The 2020 Nissan Altima is a five-passenger midsize sedan available in five trim levels: S, SR, SV, SL and Platinum. 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.
