Infiniti's 5-series rival used to be a nice, but anonymous car. After hooning it through Southern California's canyons, that's no longer the case. Now, the 2011 Infiniti M is Japan's Jaguar.

When the Infiniti M debuted it was a curiously designed Japanese Nissan hiding a powerful V8. Perhaps fearing the looks have caught up with the power, the 2011 Infiniti M's new 5.6-liter V8 pumps out 420 Louis Vitton-branded horses.

Following our spy photos of the 2011 Infiniti M56 are some live shots of the M56 and M37 on the prowl.

Infiniti revealed the new M with a foam model and some virtual reality voodoo last month, but now Brenda Priddy's unexpectedly stumbled upon the 2011 Infiniti M56 out-of-doors and the sheet metal looks curvaceously sensual in real life.
