German automaker Mercedes has released a teaser for its new luxury concept car. Taking to social media, the brand posted an image of the silhouette of a two-door red coupe with a long sloping bonnet with the caption: "Hot and cool – almost 6m of ultimate luxury". Just as important to that caption is the Maybach logo featured on the car, confirming that the concept vehicle will be under Mercedes' luxury division. The car, which remains without a name for now, is expected to be fully unveiled at the Pebble Beach Concours d'Elegance on August 21.
