Although Nissan and Infiniti won’t have an official presence at next week’s LA Auto Show, the luxury marque will unveil its 2011 M sedan at an event the night before the show and plans to webcast the proceedings at 7:00 pm PST on December 1.

Joining the thoroughly redesigned M on stage will be the updated 2010 Infiniti G and the oft-spied the 2011 Infiniti QX. Although official details haven’t been released for either model, a set of promo shots have already leaked out, showing a slightly reworked fascia equipped with a few organic creases, new foglamp surrounds and a tweaked grille. The QX receives a similar, although much more elaborate redesign, with a bulging hood, acres of chrome and a canted D-pillar.
