Mercedes has released 10 minutes of new video footage of the SLS AMG GT3.

Set to enter competition next year, key design features include a new front fascia, a ventilated hood, a carbon fiber front splitter, a massive rear diffuser, and an enormous rear wing. Other goodies include an AMG race braking system, a six-speed racing transmission, roll cage and a steering wheel with buttons for the pit radio, headlight flashers and drink supply.

Under the hood, power is provided by a 6.3-liter V8 engine which is "virtually identical" to the one in the production car. The company declined to provide detailed performance data, but stated the GT3 can accelerate from 0-60 mph in 3.7 seconds (0.2 seconds faster than the standard car) and hit a top speed in excess of 186 mph (300 km/h).

Customers can start ordering the SLS AMG GT3 in autumn 2010, with deliveries scheduled to occur before the 2011 racing season.
