A month ago, a new BMW prototype was spied for the first time. At the time, given its fastback shape and substantial similarities to the 3 Series GT (3GT) prototypes we've been spying for months, we deemed it to be a 3GT with some camouflage removed or altered. But, the prototype has been spotted again and the additional looks at the prototype have us convinced that it is indeed the F36 4 Series Gran Coupe (4GC) being tested.
Here's a brief analysis of the clear differences between the two prototype models. The comparison photos below should also be helpful.
•The hood and cowl height and hood slope of the 4GC prototype is different than the 3GT.
•The shorter front bumper overhang on the 4GC.
•The roofline of the 4GC prototype differs from the 3GT - it's lower and sleeker, and the line is a smoother parabolic shape, without the sudden transition that the 3GT roofline has where the windshield joins the roof.
•The front windshield is more raked on the 4GC than 3GT.
•The B pillar of the 4GC appears wider than on the 3GT.
•The bottom door cutlines on the 4GC are horizontal, compared to the 3GT's upsweeping cutline (as it approaches the rear tires).
•The 4GC has much more of a trunk deck area, with the rear roofline ending much earlier than on the 3GT.
Codenamed as the F36, the 4 Series Gran Coupe will top the 3-Series/4-Series range just as the 6 Series Gran Coupe does for the 5-Series/6-Series range. Like the 6 Series Gran Coupe, it will be the flagship of the non-M series line for the 3/4-Series lineup and will be priced accordingly. For reference, the 2013 640i Gran Coupe is priced at a $1600 premium over the 2013 640i Coupe.
Like the 6 Series Gran Coupe, the 4 Series Gran Coupe combines the convenience of 4 doors (and larger rear passenger cabin) with the sleek roofline and silhouette of a coupe. It will share the upcoming 4 Series Coupe (F32)'s overall styling, just as the 6 Series Gran Coupe shares with its coupe counterpart. The 4 Series coupe recently revealed its kidney grille design (photos), which we will also see on the 4 Series Gran Coupe. It will also share the same engine offerings as the 4 Series coupe and convertible.
