A thinly camouflaged prototype of the Porsche 911 Turbo S has been spied inside and out ahead of this year's official launch.

At a first glance it might look exactly the same as the current model but the exterior does host an array of changes, including different graphics for the headlight & taillight clusters, new LED daytime running lights, revised engine cover and modified door handles. The front and rear bumpers are hiding underneath a body-colored camouflage which indicates these have received some updates as well.

Stepping inside the cabin, the steering wheel seems to be sourced from the 918 Spyder and boasts a toggle switch mounted on the right-hand side. This prototype also appears to boast a larger display for the infotainment system while the buttons underneath have a slightly different layout compared to the outgoing model.

The facelifted 911 range will be unveiled later this year, possibly in September at the Frankfurt Motor Show where Porsche could bring an all-turbo lineup, with the exception of the 911 GT3 and 911 GT3 RS models. The Stuttgart-based company has already hinted at a 911 hybrid but they will probably wait until the next generation scheduled to come out towards the end of the decade.
