Lexus has unveiled its GS 450h sedan for the 2010 model year. Following in the footsteps of the 2010 Lexus LS, the GS will see little in the way of major improvements, but its overall look will be enhanced thanks to styling tweaks both front and rear.

For 2010, the GS 450h hybrid will be receiving a few unique styling cues to set it apart from its gasoline-only counterpart. Most notable is revised front grille that brings the 2010 GS 450h more in line with the 2010 LS 600h L and the all-new HS 250h.

A few new exterior color options will also be added for the 2010 model year.

Inside, the GS will see a slightly revised interior, including a new audio and navigation system. Lexus says the 2010 GS also features a number of safety improvements.
