The Cayman GT4 now bears the RS badge which can only be a step towards insane performance or even just enter that arena. With this release, the question would be which cars will this GT4 RS dance with since it levelled up into a prime league. Let me put it this way, it has the same engine from the 911 GT3, a 4.0-litre naturally aspirated flat-six, it’s 20 kilograms lighter than the PDK spec 911 GT3 and it is about R600 000 less than the aforementioned Porsche model. On top of that, it set a nurburgring lap time of 7:04.511, which is just shy 5 seconds off the 911 GT3.
Straightaway, the Cayman GT4 RS establishes itself as a hardcore track weapon when you take a first glance at it. On the front is an exposed carbon fibre hood with cooling inlets for the brakes, on the bottom is a front lip that is connected to the side air curtains and this almost looks like a beard with sideburns. The front wheel arches have vents, the front diffuser is manually adjustable, there is underbody aero, a rear diffuser and a large fixed rear spoiler. All of these components contribute to a 25% increase in downforce over the standard GT4.
The suspension was not spared at all because with all that downforce requires specific RS shock absorbers, bespoke anti-roll bars and springs, plus ball joints that stiffen the car to be closer to the chassis and increase rigidity.
It is even significantly lighter than the standard Cayman GT4 with the replacement of the windshield for a thin Gorilla glass, there’s a titanium roll cage that comes with the Weissach package, a titanium exhaust system, lighter door panels, door storage nets and less insulation. All of this makes it 34 kilograms lighter in comparison to its standard self.
The engine is not just a tad more powerful but it produces 79 hp (59 kW) more power than the GT4, 493 hp (368 kW) to be exact and 450 Nm of torque. The engine revs all the way up to 9000 rpm and it has the 7-speed PDK transmission for company, no manual gearbox option available. It manages to do a 0-100 km/h sprint time of 3.4 seconds with a top speed of 315 km/h.
We were wondering why it took so long for Porsche to even consider an RS model for the baby 911 and this creation is thanks to factors that included customers bidding for it to made and the silencing of engines by this phase called electrification. You might find it interesting how the Taycan is mimicking the Panamera by having the same model variants as it, which might lead to the replacement of the ICE car anytime in the near future. So an RS model is a form of a send-off by the manufacturer and it is quite touching.
