There was an interesting 2013 Lexus RX 350 on display at the Dallas Auto Show last week:
The front grille has been split, with a standard model upper grille and what looks like a F Sport lower grille. It brings to mind the Sport Appearance package that was mentioned briefly in Lexus USA’s press release about the 2013 RX — here’s a quote:
A Sport Appearance Package (not available on RX 350 AWD) is new for 2013 and offers an unique front bumper, halogen headlamps and 19-inch wheels with superchrome finish.
I don’t know if these wheels would classify as “superchome”, but the rest of the description fits — this brings the total available RX grille designs to three: Standard, Sport, and F Sport.
Update: I have received confirmation that this is indeed the new RX Sports Appearance package.
