Now that the new track-focused Porsche 911 GT3 has arrived, the wait for the more hardcore RS variant has started. This isn't the only new RS model Porsche is cooking up, however. For the first time ever, the Porsche 718 Cayman GT4 is getting the hardcore RS treatment, and it promises to be something special. Once again, Porsche has been caught testing a prototype of the new Cayman GT4 RS, this time with less camouflage covering its aggressive, aerodynamically optimized body.

We now get a clear view of the air intake replacing the rear side window feeding cool air into the more potent 4.0-liter flat-six. Curiously, Porsche is still testing the Cayman GT4 RS with different configurations, suggesting there could be a hardcore Weissach Package available for even more badassery.

One prototype is fitted with center lock wheels and a larger front splitter. Additional camouflage is also covering the front fenders, which could be hiding air outlets similar to the ones on the GT3 RS. Other RS design cues include a vented hood and a ginormous swan-neck rear wing.

Like the regular 718 Cayman GT4, Porsche's new hardcore track toy will be powered by a 4.0-liter flat-six. This unit generates 414 horsepower and 309 lb-ft of torque in the regular GT4, but the RS version is expected to have around 450 hp to play with.

Rumors have claimed Porsche is cranking the GT4 RS up to 500 hp putting it on par with the GT3, but this seems unlikely as it would cannibalize GT3 sales. Like the GT3 RS, the Cayman GT4 RS will likely only be offered with a quick-shifting PDK transmission, whereas the regular Cayman GT4 is available with a six-speed manual.

It will also be lighter and more agile than its standard sibling, so it should be capable of setting some blisteringly fast lap times when pushed to the limit. The Cayman GT4 RS is expected to debut this summer, and from what we've seen so far it will be worth the wait.
