That is the advantage if you have a modular construction system. In principle, all rear engines fit also in the middle of the Cayman or Boxster. But the prices are the problem at Porsche. The Cayman is basically much cheaper than the 911 and as GT4 must not get too close to the Carrera S, even if it has its engine.

It lost 11 kW (15 HP) power and 20 Nm of torque, in this performance class certainly bearable. Not only by this means it is 9 km/h slower. The 911 might also have a slightly more favourable wind shape, despite prolonged front of the GT4. Each around 20,000 euros, this Cayman separate from both the Carrera S in the price upwards as the Cayman S down.

It has the ceramic brakes of the Carrera S, but 'only' six speeds and is not available with dual clutch transmission PDK. Although this would decrease just its 2 emissions by ten percent. The performance and torque difference to the Cayman S is slightly greater. However, the is optional available with Porsche dual-clutch transmission (PDK). However, if you look at the video below, prices are initially forgotten.

Longer and lower than the normal Cayman, rather more intended as a racing car. Despite only two way adjustable full bucket seat, they were not stingy with Alcantara leather. Nevertheless, the racing upgrade is available e.g. with roll bar. Electronically controlled damping and transverse differential lock are standard. Therefore the GT 4 offers much of what is otherwise bought in addition. 02/15
