2011 INFINITI M56 Exterior

2011 INFINITI M56 Overview

The Infiniti M series has undergone a complete makeover, including the all-new 2011 Infiniti M56 midsize luxury sedan. The M56 retains its sport-tuned performance, while adding more horsepower, a sleeker, bolder style and a plethora of impressive technology features.

Nissan’s luxury brand, Infiniti has replaced last year’s M45 with the all-new M56.  The 2011 M56 ditches last year’s V-6 and boasts a 95-horsepower improvement with a 5.6-liter, 420-horsepower V-8.  That beast offers 417 pounds-feet of torque and is mated to a seven-speed automatic transmission with manual shift mode.  Speaking of modes, the 2011 M56 offers four distinct driving modes that allow you to program your drivetrain settings to Standard, Eco, Sport or Snow modes. 

Not only is there more power, but the M56 receives 16 mpg in the city and a more-efficient 25 mpg on the highway.  The M56 is available in one trim level, which is rear-wheel drive, but an all-wheel drive version, the M56x is available.  The midsize luxury sedan segment is strong and the 2011 M56 has to compete with the Mercedes-Benz E-Class, BMW 5 Series, Jaguar XF and Lincoln MKS.

When it comes to the exterior, gone is the safe, sterile design of last year’s model.  The 2011 Infiniti M56 incorporates fluid lines that run from front to back; a more sculpted hood and distinctive grille and rear fascia. With the changes to the engine and exterior, the M56 not only drives sporty—it looks sporty. Dual exhaust pipes, sunroof, keyless ignition/entry, foglights, power-folding side mirrors, xenon headlights and 18-inch alloy wheels come standard. 

Because the 2011 M56 has only one trim (the Premium package comes standard), there are four optional packages to choose from: Deluxe Touring, Sport, Sport Touring and Technology.  Inside the M56, high-quality materials mesh with a luxurious design that ripples with purpose.  Dual zone climate control, 10-way heated power driver’s and front-passenger’s seats, leather-appointed interior with Japanese Ash wood trim, USB/iPod/Bluetooth connectivity, backup camera, updated navigation system with 8-inch touch-screen display, Lane Guidance and 3-D building graphics and XM NavTraffic with real-time traffic information come standard.  The standard Premium package also takes your audio experience to the next level with a 10-speaker Bose premium audio system, 9.3GB Music Box hard drive and in-dash DVD player.

Safety is the name of the game for the 2011 Infiniti M56.  Six airbags, an electronic stability system with traction control, antilock brakes and active front head restraints come standard. Infiniti’s Lane Departure Prevention system and Blind Spot Intervention system are included in the Technology package. 

The all-new 2011 Infiniti M56 incorporates a sleeker exterior, luxurious interior, tons of technology features with jaw-dropping power and handling, giving you one of the most impressive driving experiences to date.
