The Infiniti M Sedan has a base model in the M37. This can be found for $47,700. This has a 3.7L V6 engine, a hill start assist device for uphill starts, power steering that responds to the speed of the car and front seats that can be adjusted in ten ways. These seats can even adjust themselves in accordance to memory settings in the car. A glass moonroof is also used with an automatic opening and closing function and a tilt option.
The M37x AWD, which is available for about $50,000, is the next trim. This uses an all wheel drive feature to help control the vehicle even in snowy conditions. However, its mpg is 17/24, a rating slightly less than what the M37 uses.
The M Hybrid is the next of the Infiniti M Sedan choices. This vehicle, which is available for about $54,000, uses a 3.5L V6 engine with a 50 kW motor. This is used to create a 27/32 mpg rating. It even includes a Vehicle Sound for Pedestrians, a sound playback item that is used to state when the vehicle is coming near someone. This is useful because the hybrid version of the Infiniti M Sedan is very quiet.
The M56 is the high end version of the Infiniti M Sedan. This vehicle, which is available for a little less than $60,000, has a 5.6L V8 engine with 420 hp. It includes a ten speaker Bose sound system with support for DVD and MP3 playback functions. It also uses a larger navigation screen.
The Infiniti M56x AWD is the last option. It is like the M37x AWD in terms of its drive but with the stronger engine and sound system that the standard M56 already has.
