The 2021 Nissan Sentra SR builds on the Sentra’s redesign with a sport‑focused appearance and upgraded equipment, offering a sharper driving feel and a more premium cabin than lower trims. Powered by a 2.0‑liter four‑cylinder engine paired with a CVT, the SR delivers smooth, efficient daily performance with responsive handling; however, wider SR‑specific tires can make the ride slightly firmer compared to other trims. The SR trim adds signature exterior upgrades such as LED headlights, sport‑styled bodywork, and unique wheel designs, while the interior benefits from sport cloth seating, Apple CarPlay and Android Auto, intuitive climate controls, and available comfort options like heated seats. Safety is a major strength: the Sentra SR includes Nissan’s Safety Shield 360, featuring automatic emergency braking with pedestrian detection, blind‑spot warning, rear cross‑traffic alert, lane‑departure warning, rear automatic braking, and a rearview camera. Overall, the Sentra SR combines sporty styling, modern tech, and top‑tier safety engineering, making it a confident and value‑focused compact sedan.
