2013 Porsche Cayman video review
Its fixed metal roof gives it a stiffer body than the Boxster, while its mid-engined configuration makes the Cayman inherently better balanced than the rear-engined 911.
Compared with the first-generation car, the new Cayman is lower, wider and has a much stiffer structure. It's also up to 30kg lighter, and should use as much as 15% less fuel.
Two six-cylinder petrol engines are available – a 2.7-litre with 271bhp and a 3.4-litre with 320bhp. Both versions send power to the rear wheels through a six-speed manual gearbox, although Porsche's seven-speed twin-clutch PDK semi-auto 'box is available as an option.
Neither car promises to be cheap to run, although Government average economy for the 2.7-litre version is 34.4mpg – a respectable number for this type of car.
The Cayman is priced to undercut its rivals, but Porsche is not miserly with standard equipment, so expect a visit to the options list to get all the kit you need.
