Porsche is showing off its new Cayman GT4 at the Geneva Motor Show. With that comes a raft of information, new pics and technical specifications.
We’re very happy to bring that all to you now. Because cutaways!
Porsche Cayman GT4â€”The new benchmark in its class
The new entry-level car of the Porsche GT family is the Cayman GT4. The engine and chassis, brakes and aerodynamics of the Cayman GT4 were engineered for maximum driving dynamics, yet this new top model preserves the typical versatility and everyday utility of a two seat Porsche coupe. It is powered by a 3.8-litre flat-six engine with 385 hp (283 kW), which was derived from the 911 Carrera S engine. Its power is handled by a six-speed manual transmission with dynamic transmission mounts. This combination lets the Cayman GT4 accelerate from zero to 100 km/h in 4.4 seconds and attain a top speed of 295 km/h. The car’s combined NEDC fuel consumption is 10.3 l/100 km. The chassis, with its 30 mm lower ride height and generously sized brake system, consists largely of components from the 911 GT3.
Ready for the racetrack: First Porsche Cayman with downforce at both axles
The Cayman GT4 has an independent look. Three distinctive air intakes at the front and a large fixed rear wing are elements of an aerodynamic setup that is uncompromisingly designed for downforce. If desired, the Cayman GT4 can be equipped with an even greater focus on sporty performance. Optional equipment includes the PCCB ceramic brake system, full bucket seats made of carbon fibre reinforced polymer (CFRP), a custom Sport Chrono Package with the unique Track Precision app and a Club Sport Package.
The interior features of the Cayman GT4 let the driver and front passenger experience unfiltered driving pleasure. They sit on sport seats that are upholstered in a combination of leather and Alcantara and offer very good lateral support. The new GT4 sport steering wheel, with its compact dimensions, guarantees precise handling and direct steering feedback.
The technology of the new GT sports car is based on that of the 911 GT3. As a mid-engine sports car and a prime example of driving dynamics in its class, it continues the conceptual tradition of the 911 GT1, the Carrera GT and the 918 Spyder. The new model designation is based on that of the GT4 class, which lets buyers enter into GT car racing at relatively low expense.
