The six-cylinder boxer engines fitted in the new top models are based on the 3.4-litre engines from the Boxster S and Cayman S respectively. Thanks to optimised fine tuning they now deliver an additional 15 hp (11 kW). This means that the Boxster GTS now has an output of 330 hp (243 kW), whilst the Cayman GTS delivers 340 hp (250 kW). The Boxster GTS sprints from 0-100 km/h in 4.7 seconds, whilst the Cayman GTS is even a tenth of a second faster. The Boxster GTS and Cayman GTS combine top driving dynamics with the typical Porsche spread with undiminished ride comfort and exclusive features.
