The M Sport option features a new aerodynamic package including numerous body components and the BMW Individual High-gloss Shadowline trim. The optional exterior paint shade of Estoril Blue metallic sets the model further apart, as do the 18-inch or 19-inch M alloy wheels. Inside, features such as the M door sill finishers, an M leather steering wheel and an M driver’s footrest create the right sporting ambience, while the M Short-gearstick (in models with a manual transmission), M Sport suspension and the optional M Sport brakes with contrasting blue paint finish define the model from a technical perspective. Dakota leather covers the interior including the front sports seats, while trim elements in Aluminium Hexagon with accent strips in either Estoril Blue matt or high-gloss black add the finishing touch.
