The BMW 8 Series has just been revealed in two-door coupe form, but it appears there's a four-door Gran Coupe coming soon – going by a new set of patent renderings published in overseas media this week. A three-strong set of images was posted by website Motor1.com, said to be from the Brazilian National Institute of Industrial Property, depicting three versions of the new 8 Series: the coupe, a convertible, and four-door Gran Coupe.
