BMW is preparing for a more controversial design future, with the facelifted 7-Series and new X7 acting as a sign of things to come.

The first Bimmer that’s going to fully grin at us though is the all-new 4-Series (together with its M3/M4 siblings), as previewed by the BMW Concept 4 at the Frankfurt Motor Show last year.

To give us a better understanding of what the final product might look like, Kolesa came up with these renderings, depicting both the front as well as the rear end of the new 4-Series.

The front end matches what we’ve seen so far pretty well, especially the styling in and around the grille. That being said, the headlight graphics are a bit more angular in real life, while the mesh grille down in the spoiler region features lines instead of the render’s honeycomb pattern.

Other than that, the new 4-Series should look just like this when viewed from the front, and will finally give the Audi A5 a run for its money in terms of grille size – or at least it will try to, because the Audi’s will still be bigger.

As for the rear end, that’s a whole different story. All we have to go on, officially, is the Concept 4, which is what the designer used in order to complete this digital exercise. What he did here was to essentially “dumb down” the styling of the concept in order to make it more production-friendly.

As such, the rear is flatter than the Concept 4’s, while the taillights look more sensible – as do the graphics, although the pattern is similar.

When it finally does break cover, the all-new BMW 4-Series will be offered with multiple different engines. We expect to see a 430i model powered by a turbocharged 2.0-liter four-pot with 255 HP and 295 lb-ft (400 Nm) of torque, plus an M440i variant with a 382 HP turbocharged 3.0-liter six-cylinder unit. The 473 HP (480 PS) all-new M4 will arrive at a later date.
