3.8 base engine to give a headline 4.0 badge. They are not fitting a £50k engine in a £60k car lol wishfull thinking though.

If it were to happen with a GT3 engine they will be the bargain of all time.

Or expensive ... but then, where is the gap in the market ?

Yes D, yet more regurgitation of the same old stuff by the mags in the light of no information forthcoming from Porsche (surprise, surprise!). In my book Georg Kacher (CAR, Automobile) seems to be the only one with his ear to the ground when in comes to extracting (reasonably) reliable information from them.

I think that we've said it all on here about what to expect from the next GT4 version, with the exceptions of transmission options and maybe some additional suspension adjustability. I may be wrong but at best I can't see anything appearing until later this year; more probably Spring 2019 if Porsche are planning coincident releases of the GT4 and Spyder (who would want a rag-top for the Winter?).

I would want the new one to:

A: heat up faster on the oil, my 981 GT4 and Spyder both take 7 odd miles, my new GT3 takes only 2 to 3 !!

B: do way more MPG, I got 12 on a fast run out and less than 6 on track !!!

C: have proper adjustable sus for track use

D: Have much shorter gearing

E: have an engine which keeps making power to red line not stops at 6k and then dips like a ******

F: Still have the option for the older 997 GT2 buckets, or have modified 918 style with better rake and heated.

G: ideally have a co2 lower than 225 other wise it's >£2k to TAX a new £70k car which is just mental in this price bracket when one can buy 500bhp cars now for 1/2 the tax cost !!! H: have at least the new GT3's eps system and feel.

It's a given the new tech will be in the car like Apple car play etc but the GT4 had too many flaws in the gen1 and was a bit over hyped imo.

Porsche can fix all those things very easy for very little cost and give us something really to shout about, but will they hold it back yet again !

The manual GT3 is perfect so far, I am loving it and cannot find an issue ! or mod I would do , the only issue is the cost of it, I could cope with less bhp if the car was £90k all in but had all the fixes above.

But I have driven the GT3 on track and boy it's night and day better than the GT4 in so many areas, which I guess you expect for the cost I guess.

It also makes a far better and nicer road car, so no track down sides and no road downsides !!

Also the new EPS is at last totally perfect, I cannot fault the GT3 EPS, no middle play what so ever and you can feel the change in the road surface via the wheel at last. I drove the GT3 at over 100% with total ease on track it gives you every thing you need to take the car over 100% levels of grip.

How close will Porsche let the GT4 get to the GT3 that is the big question. I bought my GT4 because there has not been a manual GT3 for 5 or 6 years the 991.1 GT3 held zero interest for me.

The Manual 991.2 GT3 blows me away in every area. it really is driver perfection and that's high praise coming from fussy old me I tell you.

David, I'm really pleased to read that you are enjoying your car.

I do love Porsche, even when they mess you and me up !

Any chance of a passenger ride ?

 

[MrDemon]

Any time, you can have a drive if you wish.

Useful info on your GT3 D - good to hear that you're pleased with it. Sounds as though it's a big step up from the GT4 - as you'd expect for the price..!

Re your "wishes" for the GT4:

A. Maybe this is due in part to the difference between standard and Sport mode settings where the oil temperature is lower in the latter? Also the GT3 uses a dry sump system so the oil supply/cooling systems are totally different.

B, E and G. This is very much down to DME tuning - conflicting power, fuel consumption and emissions trade-offs.

C. I'm sure that more rear suspension adjustability is on the cards - shouldn't be too difficult or expensive to achieve.

D. I think shorter gearing is highly unlikely - too expensive to implement on a (relatively) cheap niche car and the next version will have more torque, negating the need for shorter ratios (in Porsche's eyes!).

F. The buckets were available in the last version, so I'm sure that they'll be an option the next time round. The 918-style bucket seats seem to have both supporters and detractors - try before you buy perhaps? What have you got on the GT3?

H. Given that they share the same front ends I'm sure that there's no reason why the GT4 shouldn't get the latest GT3's EPS rack and tuning.

With a likely base price-point around £70k I'm not setting my expectations too high - just incremental improvements, Porsche style.

MrD has folding buckets in his GT3, Jeff.

 

[ChrisW]

And they are very comfortable.

In the GT4 the Clubsport option was only available with the 918 seats ...

Good to hear you are enjoying your GT3 David.

Going by your comments, it's a perfect driving machine for sure, and the evolution developments having gained your approval is a rare occurrence on this forum [].

I always have a list of things to do, a wish list ,but it's too good this car really blown away by it. In the world of PDK and turbo's it's amazing we have this car at all. I might do a few things later monoball rod ends, ti bypass pipes, BBS forged wheels, just for fun not because it needs anything. I am so happy that the EPS is so goooooood

I would say the only negative is tyre road noise on bad roads, that's it.

David,

I've just read the GT3 article by Matt Master in the current issue of PP. You are a very lucky man to have the satisfaction and joy of owning such a fabulous driving machine. I thought Matt put the case for the manual gearbox extremely well. I absolutely agree with his comments as to why the manual gearbox suits this GT3. Yes, the PDK versions are faster on the track if lap times are your thing, but for pure tactile involvement with this glorious 4.0 engine, the manual version is a perfect choice.

As you well know from my posts on this forum, I'm a manual gearbox enthusiast of long experience. The reason I migrated to PDK was purely on account of my right hand disability. I'll always be a manual enthusiast at heart.

Were I healthy and wealthy enough to afford a GT3, I would also choose the manual version, because the physical connection to that amazing engine so eloquently described by Matt Master in his article, makes this particular GT3 a pure driver's machine.

On my forthcoming travels south in July, I am including an afternoon track day session at Donnington on July 24th. If by any chance you are also attending that event with your GT3, I'll be joining the queue for a passenger lap....

Back on topic, there's a lot of fluff on other sites regarding the fitment of gasoline (petrol) particulate filters (GPF) possibly having a detrimental effect on performance. Whilst Porsche probably could meet the more stringent particulate requirements being introduced this September without GPF, as a safety net it seems most likely that they'll feature on all petrol engined vehicles when the lines are reopened after the annual shut-down.

The GPF will introduce only a minimal additional backpressure (something like 0.1lbf/sq inch I believe for a clean GPF), so it's effect on performance is likley to be minimal and offset easily by a DME tune bearing in mind the fact that the engine won't be let off the leash by Porsche anyway. More problematic could be the packaging, with the limited space available and relatively short exhaust pipe runs - will they use a single GPF or have a GPF for each bank? It will be interesting to see what's lurking behind the GT4's bulky rear diffuser..!

Oddly enough it's the introduction of direct fuel injection on petrol engined cars which has led to need for GPF. Although offering improved fuel consumption and reduced emissions, the downside with direct injection is particulate emissions, which traditional indirect fuel injection petrol engines don’t produce. The plus side is that the GPF is very effective at capturing particulate matter (~99%), doesn’t increase fuel consumption and is simpler than a diesel particulate filter because it won’t clog up in urban running as the exhaust from a petrol engine is hot enough to allow the filter to clean itself without any extra help.

So that's all good then..!

Jeff,

Do you have to post informative stuff, it’s not really what forums are for. (lol)

Given tampering with diesel emissions equipment is an MOT failure, I wonder if the same will be true of the petrol particulate filter and the effect on the modified exhaust business.

David,

If you are doing Donnington in July like Brian I would love a passenger ride and would like to join the queue.

Now we are living in Devon its a bit of a trek to anywhere but having family still in Leicester and Nottingham its an excuse for a ride up.

Really pleased your enjoying the car and your the only person I know who has gone manual, I have 5 friends who I go for regular drives with who have all gone PDK. Don't understand it.

Will have to wait 4 or 5 years until they get to sensible money.

Not got any track days planned, was not going to keep it long term but it’s that good i need to find a way to pay for it now was not expecting it to be this good.

i agree it’s odd most have automatics. That’s a great shame and their loss imo We live in a time where there is a big choice if you want an auto and if I did I would have to try a AMG GTR , I love that car and of course below list 2nd hand.

will we see manual Club sports get to sensible money ? It's a rare car so it might never happen, the only other 4.0 manual GT3 is £500k

be interesting what they do with the new 992 GT3 as the markets flooded with PDK GT cars now, not enough buyers at these prices.

so I guess prices will go hand in hand with what happens with the 992 And every thing could quite easy drop back to below list, unless we have bigger duty to pay on German cars soon And the next GT3 might well be £20k more expensive any way Due to that.

Jeff,

Ha! It's tough Ralph, but someone has to do it..!

Actually this forum's pretty good when it comes to factual information. I see that PH's The 718 GT4 might be arriving sooner than you think! post is now running at a whopping 85 pages and you could probably count the number of useful posts on the finger of one hand. Why let a good post be spoiled by objectivity, eh..?

Given tampering with diesel emissions equipment is an MOT failure, I wonder if the same will be true of the petrol particulate filter and the effect on the modified exhaust business.

I would imagine that the MOT legislation will be updated quickly to include GPF. I don't know how the aftermarket modified exhaust system suppliers will react since I don't think that the MOT test actually measures particulates. Until it does, or unless the legislation prohibits it on a like-for-like basis, I presume that they can continue to produce systems without GPF provided emission limits aren't exceeded.

Mot is a joke my mates got his 1275 org cooper s on the road again now no mot needed.

odd rules for 40 year old cars !

The older they get the safer they get?????????????? Weird or what!

 

[Motorhead]

Yes, a strange rule but the argument appears to be that owners of old cars know how to take good care of them and don't use them much.

Mind you, driving an unmodified and original 40-year old car in modern day conditions could be a bit scary..!
