“We needed to make an trustworthy turbo,” Porsche’s Andreas Preuninger, who’s answerable for Porsche high-performance GT vary of vehicles just like the 911 GT3 and Cayman GT4, says, “as a result of these days turbos are likely to get modified in a manner that they really feel like 10-liter [naturally aspirated] engines, and that is not the purpose.” Preuninger’s voice hastens, like a whirring compressor. “I believe a turbo motor has so many fascinating sounds and traits… I needed this turbo to burble and overrun, to make hissing sounds of the wastegate and mechanical noises. The respiration of the engine, the way in which it builds up energy—even a bit turbo lag, why not? The GT2 RS needed to be totally different, and it’s. Huge time.”
A big a part of Preuninger’s job includes preserving the corporate’s sporting soul in roadgoing autos, which is a very important a part of Porsche’s enterprise. Get a GT proper, and you may quell the critics who say the producer is shedding the plot by constructing Cayennes and Panameras; get it incorrect, and also you danger alienating the diehards and Porsche evangelists. This time round, Preuninger went old style to create that elusive distinction: he dug into the Porsche museum assortment and put a 1970s-era 935 Turbo and a number of other turbocharged racecars on a raise, measuring issues like consumption runner lengths and the header diameters. The findings helped form the GT2 RS’s inimitable howl.
It is arduous for fans to seek out fault in Preuninger’s newest creation, at the least on paper. Although energy is just pushed to the rear wheels, the GT2 RS just lately ran a record-setting 6:42.three on the Nürburgring Nordschleife, beating the 887 horsepower, all-wheel drive 918 Spyder’s time by a boggling 10 seconds. It additionally shamed the latest file holder, the Lamborghini Huracán Performante. However numbers solely inform half the story, so we traveled to Portugal Portimão circuit to get the total seat-of-the-pants scoop on this 700 horsepower beast.
Beating the venerable 918 Spyder on the Nürburgring requires a fearsome power-to-weight ratio, hardcore engine tuning, a reworked suspension setup, and a contact of luck. As such, the GT2 RS’s weight reduction regime concerned all the things from carbon fiber bucket seats (saving round 31 kilos) and a magnesium roof (2.2 kilos lighter) to deleted rear seats (21 kilos) and the usage of carbon door hinges (trimming 1.7 kilos). Incorporating Gorilla Glass on the rear additionally did away with 7.7 kilos. Counting the lack of all-wheel drive , the GT2 RS jettisons round 300 kilos in comparison with an equal 911 Turbo S, totaling three,241 kilos. The $31,000 Weissach bundle saves a further 40 kilos and contains exotica like carbon fiber stabilizer bars, magnesium wheels, a titanium roll cage (for non-U.S. markets), and a three-layer carbon fiber roof panel; That is about $775 per pound saved, for these counting at house.
Porsche has jacked the GT2 RS’s output to 700 horsepower and 553 lb-ft of torque, a substantial leap over the Turbo S’s 580 horsepower. The Turbo S-derived variable geometry twin turbochargers now characteristic bigger generators and compressors, enabling the three.Eight-liter flat six to spin to 7,200 rpm. Upgraded bits embody the crankcase and pistons, whereas a multitube air filter sees its first use in a manufacturing automobile, incorporating 5 tubes for elevated cooling floor space. One other novel characteristic includes a 5-liter carbon fiber tank within the cargo space. The reservoir feeds water to 2 nozzles that spray the netting alongside the intercooler, decreasing cost temperatures by as a lot as 70º F. The system solely runs throughout excessive temperatures (assume 100º F + ambient temperatures), and the engine continues to function usually if the water is depleted. NACA ducts on the hood cool the entrance brakes, whereas louvers on the wheelwell extract air, aiding entrance downforce.
For the primary time in a Porsche avenue automobile, all suspension connections use metal ball joints as a substitute of rubber bushings. Dynamic engine mounts additionally assist preserve the powerplant mounted to the chassis throughout aggressive acceleration, eliminating the results of surprising axle loading.
Swing the GT2 RS’s door open and you may discover a stunning heft regardless of the in depth lightweighting elsewhere. In contrast to the 918’s surprisingly wispy doorways, the RS retains its stout, 911-based crash construction (it does, nevertheless, use nylon strap door handles, a hat tip to RS fashions of yore). Getting seated includes a little bit of a posterior dexterity; it is virtually not possible to not fall into the deep bucket seats with an ungainly plop. As soon as in place, the cockpit exudes a way of performance trimmed in Alcantara – numerous Alcantara – from the steering wheel and equipment selector to the headliner, seats and door panels. U.S. vehicles cannot be legally geared up with a roll cage, however vehicles bought by way of Might 2018 could be ordered with a stereo delete; after then, all autos shall be legally required to have a backup digital camera and, on this case, a navigation display. A/C delete is one other no-charge choice.
The ignition key turns along with your left hand, a practice Porsche has adhered to regardless of the ubiquity of engine begin/cease buttons, and the flat six growls to life by way of a titanium muffler. For the reason that RS is at all times in monitor mode, Porsche drops the acquainted manettino-style dial from the wheel. The one powertrain settings on this rear-drive monster are PDK Sport, stability management off, and stability and traction management off. In case you’re into even growlier sounds, a sport exhaust button frees additional decibels through a tailpipe flap.
Off the road you will discover a gradual ramp up of grunt that accentuates the twin-turbocharger’s energy amplifying impact. Control the digital gauge and you may discover that enhance does not actually kick in till round 2,500 rpm or so, relying on engine load. The RS feels gentle because it accelerates, however something greater than average throttle enter creates fierce ahead movement. Dip arduous into that proper pedal and the ability is immense and superior, particularly when turbo enhance thickens round four,500 rpm. Aggressive driving can shut gaps in site visitors that should not be possible in a land-based car — it is that fast. At full tilt, the GT2 RS sprints to 60 mph from a standstill in a whiplash-worthy 2.7 seconds, placing it on par with a number of the quickest manufacturing vehicles in the marketplace. Curiously, its 211 mph high pace was electronically restricted because of the tires. Porsche engineers say the totally uncorked drivetrain might hit 220 mph.
Whereas the modified 7-speed dual-clutch transmission shifts rapidly and is clean sufficient in common or PDK Sport mode for on a regular basis use. Although you may need the itch to faucet the small steering wheel-mounted paddle shifters, in computerized mode the PDK shifts intuitively sufficient to obviate the necessity to swap cogs manually. The one two instances I discovered it extra satisfying to shift manually was throughout a short downpour after I most popular being in full management of torque supply, and after I needed to appease gesticulating locals with the dramatic sounds of the crackling, wailing exhaust. By the way, my big-winged, hornet-liveried tester drew simply as a lot seen awe from the Portuguese as did Lamborghinis and McLarens I’ve examined there prior to now.
The game exhaust setting is enjoyable for a present, however customary mode is lots loud for many circumstances and might get tiresome on longer freeway drives, with an particularly irksome resonance at round 2,200 rpm. Tire noise from the Michelin Pilot Cup Sport 2s can be appreciable at freeway speeds, and the carbon ceramic stoppers could be noisy and delicate earlier than they’re warmed up. Grownup drivers will doubtless discover gripes with the GT2 RS’s cockpit racket, however given the truth that that is essentially the most relentlessly performance-focused Porsche cash can purchase in the intervening time, it is protected to say that if it is too loud you are too outdated … or one thing like that.
Although the GT2 RS presents critical shock and awe on public roads, it is higher suited to locations like the two.9-mile Algarve Worldwide Circuit in Portimão, Portugal. Chasing a 918 Spyder piloted by none aside from Lars Kern, the Porsche take a look at driver who set the lap file on the Nürburgring, reveals an amazing deal in regards to the RS’s relative efficiency limits. For starters, there’s the plain unbelievable capability for devouring straight-line distance. Engine torque is so strong that I managed to spin the tires in third gear, going uphill. Fortunately the traction management system is seamless sufficient that these transient moments of wheelspin are arduous to understand until your butt-o-meter is especially delicate, or you may have the posh of trying down on the dashboard for the little yellow traction gentle. Keep clean and even-handed with the throttle, and you will be rewarded with surprisingly compliant dynamics which talk the precise relationship between automobile, chassis, and tire contact.
One stunning facet of the RS is the surprisingly delicate and forgiving turn-in at decrease speeds, which runs counter to the RS’s hardcore philosophy. Should not a savage monitor machine have razor sharp on-center really feel and turn-in? For starters, whereas the RS’s rear-axle steer system is calibrated for monitor use (versus Turbo S, which makes use of a extra street-friendly setting) the bigger 21-inch rear wheels are so cosy within the wheel wells they countersteer about half as a lot because the Turbo S.
However here is the fascinating factor in regards to the RS’s entrance/rear dynamics: you will thank your fortunate stars that turn-in is not overly reactive as a result of the rear finish has a powerful tendency to rotate. Positive, the throttle wags the tail—700 hp and 553 lb-ft will do this, even with sticky 325mm tires. However there’s additionally a propensity for the tail to show when releasing the throttle. Quite a lot of components come into play with high-speed cornering, together with downforce (which approaches 1,000 kilos at high pace, when the RS’s rear wing is in its extra aggressive place). However a key attribute of the RS’s habits is how vigorous that rear finish can get. When requested in regards to the tuning, Kern informed Autoblog that rear camber and toe have been dialed out for better high-speed stability through the file run on the ‘Ring. We consider it, because the rear finish would have turn out to be unglued throughout arduous braking from excessive speeds on the 12.9-mile circuit.
That mentioned, the RS has extraordinarily excessive lateral grip within the dry and a surprisingly playful demeanor so long as driver inputs are delicate. A faint whiff of understeer is a welcome tendency when flinging the RS round a nook, not solely as a result of the tail is able to coming round so rapidly, but additionally as a result of it is really easy to neutralize with an additional millimeter or two of throttle. Elevate off in a high-speed nook (as I did briefly whereas hurtling alongside the high-speed right-hander resulting in the three,100-foot straight), and the tail steps out dramatically, caught virtually instantly by stability management. It took just a few hundred ft for me to catch my breath. However earlier than lengthy I used to be again on it once more, seeing an indicated 180 mph on the finish of the straight earlier than arduous braking.
It is a testimony to the RS’s high-speed stability and extremely efficient brakes that my confidence was restored so rapidly. Whereas the RS requires a bit extra approach than the 918 Spyder, which creates seamlessly flat cornering and makes use of torque vectoring to make you are feeling like a rock star, essentially the most excessive 911 is not fairly the widowmaker you may anticipate a big-winged, three,241-lb, 700 hp monitor weapon to be. Two laps in a sudden rainstorm intensify simply how manageable the chassis is. Although trying to faucet into the automobile’s full potential is an (clearly) futile endeavor within the moist, at the least the RS nonetheless manages to really feel intuitive to anybody with a assured grasp of moist driving dynamics.
The 40-minute drive house from the monitor reinforces the GT2 RS’s fearsome, centered character. Although experience high quality is surprisingly compliant for such a track-oriented automobile, the highway noise and exhaust be aware may make you would like you took the Vary Rover in your lengthy distance slog.
However that is not remotely damning for this newest, biggest monitor toy—in reality, it is precisely the form of automobile Porsche wants, since that is represents the efficiency pinnacle of their 22-car 911 lineup. If the stripped-down T is not supercar sufficient, or if the Turbo S is just too refined and smoothed out, the GT2 RS is simply nasty sufficient to fulfill your thrillseeking facet. And that just about $300,000 price ticket? Complain not, my buddy; Porsche will solely construct round 2,500 GT2 RSs, and the demand has already far exceeded the availability.
