As promised Infiniti gave a “virtual” preview of the upcoming 2011 M today at the Pebble Beach Concours d’Elegance. Using state-of-the-art 3D video mapping technology, an image of the new M was projected onto a molded styrofoam shape, revealing the third-generation of the sedan that is both sporting and luxurious.

The new design is a big step for the M as it gets design cues from the Essence Concept that was launched at this year’s Geneva Auto Show.

Infiniti is keeping tight-lipped about most of the details, but we do know that both an M37 and M56 model will be offered. The M37 will use the 3.7-liter V6 as found in the current G37 and make roughly 330hp. As for the M56, as the name suggests it will get a 5.6-liter V8 and deliver in excess of 400hp!

One technology highlight of the car is a new blind spot alert system that will not only detect if there is a vehicle in the next lane over, but it will also then help bring the M back into its lane.

Both models will be available starting in the Spring of 2010 as 2011 models in 32 markets around the world.
