Introduced for the 2025 model year, the all-wheel-drive 911 Targa 4 GTS combines the brand's distinctive Targa roof — with its wraparound rear glass and signature roll bar — with Porsche's T-Hybrid performance-hybrid system. A 3.6-liter flat-six with a single electrically assisted exhaust turbocharger (eTurbo) works with a 54-PS electric motor integrated into the eight-speed PDK and a compact 1.9-kWh, 400-volt battery for a combined system output of 532 hp and 449 lb-ft of torque. As the heaviest 911 GTS body style, the Targa 4 GTS is the only GTS variant that does not run the 10 mm-lower PASM Sport ride height; Porsche quotes a 0-60 mph time of 3.0 seconds and a 194-mph top track speed.
