For those enamored with the Porsche badge and a penchant for spirited driving, the Porsche 718 Cayman GT4 RS stands as the epitome of high-performance engineering.

With a race-engineered body and a robust 500-horsepower flat-6 motor, this range-topping variant takes the Cayman experience to new heights.

In this comprehensive road test report, we explore the GT4 RS’s design, powertrain, performance, features, and functionality to decipher its place in the market.

Design & Aesthetics:

The Cayman, inherently shadowed by the iconic 911, showcases a design reminiscent of its legendary sibling.

While it may not match the sheer beauty of the flagship, its size, measuring 4,456 mm in length, 1,822 mm in width, and 1,267 mm in height, positions it as an ideal sports car.

The GT4 RS, however, elevates the Cayman’s aesthetic with NACA air intakes, louvers in the CFRP wings, and a swan neck rear spoiler for increased down force.

The low-slung interior, though a nod to a 2016 design, exudes richness with alcantara-wrapped elements and a unique ambiance created by the combination of black leather and deep-sea Race-Tex seat upholstery.

The 718 Cayman GT4 RS is a form that meticulously follows function.

Powertrain & Performance:

The heart of the GT4 RS is its naturally aspirated 4.0-litre 6-cylinder boxer engine, inherited from the GT3, delivering a thunderous 500 PS at 8,400rpm and 450 Nm at 6,750 rpm.

The absence of a start button adds a classic touch as the engine roars to life upon turning the key.

With a 7-speed DSG transmission, the GT4 RS exhibits brutal acceleration, reaching 100 km/h from a standstill in a mere 3.4 seconds.

The quarter-mile is conquered in 11.3 seconds, while the top speed touches an impressive 315 km/h.

The precision of the chassis, enhanced by uprated springs and dampers, allows for surgical control through sharp corners and sweeping turns.

The braking system, featuring 6-piston calipers and massive discs, ensures authoritative stops. Despite its exhilarating performance, the GT4 RS maintains a compliant ride quality.

Features & Functionality:

In terms of practicality, the GT4 RS offers two trunks, with 125 litres upfront and 134 litres behind the engine.

The interior, adorned with a functional yet slightly dated infotainment system, includes 2 retractable cupholders and a 10-speaker 505-Watt Bose audio system.

Safety features encompass cruise control, rear parking sensors, a reversing camera, and a tire pressure monitoring system.

The dual-zone air conditioning system ensures comfort, while an optional front axle lift system prevents undercarriage scraping.

However, cargo space is limited, and the location of the fire extinguisher may impede passenger legroom.


The Porsche 718 Cayman GT4 RS emerges as the apex of the Cayman lineup, combining racy aesthetics, raw performance, exclusivity, and impeccable build quality

While its unconventional beauty may not appeal to everyone, its track-inspired design, race-derived engine, and exceptional chassis dynamics establish it as a definitive race car for the road.
