New 911 Targa 4 GTS also gets Porsche’s new T-Hybrid powertrain for more power and better efficiency. Fitted out with a 3.6L flat 6 turbocharged and hybridised engine, the 911 Targa 4 GTS produces 534 hp and 450 lb-ft of torque. It will only be available in all-wheel drive configuration with an eight-speed dual-clutch automatic transmission. The non-GTS version of the Targa will get a more simple 3.0L engine without any electrical assist.
