Porsche Cayman GT4 to get Touring pack: Update!

Latest flat six-powered 718 GT4 has been seen with a retractable rear wing



UPDATE - 11.02.2019

With the new Cayman GT4's anticipated launch fast approaching, Porsche engineers have shifted their attention to the development of a second variant, which is expected to join the regular car shortly after it goes on sale this summer. In a move that mirrors the 911 GT3 line-up, the GT4 is due to be offered with a more discreet Touring Package, which does away with the regular car's fixed rear wing for a retracting one.

While Porsche has remained tight-lipped on such a variant, our spy snappers have captured images of a test car that fits the bill. It's a 718 Cayman wearing the upcoming GT4's rear diffuser, which pushes its twin-exit exhaust pipes apart. Need more proof? Our snapper said there was no doubt that the engine nestled within this Cayman was of the flat six variety because of the lovely noises it made.


Don't be fooled by the rest of the car's bodywork, which looks to be identical to lower 718 models, because we can expect the GT4's more aggressive aero pieces to be retained on the finished car. And while we've yet to catch a glimpse of its interior, our best guess is that the GT4 Touring will follow suit of the 911 GT3 Touring and swap Alcantara for leather and cloth.

Our snappers have also seen a 718 Boxster running with what looks to be an identical rear end, sans fixed wing, which suggests engineers are at an advanced stage of development with the Cayman GT4's sister car, the Boxster Spyder. Like the tin top GT4, the convertible will stick with a flat six, although the Spyder's chassis setup will be unique due to the structural differences of the two models.

We shouldn't have too long to wait before all of this becomes official, because the GT4 is due for reveal in the spring. If some admittedly hopeful sources are to be believed, we might even see it at Geneva next month...


ORIGINAL STORY - 05.02.2019


Porsche's GT department is lining up the fastest and most focused Cayman yet for arrival ahead of the Goodwood Festival of Speed this July, where the GT4 will make a dynamic debut in all its 4.0-litre flat six glory. PH has learned that the car will be revealed statically before then, but it'll be the Duke of Richmond's driveway which provides us with the first chance to hear how its new 911 GT3-sourced motor sounds.

As much as we'd love the GT-built six to rev as high as 9,000rpm, like it does in the GT3, we're expecting a few hundred revs to be chopped from its top-end along with a 15 per cent decrease in peak output to about 420hp. Still, a mid-engined sports car that revs to, say, 8,500rpm and can hit 62mph in about four seconds doesn't sound too bad, does it? Especially when it's due to come with a - rejoice - manual gearbox as standard. Sure, a PDK auto is due to follow, but there's nothing like three pedals and lever to signal a manufacturer's intent when it comes to producing a proper driver's car Mk2.

 

The rest of the new GT4 will be an example of evolution rather than revolution, unsurprisingly, so expect more lightweight tech to be employed within its chassis, including exotic metals in the suspension and wheel hubs, as well as lightweight forged wheels. Spotted test cars have worn even more aggressive external aero pieces, the most prominent of which is a larger fixed rear wing, but there's also a new front lip and the diffuser splits the two pipes of the exhaust system. Inside, the cabin is expected to stay largely the same as the regular 718, barring GT bucket seats and swathes of Alcantara.

Numerous sightings of the GT4 at the Nurburgring suggest Porsche could also announce a new lap time when the car is launched - it is a 21st century sports car after all. While the GT4 isn't going to blitz it to the top of the Stuttgart leaderboard - that title will probably be held by the 911 GT2 RS and its 6:47 for quite a while - given the rate of the GT department's development, we could be looking at a big improvement over the old 981 model.

Unlikely to spin to 8.5k. More like peak power high 6s or low 7s and cut out below 8k. Won't get within 1,000rpm of the GT3 lump, I don't think.

Love my previous generation one and it got used properly - not in the market for this type of car at the moment but hope plenty of them get used rather than just speculated on

Cool.

Although anyone wanting one who doesn't buy lots of Porsches, or isn't a Vlogger / speculator won't stand a chance of getting one.

Up for sale straight after on Pistonheads / Auotrader with a £40k premium.

Isn't second gear good for 110mph or something?

More like low 80s at the cut out and given a GT4 is pretty flat above 6,000rpm, in reality you're shifting in the 70s. Not ideal, but not 110mph either!

Exactly! The usual. Porsche: just make more of the damn things.

If it's the same basic block then a visit to Manthey or the like would soon see the full potential from the engine released.

My Porsche drivers dream. Unless they make the rally version wink

Hope some extra effort is done to keep it light, too.

Obviously it won't have to rev very high to make the claimed power, which isn't the same as it won't be able too... More than 8k rpm at least is my guess.

I read on Rennlist it's an enlarged version of the 3.8 as opposed to the GT3 engine.

What's the actual source of this information or is it pure speculation once again? Does anyone actually know what's going on with it?

they tend not to mess with oem engines now days, might be a Porsche thing as they now own 51%

all of the new cars get the same stuff, more aero, a set of 3 ways shocks, and a proper geo.

Porsche cannot have Manthey making GT4 beating GT3

I suspect it will use the basic 4.0 bottom end from the 991.2 GT3 with the heads and other gubbins from the existing GT4.

Suspect it will be the heads not the block that are the limiting factor!

I may need to give my dealer some credit after all. Whenever I ask about the GT4 they never sound too sure of themselves, but so far they've been right every time.
They told me 4.0l 420hp back in September. And last month they told me orders would open in May, manual first, PDK to probably follow later.

Would love one, but you'll be hard pressed to get one now and the prices will be only going one way... I understand the business reasons for not making as many as they can but Porsche can afford some integrity to the performance market, especially as their profits mostly come from their SUV range.

420bhp sounds remarkably like the old 3.8 991.1 GTS lump (430bhp) plus a particulate filter.

They might go for the GT3 motor, but it seems way overkill as a way to 420bhp.

The hype ensuing from the bunfight to get hold of one of these cars in terms of how desirable it makes the brand look is pretty priceless in promotional terms. Can't see them changing anything.

What's more, there's a fair bit of economic uncertainty both in the EU and the US, so now could be a bad time to finally decide to up production massively. That said, Porsche has actually increased the production of its GT cars enormously, they just haven't talked about it! They built more 991.1 GT cars than all the previous 996.1, 996.2, 9971. and 997.2 iterations combined. And then they made loads of 991.2 GT cars, too, plus the original GT4.

There's already a massive glut of barely driven late model Porsche GT sitting in storage facilities in Europe and the US. At some point the party will end and I think Porsche is right to not go completely crazy on the supply side. It's all going to come to an end anyway, but massively upping the production of these cars could make that ending more abrupt and painful, which is pretty undesirable from a branding perspective.

In the end, the problem isn't Porsche, it's all the punters buying these things and then not using them. It's a nonsense, but it won't last forever.

Except that motor is / was a 3.8m not a 4.0.

I agree the old 3.8 powerkit motor has always seemed like a no brainer for the GT4, right from day one. But /i fear '4.0' sounds better than '3.8' and being able to imply it's derived from the GT3 lump even if it shares little of real consequence is marketing gold. 4.0 is simply better than 3.8 in marketing terms.

Agree entirely with your comments. I've got a 991.2 GT3 and have done 5000 miles including some daily commuting - it's there to be driven and enjoyed not just to be tucked away in a garage.

Just what the Porsche section of the forum needs. Another GT4 article full of unfounded speculation!
