Four Mercedes-AMG One Hypercars Spotted Testing Together

Mercedes kicked off deliveries of the AMG One at the beginning of the year, but it looks as though prototypes are still being tested. No fewer than four were caught on camera in Granada, Spain at a rest stop. These were accompanied by a GT 4-Door Coupe in the 63 S flavor that also belonged to the peeps from Affalterbach. Seeing four is a special occasion considering the F1-engined hypercar will be a rare sight, with only 275 customer cars.
