It's been over a year since we first caught a glimpse of the new gullwing super coupe from Mercedes-Benz, and in the months that followed, we've seen it cloaked in Viper sheetmetal, its doors open to the world and a few shots of the interior. While it's still unclear whether the SLC will wear a Mercedes badge or an AMG logo (or both), development continues unabated as engineers flog the SLC through –15-degree weather in an undisclosed arctic locale.

We do know that motivation will be provided by a twin-turbocharged V8, likely the same 6.2-liter engine being fitted to all of M-B's AMG-badged products, and that 600 hp will be fed to the rear wheels thorough a seven-speed automatic gearbox. The chassis will be made of aluminum, and carbon fiber will make up the majority of the exterior panels. Sales of the SLC are expected to begin in 2010, assuming the world doesn't implode on itself in the meantime.
