It is of course detuned to protect the 911 Carrera S image and has 'only' 385 horsepower instead of the full 400. Porsche is the master of creating artificial hierarchy and reinforces this artificial positioning by horsepower numbers. They have finally, and significantly, allowed a Cayman to outpower the 911 Carrera though.
So what did Porsche do here other than give the Cayman the Carrera S engine? They gave the car revised aerodynamics as well as pieces from the 991 GT3. The brakes and suspension are stated by Porsche to consist 'almost entirely' of components from the GT3 model.
What is notably absent from the 991 GT3 is the PDK dual clutch transmission. The 991 GT3 is offered as PDK only whereas the Cayman GT4 is offered as manual only. Interesting, isn't it? With the GT3 it is understandable as the car is lower volume and the PDK offers superior performance to the manual transmission.
PorscheBoost believes Porsche is not offering the PDK option as the Cayman GT4 would easily outpace the Carrera S which is offered with PDK as well as the manual transmission. It costs Porsche nothing to add the PDK option as the motor is the same as the Carrera S motor. This is a political decision as they easily have the ability to offer both as they already produce and offer both in the Carrera S.
The Cayman S and Boxster S of course also use this same transmission with their 3.4 liter flat-6 units borrowed from the 911 Carrera.
If you want a manual Porsche track car it looks like the Cayman GT4 is the choice. It also helps that it is cheaper than the GT3 at $84,600.00.
A New Member of Porsche's GT Family
The benchmark in its class: the Porsche Cayman GT4
Atlanta, Feb. 3, 2015 - Porsche's GT family is proud to announce the addition of an exciting new member: the Cayman GT4. This is the first Porsche GT sports car based on the Cayman and features components of the 911 GT3. Clocking a lap time of 7 minutes and 40 seconds on the North Loop of the Nürburgring, the Cayman GT4 earns the same lap time as the 2011 911 GT3 and positions itself as the new benchmark atop its market segment. The Cayman GT4 clearly demonstrates Porsche's dedication and passion to continue to promote truly industry-leading two-door sports cars in the future – sports cars that are developed at the Motorsport department in Weissach.
The engine, chassis, brakes, and aerodynamic design of the Cayman GT4 are configured for maximum driving dynamics while retaining the versatility and everyday utility that are typical of the two-seater Porsche coupe. Powered by a 385 hp 3.8-liter flat-six engine derived from the 911 Carrera S engine, the Cayman GT4 transmits its power solely through a six-speed manual transmission with dynamic gearbox mounts. Zero to 60 mph is accomplished in 4.2 seconds; its top track speed is 183 mph. The chassis – which features a 30 mm lower ride height and a generously sized brake system – consists almost entirely of components from the 911 GT3.
Ready for the race track: The first Porsche Cayman with added downforce at both axles
The exterior of the Cayman GT4 highlights it as a member of the Porsche GT family and provides a clear distinction to related mid-engine coupes. Three pronounced inlet openings at the front and a large fixed rear wing are part of an aerodynamic package which is systematically designed for downforce. Upon request, the performance capabilities of Cayman GT4 can be taken even further. Available options include the Porsche Ceramic Composite Brake (PCCB) system, full bucket seats made of carbon fiber composite, and a custom Sport Chrono Package featuring a Track Precision app.
The interior of the Cayman GT4 focuses on maximizing the experience of unfiltered driving enjoyment for both driver and passenger. Standard sport seats, which are upholstered in a combination of leather and Alcantara®, offer excellent lateral support. The new Cayman GT4 sport steering wheel guarantees ideal control and direct steering feedback due to its compact dimensions.
Technical aspects of this new GT sports car are based on the 911 GT3. As a mid-engine sports car and a prime example of driving dynamics in its class, it follows the conceptual tradition of such cars as the 904 GTS, 911 GT1, Carrera GT and 918 Spyder.
GT sports cars engineered by Porsche embody the most passionate connection possible between everyday driving and Porsche's competition heritage and highlight the sporty core of the brand: Intelligent Performance.
The Porsche Cayman GT4 celebrates its world premiere in early March at the Geneva International Motor Show. This vehicle will arrive at U.S. dealers in July 2015. The starting MSRP for the Cayman GT4 is $84,600. MSRP does not include a destination charge of $995.
