It's been a while since we've seen the upcoming BMW 4 Series Gran Coupe out testing, but we're sort of inclined to ask "Why?" yet again. After all, the 4 Series is what the new 3 Series-based coupes and convertibles will be called, so the idea of another four-door version just sort of seems redundant. In other words, just how different will a 4 Series Gran Coupe be from a 3 Series sedan, aside from perhaps a more rakish roofline or a four-passenger seating configuration? Probably not much, but BMW clearly thinks it can use the additional bodystyle to rake in some extra profits.
Anyway, back to these spy shots. No more of the 4GC's skin has been revealed since the last time we saw it, but we fully expect it to share a lot of its design DNA with the 3 Series sedan, not to mention the attractive 4 Series coupe concept that bowed at this year's Detroit Auto Show.
Powertrain options should carry over direct from the 3 Series line, so we expect to see 428i and 435i models on hand, packing turbocharged four- and six-cylinder engines, respectively. We're sure that BMW's xDrive all-wheel drive will be available, and who knows, we could even get a 428d version with the new 2.0-liter turbodiesel four that debuted in the 328d at the New York Auto Show last week, or even an M4 variant.
The 4 Series coupe is expected to launch later this year, so expect to see the 4CG shortly thereafter.
