Its been rendered and rumored, but here are the first spy photos the 2013 Mercedes SLS AMG Black Series.
Caught at a testing center in Germany, the prototype has a wide body kit with a modified front fascia, revised side skirts and extended fenders. We can also see high-performance brakes and larger rear wheels which hint at some changes to the rear axle.
Under the hood, rumors suggest the 6.3-liter (6,208cc) V8 engine could deliver 600 hp (447 kW / 608 PS) and 677 Nm (499 lb-ft) of torque. This will likely enable the car to accelerate from 0-100 km/h in 3.5 seconds and hit a top speed in excess of 322 km/h (200 mph).
