The headlights can automatically go on or off based on the light intensity in the car's area.
The glass can keep UV rays from getting into the vehicle and can keep glare problems from being an issue.
The front windshield wipers can sense rain and work automatically based on how much rainfall gets on them.
The seats in the front row can be heated but the M56 models can work with cooling functions to go with heating functions.
The seven inch screen that shows vehicle information is easy to read. The eight inch WVGA touchscreen for the M56 mdoels is even better.
The airbags in the Infiniti M Sedan can inflate based on intensity and on whether or not any people can be sensed in the seating areas where the airbags are located.
The car is available in multiple colors and with six different interior color and trim choices with different leather and wood finishes in each choice.
The amount of time it takes for the Infiniti M Sedan to move from one shift pattern to the next takes a bit.
It costs extra to get twenty inch wheels. These wheels are not available on all models either.
The capacity of the Hybrid version of the Infiniti M Sedan is not as strong as with other models. Standard models have 14.9 cubic feet of cargo space but the Hybrid only has 11.3 cubic feet. Also, the Hybrid can only fit 18 gallons of gas versus the 20 that the other models can handle.
All models weigh more than or close to 4,000 pounds.
