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 employ a 4.0-litre horizontally opposed engine, slightly detuned from its flagship coupe work, to give the second-generation Cayman GT4 as much of a power rise as Porsche wants it to have.
It’s expected to deliver about 300kW of power, so the rear-drive hard-core Cayman should rip to 100km/h in just over four seconds (the previous generation clocked 4.4).
