Naturally-aspirated flat-six for new Cayman GT4

Porsche will stick with naturally aspirated power and throttle response for its Cayman GT4, despite pressure to move to a turbocharged engine.

While the mainstream 718 versions of the Boxster and Cayman all use turbocharged, four-cylinder engines, sources at Porsche insist the GT4 will borrow the 911 GT3’s flat six.

That means it will use a 4.0-litre, horizontally opposed engine, slightly detuned from its flagship coupe, to give the second-generation Cayman GT4 as much of a power rise as Porsche wants it to have. – BD Motor News
