A Porsche 718 Boxster Spyder Is On The Way With The GT3's 4.0 Flat-Six

The incoming Cayman GT4 will be joined by a Boxster Spyder, both powered by the same 911 GT3-sourced N/A six

We’ve been fairly sure for a while that Porsche is cooking up a 718 Cayman ‘GT4’ with a naturally-aspirated flat-six, but now we know it’ll have a cousin: a 718 Boxster Spyder.

Autocar reports that Stuttgart is developing a successor to the ‘981’ Spyder (pictured above and below), which will shirk the 2.5-litre, turbocharged flat-four used in the 718 Boxster S and GTS in favour of an N/A six. It’ll trump the 3.8-litre 911 Carrera S unit used in the previous Spyder, too: like the next Cayman GT4, it’ll use a detuned version of the 911 GT3’s incredible 4.0-litre flat-six, hooked up to a manual gearbox.

As far as power goes, that’s open to speculation. In the GT3, the motorsport-derived six-banger is good for 493bhp, while the old Boxster Spyder made a more modest 370bhp. So, the output should be somewhere in between those figures, albeit closer to 370 than 493. Let’s take an educated guess of 420bhp and see how right we end up being.

Along with the shoutier engine, we can also expect overhauled suspension, stickier tyres and various weight saving measures to make this the most potent Boxster ever seen.

The question is, would you have the 718 Boxster Spyder, or the 718 Cayman GT4?
