The next-generation Porsche Cayman will showcase all-new panels, even though they appear to be extremely similar to the existing model's. Like the Porsche 911, Porsche's idea of evolution includes subtle revisions without upsetting the original characteristics of the car.
With these slight exterior revisions comes all-new dimensions, inside and out. That means the new Cayman will be larger than the existing model. It will feature a longer wheelbase providing additional interior comfort with more legroom and headroom.
As for the engine packages, the new Cayman is expected to receive only minor revisions to the current 2.9-litre and 3.4-litre flat sixes. These revisions are likely to bring hikes in power, by around 10kW, but more importantly, a reduction in fuel consumption. Fuel economy will be improved thanks to the introduction of stop/start technology on the next model.
Rumours have been circulating that the next-gen Cayman will also come with an optional turbocharged four-cylinder powerplant which could be shared with the next Boxtster. We'll have to wait for more details to confirm this, however.
The 2013 Porsche Cayman is expected to debut sometime in 2012, alongside the new Porsche Boxster.
