A fully camouflaged prototype of a beefier Mercedes-AMG GT version has been caught on camera stretching out on the 'Ring.

Essentially a road-going version of the track-only Mercedes-AMG GT3, the new model will slot underneath the unreleased range-topping Black Series and as you can see it will boast a more aerodynamic body with winglets on the front fenders along with a huge rear wing.

Don't expect to see the racecar's normally aspirated 6.3-liter V8 engine as the road-legal equivalent will likely use an uprated version of the twin-turbo V8 4.0-liter taken from the regular model . While the AMG GT S packs a 510 PS (375 kW) punch, the higher performance version is likely getting around 550 PS (404 kW) wrapped around in a lighter body compared to the AMG GT S which weighs 1,645 kg (3,626 lbs).

These changes should shave off 0.2s from the 0-62 mph (0-100 km/h) sprint time so the journey should take just 3.6 seconds. The more aerodynamic body likely tweaked for quicker accelerations could bring a slight decrease in top speed from electronically-capped 193 mph (310 km/h) in the AMG GT S.

An official reveal of the car should occur sometime in 2016 and obviously it won't be called GT3 since Porsche would have a problem with that.
