Porsche has unveiled the long-awaited (and long-rumored) 718 Cayman GT4 RS. Powered by the 911 GT3’s engine, it is an ode to driving and engineering that was designed explicitly for optimum efficiency on the observe and most enjoyment on a twisty street.
“We did not maintain again on this one. We need to celebration with this automotive, we need to have fun the naturally-aspirated engine, horsepower and RPM as a result of some day sooner or later it’s going to flip to electrical,” defined Andreas Preuninger the director of Porsche’s GT mannequin line. He is liable for the good GT-badged automobiles that the German agency has launched lately, and he poured all of his expertise into the GT4 RS.
The area immediately behind the passengers is occupied by a naturally-aspirated, 4.0-liter flat-six engine borrowed from the 911 GT3. It makes 493 horsepower and 331 pound-feet of torque on this software. Porsche aficionados will instantly discover that these figures are barely under the GT3’s, which examine in at 502 and 346, respectively, so what offers? We went straight to the supply to search out out.
“The engine is totally GT3; it isn’t detuned. It makes about 10 horsepower lower than within the GT3 as a result of we have now an extended exhaust system now that the engine just isn’t within the again, so we lose some horsepower resulting from backpressure,” Preuninger mentioned. That is settled, then.
Porsche quotes a 3.2-second dash from 0-60 mph — a determine that makes the RS about half a second faster than the GT4 — and a prime pace of 196 mph. The engine spins the rear wheels by way of a seven-speed dual-clutch automated transmission linked to a pair of steering wheel-mounted shift paddles, and engineers made the gearing shorter to enhance acceleration. Need a stick? Not an opportunity, Porsche informed us.
“No, it is not coming with a guide. Why not? As a result of there is not any guide obtainable that we will mount within the GT4 platform that may deal with the RPM and the torque of the engine. It is not as a result of we do not need to, it is that there is nothing there. And, RS at all times means PDK. We imagine the automotive is made for the race observe and that its goal is to set one of the best observe instances. PDK is the way in which to go,” Preuninger identified.
To feed further air into that new engine, the present intakes simply behind the doorways are given a hand by a second set that fills the realm usually reserved for tiny rear quarter home windows. It is a cool-looking function that additionally creates a one-of-a-kind expertise within the cabin. High quality-tuning this function was simpler mentioned than performed; Prenuinger informed Autoblog that the primary take a look at automobiles had been “deafeningly loud” resulting from this set-up. His crew’s work paid off, and the tip result’s what he labeled “essentially the most intense acoustic expertise in a GT automotive,” which is excessive reward contemplating his resume contains prompt classics just like the 911 GT2 RS.
There’s a number of chassis wizardry happening beneath the physique. The RS notably receives a selected suspension system that is adjustable and whose numerous elements are related to the physique by way of ball joints — that is a function extra usually discovered on race automobiles in addition to the brand new GT3.
It sounds — pardon the pun — such as you’ll hear the GT4 RS earlier than you see it however it’s not precisely refined to take a look at, both. Driving on center-locking 20-inch wheels, it positive aspects a redesigned physique package that features a entrance splitter and the GT3’s swan neck rear wing. These add-ons aren’t only for present: they enhance downforce by about 25% in comparison with the 718 Cayman GT4. Porsche additionally fitted carbon fiber hood and fenders, plus a thinner rear window to maintain weight down to three,227 kilos. That is 49 kilos lower than the automated model of the GT4.
Step inside and, despite the super-Cayman’s ambition to rule the observe, you will not really feel such as you’re in a 24 Hours of Le Mans racer. Passengers profit from all the consolation and know-how options patrons count on in a automotive in 2021, together with a touchscreen-based infotainment system with navigation, in addition to air con. The seats are fixed-rake carbon fiber seats with extraordinarily aggressive bolstering, however they’re obtainable in loads of different Porsches, together with the GT3 and common GT4. There are some bits that set the RS aside, together with a tachometer with a 9,000-rpm redline and cloth door pulls, however Porsche’s goal was to make a automotive that is additionally fulfilling to drive on public roads.
All informed, the GT4 RS is greater than the sum of its elements. It not too long ago lapped the 20.8-kilometer model of the Nürburgring observe in 7: 09.300 and it went across the 20.6-kilometer observe in 7: 04.511. For context, the GT4 RS is 23.6 seconds sooner than the GT4 on the shorter observe, which is a big distinction. Granted, not everybody lives close to the ‘Ring, however this time argues the GT4 RS was designed for severe efficiency.
“This automotive will make historical past,” Preuninger concluded.
Porsche will current the 2022 718 Cayman GT4 RS on the 2021 version of the Los Angeles auto present, which opens its doorways to the press on Wednesday and to most people on November 19. Deliveries will begin in the summertime of 2022, and pricing begins at $143,050 together with a compulsory $1,350 vacation spot cost. That is about $40,000 greater than the common GT4. The listing of choices will embody the Weissach package deal, proven in these pictures, which provides a number of carbon fiber elements (door mirror caps, consumption surrounds and the rear wing) and exposes the carbon fiber hood reasonably than portray it. Weissach can been enhanced additional with magnesium wheels, together with these painted the blue colour you see right here.
