What Changed:

An all-new Infiniti M bows for 2011. The new M is roughly the same size inside as its predecessor but wears significantly new styling outside and in. The wider new exterior has significantly more styling detail with pronounced fenders, protruding wheel arches and larger and more pronounced grille. The new model upgrades to the newest powertrains in the Infiniti lineup. The M37 has a 330-bhp 3.7l V6 under the hood, whereas the M56 equips the larger 420-bhp 5.6L V8. A seven-speed automatic is standard on all models. All-wheel-drive is offered with both the V6 and V8 engine (M37x and M56x).
