What changes are in store for the 2010 Infiniti G37 facelifted sedan? Details and photos inside.

Infiniti will introduce the facelifted 2010 Infiniti G37 sedan at the Los Angeles Auto Show later today.  The car will appear alongside the company's new M37 and M56 models with a tweaked exterior that matches some of the styling seen on the M series.

The freshened model has several exterior changes, including a redesigned front bumper that incorporates fog lights and a black honeycomb lower grille.  The upper grille is slightly modified, with the top and bottom bars extending further than the rest.  In back, a new rear bumper gives off a more squared appearance, despite the rounder indentation above the exhaust.  The decklid also appears a bit boxier, with a smaller spoiler, and LED lighting.

Inside, new features include a white colored theme that includes new gauges and instrument panels.  They used a "Shodo" aluminum trim, inspired by Japanese calligraphy, to replace the previous "Washi" trim.  Lighter-toned leather and glossier accents are also available.  The Bose Studio on Wheels audio system, with three-way speakers, ten-inch woofers, and new subwoofer comes standard.

The 2010 Infiniti G37 uses the same 3.7-liter V6 engine introduced on the '09 model.  That model replaced the G35, which was first launched back in 2006.
