A 520hp Mercedes C63 AMG would certainly make its mark on the automotive industry.
Pistonheads user Tuvra has rendered a smooth cabrio variant of the Mercedes-Benz C63 AMG Black Series. The rendering was inspired by the model that appeared at the 2011 Frankfurt Auto Show last month in September. The rendering seen here was based on the Mercedes-Benz C63 AMG Black Series Coupe that was released some time ago, and has two versions: with and without rear spoiler adopted from the rare Mercedes CLK DTM racer.
Aside from the impressive and smooth lines seen here, the C63 AMG would be incredibly powerful as well, carrying the same 6.3-liter V8 that sits inside the coupe. A 520hp cabriolet with 457lb-ft of torque is certain to impress anyone within earshot. Though a cabrio version may seem a bit far-fetched at the moment you shouldn't rule it out, as a sedan variant was recently spotted undergoing some routine testing at the Nurburgring.
