About the 2020 Porsche 718 Cayman

3rd generation (982, 2017-2024), fourth model year; 2020 adds the Cayman T and Cayman GT4 to the U.S. lineup.

Porsche positions the 718 Cayman as the entry point to its two-door sports cars, but not as a stripped-down compromise. The core appeal is a compact mid-engine layout, rear-wheel-drive balance, and a cockpit centered on driver control. Compared with rivals, the Cayman leans more toward precision and feel than raw flash. Even before stepping into the T or GT4, the regular 718 Cayman is sold as a true sports coupe first, with everyday usability as a bonus.

The 2020 range stretches from the balanced 300-hp base Cayman to the quicker 350-hp Cayman S. The Cayman T focuses on sharper road driving with lowered adaptive suspension, a limited-slip differential and a drive-mode package, while the GT4 sits at the top with a naturally aspirated six-cylinder engine, stronger brakes and track-focused aerodynamics.

What changed, by category

Powertrain

The new Cayman GT4 brings a naturally aspirated 4.0-liter flat-six with 414 hp and a six-speed manual transmission. The GTS name changes to Cayman T; the 2020 T uses the base model's 300-hp 2.0-liter turbocharged flat-four.

Styling

The new GT4 has its own aerodynamic bodywork, including a fixed rear wing and rear diffuser.

Structural

The Cayman T has adaptive sport suspension lowered by 20 mm, a mechanical limited-slip differential with torque vectoring, a drive-mode and performance-timer package, and a sport exhaust. The GT4 has suspension lowered by 30 mm, stronger brakes and track-oriented chassis tuning.
