Porsche has unveiled the 718 Cayman GT4 RS, the new flagship of the 718 family.
Armed with lightweight construction, an agile chassis setup, sophisticated aerodynamics and a unique soundtrack, Porsche says that it is an uncompromising, all-round driver’s car.
Starting the performance ante for the GT4 RS is a high-revving mid-mounted engine from the 911 GT3 Cup racing car.
In this application, a 9000rpm top engine speed produces 493bhp. Peak torque is 450Nm.
This naturally aspirated flat-6 is paired to a 7-speed dual-clutch gearbox. And with only 1415kg to push, the 718 Cayman GT4 RS sprints from a standstill to 100km/h in just 3.4 seconds. Top speed is 315km/h.
But this track-ready sports coupe isn’t just about numbers.
Porsche has also graced the 718 GT4 RS with new air intakes positioned just behind the driver and passenger windows. These will not only improve engine air-flow, but are sure to send intake noises right into to the occupants’ ears.
The characteristic air intakes in front of the rear wheels have also been retained for engine cooling.
Also contributing to the performance of the 718 Cayman GT4 RS is a whole suite of weight saving measures.
These include the use of a carbon fibre-reinforced plastic bonnet and front wings, and a rear windscreen made from lightweight glass.
Inside, the door panels sport textile opening loops, the carpets are special lightweight items, and the insulation material has been reduced in a bid to drop the car’s overall weight.
Complementing that weight loss is an extensive aerodynamics package for the 718 Cayman GT4 RS.
The car gets a fixed rear wing which sports a swan-neck attachment and aluminium wing supports. This combines with a 30mm lower ride height than the 718 Cayman to deliver even better aerodynamic performance.
Optimised underbody panelling and a connected rear diffuser, alongside a multi-adjustable front diffuser and a new front spoiler lip, allow the 718 Cayman GT4 RS to produce up to 25% more downforce than the 718 Cayman GT4.
Rounding off the performance enhancements is a new RS-specific shock absorber set-up, as well as modified spring and anti-roll bar rates.
If you’re looking for your 718 Cayman with a bit more visual aggression, there’s also an optional Weissach package to consider.
The package will finish the front luggage-compartment lid, process air intakes, cooling air intakes, airbox cover, exterior mirror upper trims and rear wing in a carbon-weave finish.
Meanwhile, the upper section of the dashboard gets upholstered in Race-Tex material, while 20-inch forged magnesium wheels can be ordered at additional cost instead of the 20-inch forged aluminium wheels.
