About the 2013 INFINITI M

4th generation M (Y51, launched for 2011), third model year and last year before the 2014 rename to Q70.

INFINITI positions the M as a large luxury sedan with a stronger driver-focused edge than a comfort-first cruiser. The pitch centers on strong engines, rear-drive-based proportions, a roomy upscale cabin, and a long list of technology features without losing everyday usability. What sets the M apart is that buyers could choose three distinct personalities from the same sedan: V6 sport-luxury balance, V8 power, or hybrid efficiency with genuinely quick acceleration.

The M37 is the core sport-luxury sedan, with a 330-hp V6, heated leather seats, a moonroof, and either rear-wheel drive or all-wheel drive in the M37x. The M35h pairs a V6 with an electric motor for 360 hp, while the M56 and all-wheel-drive M56x use a 420-hp V8 and add navigation, Bose audio, and climate-controlled front seats.
