The Lexus GS F has been around in one form or another since 1991, offered as a mid-size four-door with a solid dose of opulence in the cabin. The latest fourth-gen model dropped in 2011, giving the lineup a little extra sportiness when the mood is right. Now, Lexus is using the platform to pay homage to it’s F-branded trim levels. In case you weren’t aware, Lexus’ F models make up the quickest of the automaker’s stable, with the singular letter tacked to the trunk added as a nod to Japan’s world-famous Fuji Speedway. Lexus first started making F models back in 2008, and now, a full decade later, it’s offering up two special edition F’s to celebrate the anniversary.
