2010 Infiniti M Interior

This interior review was created when the car was new. Some links may no longer point to an active page.

Auto writers are almost universally impressed with the cabin of the 2010 Infiniti M. The ambience is more modern than classic, with tight, smooth leather and satin-finished metal or rosewood. Those wanting a more traditional look might prefer the gathered leather of the Mercedes-Benz E-Class Sedan. Reviewers rave about the Infiniti’s comfortable seats, front and rear. There is less agreement, however, about the user-friendliness of the cabin electronics.

  • "M's cabin imparts a generally upscale feel, though some trim pieces are a bit dowdy for a premium car. Interior materials consist of satin-finish wood or real metal, precise-movement switchgear, and ample soft-touch surfaces." -- Consumer Guide
  • "The M35 has a spacious cabin that comfortably seats four adults. Materials quality is first-rate, with rich leather and pleasing wood appointments." -- Edmunds
  • "Interior surfaces aren't as sumptuous as those in the E-Class or Jaguar XF, but they're certainly upscale enough: There are leather wrappings around the door pulls and chrome runners along the steering wheel. The cabin trim — aluminum or optional wood — is the real deal, not synthetic." – Cars.com
  • "Overall, we found the living quarters in the M very pleasant." -- New Car Test Drive
  • "The M35 X and its siblings are all remarkably plush, featuring supple leather interiors trimmed with brushed aluminum, supposedly for more youthful, technologically oriented buyers; or finished with elegant rosewood for older, more traditional customers who know that life's bits and bytes are relatively meaningless without its poetry." -- The Washington Post


We found no complaints about the Infiniti M’s comfortable front and rear seats. Reviewers like the standard 10-way power-adjustable heated seats, as well as the firmer sport seats found on Sport model Ms. The Infiniti makes a good choice for those who routinely travel with adults in the back seat -- it offers more rear-set leg-, hip- and headroom than a Lexus GS, BMW 5-Series or Mercedes-Benz E-Class Sedan. An optional Premium Package adds reclining, heated rear seats and separate climate control for rear seat passengers.

  • "Generous room on supportive seats. The standard power tilt and telescopic steering wheel helps fine-tune driver positioning." -- Consumer Guide
  • "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." -- Edmunds
  • "Rear-seat passengers will be happiest with the Premium Package, which adds heated, reclining back seats. The controls are located inside the rear-seat center armrest. The package also includes a DVD system with an LCD that folds out of the ceiling and is controlled with a remote. Separate rear-seat climate control is included with this package. Even without the Premium Package, however, the rear seats offer plenty of leg and headroom." -- New Car Test Drive
  • "Sitting in the car is akin to fitting one's body into a rich, comfortable glove." -- The Washington Post

Interior Features

Reviewers are impressed with the quality of the materials found in the M, but there are few large luxury cars that we can’t say that about. What we can say is that shoppers need to spend time in the M to know whether it fits their body type and their tastes in technology. Reviewer comments on the electronics in this car vary. Some say its controls are logical, easy to understand and within easy reach. Others say they are dated, confusing and sometimes hard to reach. 

Infiniti is one of the last luxury automakers holding out against the trend toward a single user interface that controls every climate and entertainment function. In the M, each system -- navigation, climate and stereo -- has its own controls. Some reviewers prefer this layout. After all, it’s the way cars have worked for decades and most people can master such controls quickly. Others complain that the M’s dash is too heavy on buttons when compared to the cleaner layout of the Audi A6, with its MMI controller, or the BMW 5-Series, with its iDrive dial.

Curiously, the available rear-seat entertainment system (included in the Premium Package) provides flip-down LCD screens in the roof, SUV-style, rather than the more typical set mounted in the back of the front seats.

  • "Bright and clear gauges. Most controls are arrayed on keyboard-like shelf, and they are numerous enough to demand study…Some are a reach away, and sunshine can neutralize indicator lights." -- Consumer Guide
  • "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." -- Edmunds
  • "The navigation system's graphics are getting a bit dated, but its layout generally wallops the competition. Users can touch the on-screen commands or any of numerous shortcut buttons to zoom in or out, move the cursor around the map, go back to the previous screen, you name it.  Real-time traffic uses a feed from XM's NavTraffic subscription service to depict congestion levels with color-coded lines along the highway." -- Cars.com


Luxury sedans tend to have smaller trunks than less expensive cars, but the Infiniti M offers one of the larger trunks in its class. With the standard undersized spare tire in place, it offers 14.9 cubic feet of cargo space. With the optional full-size spare, the trunk shrinks to a very small 11 cubic feet. Unlike in the Mercedes-Benz E-Class Sedan and BMW 5-Series, the M’s rear seats do not fold down – meaning there is no way to expand the capacity of the trunk.  Interior storage is small, but reviewers say the same of most cars in this class.

  • "Good trunk volume, and its lid hinges don't intrude. A short aperture means drawer-like access. A small glove box and center console limit small-item cabin storage." -- Consumer Guide
  • "When equipped with the optional full-size spare tire it only holds 11 cubic feet of cargo." -- New Car Test Drive
