2.5 series? stupid idea to have called it a 2 series and 4 series
"Gran Coupe" is the convention that BMW came up with to deal with the sedans that are derived from their coupes. Odd numbered cars will have 4 doors, even numbered cars will have 2 doors, and even numbered cars with a "Gran Coupe" at the end of their name will also have 4 doors.
