2012 INFINITI M56 Overview

As the top dog in the Infiniti sedan family, the powerful and refined 2012 Infiniti M56 is as raw as it is beautiful.

With a 420-horsepower, 5.6-liter V-8 that generates a whopping 417 pounds-feet of torque, the 2012 Infiniti M56 can accelerate with the best of them. The rear-wheel drive M56 is mated to a seven-speed automatic transmission, while an all-wheel drive version, the M56x is available (covered separately on this site). Customize your driving experience with Infiniti Drive, which lets you choose between various drivetrain settings, including Standard, Eco, Sport, and Snow modes, via a knob controller. The Eco mode is the most interesting because it indicates how efficiently you are driving with a yellow-to-green gauge and also provides resistance to the accelerator if it detects inefficient driving.

Other performance highlights include available four-wheel steering, sport-tuned suspension, and 14-inch front/13.8-inch rear disc brakes. The Infiniti M56 is a more-powerful version of the M37 and competes with the Mercedes-Benz E-Class, BMW 5-Series, and Jaguar XF. In terms of fuel-efficiency, the M56 receives 16 mpg in the city and 24 mpg on the highway.

The 2012 Infiniti M56 has a curved hood and a sleek front fascia with a low-sitting grille for an all-around sophisticated, yet modern look. Dual exhaust with polished tips, front fog lights, LED rear brake lights, UV-reducing solar glass, power-folding side mirrors, xenon high-intensity-discharge headlights, and 18-inch alloy wheels are standard, while 20-inch wheels and a darker grille and headlights are optional.

Inside, the 2012 M56 flexes its luxury credentials. Faux-leather-stitched dashboard panels, semi-aniline leather, and Japanese Ash wood trim interlaced with silver-powdered accents are just some of the available appointments. Standard features include: a 10-way power driver’s seat, DVD player, a two-channel, 10-speaker Bose sound system, hard drive navigation system, eight-inch WVGA color touch-screen display, voice recognition, XM Satellite Radio, USB/iPod connectivity, power sliding moonroof with one-touch open/close, climate-controlled front seats, and heated steering wheel.

In terms of safety, the 2012 Infiniti M56 is loaded with Lane Guidance, which alerts you when you start drifting into the adjacent lane. The optional blind spot warning system and forward collision warning system alert you when you are in imminent danger of colliding with object no matter where they are. Adaptive headlights that swivel in the direction of turns are also optional, while six airbags, active front head restraints, antilock brakes, traction control, and an electronic stability system are standard.

Immensely powerful, and laden with high-tech safety and interior features, the 2012 Infiniti M56 carries the brand’s flag with pride.
