The 2012 Infiniti M is the most sporting in its segment of premium sedans, but its firm ride might be a turn-off for luxury-minded buyers seeking a more gracious driving experience.

The 2012 Infiniti M aspires to be both a luxury car and a sport sedan. This can be a difficult balance to strike, as shoppers in each of these segments often have opposing expectations. Sport-sedan shoppers usually prize a car that offers visceral engagement, whereas the average luxury-car shopper seeks a more gracious driving experience. In the end, the M delivers a mix that favors sport-sedan territory; it's the most performance-oriented choice in its segment, blending opulent accommodations with brawny engines and keenly attuned handling.

Available with rear-wheel drive or all-wheel drive, the M comes with a choice of three powertrains. Pleasingly, there isn't a dud among the bunch. The M37 has the smallest engine of the trio, a 3.7-liter V6 good for 330 horsepower, a rating that makes it more powerful than any other V6 in its class. At the top of the range is the M56, whose 5.6-liter 420-hp V8 makes it, like the M37, one of the most muscular choices in its segment.

Sitting between these two on the power spectrum is the new M Hybrid. The Hybrid combines a 3.5-liter V6 with an electric motor for a total of 360 hp. As with most other hybrid models, the M35h is a full hybrid, which means it can move under electrical power alone (up to 62 mph, says Infiniti, though that's likely with a very light foot). Electrical power is stored in a lithium-ion battery pack, and this in turn helps the M35h achieve both V8-like acceleration and fuel economy comparable to that of a four-cylinder sedan.

In addition to prodigious power, the M also offers a wide array of cutting-edge technology. You'll find comfort features like the Forest Air purification system, designed to guide air flow within the cabin so it resembles that of a gentle breeze, and performance features like Active Trace Control, which enhances the transition from braking to acceleration through corners. Meanwhile, the usual convenience and comfort amenities live in a cabin rich with handsome design and superior materials.

The M's biggest flaw is its ride quality, which might be too firm for some luxury-minded shoppers (especially when fitted with the Sport package). Though the Infiniti M has sporting intentions, rivals like the 2012 BMW 5 Series and 2012 Mercedes-Benz E-Class react to the road with more refined manners. The technology-oriented 2012 Audi A6 and affordably priced 2012 Hyundai Genesis are also worth checking out. But for shoppers interested in a luxury sport sedan that puts "sport" front and center, the M presents the most involving game in town.

The 2012 Infiniti M is a midsize luxury sedan available in three trim levels: M37, M35h and M56.
Standard on the M37 are 18-inch alloy wheels, automatic bi-xenon headlights, foglights, power-folding heated mirrors, automatic wipers, a sunroof, keyless ignition/entry, dual-zone automatic climate control, leather upholstery, heated eight-way power front seats, power lumbar support, driver memory functions, a power tilt-and-telescoping steering column and an auto-dimming rearview mirror. Also standard are a rearview camera, Bluetooth and a six-speaker stereo with a CD player, auxiliary audio/visual jack, an iPod interface and satellite radio.
The M56 adds a navigation system, real-time traffic/weather updates, voice recognition, heated and ventilated front seats, a heated steering wheel and a Bose 10-speaker premium audio system with digital music storage.
With the M35h, you get all the standard features offered with the M37, along with a hybrid powertrain, regenerative braking and unique instrument meters and display screens. You also get Infiniti's Vehicle Sound for Pedestrians (VSP), which compensates for the silent electric motor by generating a range of distinctive sounds designed to alert other road users to the car's presence.
Both the M37 and M35h are available with a Premium package that adds heated and ventilated front seats, a heated steering wheel, a navigation system (with voice control, real-time traffic and real-time weather) and a 10-speaker Bose stereo with streaming Bluetooth audio and digital music storage. The Deluxe Touring package adds a power rear sunshade, an in-car air purifier, upgraded leather upholstery and interior trim, and a 16-speaker Bose surround-sound stereo.
The M37 and M56 each offer a Sport package, although the content varies between trims. The M37 package includes 20-inch wheels, summer tires, sport-tuned suspension and brakes, four-wheel active steering, sport seats and steering wheel, and unique exterior styling elements. The M56 package includes the M37 features and adds a power rear sunshade, a Bose surround-sound stereo and an in-car air purifier; these additional amenities can also be purchased for the M37 as a Sport Touring package.
Buyers who choose the M's Technology package get adaptive cruise control, a lane departure warning and prevention system, a blind-spot warning system, a forward collision warning system, adaptive headlights and the "eco pedal" that provides feedback to the driver to encourage fuel-efficient driving.
The Infiniti M37 is powered by a 3.7-liter V6 that produces 330 hp and 270 pound-feet of torque, while the M56 is motivated by a 5.6-liter V8 that produces 420 hp and 417 lb-ft of torque. The M35h runs on a hybrid powertrain and offers a combined 360 hp from its gas-fueled 3.5-liter V6 and electric motor. Rear-wheel drive is standard, and the M37 and M56 are available with all-wheel drive. A seven-speed automatic transmission is standard on all three models and has four different shift modes (Standard, Sport, Snow or Eco).
In performance testing, the M37 went from zero to 60 mph in 5.9 seconds, while both the M56 and M35h made the same sprint in a very impressive 5.2 seconds. With rear-wheel drive, the M37's EPA-estimated fuel economy is 18 mpg city/26 mpg highway and 21 mpg combined, with the rear-wheel-drive M56 logging 16/25/19. Estimated mileage for the M35h is an impressive 27/32/29.
The 2012 Infiniti M37 comes standard with antilock brakes, stability and traction control, front side airbags, side curtain airbags and active head restraints. Included in the Technology package are a lane-departure warning and prevention system, blind-spot warning system and a forward collision warning system with intelligent brake assist. All three M models did very well in brake testing; the M37 stopped in 115 feet, the M35h in 119 feet and the M56 in 112 feet.
In government crash testing, the M37 earned an overall rating of four stars out of a possible five, with four stars for overall frontal crash protection and five stars for overall side crash protection. The Insurance Institute for Highway Safety gave both the M37 and M56 the best possible of rating of "Good" in the frontal-offset, side and roof strength tests.
The 2012 Infiniti M is a big car, but drives smaller than you might think. Its steering weights up less abruptly than that of other Infiniti and Nissan sedans, and it exhibits a downright feline willingness to change direction. All three powertrains offer the sort of abundant power and acceleration that makes them standouts in their segments.
Those wishing for an even more sharply tuned luxury sedan can select the Sport package's various performance upgrades. The combination of a sport suspension and 20-inch wheels, however, results in a firm ride that won't suit many buyers in the luxury segment.
Infiniti has given the M top-notch cabin design and high-quality materials. As with the car's exterior styling, the cabin's powerful lines call to mind the muscular curves of a bodybuilder flexing on the podium. Opting for the Deluxe Touring package adds seats upgraded with diamond-quilted leather and contrasting piping, unique "silver-powdered" wood trim, a faux-suede headliner and enhanced material on most primary touch points. In total, the M's interior challenges those of its established European rivals for refinement.
It also has the space and technology to compete with the Europeans as well. The cabin is quite roomy, offering generous space for occupants and a relatively tall greenhouse that provides good outward visibility. As for technology, it's hard to think of a rival that betters the M for all the available entertainment, comfort and safety technologies that can be had once you check all the options boxes. In particular, Infiniti's navigation and audio interfaces are some of the most user-friendly in the business. In terms of storage, the M has a 14.9-cubic-foot trunk; that drops to 11.3 cubic feet for the M35h.
The 2012 M is truly a blast on the road. With three eager powertrains, a comfortable interior and an impressive list of new and innovative technology to make your drive even better, there's blessedly little to complain about. Technologies like 4Wheel Active Steer and downshift rev-matching enhance the car's fun-to-drive quotient, while lane-keeping assist and blind-spot monitoring subtly help keep you safe. And the interior's a pretty nice place to spend some time – the seats are supportive, the dash intuitive and the M's iPod connectivity and searchability are among the best out there. The M Hybrid, which Infiniti claims is the world's fastest full-hybrid, delivers on its promise of combining the fuel efficiency of a hybrid with the engaging driving dynamics of a performance sedan.
Active Noise ControlEvery Infiniti M features Active Noise Control to keep aural unpleasantries caused by the engine or the open-air concert taking place in the adjacent vehicle out of the cabin. The system uses a ceiling-mounted microphone to detect and reduce low-frequency sounds for a more tranquil driving experience.4Wheel Active SteerFor increased agility and control at any speed, the 2012 Infiniti M employs an optional 4Wheel Active Steer feature that seamlessly adjusts the steering angle of all four wheels and the steering ratio according to the vehicle's speed.
Outfitted in rich, warm leather and high-quality soft-touch materials, the 2012 Infiniti M delivers an inviting in-cabin experience. The M's spacious greenhouse comfortably accommodates its occupants with 10-way power-adjustable and heated front seats, leather-trimmed seating surfaces and generous rear-seat legroom. The available Deluxe Touring Package takes the Infiniti M's already well-executed interior to a new level with semi-aniline leather-appointed seating, a 16-speaker Bose audio system, a suede-like headliner and striking White Ash silver-powdered wood trim sprinkled with flecks of real silver. The only sour note is the all-in-one control knob's inconvenient placement – a critical ergonomic flaw considering the module's extensive responsibilities over the audio, climate, vehicle information and convenience features.
Combining a muscular stance and a sleek profile, the 2012 Infiniti M is among the most stylish cars in its class. The Infiniti M's modern look is complemented by xenon headlights for both the low and high beams along with LED taillights. All Infiniti M models ride on standard 18-inch split 5-spoke wheels, while rear-wheel-drive (RWD) M37 and M56 models offer fender-filling 20-inch wheels. The Sport Package option adds a touch of aggression to the M's exterior with a smoked grille and headlight housings, unique front end, larger brakes and 20-inch performance summer tires.
The 2012 Infiniti M37 and M Hybrid come standard with Infiniti's Drive Mode Selector (Standard, Eco, Sport and Snow modes), leather seating, heated and 10-way power front seats, a 6-speaker audio system with USB connectivity for MP3/WMA players, Bluetooth, active noise control, rain-sensing windshield wipers, a 7-inch color display for audio/climate/vehicle settings, and keyless entry and start with driver memory settings. Moving up to the M56 adds a 5.6-liter V8, cooled front seats, a Bose 10-speaker sound system, a navigation system with SiriusXM NavTraffic and NavWeather, a 9.3GB hard drive for music storage and Bluetooth streaming audio. Safety equipment on every Infiniti M includes active head restraints, six airbags and automatic hazard lights that activate upon airbag deployment.
Regardless of powertrain, an Infiniti M can be outfitted to your liking. Available creature comforts include a Bose Studio Surround System with digital 5.1-channel decoding and 16-speakers, power rear sunshade, semi-aniline leather seating, silver-metallic wood trim, and a "Forest Air" system with breeze mode, which cleans and modulates the air flowing into the cabin. If you'd like your M37 or M56 to stand out, opt for the Sport Package, which adds 20-inch split 5-spoke wheels with summer tires, a sport-tuned suspension, 4-wheel active steering, sport brakes, magnesium paddle shifters, sport seats and unique front fascia, grille and headlight surrounds. All of the latest and greatest safety technology offered by Infiniti is encapsulated in the Technology Package, including adaptive cruise control, lane-departure warning and prevention, forward-collision warning, blind-spot monitoring and adaptive front lighting systems for increased visibility around dark corners.
The 2012 Infiniti M comes with a choice of three engines: a 330-horsepower V6 (the same engine found in the G37), a 420-horsepower V8, or a new 360-horsepower V6 hybrid. Every engine is mated to a 7-speed automatic transmission with a manual shift mode along with a race-inspired downshift rev-matching feature for non-hybrid models. Unfortunately, with great horsepower comes great financial responsibility. And despite average EPA fuel economy ratings, our real-world driving experiences have revealed that both the M37 and M56 have an exceptional thirst for fuel. Moreover, adding all-wheel drive to the M brings with it a greater penalty in fuel economy.3.7-liter V6330 horsepower @ 7,000 rpm270 lb-ft of torque @ 5,200 rpmEPA city/highway fuel economy: 18/26 mpg (RWD), 17/24 mpg (AWD)5.6-liter V8420 horsepower @ 6,000 rpm417 lb-ft of torque @ 4,400 rpmEPA city/highway fuel economy: 16/25 mpg (RWD), 16/23 mpg (AWD)3.5-liter V6 + electric motorHybrid system net horsepower: 360 EPA city/highway fuel economy: 27/32 mpg
The Manufacturer's Suggested Retail Price (MSRP) for the 2012 Infiniti M starts around $ 48,500 in base M37 trim and approaches over $ 70,000 for a fully-loaded M56. Adding all-wheel drive ups both prices by about $ 2,500. The new M Hybrid starts around $ 54,500 and tops out just under $ 69,000. The 2012 Infiniti M is competitive price-wise with the BMW 5 Series and the Mercedes-Benz E-Class, although the Infiniti offers more standard features than either German competitor. While the base Audi A6 offers less standard equipment, it does undercut the M's starting price by nearly $ 6,000. To be sure that you're getting the best deal on your M, be sure to check kbb.com's Fair Purchase Price for what consumers are actually paying in your market area. In terms of resale value, the M is expected to see above-average residuals over time, not quite as high as those offered by BMW or Lexus, but on par with Mercedes-Benz and Audi.
