2012 INFINITI M56: A Detailed Overview
The 2012 INFINITI M56 represents INFINITI's ambitious foray into the luxury midsize sedan segment, offering a compelling blend of performance, sophisticated technology, and premium appointments. This generation of the M sedan, known internally as the Y51, aimed to challenge established German rivals with its distinct styling and potent V8 powerplant.
Highlights
-
Engine: The undisputed star of the M56 is its 5.6-liter V8 engine. This naturally aspirated powerhouse churns out an impressive 420 horsepower and 417 lb-ft of torque. Paired with a smooth and responsive 7-speed automatic transmission with manual shift mode and available Drive Sport (DS) mode, the M56 delivers exhilarating acceleration and a refined driving experience. The engine's ample power makes highway passing effortless and contributes to a dynamic, engaging ride.

Safety Features: INFINITI equipped the 2012 M56 with a comprehensive suite of advanced safety technologies designed to protect occupants and aid the driver. Key features include:
- Predictive Forward Collision Warning (PFCW): This innovative system monitors the vehicle two cars ahead, alerting the driver to potential forward collisions even if the car directly in front is not braking.
- Forward Emergency Braking (FEB): If PFCW detects an imminent frontal collision and the driver doesn't react, FEB can automatically apply the brakes to mitigate or avoid a crash.
- Blind Spot Intervention (BSI): Unlike typical blind-spot warning systems, BSI actively helps steer the vehicle back into its lane if the driver attempts to change lanes while a vehicle is detected in the blind spot.
- Blind Spot Warning (BSW): Visually and audibly alerts the driver when another vehicle is detected in the blind spot.
- Lane Departure Warning (LDW) and Lane Departure Prevention (LDP): LDW alerts the driver if the vehicle drifts out of its lane without signaling, while LDP can gently guide the car back into the lane.
- Adaptive Front Lighting System (AFS): The headlights swivel with the steering wheel to illuminate curves and corners, improving visibility at night.
- Around View Monitor (AVM): Utilizes four exterior cameras to create a simulated overhead view of the vehicle's surroundings, greatly assisting with parking and low-speed maneuvers.
- Standard airbags, anti-lock brakes, traction control, and stability control are, of course, present.
-
Trim Summary: The 2012 INFINITI M56 was primarily offered in two main configurations:
- INFINITI M56 Sport: This trim focused on enhancing the driving dynamics. It typically included the Sport Package, which added features like four-wheel active steering (4WAS) for improved agility and stability, performance-tuned suspension, 19-inch alloy wheels, and sport-stitched leather seats.
- INFINITI M56 (Standard): While not branded as "Sport," the standard M56 still offered a luxurious and well-equipped experience. It came standard with many premium features and provided a more comfort-oriented ride, though it could still be optioned with many of the advanced safety and technology packages.
-
Other Notable Aspects:
- Interior Luxury: The cabin is a testament to INFINITI's commitment to luxury, featuring high-quality materials such as genuine wood or brushed aluminum trim, soft leather upholstery, and an ergonomically designed dashboard.
- Infotainment and Technology: Available features like INFINITI's Intelligent Key with Push Button Ignition, Bluetooth connectivity, a premium Bose® audio system, and a navigation system with voice recognition provided a modern and connected experience.
- Distinctive Styling: The M56 boasts a bold and flowing exterior design that stands out in a crowded segment, characterized by its signature "double-arch" grille and athletic stance.
- Rear-Wheel Drive and Available All-Wheel Drive: The M56 came standard with rear-wheel drive for a more engaging driving feel, with an available Intelligent All-Wheel Drive (AWD) system for enhanced traction and stability in various weather conditions.
What to Expect
Owning a 2012 INFINITI M56 typically translates to an experience of refined power and sophisticated comfort. You can expect a smooth and quiet ride, with the V8 engine providing effortless acceleration for both daily commuting and long-distance journeys. The advanced safety features, while potentially intimidating to some, generally operate subtly in the background, offering peace of mind. The interior is a pleasant place to spend time, with comfortable seating and intuitive controls.
Maintenance: As with any premium luxury vehicle, maintenance for the M56 can be more involved and costly than for a mainstream sedan. Regular oil changes, fluid checks, and filter replacements are standard. The V8 engine, while robust, requires premium fuel. Certain advanced technology components, if they fail, could be expensive to repair. It's advisable to seek out a qualified INFINITI dealership or a reputable independent mechanic specializing in luxury Asian vehicles for service. Routine maintenance items like brakes and tires are comparable to other vehicles in its class.
Insurance: Insurance premiums for the M56 will likely be higher than for less powerful or less luxurious vehicles. Factors such as the vehicle's powerful engine, advanced technology, and luxury classification contribute to this. It's always recommended to obtain quotes from multiple insurance providers to find the most competitive rates.
Potential Considerations
- Fuel Economy: The M56's potent 5.6-liter V8 engine, while exhilarating, is not its strong suit in terms of fuel efficiency. Expect lower MPG figures compared to its V6 counterparts or competitors with smaller, turbocharged engines.
- Rear Seat Space: While the front seats offer ample room, the rear seating area can feel somewhat confined for taller adults, especially compared to some larger competitors in the segment. The transmission tunnel also intrudes on footroom.
- Infotainment System Usability: While feature-rich for its time, the M56's infotainment system might feel dated by today's standards. Some users might find the interface less intuitive than modern, touchscreen-dominated systems.
- Repair Costs for Advanced Technology: While the advanced safety and technology features are a major draw, their complexity means that any malfunctions or failures can lead to higher repair bills.
- Ride Comfort vs. Sport: While the M56 Sport offers a more dynamic driving experience, some may find its suspension to be firmer than a purely comfort-focused luxury sedan. Conversely, the standard M56, while more comfortable, might not satisfy buyers seeking ultimate sportiness.
Overall Summary
The 2012 INFINITI M56 is a compelling option for those seeking a luxury midsize sedan that prioritizes potent V8 performance, advanced safety technology, and a plush interior. It offers a distinctively styled alternative to more common German luxury cars, delivering an engaging and refined driving experience. While its fuel economy and potential repair costs for advanced systems are points to consider, for buyers who value a powerful engine and a wealth of cutting-edge features from its era, the M56 remains a strong contender.
