New Porsche 718 Cayman GT4 RS set for November reveal
New video shows first RS-badged 718 conducting final testing on the Nurburgring
Porsche has confirmed that it will launch a hardcore 718 Cayman GT4 RS, releasing a video of the machine conducting final evaluation testing on the Nurburgring.
Several development mules of the hardcore version of the latest 718 Cayman GT4 have already been spied testing on the German circuit. Porsche will reveal the machine, the first 718 to carry an RS badge, next month.
Porsche claims that a lightly disguised production version of the new 718 Cayman GT4 has lapped the 12.9-mile Nurburgring in 7mins 9.300secs. On the shorter 12.8-mile version of the circuit Porsche has previously used for development the model achieved a claimed 7mins 4.511sec lap, which the firm says is 23.6 seconds faster than the regular 718 Cayman GT4.
The laps were completed by test driver Jorg Bergmeister, and the car was fitted with a full racing seat and optional Michelin Pilot Sport Cup 2 R tyres.
Andreas Preuninger, Porsche's GT model line boss, promised that that new model has "everything that characterises a genuine RS: lightweight construction, more downforce, more power and, of course, an even higher level of responsiveness and feedback to driver inputs."
Porsche has revealed no technical details of the machine, although both the new official images and previous spy shots showcase a number of bodywork additions for the RS.
At the front, there are versions of the Naca bonnet air ducts similar to those on the 911 GT2 RS, while the rear quarter windows have been replaced by slatted cooling vents. Blanking plates at the front suggest the hardcore Cayman will gain similar wing-mounted air outlets to its 911 GT3 RS sibling.
A large, bespoke rear wing – significantly larger than that of the standard GT4 - appears to be mounted higher and to use a new mounting design. Also changed over the standard GT4 are the wheels, which forego the traditional five-lug pattern in favour of a motorsport-inspired centre-lock mechanism that hints at the car's track potential.
The man in charge of the 718 and 911, Frank-Steffen Walliser, told Autocar at the Frankfurt motor show in 2019 that he would “definitely” like to see a faster and even more focused RS version of the new 718 Cayman GT4 but that the decision hinges on prioritising development resources within Porsche.
“Everybody’s asking for the RS,” Walliser told Autocar. “Can I imagine a GT4 RS? Sure I can. That’s not to say we will make a decision on it yet, as it is a challenge. Would I like such a car? Yes, definitely! Would I like more horses? Yes. But we need to put the resources where the market is; it would be a lot more expensive than the normal one.”
Porsche has never made a GT4 RS, previously suggesting such a model would be too close in price and performance to 911 GT models. But the new 4.0-litre flat six found in the latest GT4 forms part of an all-new engine family, and it's expected that Porsche will spin off further variants of that unit to justify the investment.
It's understood that the brand is looking to reintroduce the flat six to more mainstream Cayman and Boxster variants as part of a facelift. Although Walliser would only confirm that Porsche has “started the thinking process” on this, he acknowledged that the US market has been less welcoming of the current four-cylinder models than hoped. “American customers aren’t asking for four cylinders, they're asking for four litres,” he said.
While Porsche is working on a new electric equivalent to the Boxster, speaking in 2019 Walliser downplayed speculation that it would join the glut of newly launched electric hypercars with its own take on the formula, however - for the time being, at least.
Pouring water on the claims made by manufacturers such as Rimac and Lotus, Walliser said: “We've seen a lot of studies of electric hypercars. For me, the proof is when it’s on the street with a licence plate. Does an EV hypercar work? It’s like saying to me that a drag racer is a suitable sports car. For sure it’s perfect from 0-100, but to make it usable and do several laps of the Nürburgring wouldn't work with the technology at its current state.”
Walliser did welcome the idea of using hybrid technology to extend the life of Porsche’s widely celebrated naturally aspirated GT engines. “A hybrid for sure with a normally aspirated engine works well together," he said. "The low-rev electric motor torque and high-revving normally aspirated engines fit perfectly. It could help to keep a normally aspirated engine to survive, and we're very motivated to do so.”
