It's weird for us to report on leaked photos of a car that we've already driven, but we still haven't seen the completely finished 2012 Lexus GS. The sedan will make its public debut at the Pebble Beach Concours d'Elegance this coming weekend, but it appears that photos of the unwrapped prototype has already leaked onto the web.

Seen here in all-wheel-drive GS 350 guise, we must admit that the finished design is decidedly more sedate than what Lexus' teaser image led us to believe. Keep in mind, this car is the spawn of the attractive LF-Gh concept from the 2011 New York Auto Show, and while all cars lose a bit of sex appeal in the transformation from concept to production, the GS seems to have lost a bit more than we had expected, especially out back.

In any case, this looks to be the low-end of the range, not the F Sport or V8 model, and we'll hold our final judgments until we see the finished product in Monterey. Stay tuned for the full details this weekend.
