The 2021 model year sits in Nissan's most refined generation of the Altima, introduced in 2019 with a full redesign that brought sharper styling, a quieter cabin, and upgraded tech.

2021 Nissan Altima Performance and Engine

Under the hood, this Altima runs a 2.5-liter four-cylinder engine paired with Nissan's Xtronic CVT automatic transmission and front-wheel drive. The 2.5L naturally aspirated engine produces around 188 horsepower and 180 lb-ft of torque — more than enough for confident freeway merges on the 22, the 5, or the 405 that Orange County drivers know all too well.

The Xtronic CVT is designed to keep the engine in its most efficient power band, which translates to an EPA-estimated 28 MPG city and 39 MPG highway. That kind of fuel economy matters in California, where gas prices consistently run above the national average. The FWD configuration keeps the drivetrain simple, which also means lower long-term maintenance costs. Day-to-day driving in stop-and-go traffic is smooth and effortless thanks to the CVT's seamless power delivery.

Nissan Altima Features and Interior

The 2.5 SV trim steps above the base S model with a meaningful set of upgrades that improve comfort and convenience on every drive.

Technology and Connectivity

The SV includes an 8-inch touchscreen infotainment display with Apple CarPlay and Android Auto integration, so your phone connects seamlessly from day one. Bluetooth audio and hands-free calling come standard, and the system is intuitive enough that you're not fumbling through menus while navigating surface streets in Anaheim or Santa Ana.

Comfort and Convenience

Inside, the Altima SV offers a well-appointed cabin with available heated front seats, a dual-zone automatic climate control system, and a remote engine start feature — a genuine quality-of-life upgrade during hot Southern California summers. The rear seat offers class-competitive legroom, making this an easy choice for small families or carpool commuters. Nissan's ProPilot Assist driver aid system is available on this generation, adding adaptive cruise control capability that makes freeway driving significantly less fatiguing.

Safety Features

Nissan Safety Shield 360 is a standard suite on the 2021 Altima that includes automatic emergency braking, rear automatic braking, blind-spot warning, rear cross-traffic alert, lane departure warning, and high beam assist. These aren't just checkbox features — they're active systems that matter during dense Orange County traffic conditions.

Nissan Altima Reliability and Ownership

The Altima has long been one of Nissan's most dependable midsize sedans, and the 2019-and-newer generation is widely regarded as an improvement over its predecessors. The 2.5-liter naturally aspirated engine in this generation replaced the turbocharged 2.0-liter used in certain trims, and owners report fewer powertrain headaches with the naturally aspirated setup.

J.D. Power gave the 2021 Altima solid marks for initial quality, and consumer ownership data shows the 2.5-liter CVT combination holds up well over time when properly maintained. At 73,693 miles, this vehicle is in its prime years — past the initial break-in period but well short of major service intervals that can add up with higher-mileage options. Regular oil changes, cabin air filter replacements, and brake fluid flushes are the primary maintenance items at this mileage, keeping ownership costs predictably low.

Used Altima buyers frequently cite the smooth, quiet ride, comfortable seats for long commutes, and consistent fuel economy as the standout ownership highlights. It's not a performance car, but it's exactly what most buyers actually need: something reliable, practical, and easy to live with.
