About This 2021 Nissan Altima 2.5 SV

The 2021 model year represents a mature and refined generation of the Altima, which was fully redesigned in 2019. This particular example sits in the SV trim — a sweet spot that steps up meaningfully from the base S while keeping pricing approachable. At just under 74,000 miles, this Altima is comfortably within the range where most drivers will experience years of reliable, low-drama ownership. The Silver exterior gives it a clean, professional look that holds up well in Southern California sunshine.

Whether you're commuting along the I-15 corridor, running errands through Escondido's neighborhoods, or heading out toward the coast, this Altima is the kind of car that just works — every single day.

2021 Nissan Altima Performance and Engine

Under the hood, the 2021 Altima 2.5 SV is powered by a naturally aspirated 2.5-liter four-cylinder engine producing around 188 horsepower. Paired with Nissan's Xtronic CVT automatic transmission and front-wheel drive, this setup is tuned for smooth, confident acceleration rather than sport — which is exactly what most Altima buyers want.

The Xtronic CVT is one of the better-regarded continuously variable transmissions in the segment, delivering seamless power delivery that keeps engine revs low during cruising. That translates directly to real-world fuel efficiency, with EPA estimates in the range of 28 MPG city and 39 MPG highway — a significant advantage if you're covering long stretches of the 78 or heading up to Temecula regularly.

Nissan Altima 2.5 SV Features and Interior

The SV trim builds on the base Altima with a genuinely useful package of comfort and convenience upgrades. Expect features including an 8-inch touchscreen infotainment display with Apple CarPlay and Android Auto compatibility, a heated steering wheel, heated front seats, dual-zone automatic climate control, and remote start — all factory standard on this trim level.

The Altima's interior is roomy by midsize sedan standards. Rear passengers in particular benefit from class-competitive legroom, making this a comfortable four-person car rather than just a driver-focused commuter. Soft-touch materials and thoughtful storage placement give the cabin a quality feel that punches above the price point.

Nissan Altima Reliability and Ownership

The 2021 Nissan Altima has a solid reliability record. Nissan's KR25DE 2.5-liter engine is a well-proven unit, and the 2019-and-later generation Altima eliminated many of the concerns that followed older models. The Xtronic CVT, while sometimes criticized in older Nissans, received improvements in this generation and performs reliably with proper fluid maintenance.

Owners consistently praise the Altima for low running costs, affordable parts availability, and an overall ownership experience that doesn't demand much attention. J.D. Power gave the 2021 Altima strong marks in initial quality, and it earned respectable scores from the IIHS in safety testing. For a used midsize sedan at this price point, the Altima is one of the most sensible choices on the market.
