There are a lot of flagship sedans out there, and we admit that the Infiniti M-series has been a bit off our radar. Yeah, it's had rear-wheel drive and some nice powertrains, but it hasn't really been aimed at our market. The M56 is new for 2010, and Infiniti has definitely captured our attention.
Our test car had the available 5.6-liter V8 backed by a seven-speed automatic transmission that automatically matches revs. More optional goodies: the Sport Touring package (upgraded tunes, mostly), the Sport package (245/40R20 tires, sport suspension and four-wheel active steering), and R Spec high-friction brake pads. (Seriously, it really came with upgraded pads, a $370 option.)
