Lexus is set to release its new flagship LS sedan in San Francisco on Monday, but a trio of images have emerged ahead of schedule to give us a glimpse at the new model. That first dark 3/4 shot was released by Lexus on its Facebook page, but a Chinese website has also leaked out a pair of images showing the new LS 460 F Sport. What we can see is a revised LS adopting the brand's new spindle grille design and more aggressive lights front and rear.
