Having a hard time understanding the stream of inexplicable niche products coming out of the German automakers recently? Mercedes isn’t about to make things any easier. According to the latest print edition of Auto Motor und Sport, Mercedes has fallen so far down the segment-busting rabbit hole, it’s planning a “Shooting Brake” wagon version of its already-confusing four-door coupe, the CLS. Intended, of course, to compete with the BMW 5GT and Audi A7. Look for a concept inspired by this 2008 ConceptFascination study to debut at this fall’s Paris Auto Show. Then expect Audi and BMW’s designers to drop even more acid and talk their bosses into producing a landaulet-roofed, seven-door, MPV-coupe. You know, just to see if Mercedes makes one too.
