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.

As an F Sports model it features a styling package with distinctive front and rear bumpers, side skirts, and faux rear diffuser with larger tailpipes. Expect the updated range to include the LS 460 (with its 4.6-liter V8) and LS 600h (with 5.0-liter V8 hybrid powertrain) in both standard and long-wheelbase versions. We'll have to wait until after the weekend for the full details and more photos, so watch this space for more.
