The 2013 Porsche Cayman 981 was recently spied on public roads, during rush hour. The prototype caught on camera wears very little camouflage. This means that the 2013 Cayman is getting closer to its premiere. Porsche already revealed the Cayman's open-top sibling last week, which leaves room for some speculation. The 2013 Cayman will probably get the same engines as the new 2013 Porsche Boxster. This means that the 2013 Porsche Cayman will have a 265 hp 2.7-liter flat 6-cylinder engine, while the 2013 Cayman S will get a 315 hp 3.4-litre flat-six powertrain.
