Porsche unveiled a flagship model in the 718 family – the new 718 Cayman GT4 RS that shares a naturally aspirated engine with the 911 GT3. The flat-six engine revs up to 9,000 rpm. Power increases by 79 hp compared to the 718 Cayman GT4 to a total of 493 hp, resulting in a weight-to-power ratio of 6.55 lbs. per hp. Maximum torque increases from 317 lb.-ft. to 331 lb.-ft. The 718 Cayman GT4 RS accelerates from 0 to 60 mph in 3.2 seconds – half a second faster than the 414 hp 718 Cayman GT4 with PDK. The top track speed is 196 mph, which the GT4 RS reaches in seventh gear.
The significantly enhanced performance of the car is accompanied by many changes of appearance. Among the many design changes applied to the 718 Cayman GT4 RS are the air intakes behind the side windows on the driver and passenger side where other 718 Cayman models would usually have a small window. The new RS-specific air intakes enhance the flow of intake air, which can be clearly heard due to the proximity to the driver’s and passenger’s ears. Side intakes in the rear quarter panels are still present but revised to meet the greater cooling demands of the new engine.
The new 718 Cayman GT4 RS will be offered exclusively with the seven-speed dual-clutch transmission (PDK) that allows the gears to be changed instantly. Using shift paddles mounted on the steering wheel, drivers can change gears manually as they choose without taking their hands off the wheel. They can also change gears manually using the newly designed shift lever in the center console.
The new car is constructed using lightweight materials. The front fenders and hood are formed out of carbon fiber reinforced plastic (CFRP), while the rear window is made of lightweight glass. Lightweight door panels with fabric door opening loops and storage nets round off the focus on lowering weight.
The new, fixed rear wing with swan neck mounts and aluminum supports represents a difference from other 718 models, including the GT4. Combined with a ride height that is 30 millimeters lower than a standard Cayman, front-wheel well ventilation, an aerodynamically optimized underbody with a rear diffusor, an adjustable front diffusor, and a new front spoiler lip with flow-around side-blades, the GT4 RS generates up to 25 percent more downforce in the racetrack-only Performance mode than the 718 Cayman GT4. The enhanced suspension also contribute to an even higher level of performance. 20-inch forged aluminum wheels with center locks are used for the first time on a 718 Cayman model.
To celebrate this impressive car, Porsche Design has created a Porsche Design Chronograph 718 Cayman GT4 RS, which will be offered exclusively to buyers of the vehicle.
The new car is priced at $141,700, not including a $1,350 delivery, processing, and handling fee. It is expected to reach U.S. dealers in the course of summer 2022. The racing version 718 Cayman GT4 RS Clubsport will be taking part in many national and international racing series next year.
