This amount of torque provides good low-end and mid-range pull, making the Altima feel responsive and easy to drive in everyday situations. The combination of 182 horsepower and 178 lb-ft of torque gives the 2020 Altima 2.5 SL a 0-60 mph acceleration time of around 8 seconds. While this isn't sports car territory, it's certainly adequate for a mid-size sedan, and it's on par with many of its competitors. The engine's smooth and linear power delivery also contributes to a pleasant driving experience, making the Altima feel confident and controlled in a variety of conditions. So, if you're looking for a car that offers a good balance of power and efficiency, the 2020 Nissan Altima 2.5 SL is definitely worth considering.

Fuel Efficiency: How Economical is the 2020 Altima 2.5 SL?

Fuel efficiency is a major consideration for most car buyers, and the 2020 Nissan Altima 2.5 SL doesn't disappoint in this area. Thanks to its efficient engine design and continuously variable transmission (CVT), the Altima 2.5 SL achieves impressive fuel economy numbers. According to EPA estimates, the 2020 Altima 2.5 SL gets 28 mpg in the city, 39 mpg on the highway, and 32 mpg combined. These figures are quite competitive for a mid-size sedan, and they can save you a significant amount of money at the pump over the long run. The CVT plays a crucial role in maximizing fuel efficiency. Unlike traditional automatic transmissions with fixed gear ratios, a CVT can continuously adjust the gear ratio to keep the engine operating at its most efficient speed. This results in smoother acceleration and better fuel economy, especially at highway speeds. In real-world driving, the Altima 2.5 SL's fuel economy often lives up to the EPA estimates. Many drivers report achieving close to 40 mpg on the highway, making it a great choice for long road trips. Even in city driving, the Altima's fuel economy is respectable, thanks to its efficient engine and CVT. Of course, fuel economy can vary depending on driving habits and conditions. Aggressive driving, heavy traffic, and extreme weather can all negatively impact fuel economy. However, with sensible driving habits, you can expect the 2020 Altima 2.5 SL to deliver excellent fuel economy, making it a smart choice for budget-conscious drivers.

Reliability and Common Issues with the 2.5L Engine

The 2.5L engine in the 2020 Nissan Altima 2.5 SL is generally considered to be reliable, but like any engine, it's not without its potential issues. Understanding these potential problems can help you keep your Altima running smoothly for years to come. One of the most common issues reported with the 2.5L engine is related to the continuously variable transmission (CVT). Some owners have experienced CVT failures, which can be costly to repair. However, Nissan has extended the warranty on some CVT models, so it's worth checking to see if your Altima is covered. Another potential issue is related to the engine's oil consumption. Some owners have reported that their Altima consumes more oil than expected, which can lead to low oil levels and potential engine damage if not addressed. It's important to regularly check your Altima's oil level and top it off as needed. In addition to these issues, some owners have also reported problems with the engine's sensors, such as the oxygen sensor and the mass airflow sensor. These sensors can fail over time, leading to poor engine performance and reduced fuel economy. Regular maintenance, such as oil changes, filter replacements, and spark plug replacements, can help prevent many of these issues. It's also important to pay attention to any unusual noises or vibrations coming from the engine, as these could be early warning signs of a problem. Overall, the 2.5L engine in the 2020 Altima 2.5 SL is a reliable engine, but it's important to be aware of its potential issues and take steps to prevent them.
