CHRISTOPHORUS | 359 TO THE POINT TO THE POINT CHRISTOPHORUS | 359 “It’s the mid-engine design 359 TO THE POINT: that makes the Cayman what it is and ensures a special MID-ENGINE DESIGN driving experience.” Mid-engine sports cars have a long tradition at Porsche. The new Cayman interprets this technical concept to the benefi t of increased driving pleasure. Two experts compare notes on theory and practice: Hans-Jürgen Wöhler, director of the Boxster and Cayman series, talks with Porsche test driver Timo Kluck about dynamism, balance, and lightness.
