for those waiting...looks like the official launch will be a Goodwood! 


Next Porsche Cayman GT4 due this spring




The latest version of Stuttgart's midship sports car will use a 420hp 4.0-litre flat six


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.
