| 2010 Infiniti M Seat Room and Comfort: Pros | ||
| Year | Body/Powertrain | Comment |
| 2011 | 4dr Sedan 420-horsepower 5.6L V8 7-speed shiftable automatic AWD |
Very comfortable up front. see full Infiniti M review |
| 2011 | 4dr Sedan 330-horsepower 3.7L V6 7-speed shiftable automatic AWD |
The footwells are very narrow for a car of this size. This is a side-effect of it being RWD. The "dead" pedal seems to be in the wrong spot, at least for me; it's too far to the right. On the plus side the air conditioned seats are great. It is possible to drive around in 90 degree weather wearing shorts, with the windows down, and feel comfortable. see full Infiniti M review |

Very envelopped and comfortable seat, have better padding, and seating posture is better than most of the luxry cars I tried. see full Infiniti M review |
| 2009 | 4dr Sedan 325-horsepower 4.5L V8 5-speed shiftable automatic AWD |
Huge rear seat with tons of space. Passengers routinly comment on how comfortable it is. Significantly more rear seat room then 5 series BMW. Ininiti G35/37 has more rear seat than the 5 series. see full Infiniti M review |

The fronts seats need more bolstering. The BMW 5 series has much, much better seats. If I could change one thing about the car, it would be the seats. Anyone considering this car should sit in the seat at least 30 minutes before making a purchase decision. see full Infiniti M review |
