BMW had to comply with new Euro 6c emission regulations, and since it made some changes to the engines, it improved the rest of the 6-Series through a life-cycle-impulse in 2015.
After it reintroduced the 6-Series in 2003, BMW became a key player in the GT segment. But to keep the momentum, it changed it again with the third generation in 2011 and added a mid-life cycle refresh in 2015. While some modifications were barely visible, a trained eye would spot some differences.

At the front, the 2015 6-Series featured new LED fog lamps under the full LED headlights. BMW also replaced the front bumper with a new one that sported a wide center grille in the apron flanked by two side-scoops for additional cooling needs. In the middle, on the lower part of the bumper, the carmaker installed the radar system for the automatic cruise control. On its sides, the 2011 model featured a chromed trim around the window line, while the 2015 model didn’t. The facelifted version featured a new bumper design at the back, with reflecting red stripes above the middle section.

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. But there was still not enough room for three passengers in the back or two tall adults for longer distances.

Under the hood, BMW installed Euro 6-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.
