New renderings of the upcoming BMW M3 and M4 surface on the interwebs. Our sister magazine Bimmertoday, with the help of rendering artists, give us a look at how the new M models might look like.

For the F80 M3 sedan illustrated below the artist has missed a few things, mostly due to simply transposing design cues from the 1 Series M Coupe to the M3. The rendering also shows the F80 M3 with a bulge on the hood, a design element currently available on the E9x M3 models. At the rear, the 1M diffuser is used in these computer generated images.

The powerplant found under the hood is a newly developed 3.2 liter unit, still inline-six, which has its fundamentals in the current M3 engine, the S65 V8.

The engine is rated at 450 hp and with a new performance package it could reach 480 horsepower and a top speed of 300 km/h.

The third rendering gives us a side shot of a potential design of the F82 M4 Coupe. The base design will come from the new 4 Series Coupe and it will differentiate itself from the 3 Series family through a sleeker front apron and slightly redesigned headlights. Compared to the previous renderings, this one gives the M4 the bumper style from the newly launched M6 Coupe, with its typical large air intakes.

Same as our previous observation, the M4 renderings showcases a hood bulge which will likely not going to be present in the production car.

The F80 M3 comes to market in 2013, followed a year later by the F82 M4.
