The exterior features the complete M Aerodynamic bodystyling pack, including aggressive front and rear aprons, sculpted side skirts, high-gloss Shadowline exterior trim, and dark-tinted rear privacy glass. It rides on striking 18-inch M Double-spoke alloy wheels housing performance brakes, complemented by sharp LED headlights, LED fog lights, and dark-tinted LED rear light clusters.Inside, the cabin offers an exceptionally high-tech, driver-focused cockpit constructed from premium materials. Occupants are held securely by heavily bolstered Dakota leather front sports seats featuring built-in heating elements.

The center console is anchored by BMW's acclaimed iDrive infotainment system featuring a high-resolution display, factory satellite navigation, DAB digital radio, Bluetooth connectivity, and dynamic drive mode controls (ECO PRO, Comfort, Sport, and Sport+).
