Mercedes Paints AMG GT 4-Door Tennis-Ball Yellow to Honor Roger Federer

• Mercedes has created a special one-off AMG GT 4-Door to honor tennis player Roger Federer's retirement.

• The special model is a GT63 S E-Performance hybrid that's painted in tennis-ball yellow.

• Federer will play his last match today at the Laver Cup, a team competition held in London.

Mercedes offers a wide range of colors as part of its Designo customization program, but this particular shade of tennis-ball yellow is not one of them. That's because this special one-off version of the AMG GT 4-Door was created specially to honor tennis great Roger Federer's retirement, which he recently announced on social media. Federer is scheduled to play his last match today at the Laver Cup, a team competition held in London of which Mercedes-Benz is a sponsor.
