Used 2020 Nissan Altima Sedan Trims Comparison

The Altima's standard engine is a 2.5-liter four-cylinder (188 horsepower, 180 lb-ft of torque) paired with a continuously variable automatic transmission (CVT). Front-wheel drive is standard, and all-wheel drive is optional.

An optional turbocharged 2.0-liter four-cylinder (248 hp, 280 lb-ft) is available for SR and Platinum trims only. It's also paired with a CVT automatic, but it's limited to front-wheel drive.

The S base trim is indeed pretty basic, but it offers decent features for the money, such as a power-adjustable driver's seat, a 60/40-split folding rear seat, a rearview camera, push-button start, and an infotainment system with an 8-inch touchscreen, two USB inputs, Bluetooth phone and audio streaming, and Apple CarPlay and Android Auto smartphone connections.

The S comes with front collision warning, automatic emergency braking and a rearview camera. And for 2020 you can append additional safety features including blind-spot monitoring, lane departure warning and rear parking sensors.

The SR is the Altima's "sport" trim, offering a sportier suspension, transmission paddle shifters and unique styling elements. It also comes with the driver assistance features that are optional on the S trim. The SR can also be ordered with a sunroof and heated seats.

The SV blends features from the S and the SR (minus the SR's sportier elements, primarily suspension and styling) and adds items such as noise-reducing side windows, heated front seats and dual-zone climate control. Nissan's ProPilot Assist technology — largely stop-and-go adaptive cruise control and lane keeping assist — is also included.

Moving up to the SL brings leather seating, a navigation system and a nine-speaker Bose audio system. Springing for the Platinum adds finishing touches such as 19-inch wheels, a 360-degree camera and ambient cabin lighting.
