*Update* Lexus has released another image of the concept this time showing the interior. You can see it in the gallery above. 

Lexus is being very cagey about a new concept that it is bringing to the North American International Auto Show in Detroit on January 9, 2012. All it is saying is that the concept was designed at its Calty design lab in California, and that it represents a future design direction for Lexus.

Lexus said the same thing about the design for the new GS-series of cars when they were introduced earlier this year. It is possible the the concept could carry design cues from the GS.
