The 2017-2025 Porsche 718 Cayman

Overview

The 718 Cayman represents the entry point to Porsche's mid-engine sports car lineup, introduced in its current form in 2017. This generation retained the lightweight, aluminum-intensive construction that has defined the model since its 2005 inception, while completely revising the powertrain strategy with turbocharged four-cylinder engines. The base model employs a 2.5-liter turbocharged unit producing 350 horsepower, delivering direct competition to established platforms in the €50,000-€60,000 segment. With its 1,300-kilogram curb weight and mid-mounted engine placement, the Cayman prioritizes mechanical balance and handling precision over outright acceleration figures.

The 718 designation represents a marketing reversion to early-1960s nomenclature, acknowledging Porsche's racing heritage while signaling the departure from flat-six engines that characterized prior generations. The turbocharged four-cylinder architecture provides meaningful advantages in fuel consumption and emissions compliance without sacrificing the responsive mid-range characteristics essential to the model's appeal. Buyers encountered mixed reception to this engine transition, with some appreciating the efficiency gains and others lamenting the loss of the naturally aspirated six-cylinder's higher-revving character.

Engineering & Development

Porsche's engineering team retained the 718 Cayman's established chassis architecture while implementing comprehensive refinements to suspension geometry, damper calibration, and steering response. The 2.5-liter turbocharged four-cylinder engine features a single turbocharger mounted low in the engine bay to maintain a favorable center of gravity and preserve the model's mid-engine dynamics. This powerplant delivers 350 horsepower at 6,000 rpm and 420 newton-meters of torque between 1,900 and 5,000 rpm, enabling a 4.4-second sprint to 100 kilometers per hour from a standstill.

The transmission options include a six-speed manual gearbox or a seven-speed dual-clutch automated manual, with the latter offering launch control integration and downshift blipping on overrun. The double-wishbone suspension employs coil springs over dampers with adjustable anti-roll bars, maintaining the configuration that has proven effective across Porsche's lightweight sports car programs. Braking duty falls to iron discs with six-piston calipers at the front and four-piston units at the rear, providing excellent pedal feel and modulation characteristics typical of the marque's brake engineering philosophy.

Market Variants

The 718 Cayman and 718 Cayman S represent the breadth of Porsche's turbocharged four-cylinder offerings, with the S model delivering 350 horsepower from the same displacement through enhanced turbocharger sizing and fuel injection mapping. Both variants maintain identical platform architecture and suspension geometry, differentiating primarily through powertrain output and minor cosmetic styling cues. The manual transmission option is available on both models, appealing to enthusiasts prioritizing tactile engagement over convenience automation.

Interior appointments feature a centrally mounted infotainment display measuring 7.0 inches on the base model, with optional larger units available. The cabin materials employ soft-touch polymers and textile trim standard, with optional leather and Alcantara upgrades available. Cargo capacity measures 260 liters behind the engine, adequate for weekend touring while maintaining the low center of gravity critical to handling balance.

Significance

The 2017-2025 generation establishes the 718 Cayman as a cornerstone of Porsche's volume production strategy, offering genuine sports car dynamics at a price point accessible to a broader demographic than the marque traditionally commanded. The turbocharged four-cylinder adoption reflects broader industry trends toward downsizing and electrification, positioning the model as a bridge between traditional combustion engineering and future drivetrain technologies. The mechanical mid-engine layout ensures that the fundamental handling characteristics remain relevant regardless of powertrain evolution, preserving the philosophical foundation that distinguishes the Cayman from front-engine competitors.
