The upcoming coupe version of the new BMW 4-Series has been caught testing one more time, and this time our spy photographers also managed to catch a shot of the interior. Also, the new prototypes reveal the functioning air vent in the front fender.
Set to replace the coupe and convertible version of the new 3-Series, the 4-Series will be a little smaller than the 6-Series, but with design elements inspired by the 3-Series. Spy shots have also revealed that the vehicle will be a few inches longer than the sedan version and will feature a more aggressive front end with the new exposed, three-dimensional BMW double kidney grille and a larger rear window.
Under the hood, the model will keep the lineup found in the 3-Series: a choice of four engines - two petrol units and two diesels - with the top version being the 435i with an output of 306 horsepower.
The new BMW 4-Series Coupe will be put into production in July 2013, so the official launch date is getting closer.
