Mercedes has unveiled their stunning SL-Class 417 Mille Miglia, set to make its first public appearance next month at the Geneva Motor Show. Previously the SL320 and SL500 received the Mille Miglia treatment and now the SL400 and SL500 are getting their own special editions to celebrate the 60th anniversary of when an SL won in its class at the age-old open-road endurance race of the same name. Limited to just 500 very exclusive units, the 417 Mille Miglia features red accents on the front spoiler, rear apron, brake calipers and on the front and back alloys. Power for the SL400 edition comes from a V8 twin-turbo 4.6-liter engine that produces 333 horsepower. The Mercedes-Benz SL 417 Mille Miglia will officially make its debut next month in Geneva.
