BMW 4-series Coupe Concept Revealed BMW has officially revealed the all-new 4-Series Coupe Concept, following an earlier leak. Looking production-ready, the two-door coupe will make its public debut next month in Detroit. This is basically a three-door version of the 3-Series sedan but comes with several design tweaks that make it look sporty, yet elegant at the same time. Its wheelbase measures 2,810mm which makes it 50mm longer than that of the current 3-Series coupe. The front track now measures 1,545mm (45mm more) while the rear one stands at 1,593mm (up by 80mm). The 4-Series Coupe Concept is 1,826mm wide so it's 44mm broader than its predecessor. With a 1,362mm height, the concept is 16mm lower and at the same time it's longer than before, measuring 4,641mm. BMW installed a set of exclusive 20-inch light alloy wheels featuring a three-dimensional multi-spoke design that add to the car's sporty look. At the front we notice the hexagonal full LED headlights and the larger air intake in the front apron. The sloping roofline creates a natural transition into the rear, while the side windows help the slim and stretched theme. The low-slung appearance of the rear is completed by the stretched taillights located at the outer edges. Perhaps the most noticeable aspect of the rear is the bumper with its trim element in satin-finish aluminum that makes the car look premium. It also connects the two exhaust tailpipes in a dynamic sweep at the rear apron's outer edges. Moving inside the cabin, it's the traditional BMW driver-focused layout with the vital controls located ergonomically around the driver. Colors and material design have been developed by BMW Individual, including the two-tone Black and Schiaparelli Brown trim and light contrasting stitching.
