Here’s the first official trailer for the astounding new Mercedes SLK 55 AMG, which makes its debut at Frankfurt Motor Show in a few weeks.

This mini SLS with its magical retractable roof gets a 422 PS – 530 Nm 5.5 liter V8 whcih helps it make 100 km/h from standing still in just 4.6 seconds. It is the same engine they put in E63, S63 and CL and CLS63, but in the little SLK it’s got no turbocharger. Plus, it gets start/stop and auto cylinder deactivation system. As a result it has an average fuel consumption of 8.4 liter per 100km.
