Classic BMW Coupe Dimensions Despite being BMW's smallest model, the new 2 Series is bigger than its predecessor. The entry-level 230i is 4.3 inches longer, 2.6 inches wider, and an inch lower. The more powerful M240i xDrive is 3.5 inches longer, 2.6 inches wider, and 0.1-inch lower. Both variants' wheelbase is two inches longer than before. What hasn't changed is the long hood, short rear deck silhouette: a classic BMW hallmark. The new sheet metal is more athletic than before thanks to three-dimensional surfaces and a generally more sculpted appearance. The muscular flared fenders and power dome, turbine-style kidney grille, and a low-slung stance emphasize the coupe's driving attitude.
