Here’s the official teaser clip for the new Mercedes-Benz SLK 55 AMG. It’s a car that boasts a 310kW normally aspirated V8 engine. It should sound totally nuts, right? Well, we wouldn’t know because Mercedes is too concerned about telling us how frugal the engine is: 8.4l/100km… blah, blah, blah. Just rev the thing so we can hear how good it sounds!
