Infiniti's "swoopy anger" design language has made it to the M line, and InsideLine got some seat time in the V8-powered, rear-wheel drive, M56 and the six-cylinder, all-wheel-drive M37x. The M56 is, of course, the monster of the two and kinda looks it. The black hue and 20-inch wheels makes all the difference on the outside, giving the 400+ horsepower V8 sedan the sporting chops to make you go "Hmmm." The interior continues the curves, and the contrasting color scheme appears to create a very rewarding three-dimensional cabin.

The M37x is reportedly worth about 325 hp, and will end up being the middle in the range, just above a rear-wheel-drive model below it. Seven-speed autos will get the power to the ground in every model. Edmunds wasn't allowed to give driving impressions, but they did get lots of photos, so head on over to get a good look at the next M.
