Lexus has announced the automaker will show off its new 2013 LS line in San Francisco on July 30. The shindig will be an invitation-only event, thought the premium automaker isn’t serving up too many details beyond the locale and the date. The LS family will eventually be available in a total of four variants, including a racier-looking F Sport model. We’re also holding out hope that eventually the much fussed-over LS TMG Edition we’ve seen racing around the NÃ¼rburgring recently will make the scene. Lexus has kept a pretty tight lid on what we can expect from the next-generation LS, though odds are designers will apply the company’s new spindle grille to vehicle’s fascia.
