Seyth Miersma reviews the Porsche 911 GTS for digital car magazine, Winding Road. Powered by the same 3.8 L flat-six engine as the Carrera S, but fitted with the usually optional Power Kit as standard, the wide-bodied GTS develops 300 kW (408 hp) and of 420 Nm (310 lb-ft) torque. That’s enough to provide a 0-100 km/h (62 mph) time of 4.2 seconds and a 306 km/h (190 mph) top speed.
