As part of a sixth-generation production cycle, which debuted for 2019, the 2020 Nissan Altima continues to be refined as one of the top four-door midsize sedans around. In addition to the all-wheel drivetrain option, which first appeared in the 2019 model, this iteration now has its full suite of driver assistance features expanded to more trims. In addition, the top-level trim now has the option of a memory function for the driver-side mirror positions.
