As we mentioned before, the 3.4-liter Boxer engine in the Cayman S is quite different than the one powering the non-facelift version. It sports the same displacement, but a totally new direct injection system was fitted to it, making it both more powerful and more frugal, which of course is a bit antithetic.
Just like on all the engines powering the 911 range, the natural aspirated flat-six in the Cayman is also using the Porsche VarioCam Plus system. In plain "engineering English", this system combines variable valve timing with two-stage lift on the inlet side. In other words, the smooth rise in rpm when accelerating and the great torque output at low and medium ranges are happening thanks to this system.
Apart from following the Boxer principle, meaning it has a very low center of gravity, the engine is also using a dry-sump lubrication system, meaning it sits even lower than a regular engine. Together with the lower center of gravity, the use of dry-sump also improves lubrication during hard cornering and/or braking. All in all, the 3.4-liter Boxer is a very impressive piece of technology, offering no less than 320 horsepower at a stratospheric 7200 rpm and an equally impressive 370 Nm (272.9 lb ft) of torque at 4750 rpm. Coming from a natural aspirated engine of this capacity, this is pretty impressive.
An even more impressive piece of technology is the PDK double-clutch transmission. We're driven cars with double-clutch sequential gearboxes before, but none of them behaved as exemplary as the one from the Cayman S. Instantaneous shifts, seven forward speeds and a manual mode to keep every Formula One fan happy. This is simply the best gearbox we've ever experienced when it comes to sportiness, be it in manual or automatic mode.Continue reading
