Porsche 718 Cayman (982) GT4 Clubsport 3.8 (425 Hp) PDK

The Porsche 718 Cayman (982) GT4 Clubsport 3.8 (425 Hp) PDK represents the pinnacle of Porsche’s mid-engine sports car philosophy, specifically engineered for the demanding environment of competitive motorsport and dedicated track use. Launched in 2019, this generation of the Cayman, designated 982, took the already formidable GT4 platform and elevated it to Clubsport specification, making it an accessible yet highly potent machine for privateer racers and track day enthusiasts worldwide. Unlike its road-legal counterpart, the Clubsport variant is a purpose-built racing car, stripped of non-essential amenities and outfitted with crucial performance and safety enhancements. It embodies Porsche’s long-standing tradition of translating racing technology into vehicles that deliver unparalleled driver engagement and performance, positioning itself as a serious contender in various GT4 racing series and as an ultimate track weapon for discerning drivers.

Engine and Performance: The Heart of the Porsche 718 Cayman (982) GT4 Clubsport 3.8 (425 Hp) PDK

At the core of the Porsche 718 Cayman (982) GT4 Clubsport 3.8 (425 Hp) PDK lies a magnificent 3.8-liter naturally aspirated flat-six engine, designated by the code DKDA. This powertrain is a testament to Porsche’s commitment to high-revving, responsive engines, delivering a robust 425 horsepower at a screaming 7500 rpm. The engine’s naturally aspirated design, a rarity in an era increasingly dominated by turbocharging, provides a linear and predictable power delivery, allowing drivers to precisely meter throttle input – a critical advantage on the race track. Torque peaks at 313.46 lb.-ft. (425 Nm) at 6600 rpm, ensuring strong acceleration out of corners and impressive mid-range pull. With a maximum engine speed of 7800 rpm, this powerplant is designed to be pushed hard, rewarding the driver with an exhilarating auditory experience and relentless thrust.

The engine’s technical specifications highlight its race-bred pedigree. With a bore of 102 mm and a stroke of 77.5 mm, the flat-six configuration boasts a compression ratio of 12.5:1, optimizing combustion efficiency for high performance. Each of its six cylinders features four valves, contributing to excellent volumetric efficiency and the impressive 111.8 horsepower per liter output. Power is sent to the rear wheels via a sophisticated 6-speed automatic PDK (Porsche Doppelkupplung) transmission. This dual-clutch gearbox is renowned for its lightning-fast and seamless gear changes, allowing for uninterrupted power delivery and maximizing acceleration, crucial for shaving precious tenths off lap times. The drivetrain architecture is straightforward: an internal combustion engine driving the rear wheels, a classic setup for a pure sports car that offers engaging handling and predictable dynamics.

The performance metrics further underscore the vehicle’s track focus. With a kerb weight of 2910.1 lbs (1320 kg), the GT4 Clubsport achieves an impressive weight-to-power ratio of 3.1 kg/Hp, equating to 322 Hp per tonne. Similarly, its weight-to-torque ratio stands at 3.1 kg/Nm, or 322 Nm per tonne. These figures illustrate the meticulous engineering that went into minimizing mass while maximizing output, resulting in a car that feels incredibly agile and responsive. The mid-engine, longitudinal layout of the engine contributes to an optimal weight distribution, enhancing the car’s balance and cornering capabilities, making it a formidable tool for competitive driving.

Design and Features: Form Follows Function in the GT4 Clubsport

The design of the Porsche 718 Cayman (982) GT4 Clubsport is a masterclass in functional aesthetics, where every element serves a purpose in enhancing performance and safety. As a two-door coupe, its silhouette is instantly recognizable as a Porsche, yet its aggressive stance and aerodynamic enhancements hint at its track-only intentions. The most striking feature is its single-seat configuration, a clear indication of its racing pedigree, prioritizing weight reduction and driver focus over passenger comfort. This minimalist approach is central to the Clubsport ethos, shedding any unnecessary weight that doesn’t contribute to outright performance.

Dimensionally, the GT4 Clubsport measures 175.43 inches (4456 mm) in length, 70 inches (1778 mm) in width, and 48.74 inches (1238 mm) in height, with a wheelbase of 96.69 inches (2456 mm). These compact dimensions, combined with its lightweight construction, contribute to its exceptional agility and responsiveness on the circuit. The car features an independent McPherson-type suspension at both the front and rear. This robust and proven setup provides precise wheel control, allowing for optimal tire contact patch and delivering consistent handling characteristics under extreme loads. The suspension is typically tuned for track use, offering stiffer springs and dampers for reduced body roll and enhanced cornering stability.

Braking performance is paramount in a track car, and the GT4 Clubsport delivers with ventilated disc brakes on both the front and rear axles. These high-performance brakes are designed to withstand the intense heat generated during repeated heavy braking, providing consistent and powerful stopping force. An Anti-lock Braking System (ABS) is standard, offering crucial assistance in maintaining control during emergency braking or under slippery conditions. Steering is managed by an electric rack and pinion system, offering precise feedback to the driver while reducing parasitic losses associated with hydraulic systems. The inclusion of a particulate filter in the engine system also reflects modern environmental considerations, even in a dedicated racing machine.

Beyond these core mechanical features, the “Clubsport” designation implies a comprehensive suite of racing-specific equipment. While not explicitly detailed in the specifications, such vehicles typically include a welded-in roll cage, racing seats with multi-point harnesses, a fire suppression system, and a quick-release steering wheel, all designed to meet international motorsport safety standards. The aggressive aerodynamic package, including a prominent rear wing and front splitter, is engineered to generate significant downforce, enhancing grip and stability at high speeds. Every aspect of the Porsche 718 Cayman (982) GT4 Clubsport 3.8 (425 Hp) PDK is meticulously crafted to deliver an uncompromised, exhilarating, and safe racing experience.
