title：Porsche 718 Cayman GT4 RS Review: Is It Worth the Hype?

The GT4 RS: Breaking the Cayman’s "Glass Ceiling"

For years, a conspiracy lingered: Porsche was holding back the Cayman to protect the 911 GT3’s throne. The 2005 original Cayman was a hit, but many wondered if it would ever reach its full potential. The GT4 RS changes that.

Developed by Porsche’s GT department, this car is a love letter to driving. Andreas Preuninger, head of GT cars, credits former R&D chief Wolfgang Hatz for pushing the idea of a Cayman with the 911 GT3’s engine. The result? A 4.0L flat-six flipped 180 degrees to fit the mid-engine layout, revving to 9000 RPM and delivering nearly 500 horsepower. It uses a short-ratio PDK gearbox from the 991 GT3 RS, making it half a second faster to 62 mph than the GT4 and hitting 196 mph flat out.

Road vs. Track: Real-World Performance

The GT4 RS isn’t just a track toy—it’s usable on the road, too. The low-speed ride is bearable (though cobblestones cause some fidgeting), and the linear steering keeps the Cayman’s signature fluency. But don’t mistake it for a daily driver: the launch team handed out earplugs, and for good reason—the induction noise is raw, otherworldly, unlike the GT3’s exhaust-heavy growl.

On the track (like Estoril), it shines. The Michelin Pilot Sport Cup 2R tires (a first for Cayman) deliver unmatched lateral grip. The chassis balance is stunning—slightly spikier than standard Caymans, but forgiving enough for drivers to push limits. The PDK gearbox shifts lightning-fast, making track work seamless.

Is It Worth the Price? Comparing to Alternatives

Priced at £108k (with fully loaded models over £140k), the GT4 RS isn’t cheap. Waiting lists are long, as expected for a Porsche GT car. But how does it stack up against alternatives?

Against the 911 GT3: The GT4 RS is lighter and has mid-engine balance, offering a different driving feel. Its induction sound is unique, and it’s slightly more usable on the road. For those who value mid-engine dynamics over the 911’s legacy, it’s a no-brainer.

Against the Audi R8: The GT4 RS is more track-focused and has a more engaging driving experience, though the R8 offers a V10 engine and more luxury.

Toolbox & Action Guide

Immediately Actionable Checklist

1. Test drive both on road and track to feel its dual personality.
2. Inquire about waiting lists at your local Porsche dealer early.
3. Consider optional carbon ceramic brakes for track use (reduces weight and improves stopping power).

Conclusion

The Porsche 718 Cayman GT4 RS isn’t just a Cayman—it’s a game-changer. It breaks the "glass ceiling" of the model line, proving Porsche isn’t afraid to let the mid-engine car compete with the 911 GT3. For driving enthusiasts who want raw performance, usable road manners, and a unique sound, it’s worth every penny.
