The Porsche 911 better look out because Mercedes-Benz is reportedly working on a new sports car based on a shortened version of the 2010 SLS AMG’s platform targeted directly at it. The new Mercedes-Benz sports car will copy the SLS AMG’s aluminum construction but will lose the funky gullwing doors.

Instead, conventional front-hinged doors will be adopted in an effort to bring costs down. The new model will also pick up AMG’s next-generation V-8 engine, a 5.5-liter unit with direct-injection and turbocharging technologies and an output of around 500-horsepower. Acceleration times for the 0-60 mph dash are expected to fall around the 4.5 second mark.

The new sports car is tipped to be called the SSK AMG and is due for launch in 2014–an open top roadster version is an almost certainty.
