2009 Infiniti M Review

By

The 2009 Infiniti M distinctively blends sport, luxury and performance characteristics with V6 or V8 power. After a light freshening last year, the 2009 M35 and M45 continue to cruise through the crowded luxury field, bypassing more expensive sedans from Japan, Europe and America. The M series offers a choice of rear-drive or all-wheel-drive and a number of cutting-edge features such as a Lane Departure Prevention (LDP) system. Rated by the EPA as a full-size sedan, with interior space that nearly matches an Audi A8, BMW 7 Series and Mercedes S-Class, the Infiniti M is priced closer to the smaller Audi A6, BMW 5 Series and Mercedes-Benz E-Class counterparts – along with key Japanese mid-size rivals like the Acura RL and Lexus GS and the lone American entrant, the Cadillac STS. The Infiniti M's high-value and high-content formula is further reinforced by excellent reliability and strong customer satisfaction ratings.

You'll Like This Car If...

If you're in the market for a sport sedan with plenty of room, spirited performance and loads of comfort and convenience touches, any member of the 2009 Infiniti M lineup is worth a test drive. Those with distinct enthusiast leanings should find the V8-powered M45 with a Sport Package particularly attractive.

You May Not Like This Car If...

Even in this latest incarnation, the Infiniti M's styling cues remain somewhat understated, perhaps too much so for buyers with more flamboyant tastes. If you're one of the vanishing breed who still believes that any proper sport sedan simply must have a manual transmission, an M35 and M45 in any guise just won't fill your bill.

What's New for 2009

The V6-powered M35 gets a significant bump in horsepower, from 275 to 303. The rear-wheel drive M35 also receives a new seven-speed automatic transmission, while the all-wheel drive variant receives HID head lamps and Infiniti's Adaptive Front lighting System.

Driving the M
Driving Impressions

Although the specific driving characteristics of each model vary by engine and powertrain configuration, all variations on the M theme come standard with a genuinely engaging personality and offer an...

... impressive combination of comfort and control that should please a wide range of potential buyers. Based on the latest version of Nissan's lauded FM (Front Mid-ship) platform, also used in the 370Z and Infiniti G37, the M matches its nicely-sorted fully-independent suspension with well-weighted and quick-responding power steering. Those commendable dynamic qualities get ratcheted up a tangible notch on rear-drive models fitted with the optional Sport Package. Although the heavier all-wheel-drive M35x and M45x models sacrifice a bit of enthusiast appeal, Nissan's outstanding AWD system can seamlessly transfer torque from front-to-rear and side-to-side as changing traction conditions warrant, making it a feature well worth considering for those who live outside of the Sun Belt.

Bi-xenon Adaptive Front lighting System (AFS)
Standard on all M models, these high-intensity headlamps are linked to the steering system and can angle their brilliant blue-white beams into a corner to provide an even better look at what lies ahead.

Optional Rear Active Steer (RAS)
Included in the Sport Package, Rear Active Steer varies the geometry of the rear wheels in response to both road speed and driver steering inputs to deliver even more immediate and positive reactions during spirited cornering.

2009 Infiniti M Details

The spacious Infiniti M cabin has a contemporary classic flavor highlighted by supple leather upholstery with African rosewood or textured-aluminum accents. The main gauges reflect the latest Infiniti white-and-purple lighting motif for even greater legibility, and supplemental functions can be accessed by logically arrayed switchgear on the instrument panel's center stack – or by a user-friendly controller that displays information on a 7.0-inch color LCD screen. Both front seats feature 10-way power adjustability, the fixed-back, contoured rear bench provides generous head and legroom for adults in the two outboard spots while a pull-down center armrest conceals a modest pass-though opening to the M's 14.9 cubic-foot trunk.

Exterior

A subtle yet wide-ranging exterior revamp last year gave the M a bit bolder character, but it's still no standout. Its crisply rendered nose touts an edgy grille, standard fog lamps and shapely lower air inlets. Around back, smooth sheetmetal flows onto wide fenders and a high-profile decklid, which is punctuated by integrated taillamps that complement a tidy fascia. Both M35 and M45 models come with 18-inch aluminum wheels mounted with V-rated 245/45 all-season tires, but stepping up to the Sport Package upgrades that to 245/40R19 high-performance tires on unique alloy rims and includes more aggressive front and rear soft-trim contours, integrated side sills and charcoal-colored headlamp bezels.

Notable Equipment
Standard Equipment

Both the 2009 Infiniti M35 and M45 have all of the luxury appointments you'd expect in a premium sedan – and more. Complementing leather and wood and aluminum trim are a bounty of power assists plus dual-zone climate control, 160-watt AM/FM/CD/MP3 audio with six-disc changer, Intelligent Key remote locking and ignition, one-touch power moonroof and a power tilt and telescoping steering column capped by a four-spoke wheel with switches to operate the audio, cruise control, phone and vehicle information functions. All versions come with Vehicle Dynamic Control (VDC), anti-lock brakes (ABS), Brake Assist (BA), Electronic Brake force Distribution (EBD), corner-following bi-xenon adaptive headlamps and front, front-side and side-curtain airbags.

Optional Equipment

Tiered option groups allow personalization of any M model with the best of everything available from Infiniti. The four key packages, in ascending order, are Technology, Advanced Technology Mobile Entertainment and Premium. Included in those packages are voice-recognition DVD-based navigation, a RearView backup monitor, Intelligent Cruise Control, Preview Braking, Lane Departure Warning, Lane Departure Prevention, two levels of Bose premium audio systems, a 9.3-gigabyte Music Box hard drive, single or dual-screen rear-seat DVD video systems, heated and power-reclining rear seats and rear air conditioning. Enthusiasts can opt for the Sport Package, which includes a tauter suspension with Rear Active Steer, plus 19-inch wheels and tires, sport seats and unique body trim.

Under the Hood

Smooth and sophisticated, the M35's 3.5-liter V6 and the M45's 4.5-liter V8 are enthusiastic, albeit somewhat thirsty, powerplants. Made of lightweight aluminum and featuring variable valve timing to maximize operating efficiency, both are backed by a responsive five-speed automatic transmission (seven-speed on the rear-drive M35) with intuitive electronic controls that adapt to a driver's individual style, plus a neat throttle-blipping feature that matches engine rpm to vehicle speed for even smoother downshifts. With 303 horsepower and 262 pound-feet of torque, the V6 propels an M35 from zero to 60 miles per hour in just over six seconds - or slightly more for the heavier all-wheel-drive M35x. Rated at 325 horsepower and 336 pound-feet of torque, the larger V8 in the M45 drops that interval into the mid-to-high five-second range.

3.5-liter V6
303 horsepower @ 6800 rpm
268 lb.-ft. of torque @ 4800 rpm
EPA city/highway fuel economy: 17/25 (RWD), 16/22 (AWD)

4.5-liter V8
325 horsepower @ 6400 rpm
336 lb.-ft. of torque @ 4000 rpm
EPA city/highway fuel economy: 16/21 (RWD), 14/20 (AWD)

"My personal company car, well cared for and pampered. The leather is in great condition, no cracks or stains. Carpet is slightly worn with light staining. No accidents, new windshield, detailed recently, usual road rash and light rust on the body that you would expect for a high mileage car. Drives as well as the day I bought it."

Best car I ever owned until I bought my new Tesla.

"For those of you who want a great-looking, reliable, sporty-handling sedan, that won't break the Bank when it's time for a repair, look no further. To be honest, I have always been more of a European Car guy, mainly for the road feel and having that last bit of connected-ness to the pavement that typically has been the sole province of Italian and German cars. ( Sorry British Car fans, most of your Country's offerings are either too unreliable, or just plain absent in the USA...) But this M, and smaller stablemate, the G series have more than proven to me and many Euro car freaks that even though I am still a huge BMW fan ( pre-2004 for 3 & 5 Series ) this 5-Series competitor has more than met my expectations. The vehicle is very attractive, dives into corners like a longer/wider 350Z, has an incredibly comfortable and stylish interior with a killer audio system (not the base unit) and an easy to use Navigation / HVAC system. The only very minor nitpick I have is that the orange guages look a bit cheap ( like they came from a Maxima ) and out of place on a vehicle that is supposed to compete with BMW and Mercedes Benz. Buy a Bimmer if you have a lot of money to shell out for repairs, or you're the shallow type and just want a BMW for the image. But buy an Infinity and I promise you'll be more than happy with it!"

"Better car than my Mercedes. Love this car. Like driving a rocket ship. Not as fast as a BMW 5 series, but not as expensive either. This 09 listed at 54K and I bought in 2013 for 28K with 21,000 miles on it. It is fully loaded. Great car!"
