The Porsche Carrera Targa 4 and 4S have a twin-turbo flat-6 engine pushing out either 370 hp or 420hp to all four wheels through either a 7-speed manual or dual-clutch transmission. Both are very quick but opting for the 4S unlocks further available performance upgrades such as the Powerkit and rear-axle-steering. Other notable options include 18-way adaptive power seats and a Burmester audio system. A range of interior and exterior finishes allow for additional customization. The ride, handling and daily usability are still class-leading too and the folding roof mechanism offers the best of both worlds.
