At the Pebble Beach Concours d’Elegance, Mercedes-Benz will unveil a concept with the nonsensical name Aesthetics Progressive Luxury.

So far, the only details about the machine come from a sculpture and enigmatic teaser video. It appears that the Aesthetics Progressive Luxury concept is a retro-inspired roadster that might takes cues from grand prix racers from the 1930s. Mercedes also suggests the vehicle has an electric powertrain.
