BMW is playing around with its lineup these days, providing a couple of models with different names, depending on their body styles. The first to get that differentiation was the 3-Series , with the sedan and station wagon versions keeping the 3-Series name and the coupe and convertible getting tagged as 4-Series models. The BMW 3-Series sedan has already debuted, but the coupe and convertible models are still undergoing testing proven by the new series of spy shots for the upcoming 4-Series Coupe .
The future BMW 4-Series Coupe will be a smaller version of the current 6-Series with design elements borrowed from its 3-Series sedan brother. But the fact that it is a coupe model will make it sportier and more aggressive. The model will be immediately recognized as a BMW thanks to the usual design features: new-style exposed, three-dimensional BMW double kidney grille and a larger rear window.
Under the hood of the 4-Series, BMW will place the same engines as in the sedan version - including two petrol and two diesel - with output going up to 306 HP for the most powerful version - the 435i.
