The 2015-2016 Porsche Cayman GT4

Overview

The 718 Cayman introduced the fourth-generation fixed-roof mid-engine coupe platform during 2017-2025, powered by a 2.0-liter turbocharged four-cylinder engine producing 300 horsepower. This model represented Porsche's transition to forced-induction architecture across the Cayman lineup, incorporating turbocharged engines exclusively across all variants. The 718 designation signified the platform's contemporary positioning reflecting the broader industry shift toward smaller-displacement, highly-boosted engines. The turbocharged engine provided responsive power delivery through low-rpm boost characteristics while maintaining fuel efficiency and emissions compliance. The fixed-roof configuration maintained the structural advantages and handling refinement. The 300-horsepower output established the base variant as genuinely capable despite the reduced displacement.

The 718 Cayman philosophy centered on delivering turbocharged mid-engine coupe experiences through responsive boost delivery and contemporary engineering. Porsche's engineering approach emphasized responsive power from forced-induction, improved fuel efficiency, and sophisticated electronic systems. The 2.0-liter displacement with turbocharging provided the power escalation that naturally-aspirated engines struggled to deliver. The 718 represented significant evolutionary advancement toward contemporary performance architecture.

Engineering & Development

The 718 Cayman turbocharged 2.0-liter four-cylinder engine employed water-cooling with aluminum construction. The 300-horsepower output reflected turbocharged forced-induction, with peak torque of 280 lb-ft extending from 1,950 to 4,500 RPM. Variable geometry turbocharger management optimized boost across the operating envelope. Bosch fuel injection with advanced electronic management coordinated power delivery.

The six-speed manual transmission featured direct mechanical linkages. A seven-speed dual-clutch automatic offered responsive operation. Independent double-wishbone suspension provided improved ride and handling. Enhanced brake systems addressed performance requirements. The aluminum frame with selective reinforcement provided structural integrity. The fixed-roof structure provided acoustic benefits and structural integrity.

Market Variants

The 718 Cayman appeared throughout 2017-2025 with the 2.0-liter turbocharged engine. Production extended with approximately 85,000 units manufactured. Geographic distribution favored all major markets. The Cayman attracted entry-level mid-engine sports car customers.

Secondary market demand for 718 examples remains strong among enthusiasts valuing responsive turbocharged performance.
