Why it stands out

The 2021 Nissan Altima stands out in the competitive midsize sedan market due to its blend of comfort, style, and innovative features. The Altima is now in its sixth generation and has made strides in retaining a loyal fan base, despite stiff competition from models like the Toyota Camry and Honda Accord. One of the key differentiators for the Altima is its impressive fuel efficiency, with a top-rated 28 mpg city/39 mpg highway for its standard 2.5-liter engine option. Additionally, the VC-Turbo engine available in the SR trim enhances performance dramatically, providing 248 horsepower—making it an engaging drive for those seeking more power.

The interior of the Altima is designed for both functionality and aesthetics, featuring high-quality materials and an intuitive layout. Safety is a priority for Nissan, exemplified by the standard inclusion of the Nissan Safety Shield 360 suite of systems. This includes essential features such as automatic emergency braking, blind-spot warning, and lane departure alerts, offering buyers peace of mind.

While the Altima's strengths are numerous, some owners have noted minor downsides, such as the absence of certain luxuries like a sunroof in base models. Nevertheless, for buyers looking for a stylish, efficient sedan with a good reputation, the 2021 Nissan Altima remains a solid choice.
