2023 Nissan Altima Performance and Engine

A Capable 2.5-Liter Four-Cylinder with AWD Confidence

Under the hood sits Nissan's proven 2.5-liter four-cylinder engine, producing around 182 horsepower and 178 lb-ft of torque. Paired with Nissan's Xtronic CVT automatic transmission, power delivery is seamless and smooth — no harsh gear shifts, just a linear, responsive acceleration that's equally at home in stop-and-go traffic on Highway 78 and open freeway cruising. What makes this particular Altima stand out is the all-wheel drive system — a feature that's genuinely uncommon in the mid-size sedan segment. Nissan's AWD setup continuously monitors road conditions and distributes torque front to rear in real time, giving you added traction and stability on wet San Diego County roads during winter rain season or on winding canyon roads throughout the region.

Nissan Altima SL Features and Interior

The Premium Trim That Has It All

The 2.5 SL is Nissan's flagship Altima trim, and it shows. Expect premium heated and ventilated leather seats, a heated steering wheel, Bose premium audio system, wireless Apple CarPlay and Android Auto, a large 8-inch touchscreen display, dual-zone automatic climate control, and a suite of ProPilot Assist driver assistance technologies. The SL also includes Nissan's Zero Gravity front seats — inspired by NASA research — which are genuinely among the most comfortable seats in the class on long drives. Remote start, a panoramic moonroof, and Nissan Intelligent Around View Monitor (360-degree camera system) round out a feature list that rivals vehicles costing significantly more.

Nissan Altima Reliability and Ownership

What Owners and Experts Say

The Nissan Altima has a long track record of dependability, and the 2023 model continues that legacy. J.D. Power has consistently rated the Altima highly for initial quality, and the QR25DE-based 2.5-liter engine is one of Nissan's most field-proven powerplants. Owners regularly report low maintenance costs and strong fuel economy — expect around 26 MPG city and 36 MPG highway on the FWD variant, with the AWD model returning slightly less but still highly competitive at around 25/34 MPG. At 51,155 miles, this car is well within its prime service life, with routine maintenance like oil changes and tire rotations being the primary concerns at this mileage. The CVT transmission, while sometimes debated among enthusiasts, has proven reliable in real-world Altima ownership when serviced correctly.
