The next-gen 3 Series has only just been revealed but designer Nikita Aksyonov, the man behind some recent BMW X Cross renderings, has already turned out what looks like very accurate interpretations of the upcoming 4 Series Coupe and Convertible.

The new 3 Series may have gone the conservative route on the styling front, and aside from taillights that are sure to polarize opinion, it offers the usual visual mix of athleticism and quality that defines this core BMW offering.

As with most modern designs, the addition of some larger wheels and sportier bumpers greatly enhances the 3 Series' looks and Nikita has gone with the M Sport trim bits that were fitted to the launch model for his 4 Series renderings.

While BMW may shift product lifecycles around for some models, such as the new X5, the 3 Series has by and large stuck to a seven-year model cycle with a mid-life refresh at about the third-year mark. The sedans and wagons are always the first to launch followed by the coupe and convertible two years later.

The current 4 Series models were introduced in 2014 so we can expect their replacements to arrive by the end of 2020.

Judging from previous models, Nikita's renderings should be right on the money. By this point a new M model will also be part of the range and seeing as how electrification is the next big thing, we would expect hybrid engines to be an integral part of both the 3 and 4 Series models by then.
