The BMW 4 Series (F32) is a compact executive coupé manufactured by the German automaker BMW. First official details of the 4 Concept 4 Series were released to the public by an official press release on 5 December 2012, detailing the intention to replace the current 3 Series coupé with a new 4 series line to further differentiate the more sporty coupé. This move mirrored the strategy of arch rival Audi, who spun off the coupé and convertible versions of the A4 into the separate A5 nameplate some years earlier. The BMW 4 Series is also available in a retractable hard-top convertible form (F33) and in the Gran Coupe body style (F36) since the 2014 model year.
The 4 Series Coupe shares all technical features with F30 3 Series. The interior is almost the same as in the 3 Series except for the 2+2 seating configuration, and the exterior also shares the overall styling of the 3 Series. Its wheelbase is 110.6 inches, two inches longer than the 3 Series coupe and identical to the 3-series sedan. BMW has increased the front track by 1.8 inches, for 60.8 inches, and 3.1 inches to the rear, for 62.7. Its overall width is 71.9 inches, 1.7 inches wider than the 3 Coupe, and 0.6 inches lower, at 53.6. Overall length is 182.7 inches. The BMW 4 Series has made its debut in Detroit, United States at the North American International Auto Show in January 2013.
