Not that Porsche was really trying to hide its Cayman GT4 testers, but the firm’s new coupe has been caught without any camouflage while also wearing a production rear wing.

It’s a hotly anticipated model, akin to a junior 911 GT3, with a host of performance and aerodynamic improvements over the regular Cayman coupe.

With the exception of the alloy wheels, the rest of the car seems production ready featuring a different front bumper with bigger air inlets, a protruding splitter and LED daytime lights, a new cooling duct in front of the bonnet, a fixed rear wing, and a rear diffuser with two central pipes.

And it’s not only the visuals, as Porsche will give the GT4 a noticeable power bump over today’s most powerful version of the Cayman, the 335hp (340PS) GTS. The question of whether the GT4 will debut Porsche’s new line of turbocharged engines or if it will stick to a naturally aspirated flat-six with an output of around 360hp to 400hp remains unanswered.

Elsewhere, the Cayman GT4 will gain a lowered and re-tuned suspension, beefed up brakes, and according to some rumors, it could also be lighter than the GTS.

Porsche has also been spied testing a similar version of the Boxster.
