The Boxster and Boxster S have debuted together, and both are powered by flat-six engines with direct fuel injection. Efficiency is further enhanced by electrical system recuperation, thermal management and start/stop function. What about performance we hear you cry? Well, the base model now delivers 265hp from a 2.7-liter flat six nestled behind the seats, ten horses more than its larger displacement predecessor; the Boxster S delivers 5hp more than before with 315hp managed by its 3.4-liter six. Both are mated to a manual 6-speed transmission with an optional 7-speed PDK that offers the best fuel consumption and acceleration performance.
