What's New for 2009

The 2009 Infiniti M35's V6 engine has been tweaked to provide a bit more power this year. It's also matched to a new seven-speed automatic transmission on rear-drive models.


Much like an Olympic decathlete, the 2009 Infiniti M35 attempts to master several disciplines all at once. And like said decathlete, this mastery involves a subtle mix of athleticism and finesse. Serving as Infiniti's midsize offering, the M35 has a cracking V6 and sharp handling abilities to support its sporting credentials, while a luxurious interior, high-tech features and available all-wheel drive make this sedan ideal for daily commutes.

For 2009, the M35 has trained exhaustively in the off-season. Under the hood is a revised 3.5-liter V6, which now makes 303 horsepower, up from 275 hp last year. On rear-drive models, the V6 is matched to a new seven-speed automatic transmission, with the M35x continuing on with last year's five-speed auto. Curiously, the M35 didn't get the new (and more powerful) 3.7-liter V6 used in this year's G37, the M35's smaller cousin. The all-wheel-drive G moves to the seven-speed tranny, too.

That bit of sibling rivalry aside, the M35 is good enough to take a place on the podium among midsize luxury sport sedans. It doesn't quite reach the top all-around achievements set by the BMW 5 Series, nor does its road isolation match up to the Acura RL's or Lexus GS 350's. Hyundai's new Genesis is another vehicle to consider, as it provides much of the luxury experience but without the luxury price tag. These are subtle differences, however. For buyers wanting a sedan that can do everything well, the 2009 Infiniti M35 is worth consideration.

Body Styles, Trim Levels, and Options

The 2009 Infiniti M35 is a midsize luxury sport sedan available in two well-equipped trim levels. The base model M35 and the all-wheel-drive M35x have standard features that include 18-inch alloy wheels, a sunroof, adaptive xenon headlights, leather upholstery, 10-way power front seats with heating and cooling, driver-seat memory settings, dual-zone automatic climate control, Bluetooth and a six-speaker audio system with a six-CD/MP3 changer and an auxiliary audio jack.

Options are grouped into packages with slight variations between the M35 and M35x. The sport package, which is not available for the G35x, includes 19-inch alloy wheels with high-performance tires, sport body styling, rear active steering, a sport-tuned suspension, aluminum trim that replaces the standard wood accents, and sport front seats. The technology package adds a hard-drive-based navigation system, an upgraded eight-speaker Bose sound system with a 9GB music server, a rearview camera, iPod connectivity and voice-activated controls. An advanced technology package can be added that includes a premium 14-speaker surround-sound system, a lane departure warning system and adaptive cruise control.

A mobile entertainment system is available in conjunction with all previous packages, but only for rear-wheel-drive M35s. This package basically consists of a rear entertainment system. Finally, a premium package is available that includes all of the previous packages (minus the sport package) and adds power reclining and heated rear seats, rear climate and audio controls, and a power rear sunshade.

Powertrains and Performance

The M35 is powered by a reworked 3.5-liter V6 that cranks out 303 hp and 262 pound-feet of torque. The standard transmission is a new seven-speed automatic, though the M35x continues on with the previous five-speed variant. Both transmissions feature manual shift control and rev-matched downshifts. Fuel economy comes in at an EPA estimated 17 mpg city/25 mpg highway and 19 mpg in combined driving. The M35x drops slightly to 16/22/18 mpg.


The Infiniti M35 comes standard with antilock disc brakes with brake assist, stability and traction control, front-seat side airbags, full-length side curtain airbags and active front head restraints. The advanced technology package adds safety features including an advanced lane departure warning system that alerts the driver of unintended lane drifting and then applies light brake pressure to specific wheels to maintain lane placement. Also included is an array of sensors that detect an impending crash and tighten the seatbelts. The Insurance Institute for Highway Safety gives the 2009 Infiniti M35 its highest mark of "Good" for the car's protection in frontal offset and side impacts.

Interior Design and Special Features

The M35 has a spacious cabin that comfortably seats four adults. Materials quality is first-rate, with rich leather and pleasing wood appointments. Even in base trim, the front seats are firm and supportive, with plenty of power-adjustable settings. Opting for the sport package enhances the M's sporting persona by adding more aggressive bolstering for the front seats as well as distinctive interior trim. The gauges are bright and legible, but the plethora of center stack controls is a bit busy-looking. Even so, you'll probably find them easier to operate than some of the menu-based systems in German luxury sedans.

Driving Impressions

The 2009 Infiniti M35, with its newly massaged V6, should provide plenty of power for most drivers. For the few who desire a bit more oomph, there's always the V8-equipped M45. Considering the M35's superb handling capabilities, the ride quality is surprisingly comfortable and compliant, though some with a penchant for full-luxury cars may find it a bit harsh, especially when equipped with the sport package. On the open highway, road noise is attenuated to acceptable levels but not as silent as a competing BMW 535i or Lexus GS 350.

What Others Are Saying

Customer Reviews

Near perfect balance between luxury

by on
Vehicle: 2009 Infiniti M35 4dr Sedan (3.5L 6cyl 7A)

Consumer Reports hit the nail on the head when they rated the M35 their #1 mid-size luxury/sport car. Bought a 2009 M35 w/ Nav & Tech pkg in Feb 2010 after my 2005 Honda Accord was destroyed by a fallen tree. Owned: one year. Never a problem. Great handling, pickup, & very reliable. Guess it helps to keep up with maintenance. Radio & 6-disc CD player was adequate for me. Nav, easy to operate once I learned it. Decided to trade because of lousy fuel mileage (17-18 mpg), wanted lower pymts, & a smaller car. Bought 2005 BMW 330i sedan - very satisfied so far. If Infiniti would spend more time improving gas mileage and less time designing needless gadgets this car would fly out of dealerships.

2009 infiniti m35x

Vehicle: 2009 Infiniti M35 x 4dr Sedan AWD (3.5L 6cyl 5A)

I bought a used M35X from the dealer last month. It had 18,000 miles on it and was a rental car in its previous life. I have had the car for about 1 month now. The car drives really well. The acceleration is very good. The interior is spacious and well designed. This car has the Premium Technology package and is full of cool features. It is the top pick in the Consumer Reports evaluation for mid-size luxury cars. Reliability is next only to the Lexus LS 430 according to Consumer Reports. The only issue is with the Rear Crash ratings from IIHS which is "Poor" compared to an Acura RL which is rated Good on all the tests. The Road Noise can be lower although the engine hum is enjoyable.

Worst technology on the market

Vehicle: 2009 Infiniti M35 x 4dr Sedan AWD (3.5L 6cyl 5A)

I have been a Lexus customer for 12 years. We shopped around and found the M35X. They pushed their technology so much at the dealership we felt it had to be as good as Lexus if not better. Boy were we wrong. Unfortunately I now have 38 months of this nightmare left. I returned an 06 Lexus GS, which my phone the Palm Pre had no trouble pairing with the Bluetooth. My 09 M35X does not work at all with these phones. Static all the time and that supposedly great Bose radio that lowers and loudens itself at will comes on and off during a conversation. Then there is the nav - what a waste of money. No points of interest. Been lost a lot lately. $53000 really Infiniti. Entire system was replaced by dealer, no luck.

Outstanding car

Vehicle: 2009 Infiniti M35 4dr Sedan (3.5L 6cyl 7A)

I just traded a 2006 M45, which I loved, for this car. I got the M35 to save a few bucks and get better gas mileage. The M35 with the 7 speed is almost as quick as the M45. The car rides great and is fun to drive, I got the Tech and Advanced Tech with Sport Packages. Love the DVD player, new 7 speed transmission with sport mode, hard disk music box, IPOD hook up, navigation and touch screen. All but the DVD and navigation are new features my 2006 did not have. I got the Blue Slate with black interior and it looks great!

Worth the price

Vehicle: 2009 Infiniti M35 4dr Sedan (3.5L 6cyl 7A)

This is my second M35S as I also had a 2006. The ride in the 2009 is a little stiffer, but still comfortable for a car with 19" performance tires. The increase in power along with the 7 speed transmission makes for a great combination. The gas mileage is about the same as the 2006 at about 20mpg in mixed driving. Looked at Jaguar FX, Lexus GS, Acura TL and Audi A5. None could come close to the lease deal. Best value in its class.

Rattles, rattles, rattles

Vehicle: 2009 Infiniti M35 x 4dr Sedan AWD (3.5L 6cyl 5A)

How much do you have to pay these days for a car that does not rattle? In the first few thousand miles I have return this car for 3 rattles. Rattles in the dash and doors are making this car a major regret.
