Diehard BMW fans may cringe at the idea of the 3 Series splitting into two lines – 4 Series for coupes and 3 Series for sedans – but soon, things may get even more convoluted. The spy shots below appear to show the upcoming 4 Series Gran Coupe, a 4 Series model that’s been given the four-door coupe treatment.
Though this test mule could pass for a 3 Series Gran Turismo with heavier camouflage, a few differences pop up when you compare it to the 3 Series GT tester we spotted last week. On this tester, the sloping roofline meets with the trunk to form a slight notch. The GT test mule, on the other hand, had a roofline that was raked almost to the very rear of the car. The roof also appeared taller on the 3 Series GT, and the front end was left uncovered, whereas this latest test mule hides its front end details under heavy camouflage. In addition, the front end camo is similar to that used on 4 Series testers we’ve seen in the past.
Just as the 6 Series Gran Coupe tops the non-M 6 Series range, the 4 Series Gran Coupe, if produced, would be the flagship model of the 4 Series and 3 Series lines. As such, you can expect it to carry a significant price premium over the standard two-door 4 Series. The 4 Series Gran Coupe will also likely be longer than the 3 Series sedan, though all 4 Series models are expected to share drivetrain options with the 3 Series, including the turbo 2.0-liter I-4 and turbo 3.0-liter I-6.
Should BMW should offer a four-door coupe-like variant of the 4 Series, or will adding another model just crowd the lineup? Share your thoughts on the BMW 4 Series Gran Coupe below.
