Spotted for the first time together are the probable prototypes of the 2 Series coupe (F22) and convertible (F23) while doing some winter testing. This gives us a very good idea on how these two models compare visually. Most likely, the F22 coupe seen here is a M235i model, due to the blue M Sport brakes and split dual black exhaust tips which are also seen on the M135i upon which the M235i is based.
