The new model will lose the SLS AMG's gullwing doors, trading them in for more conventional ones, and eventually spawn a convertible variant. In terms of power, we could see something like AMG's 5.5-liter twin-turbocharged V8 engine along with an entry-level option in the guise of a V6. The top-of-the-line SLC AMG could produce as much as 500hp, giving the new model a distinct advantage over its rival Porsche 911 and the Aston Martin
V8 Vantage. As this is just the first test mule ever spotted of the Mercedes-Benz SLC AMG, it will absolutely look much different when it eventually makes its way out of the German company's factories in 2015.
