A GLC wearing Michigan Manufacturer plates has been spotted out and it seems to be missing exhaust pipes.
Mercedes execs have made it perfectly clear that they will be making a concious shift from diesels to fully electric and hybrid electric powertrains, and that was even before VW blew the doors of diesels public perception.
We've seen the GLC 350 e PHEV already, and it certainly sports two massive chrome exhaust 'tips', so we're fairly certain this isn't just the US market version. Although Mercedes has never made mention of a GLC EV in the past. Its also missing the flap on the rear bumper for the charging port. We would imagine that the GLC PHEV and GLC Full EV would share the positioning of the charge port.
