The M37 is easily recognizable by its muscular fluidic design, standard HIDs and 18 inch split five spoke alloys; while on the inside the M offers an Infiniti Intelligent Key with illuminated push button starter, a six speaker AM/FM/XM/CD/MP3 stereo with USB audio inputs, 7 inch color display with rear view monitor, leather wrapped power adjustable front buckets, Japanese Ash wood trim and a power sliding/tilting one touch glass moon roof with sliding sunshade.
The $49,850 Infiniti M37x adds intelligent all wheel drive for $49,850. The $59,100 M56 gets the same great features, but with the power of a 5.6 Liter V8 making 420 HP and 417 lb-ft of torque while returning 16 MPG around town and 24 MPG at speed, and the $61,600 M56x gets all wheel drive, while the $53,700 M Hybrid moves thanks to the combination of a 3.5 Liter V6 with Infiniti Direct Response Hybrid with a 50 kW electric motor and a lithium ion battery pack that is good for a combined 360 HP and 258 lb-ft of gas burning torque and an additional 199 lb-ft from its electric companion and gets an estimated 27 MPG in the city and as much as 32 MPG on the highway; however Infiniti left out the downshift rev matching feature. The Infiniti M is an IIHS Top Safety Pick.
