In 2015, BMW introduced a life-cycle impulse for the 6 Series Gran Coupe to comply with new emission regulations and brought a refreshed look.
With the 6 Series Gran Coupe, BMW offered a proper answer for the Mercedes-Benz CLS. It introduced the four-door version in 2012, a year after its two-door stablemate. Three years later, the carmaker refreshed the entire lineup introducing new technologies and a more aggressive design.

At the front, the car featured new LED fog lamps under the full LED headlights. Its grille sported nine vertical slats on each side of the kidney grille, one less than on the non-facelifted version. A side-to-side “mouth” found its place on the lower side of the bumper. The flared wheel arches and the rear horizontal lines from the back of the car created the image of a wider car. That effect was enhanced by a chrome strip in the bumper trim. For the six-cylinder versions, the rear apron featured larger surrounds for the tailpipes.

Inside, the 2015 model featured new piano-black trims on the center console, surrounding the climate control buttons. Its high-bolstered front bucket seats were covered in Dakota leather with an option for Nappa. In the back, the carmaker kept the two-seat layout with a very tall transmission tunnel. Instead of a middle passenger seat, BMW installed a folding armrest.

Under the hood, BMW installed Euro 6c-compliant engines with either six or eight cylinders. A 313 hp turbo-diesel was specially built for European customers, while the U.S. buyers got only the twin-turbocharged 3.0-liter or the twin-turbocharged V-8. All versions were available with rear or all-wheel-drive and featured a standard eight-speed automatic gearbox.
