2011 Infiniti M56 Review
Sporty luxury sedan for the refined driver.
Reviewed by Automotive on
The 2011 Infiniti M56 marks a new luxury sedan that replaces the Infiniti M45. Buyers expect a certain level of refinement when purchasing a luxury sedan. BMW and Mercedes-Benz traditionally meet this level, and now comes the Infiniti M56, adding outstanding design and current technology to the previous M45 sedan.
Not only is the engine in the M56 bigger now, its muscular styling hides a greater length and width. It also has a shortened height to provide aggressive proportions. Interior dimensions have not been altered much since it already offers more space than others. It has the distinction of being the most advanced technologically, with safety, comfort, entertainment, and performance features on the optional and standard equipment lists.
Infiniti offers Sport, Technology, and Deluxe Touring packages in addition to the standard items. The Deluxe Touring package adds a rear sunshade, an air purifier, quilted leather upholstery, and a 16- speaker surround- sound Bose stereo. This Touring package uses a trim of Japanese White Ash with inlays of real silver, leather door panels, and a head liner of suede, adding luxury and beauty to the M56. A Sport package does not apply to all-wheel drive or the Deluxe Touring package. The Sport package adds summer tires, 20-inch wheels, a sport steering wheel and seats, stereo with surround-sound, an air purifier, sport-tuned brakes and suspension, four-wheel steering, and a power sunshade. The Technology package includes cruise control, a warning system for blind spots, forward collision warning, adaptive headlights, and an eco-pedal to encourage fuel efficiency.
The M37 features more power than anyone needs, but the M56 provides the most power for those who want a lot more. With a 420-horsepower V-8 engine, the M56 cannot be matched by its in-class competitors. The biggest competitor of the M56 remains the less expensive M37, offering more horsepower for a V-6 sedan. Some buyers may think of the M56 as overkill, but for others it remains a sought-after attribute. Using better materials, elegant appointments, and a luxurious assortment of features and power accessories sets it apart from the lower-priced models.
Engines: 5.6-liter V-8, 3.5-liter V-6
Transmissions: seven-speed automatic
Models: Infiniti M56x, Infiniti M56 Base
For 2011, the Infiniti M56 sedans get a sleeker, smoother, and more luxurious exterior and the choice of more powerful, larger engines. Previous navigation systems show improvement and add new items such as a Forest Air system and Active Trace Control. All these features seem at home in a cabin that looks better-made and more attractive.
The Infiniti M56 looks a sleek, luxurious with 18-inch aluminum-alloy wheels, green-tinted glass to reduce UV rays from the sun, a sliding sunshade and moonroof, front fog lights, automatic headlamps, courtesy lights on door handles, and rain-sensing windshield wipers. The styling of the exterior has fender flares and a lowered stance, giving an aggressive and muscular look to this luxury sedan. Infiniti offers three colors to choose from for the exterior of your Infiniti M56: Platinum Graphite (Gray), Moonlight White, and Black Obsidian.
The interior of the 2011 Infiniti M56 features quilted leather upholstery and door panels, power seats, a heated steering wheel and front seats, a tilt wheel, power door locks, keyless entry, power windows, eight-way power seats, trunk release, a garage door opener, a rear window defroster, an analog clock, Japanese Ash trim with real silver inlays, floor and rear console vents, sun visors with vanity mirrors, a rear-view mirror with automatic dimming, an outside temperature display, map lights, seatback pockets, and a leather shift knob.
Performance & Handling
When driving on rough pavement, the vehicle loses some quality, but the M56 provides the most power for those who want a lot more. Infiniti offers a line of automobiles that combine performance, style, and luxury. Containing a 420-horsepower V-8 engine, the M56 outmatches its competitors.
The M56 comes equipped with anti-lock brakes, side and front airbags, head restraints to reduce whiplash, an anti-theft alarm, self-leveling headlights, front fog lights, and a post-collision safety system. Other safety options include blind spot intervention, cruise control, a collision warning system, stability control, and an impact alarm sensor.
