Porsche 718 GT4 RS spied! ultimate Cayman tests at the 'Ring

► 718 Cayman GT4 RS spied after Porsche hints
► Bosses confirm there's room for an RS
► Details, likely power, pics

Earlier this year, our colleagues Down Under at Wheels magazine in Australia have fleshed out the details of a potential 718 Cayman GT4 RS, after interviews with top brass in the Porsche GT department. But now, we can reveal new spy shots of the 718 Cayman GT4 RS testing at the 'Ring.

We've already fallen for the Porsche 718 Cayman GT4 hook, line and sinker, so images of an even more focused RS version has set tongues wagging.

Andreas Preuninger, who heads up the GT department, admitted there was potential above the GT4 for an even more focused road car. 'There’s always room, if you create the room,' he told Wheels. 'There are lots of ideas that we have at the moment, and the good point is we have a lot more ideas than we can really carry out and realise. But I would say, yes, sure. Stay tuned on this channel.'

The pictures above show he's making good in his promise. YNACA ducts at the front of the mid-engined GT4 RS snatch air for brake-cooling, and Porsche engineers are also funnelling extra air into the uprated flat-six with louvres in the side rear windows. It's a mean-looking thing, and the effect is only multiplied by that huge testing-spec wing on the back. 

We'll update this article when we know more.

Porsche 718 Cayman GT4: more potential from 4.0 flat six

Porsche's engine guru Markus Baumann said that pilfering the GT3's parts bin would liberate tech to take the GT4's flat six even further. Adding a dry sump, new valvegear and titanium internals would 'enable this engine for more power and more revs,' he added. Chassis mods would be likely to include new tyres, race-spec suspension components and new aero fixtures to create extra grip in corners.

Preuninger warned that this confection of high-tech parts would considerably raise the price of a potential GT4 RS over the regular car (above). 'To give this engine more RPMs, you give it more components that become really costly,' he said.

This alone poses a marketing - and ethical - conundrum for Porsche. It wouldn't want to push the Cayman too deeply into 911 territory. And it's already copped some flack for increasing the price of the new GT4, which rose from £64k to £75k in the UK.
