Take A Closer Look At The Porsche Cayman GT4 RS And Its Angry New Stuff

Spy shots of Porsche's 718 Cayman GT4 RS have emerged, giving a detailed look at what's changed relative to the standard GT4

Having been caught on video last week, the Porsche 718 Cayman GT4 RS can be examined in detail from all angles thanks to some new spy shots. It’s quite an angry little brute, isn’t it?

The first details of note are the brake-cooling Naca ducts, sitting - as they do on the 991.2 911 GT3 RS - either side of the trunk lid. The front bumper is much the same as the regular 718 Cayman GT4, although there’s a new splitter which protrudes slightly further. Best take those speed bumps slowly.

Perhaps the most interesting change is those louvres where the rear three-quarter windows used to be. We’re assuming these are to provide additional engine cooling, but what exactly has Porsche done in that department?

Dumping in the full-blown 911 GT3 engine seems extremely unlikely. Adapting it for the mid-engined Cayman would be - we’ve been told previously - prohibitively expensive. What Porsche will likely do instead is heavily work over the GT4’s ‘9A2 Evo’ flat-six.

This will probably involve the 9A2 Evo incorporating GT3 engine parts, allowing it to rev higher than the 8000rpm ceiling it’s capped at currently. Porsche’s boxer engine development boss Markus Baumann suggested in an interview last year that this could mean taking elements like titanium con-rods and dry-sump lubrication from the company’s full-fat 4.0-litre six, which is essentially a race-spec unit.

Moving further round the back, we have to talk about the gigantic rear wing. Like the 992 911 GT3, it’s a top-mount part - a design which increases downforce by cleaning up the airflow for the underside of the wing.

Inevitably - given the Cayman’s different profile - the wing diverges from the GT3’s significantly, although this won’t be its final form. What we’re looking at here is still a fairly early prototype, and details - including those very chunky mounts - may change. Just below, we can see that the diffuser matches the normal GT4’s, but again, there may be further development in this area before production.

We may see the 718 Cayman GT4 RS in full before the year is out, or perhaps in early 2021.

Looks a bit like the Factory Five 818C with those louvers - from the side, anyway.
