Because of the controversy that will launch with this car [
the F32 coupe]. The F32 prototypes have underneath the camouflage, vacumned plastic sheets and foam moulds that hide the overall details, it makes the car look fatter and chunkier when underneath it combines the sportier profile of the E92 with the elegance of the 6er.
The good news is that underneath the disguise lies a very good looking car ,which really enhances the stylish and individual looks of the E92 with modern BMW design language and features but still keeping that individual look which distinguishes it from the 3er Sedan to be classified as the new BMW 4er Coupe And Cabrio.
The sleeker more dynamic roofline will also provide the basis for a very sexy looking four door Gran Coupe model which will bring the sleek sportiness , premium image and ambience of the 6er Gran Coupe to the Premium entry sports segment.
A 4er Gran Coupe is considered because of the scope of flexibility on the platform.
In style 4er Gran Coupe will be a 4er Coupe with standard front and rear styling, it will adopt a longer , flatter roof , conventional B-pillar and rear doors. The Platform for the Gran Coupe arrives from the China-only market 3er Li in a shortened version which is also found underneath the Gran Turismo 3er. This will benefit the interior and the length will provide adequate seating for four adults. In height the 6er Gran Coupe is lower than the new 3er (F30) current Coupe (E92) , 5er and 7er. The 4er Gran Coupe will be a few inches shorter than the 6er Gran Coupe.
Although a 4er Gran Coupe is not entirely a new idea. BMW did build a design proposal model of a four door E92 in 2005 but was rejected in favour of a more upmarket approach which eventually led to the illfated 2007 CS Concept. Which had the economic crisis not occurred , we would be seeing the production car around now. The 6er Gran Coupe is the "replacement" for the CS if you will. But with the next generation 7er they would like to bring a similar CS option to the 7er.
