Set to debut at the North American International Auto Show in January 2013, BMW will unveil the replacement for their 3 series coupe. The all new 4 series coupe concept was designed to fit between the 5 and 7 series, with styling cues from the current 6 series model. The new BMW 4-series features their trademark front twin-kidney grille, adding an optic fiber line off the hexagonal full-LED headlamps. In addition, the interior is also re-designed with Schiaparelli brown leather seats, cup holders and wooden trimmed door handles and dashboard. Check out images below, and as always, be sure to let us know what you think!
