Announced on 2 July 2025 as part of a trio of new all-wheel-drive 911 variants for the 2026 model year (alongside the Carrera 4S Coupé and Cabriolet), the 911 Targa 4S is offered exclusively with all-wheel drive — as the Targa body style has been since 2006. It adopts the upgraded drive system of the Carrera S: a 3.0-liter twin-turbo flat-six boxer producing 353 kW (480 PS / 473 hp), 30 PS more than its predecessor, thanks in part to an optimized intercooler system carried over from the 911 Turbo. An eight-speed PDK dual-clutch transmission sends power to all four wheels via Porsche Traction Management. The Targa's fully automatic roof folds the glass rear window back and stows the roof segment in a 19-second choreographed sequence, preserving the wide roll bar that has defined the body style since 1965. The Targa carries the GTS braking system (408 mm front / 380 mm rear discs), standard rear-wheel steering and rear seats, and is heavier than the equivalent coupé.
