As numerous reports suggest, it remains to be seen if BMW will rename the M3 Coupe as the M4. Regardless of what they call it, graphic designer Jacek Kolodziejczyk (aka Iacoski) has created a set of renderings portraying what he thinks the hotly anticipate M division vehicle will look like.
Using the new BMW 3-Series (F30) sedan as his foundation, Iacoski has created a very plausible proposal by taking all of the familiar M design characterisics and skillfuly integrating them into the F30 as a coupe.
Notable details include the front bumper fascia design with built-in lower lip spoiler, blacked out grille, fender vents/M indicator lamp, side mirrors, scalloped side skirts, moderately flared wheel arches and muscular rear bumper design topped off by those signature quad exhaust pipes which look like a bunch of grenade launchers. The large flat graphite colored wheels add the final sporting touch.
Following the release of the 3-Series Coupe (possibly named 4-Series) in 2013. The M version (possibly named M4) would arrive a year later in 2014.
Speculation is rife as to which engine will be implanted. Just like the M5 going from V10 to twin-turbo V8, the same downsizing is expected for the current M3's V8 engine. Utilization of a six-cylinder engine is obvious, as well as the use of turbocharging, which currently permeates the entire BMW line-up, but whether it will be inline 6, V6, single turbo, bi-turbo or even tri-turbo is the big mystery.
One thing we do know is that the M3 (or M4) will do away with the torque vectoring differential, which can send varying amount of power to individual wheels, in favor of an electronically controlled differential similar to that found in the M5 (F10). This information comes by way of Road & Track magazine in an interview with M division head of product development, Albert Biermann.
