As our recent spy photos proved, aside from a Cayman GT4, Porsche is also working on a GT4 version of the facelifted Boxster.

The blue prototype we caught unguarded earlier this month, had the same exact upgrades and updates as the closed-top Cayman GT4 testers, from the more aggressive aerodynamic components and vented hood lip, to the beefy wheels and brakes.

If you don’t want to put your imagination to work, the team over at Topspeed have crafted a realistic rendering of the sports model based on the Boxster GT4 spy shots.

The question on what engine will power the GT4 models remains open, as there are conflicting reports, with some sources pointing to a new turbocharged flat-four or six, and others to a larger displacement version of the Cayman GTS’ atmospheric flat-six with 3.6-liters delivering anywhere between 360hp to 400hp.

Thanks to Topspeed for sharing the rendering!
