Engine Options and Specifications

Alright, let's get straight to the nitty-gritty of the 2021 Nissan Altima SR's engine options. The SR trim, in most cases, comes with a specific engine that gives it its sporty character. In 2021, the Altima SR generally featured a 2.5-liter 4-cylinder engine. This engine is a workhorse, designed to offer a great balance of power and efficiency, which is important for daily driving. Now, let's talk numbers! This 2.5-liter engine usually delivers around 188 horsepower. That’s a good amount of power for a mid-size sedan, and it provides enough oomph for quick acceleration and confident highway merging. The torque figures are also noteworthy, contributing to the car's responsiveness. The 2021 Altima SR’s engine is paired with a continuously variable transmission (CVT). This type of transmission is designed to keep the engine operating at its most efficient speed, which helps improve fuel economy. The CVT in the Altima is generally well-regarded for its smooth operation.

One of the main advantages of the 2021 Nissan Altima SR engine is its fuel efficiency. This car is designed to be easy on the wallet, especially when it comes to fuel consumption. The exact figures can vary depending on whether you opt for front-wheel drive (FWD) or all-wheel drive (AWD). The FWD models typically offer slightly better gas mileage, but the AWD versions provide enhanced traction and stability, especially in adverse weather conditions. The combination of the 2.5-liter engine and the CVT contributes to the Altima SR's ability to achieve impressive miles per gallon. Nissan has often been praised for optimizing its engines to provide a good balance between performance and fuel economy, making the Altima SR a practical choice for everyday use. Choosing between FWD and AWD involves considering your driving needs and the kind of weather conditions you typically encounter. If you live in an area with frequent snow or ice, then AWD might be a smart choice for improved safety and control. On the other hand, if fuel efficiency is your top priority, then FWD could be the way to go. Either way, the 2021 Altima SR offers a compelling package when it comes to engine and performance.

The SR gives you the best of both worlds with its performance-oriented features and more appealing aesthetics.
