Mercedes is to show an interesting four-door coupe concept car at the world's most important motor show, Auto China 2010. Dubbed the “Shooting Break Concept”, it's part Estate Car and part sports car with extra luggage. It has a sloping tail end, highly practical interior layout and 306 bhp direct injection V6 petrol engine. For all the innovation, it's the machine's dynamic full LED headlamps, due for series production this year, which are the stars. The Intelligent Light System has five functions – country lights, motorway lights, enhanced fog lights, active curve lights and cornering lights – and combines LED technology with Adaptive Highbeam Assist for the first time, leading to a completely new level of safety at night.
