Porsche’s new Cayman S is essentially a Boxster with a roof and more power.

On sale in the UK from November, the Cayman S uses Porsche’s variable intake camshaft control system to boost power of its 3.4-litre flat-six to 295bhp, giving a top speed of 171mph and 0-62mph in 5.4 seconds. The six-speed manual version will cost £43,930 on-the-road.
