The new Cayman GT4 is expected to be powerful enough to wear the RS badge; manual and automatic gearbox options mooted
9 May 2017

The forthcoming successor to the original Cayman GT4 will stick with a naturally aspirated flat six engine despite the arrival of a turbocharged flat four in the Porsche 718 Cayman.

The engine is expected to be a detuned version of the new 911 GT3’s 4.0-litre flat six.

“Natural aspiration is one of our main USPs,” said Andreas Preuninger, head of GT car development at Porsche.

“At Motorsport, we think we can achieve throttle response and immediacy a little bit better with an atmospheric highrevving engine than any kind of turbo.” He also confirmed there are no plans to create any four-cylinder GT cars.

Autocar has speculated that the next Cayman GT4 will be powerful enough to wear the RS badge, reserved for Porsche’s most hardcore models, and Preuninger dropped a broad hint that it will come with both manual and PDK gearbox options.

“The aim is to always have the choice,” he said. “Now we’ve started with that strategy with the GT3, let’s hope that it pays off.”

Preuninger also said Porsche will crack down on speculators who buy GT cars to flip for a profit rather than to drive. “If you do it, you won’t get the next car,” he said.

Does this mean Porsche will crack down on it's own dealers?

Before post-Brexit prices kick in, in about two years. Wouldn't GT6 be a more appropriate badge, to distinguish it from the 4-cyl. models?

GT4 refers to the FIA championship that the race version of the car competes in, similarly to the 911 GT3 being compatible with GT3 specs.

Oddly though, Porsche was somehow able to trademark these names and stop other manufacturers using them on their own road car versions of their race cars, hence the Aston Martin GT8 and GT12 models, which are indeed 8 and 12 cylinder, but also equate to GT4 and GT3 race specs!

Will have to wait until this season of WEC and corresponding IMSA championships are over to see if Porsche will regret not turbo-charging the new RSR race car. So far it's not been that competitive against the turbo'd 488 and Ford GT.

Surprising to me, would have thought Porsche really needed a "Halo" four cylinder car to wake up the buying public to its four cylinder range, which nobody I've met seems to be vaguely enthusiastic about ?

Also, please Porsche, if you are selling this as a Track Day car, can it be arranged that in standard form it gets through most Track Day noise tests unlike the current range ?

Naturally aspirated and a flat 6 = Good News.

All that needs saying on this one.

It is not uncommon to see buyers simply making a purchase just to make profits. Even with a high price tag, a car that is worth an investment could easily be wiped off the shelves almost immediately. This group of buyers are often categorised as non-hobbyists or enthusiasts but are simply out for the monetary returns.
