Earlier in the development process BMW was thinking about calling the 3-series coupe the 4-series, kinda like how the 6-series is a coupe that is mechanically similar to the 5-series but priced higher. So my guess would be that they gave it a separate chassis code at that point, and when they gave up on the 4-series idea, just kept the E92 designation.
