Looks like the engineers at Porsche->ke1 are testing out the latest version of the mighty 911. This is likely the upcoming 2015 Porsche 911 GT3 RS. The test mule is sporting those signature 911 Turbo air intakes on the side fenders, the same wheels we saw on the 911 GTS RS scale model that leaked last month, and that massive rear wing.

Rumors suggest the 911 GT3 RS will have a turbocharged version of the 3.8-liter flat six-cylinder likely making just over 500 horsepower. A PDK transmission will also be a part of the GT3 RS, giving drivers lightning-fast shifts. With a 0-to-60-mph time estimated around three seconds and a top speed just under 200 mph, the RS version of the 911 GT3 will definitely be a superior performer.

This particular test mule is fitted with an internal roll cage and several layers of body cladding, the first designed to protect the occupants and the latter designed to preserve the new Porsche’s true identity. There’s no covering up that beautiful exhaust note, however. It bellows from the tailpipes with a fierceness as the PDK slams into the next gear.

Video->ke278 evidence like this makes us look forward to hearing official words from Porsche on its upcoming model. Be sure to check out the short video above.
