If you’ve ever wondered what would happen if Porsche put the prodigious naturally aspirated 4.0-liter inline-six from the latest 911 GT3 behind its mid-engined little brother, the Cayman… the GT4 RS is your answer. It’s Porsche’s GT department letting their hair down, saying “grab my Stein!” and produces the car we’ve all dreamed of, but never thought they’d have the nerve to put into production.
Yes, it’s the toughest, most powerful, all-consuming Porsche Cayman ever made, but with the new 911 GT3 already out there and a crazy GT3 RS coming later this year, its mandate is a bit different. According to Andreas Preuninger, head of Porsche’s GT department: “It’s about time for a big party on the 718 platform. This car is a live concert on four wheels, it’s a lot of fun and it was such a fun project to do.” It is something that comes from the heart and that we wanted to do for a long time.
Isn’t that stepping on the GT3’s toes a bit?
We can see why you might think that. At £108,370, the GT4 RS is around £15,000 cheaper than a GT3 with the same gearbox, 20kg lighter, just six seconds slower around the ‘Ring, has an identical 0-62mph time and has the same number of seats with a roll cage behind you (if you check the box for the free Clubsport package, which is what you need). But Preuninger insists they are completely different beasts: “We’re keen to give the GT3 everything we can to keep it in the lead, like the double-wishbone front axle, the steered rear wheels. On the GT4 RS, we don’t lean too much for the super aerodynamics and the last tenth of a second on the track. We tried to find the perfect balance between driving on the road and on the track.
Numbers, give me, give me…
We’ve got 493 hp (that’s 79 hp more than the standard GT4, but 10 hp less than a GT3 due to the exhaust having to take a more tortuous path around the rear suspension), while torque is up slightly to 332 lb ft. and that’s just PDK – according to the “RS” doctrine. There is no manual gearbox here. Boo. Still, 0-100kph takes 3.4 seconds (a GT4 with PDK takes 3.9 seconds) and top speed is 195mph. Perhaps more impressive is the lap time at the Nürburgring (with optional Michelin Pilot Sport Cup 2 R tyres) of 7 minutes and 4.511 seconds, more than 23 seconds quicker than the standard GT4… which is light years away from the ring.
Any other tricks up your sleeve?
Errrr, this is easily one of the most solid cars we’ve ever driven. Shredding a GT4 RS is like pouring thick molasses into your ears…and then a whole colony of wasps piled on top. It’s just ridiculous. And every 9,000-rpm trip isn’t just sound, it’s laced with sucks, vibrations, rattles and adrenaline rushes. A low-end buzz that hardens in the mids and becomes silkier until it breaks into a frantic shudder between 7,000 and 8,000 rpm, before a magnificent ear gas for the last 1,000 rpm that makes the soul sing and the muscles hurt. facials.
And that’s right when you’re chasing the red line. The rest of the time you have a musical instrument to play using your right foot on the pedals and your fingertips on the paddles. Normally I’d chastise anyone who thought removing the infotainment system (a free option) in the name of saving a few pounds was a good idea, but here it might make sense. Who needs infotainment when you can summon thunder with the throttle?
And that’s not even the best part. With most fast cars, the best sounds come from the tailpipes, which may sound wonderful from the cockpit, but you know it sounds even better to whoever you just passed. In effect, you are providing a public service. But not here, because what you’re hearing is induction noise from the carbon fiber air intakes where the rear windows normally sit. So while it’s a rock concert at eleven for driver and passenger, it’s no more antisocial outside the car than a standard GT4. It’s a trick that Singer has implemented to great effect on the DLS, but it’s a car that costs around a billion pounds more.
What’s the verdict?
Does the world really need a GT4 RS when we already have a tougher than ever 911 GT3? Yes Yes; God, we’re glad this car exists. With a fully electric Cayman on the horizon, it’s safe to say Porsche’s GT department feels the demise of the combustion engine and wants to build these kinds of cars while they can, these monuments to what’s possible when extraordinary engineering is combined with a bit of fun.
Porsche doesn’t limit the number of GT4 RSs, only the time it builds them, so get in while you can. Insanely fast on the trail, surprisingly usable on the highway, and a sonic feel throughout. Believe the hype…he’s likely to become one of the greatest of all time.
