Engine and Horsepower

The 2017 Nissan Altima SR primarily features a 2.5-liter four-cylinder engine. This engine is designed to provide a balance of power and fuel efficiency, making it a practical choice for daily driving. The 2.5-liter engine delivers approximately 179 horsepower at 6,000 rpm and 177 lb-ft of torque at 4,000 rpm. This level of power is more than adequate for city commuting and highway cruising.

For those seeking even more power, some trims of the 2017 Altima offer an optional 3.5-liter V6 engine. However, the SR trim typically comes standard with the 2.5-liter engine, focusing on a sporty driving experience without sacrificing fuel economy.

Performance Metrics

Understanding the horsepower is just one aspect of the Altima SR's performance. Torque, which measures the engine's rotational force, is equally important. The 177 lb-ft of torque ensures that the Altima SR has sufficient pulling power, whether you're accelerating from a stop or overtaking on the highway.

The engine is paired with Nissan's Xtronic CVT (Continuously Variable Transmission). This transmission is engineered to provide smooth and seamless gear transitions, optimizing fuel efficiency while maintaining a responsive feel. The CVT helps the Altima SR achieve impressive fuel economy figures, making it an economical choice for daily use.

Driving Experience

The SR trim of the 2017 Altima is designed to offer a sportier driving experience compared to the base models. It typically includes features such as a sport-tuned suspension, which enhances handling and reduces body roll during cornering. The SR also often comes with paddle shifters, allowing drivers to manually control gear changes for a more engaging experience.

The combination of the 179 horsepower engine, sport-tuned suspension, and paddle shifters contributes to a driving experience that is both enjoyable and practical. The Altima SR feels planted and confident on the road, making it a great choice for drivers who appreciate a bit of sportiness in their daily commute.

Additional Features Enhancing Performance

Beyond the engine and transmission, several other features contribute to the overall performance and driving experience of the 2017 Nissan Altima SR.

Sport-Tuned Suspension

The sport-tuned suspension is a key element that sets the SR trim apart from other Altima models. This suspension system is designed to provide a firmer and more controlled ride. By reducing body roll and improving responsiveness, the sport-tuned suspension enhances the Altima SR's handling capabilities.

Paddle Shifters

Paddle shifters, usually mounted on the steering wheel, allow the driver to manually shift gears without using a traditional gear lever. This feature gives drivers more control over the engine's power and torque, enhancing the sporty feel of the Altima SR. Whether you're navigating winding roads or simply want a more engaging driving experience, paddle shifters add an extra layer of control.

Enhanced Steering

The 2017 Altima SR often includes an enhanced steering system that provides more precise and responsive feedback. This helps the driver feel more connected to the road and makes it easier to maneuver the vehicle in various driving conditions. The enhanced steering complements the sport-tuned suspension, contributing to a more confident and enjoyable driving experience.
