Will there be a GT4 RS? Yes, and it will feature the famous high revving, mid-mounted, 9000-rpm capable, 4.0-litres flat-six engine from the GT3 mounted in the middle of one of the most competitive sports car chassis in the world. That’s the brand new Porsche 718 Cayman GT4 RS, and it’s made for driving pleasure.
While the 911 GT3 sets the benchmark for daily driver track weapons, the GT4 RS looks to sit just below its bigger brother in the range but offers a measurable amount of accuracy with the goal being a pure drivers car built for pleasure. This new ‘hardcore’ model breathes new life into the mid-engined chassis in what many speculate to be one of the last normally-aspirated Cayman models as electric vehicles become the focus for customers going forward.
Measurable amounts of accuracy is in everything that an ‘RS’ badged Porsche stands for, but the brand insists driving pleasure is the ultimate end-game for this variant and the GT4 RS looks to push this theory to the forefront.
Power: 500 PS
Torque: 450 Nm
Power-to-weight: 2.83 kg/PS
Acceleration: 3.4 seconds (0 to 100 km/h)
Top-speed: 315 km/h
Starting with the naturally aspirated flat-six engine, fans will recognise its familiar specifications, matching those found in the 911 GT3 series production model. Bearing in mind the Cayman is a mid-mounted model the exhaust notes between GT3 and Cayman are notably different. The Cayman has a focus on induction, with carbon fibre air ducts added in place of the rear quarter glass that presents an exhilarating exhaust noise just 30cm from the occupant’s ear. A large carbon fibre airbox is found on top of the engine with a high-performance cotton-wax filter and the throttle bodies themselves have been flipped horizontally for packaging considerations.
Available exclusively with a PDK gearbox, the RS shifts through 7-gears at class-leading speed. A low ratio gearset has been chosen, meaning owners can explore the full rev-range at a speed safe enough for road use. Shifting is done via the usual flappy paddles on the gearbox, however, a redesigned gear selector on the centre console allows a hybrid manual feel.
Outside of the notable power increase (80 PS), the RS features a number of track-focused chassis additions, including;
- Ball joints between chassis and body for even more precise and direct handling.
- Adjustable, circuit-ready chassis with RS-specific shock absorber set-up.
- Modified spring and anti-roll bar rates.
- Carbon fibre bonnet and front wings.
- Lightweight rear glass, door panels, textile opening loops and nets on the storage compartments.
- 30-millimetre-lower ride height compared to the 718 Cayman.
For those looking to push the boundaries when it comes to options, the famous Weissach package will be available. This package adds even more exposed carbon, including front luggage-compartment lid, process air intakes, cooling air intakes, airbox cover, exterior mirror upper trims and rear wing. This is amongst a slew of titanium on the tailpipes (blue goodness) and roll cage at the rear. The upper section of the dashboard is upholstered in Race-Tex material and a large Porsche logo is integrated into the rear window. Finishing off the ultimate spec is 20-inch forged magnesium wheels that can be ordered at additional cost instead of the 20-inch forged aluminium wheels.
In Australia, the new 718 Cayman GT4 RS will come equipped with automatically dimming mirrors including rain sensors, cruise control, ParkAssist (rear only), reversing camera, Light Design Package and digital radio. Pricing starts at AU$300,800, but expect them to sell out extremely quickly.
