The Cadillac STS has a facelift in the works, likely for the 2008 model year. The big four-door gets a new, Escalade-inspired grille treatment, with a more detailed chrome treatment and a subdued mesh grille. The STS’s new face looks much lighter and more expressive than the current model’s — a subtle but effective update. New taillights ditch the full red lenses, in favor of styled LED lamps that complement the STS’s chiseled lines. The clear lenses have only a sliver of red reflector at the inside edges, but separate vertical LED strips glow red (braking) or orange (turn signals) in a truly eye-catching display. It appears that two additional reflective red strips have been added between the tailpipes, but it’s unclear whether this is a final production application, or merely a safety add-on for testing purposes. We expect similar updates to be applied to the CTS and SRX models, to tighten up Cadillac’s revamped family look.
