The 2020 Nissan Altima SR is a popular mid-size sedan known for its sleek design, comfortable ride, and fuel-efficient engine options. If you're curious about what powers this sporty trim level, you've come to the right place. Let's dive into the engine specs and performance characteristics of the 2020 Altima SR.

Engine Options for the 2020 Altima SR

The 2020 Nissan Altima SR offers two engine choices, each providing a different balance of power and efficiency. Understanding these options is crucial when considering this vehicle.

Standard Engine: 2.5-Liter DOHC 4-Cylinder

The base engine for the 2020 Altima SR is a 2.5-liter DOHC 4-cylinder engine. This engine is designed to provide a smooth and efficient driving experience for daily commutes and longer trips. Let's look at the detailed specifications:

• Configuration: Inline 4-cylinder
• Displacement: 2.5 liters (2488 cc)
• Valvetrain: DOHC (Dual Overhead Camshaft) with four valves per cylinder
• Horsepower: 182 hp at 6,000 rpm
• Torque: 178 lb-ft at 4,000 rpm
• Fuel System: Multi-point fuel injection
• Fuel Economy: EPA-estimated 28 mpg city / 39 mpg highway / 32 mpg combined (for FWD models). Note that fuel economy can vary based on driving conditions and habits.

This engine is paired with Nissan's Xtronic CVT (Continuously Variable Transmission), which helps to maximize fuel efficiency and provide seamless acceleration. The CVT offers a wide gear ratio, allowing the engine to operate at its most efficient speed.

Performance and Driving Experience: The 2.5-liter engine provides adequate power for most driving situations. It offers a good balance between fuel economy and performance, making it a practical choice for everyday use. The engine is responsive and provides sufficient acceleration for merging onto highways and navigating city streets. The Xtronic CVT contributes to a smooth and comfortable ride, with simulated gear changes that mimic a traditional automatic transmission.

Optional Engine: 2.0-Liter VC-Turbo 4-Cylinder

For those seeking more power and a sportier driving experience, the 2020 Altima SR offers an optional 2.0-liter VC-Turbo 4-cylinder engine. This engine is a technological marvel, featuring variable compression technology that adjusts the compression ratio based on driving conditions. This innovative design allows the engine to optimize power and efficiency.

• Configuration: Inline 4-cylinder
• Displacement: 2.0 liters (1997 cc)
• Valvetrain: DOHC (Dual Overhead Camshaft) with four valves per cylinder
• Horsepower: 248 hp at 5,600 rpm (when using premium fuel)
• Torque: 273 lb-ft at 4,000 rpm
• Fuel System: Direct fuel injection
• Fuel Economy: EPA-estimated 25 mpg city / 34 mpg highway / 29 mpg combined (for FWD models). Note that fuel economy can vary based on driving conditions and habits.

Like the base engine, the VC-Turbo engine is also paired with Nissan's Xtronic CVT. However, the CVT is tuned to handle the increased power and torque output of the turbocharged engine.

Performance and Driving Experience: The 2.0-liter VC-Turbo engine transforms the Altima SR into a more engaging and exciting vehicle to drive. The increased horsepower and torque provide significantly improved acceleration and responsiveness. The engine feels strong and confident in all driving situations, whether you're passing on the highway or navigating twisty roads. The variable compression technology ensures that the engine is always operating at its optimal efficiency, providing a balance of power and fuel economy. The Xtronic CVT works seamlessly with the VC-Turbo engine, delivering smooth and quick shifts.

Key Differences Between the Two Engines

To summarize, here's a table highlighting the key differences between the two engine options for the 2020 Altima SR:

Drivetrain and Transmission

Both engine options for the 2020 Nissan Altima SR come standard with a front-wheel-drive (FWD) drivetrain. While all-wheel-drive (AWD) is available on some other Altima trims, it is not an option for the SR model. As mentioned earlier, both engines are paired with Nissan's Xtronic CVT (Continuously Variable Transmission).

Xtronic CVT (Continuously Variable Transmission)

The Xtronic CVT is designed to provide smooth and efficient performance. Unlike traditional automatic transmissions with fixed gear ratios, the CVT uses a system of pulleys and belts to offer a virtually infinite range of gear ratios. This allows the engine to operate at its most efficient speed, maximizing fuel economy and providing seamless acceleration. The CVT also features simulated gear changes that mimic a traditional automatic transmission, giving the driver a more familiar and engaging driving experience.

Performance and Handling

The 2020 Nissan Altima SR is designed to offer a balance of comfort and sporty handling. The SR trim level includes several features that enhance its performance and driving dynamics.

Sport-Tuned Suspension

The Altima SR features a sport-tuned suspension that provides a firmer and more controlled ride. The suspension is designed to reduce body roll and improve handling, making the car feel more responsive and engaging to drive. The sport-tuned suspension enhances the overall driving experience, giving the Altima SR a more athletic feel.

Steering and Handling

The steering in the Altima SR is precise and responsive, providing good feedback to the driver. The car feels well-balanced and easy to control, making it a pleasure to drive on both city streets and winding roads. The combination of the sport-tuned suspension and responsive steering contributes to a confident and enjoyable driving experience.

Fuel Efficiency

Fuel efficiency is an important consideration for many car buyers, and the 2020 Nissan Altima SR offers competitive fuel economy ratings. As mentioned earlier, the EPA-estimated fuel economy for the 2.5-liter engine is 28 mpg city / 39 mpg highway / 32 mpg combined, while the 2.0-liter VC-Turbo engine is rated at 25 mpg city / 34 mpg highway / 29 mpg combined. Keep in mind that actual fuel economy may vary depending on driving conditions, habits, and maintenance.

Factors Affecting Fuel Efficiency

Several factors can affect the fuel efficiency of your 2020 Altima SR, including:

• Driving Habits: Aggressive driving, such as rapid acceleration and hard braking, can significantly reduce fuel economy.
• Driving Conditions: Stop-and-go traffic, hilly terrain, and extreme weather conditions can also negatively impact fuel efficiency.
• Maintenance: Regular maintenance, such as oil changes and tire rotations, can help to maintain optimal fuel efficiency.
• Tire Pressure: Properly inflated tires can improve fuel economy, while underinflated tires can reduce it.
• Cargo and Passengers: Carrying heavy loads or passengers can also decrease fuel efficiency.

Conclusion

The 2020 Nissan Altima SR offers a choice of two engines: a 2.5-liter 4-cylinder for a balance of efficiency and adequate power, and a 2.0-liter VC-Turbo 4-cylinder for those seeking a more thrilling driving experience. Both engines are paired with a smooth and efficient Xtronic CVT. With its sport-tuned suspension and responsive steering, the Altima SR provides a comfortable and engaging ride. Whether you prioritize fuel economy or performance, the 2020 Altima SR has an engine option to suit your needs. Consider your driving style and preferences when choosing between the two engines to ensure you get the most out of your Altima SR.
