2011 Infiniti M56 At-A-Glance

The all-new 2011 Infiniti M56, which was launched at Infiniti retailers nationwide in March 2010, embraces the essence of all things Infiniti – style, performance, luxury, craftsmanship and technology – taking each to the highest levels ever for Infiniti’s halo sedan.

The 2011 Infiniti M is available in M37 and M56 model designations, with rear-wheel drive or Infiniti’s Intelligent All-Wheel Drive system. The M37 features a 330-horsepower 3.7-liter V6 engine – with increased power and fuel economy versus the previous generation M35’s 3.5-liter V6. The M56 also offers more power and better fuel economy from an all-new 420-horsepower 5.6-liter V8 (versus the previous generation M45’s 4.5-liter V8). Both the M37 and M56 engines feature Infiniti’s advanced VVEL (Variable Valve Event & Lift) system and all models are equipped with a standard 7-speed automatic transmission. A special Sport Package, offered on rear-wheel drive models, offers 4-Wheel Active Steer (4WAS), sport-tuned suspension, Sport Brakes and 20-inch wheels and tires.

The new M is also a showcase for Infiniti’s advanced, user-focused technologies, carrying on the tradition of the previous generation M. New technologies include Infiniti Drive Mode Selector, a four-mode driver-selectable control of throttle and transmission mapping that helps optimize vehicle performance; Active Noise Control, which reduces undesirable engine harmonics, providing a quieter cabin; Blind Spot Warning (BSW), which helps alert the driver if another vehicle is detected in the blind spot area; Blind Spot Intervention™ (BSI), a world’s first system that, in addition to the Blind Spot Warning, helps the driver return the vehicle back toward the center of the lane of travel in the event of unintended drift; Forest Air™ system, which helps reduce the intrusion of unpleasant odors into the cabin and provides natural “breeze-like” airflow; Eco Pedal, which provides driver feedback to encourage eco-driving behavior; and Active Trace Control, which adjusts engine torque and the control of braking at each of the four wheels to help enhance cornering performance.

The 2011 M also offers a next-generation Infiniti Hard Drive Navigation System, Bose® Studio Surround® premium audio system, Intelligent Cruise Control (Full-Speed Range), Lane Departure Warning (LDW) and Lane Departure Prevention (LDP) systems, Distance Control Assist (DCA), Intelligent Brake Assist (IBA) with Forward Collision Warning (FCW) and Front Pre-Crash Seat Belts.

The M’s dramatic, sports styling provides a coefficient of drag of just 0.27 Cd, while the roomy, comfortable interior environment features standard leather-appointed seating, standard Japanese Ash wood trim or available silver powdered genuine White Ash wood trim and available premium audio and climate control systems. Key standard features include Infiniti Intelligent Key with Push Button Ignition, XM® Satellite Radio, Bluetooth® Hands-free Phone System and power sliding glass tinted moonroof.
