The German luxury car manufacturer likes to do things bigger – bigger coupes, bigger sedans or bigger wagons – for its 3 Series/4 Series.
But the 2015 BMW 4 Series Gran Coupe seems to be even bigger than all, especially than its flagship 3 Series sedan.
As you can also see in the pictures, the 4 Series Gran Coupe is longer and wider by around half an inch, but shorter in overall by around an inch and a half, compared to 3 Series sedan.
More than that, things with the 4 Series Gran Coupe are even better, with the car also sporting a longer roofline, a more sculpted rear haunches and lower stance.
Inside the 2015 4 Series Gran Coupe though, the space volumes should feature the same numbers as the 3 Series sedan, but perhaps with some insignificant decrease in headroom and rear legroom.
As for the powertrains, they are completely taken from the other 3/4 Series lineup. The 428i uses the BMW`s preferred 2.0-liter turbocharged inline-four engine with 240 horsepower and 255 pound-feet of torque.
On the other hand, the 435i is equipped with the more powerful 3.0-liter turbo-six engine, generating a pure 300 horsepower and 300 lb-ft.
