Mercedes-Benz SLS AMG

The Mercedes-Benz SLS AMG  is luxury grand tourer car devloped by Mercedes-Benz AMG to replace the SLR McLaren. It's  the first Mercedes car designed in-house by AMG and is described by Mercedes as a spiritual successor to the 300SL Gullwing.

It was unveiled in 2009 Frankfurt Auto Show. It will hit the market for sale in mid 2010 in Europe and in The US mid-2011 , the SLS AMG is featured as the cover car for the upcoming PlayStation 3 racing game Gran Turismo 5, and will also serve as the safety car for the 2010 Formula One season.

The SLS AMG has been desined to be a modern 300SL Gullwing revival.with a long bonet, the passenger compartment is close to the rear axle and the rear of the car is short. The SLS AMG will also adapt the feature of wing doors that will swing open upwards on gas struts, not in a mix of upwards and forward like the SLR. The doors must be closed manually as AMG engineers decided against auto-closing systems because the systems would have added 41 kg to the car.In case of a roll-over, the doors can be fully detached to allow the occupants to leave the vehicle. The designer is Gordon Wagener whose family once had a 300SL.
