The Porsche 718 Cayman GTS 4.0 (982) represents a return to form for the Cayman line, specifically lauded for reintroducing a naturally aspirated flat-six engine. Launched in September 2020, this variant sits at the top of the 718 Cayman range, offering a more engaging and visceral driving experience compared to the turbocharged four-cylinder models. Positioned in the premium sports car segment, the 718 Cayman GTS 4.0 competes with vehicles like the Chevrolet Corvette, BMW M2, and Audi TT RS, appealing to enthusiasts who prioritize driving dynamics and a connection to the machine.
Porsche 718 Cayman GTS 4.0: A Return to Naturally Aspirated Power
The 982 generation Cayman, introduced in 2016, initially moved away from the traditional flat-six engines favored by Porsche purists, opting for turbocharged four-cylinder units. However, demand for a naturally aspirated option led to the development of the GTS 4.0. This model is not simply a higher-powered version of existing Caymans; it’s a deliberate engineering statement, prioritizing driver engagement and a classic Porsche feel. The “4.0” designation refers to the engine displacement, a key selling point for those seeking a more authentic sports car experience.
Engine & Performance
The heart of the 718 Cayman GTS 4.0 is its 3,995 cc (243.79 cu. in.) naturally aspirated flat-six engine, derived from the 911 Carrera S. This engine produces 400 horsepower at 7,000 rpm and 420 Nm (309.78 lb.-ft.) of torque between 5,000 and 6,500 rpm. The engine’s power-to-liter ratio is an impressive 100.1 hp/l. Power is delivered to the rear wheels via a standard six-speed manual transmission, although a seven-speed PDK dual-clutch transmission is available as an option. The rear-wheel-drive configuration contributes to the car’s balanced handling characteristics. Performance figures are notable, with a 0-60 mph acceleration time of 4.3 seconds, a 0-100 km/h time of 4.5 seconds, and a top speed of 293 km/h (182.06 mph). The engine’s responsiveness and the satisfying sound of the naturally aspirated intake and exhaust are central to the GTS 4.0’s appeal. The weight-to-power ratio is 3.5 kg/Hp, and the weight-to-torque ratio is 3.3 kg/Nm.
Design & Features
The 718 Cayman GTS 4.0 maintains the classic mid-engine, two-seat coupe body style synonymous with the Cayman lineage. Its design emphasizes aerodynamic efficiency and a low center of gravity. Key exterior features include a unique front fascia with larger air intakes, blacked-out trim elements, and a prominent rear diffuser. The car rides on 20-inch alloy wheels, with staggered tire sizes (235/35 ZR20 front, 265/35 ZR20 rear) to maximize grip. Inside, the GTS 4.0 features sport seats upholstered in Alcantara, a GT Sport steering wheel, and various trim accents that distinguish it from other 718 models. Modern features include Porsche Communication Management (PCM) with navigation, Apple CarPlay integration, and available advanced driver-assistance systems. Safety features include ABS, Porsche Stability Management (PSM), and a suite of airbags. The trunk offers 270 liters (9.53 cu. ft.) of storage space, suitable for weekend getaways.
