Engine Options and Horsepower

The 2017 Nissan Altima SR primarily comes with two engine choices, each offering a different blend of fuel efficiency and power. Understanding these options is crucial for appreciating what the Altima SR brings to the table. Let's explore each one in detail.

2.5-Liter Inline-4 Engine

The base engine for the 2017 Altima SR is a 2.5-liter inline-4. This engine is designed to provide a balance between fuel economy and adequate power for daily driving. It's the go-to choice for those who prioritize efficiency without sacrificing too much in terms of performance.

Horsepower: This engine churns out around 179 horsepower. While it might not sound like a massive number, it's more than sufficient for navigating city streets and cruising on the highway. The engine is tuned to deliver power smoothly across the RPM range, making it feel responsive in various driving conditions.

Performance: The 2.5-liter engine provides a decent amount of torque, which helps with acceleration and passing maneuvers. It's paired with Nissan's Xtronic CVT (Continuously Variable Transmission), which further enhances fuel efficiency by keeping the engine in its optimal power band. The combination results in a driving experience that's both comfortable and economical.

Fuel Economy: One of the key advantages of this engine is its fuel economy. It typically achieves around 27 mpg in the city and 38 mpg on the highway. These figures make the Altima SR a practical choice for commuters and anyone who values saving money at the pump. The engine’s design focuses on minimizing friction and maximizing combustion efficiency, contributing to its impressive mileage.

Driving Experience: The driving experience with the 2.5-liter engine is smooth and predictable. The CVT transmission ensures seamless acceleration, and the engine noise is kept to a minimum. While it may not provide the thrilling acceleration of a sports car, it offers a refined and composed ride that's perfect for everyday use. The Altima SR's suspension is tuned to provide a comfortable yet controlled ride, making it a pleasant experience even on rough roads.

3.5-Liter V6 Engine

For those craving more power, the 2017 Altima SR also offers an optional 3.5-liter V6 engine. This engine transforms the car into a significantly more spirited performer, providing a noticeable boost in acceleration and overall driving excitement. If you're someone who enjoys having extra power on tap, this is the engine to go for.

Horsepower: The 3.5-liter V6 engine delivers an impressive 270 horsepower. This substantial increase in power over the base engine makes the Altima SR feel much more dynamic and responsive. The engine is designed to provide strong acceleration and ample power for overtaking other vehicles.

Performance: With 270 horsepower, the Altima SR can accelerate from 0 to 60 mph in around 6 seconds. This is a significant improvement over the 2.5-liter engine, making the car feel much quicker and more engaging to drive. The V6 engine provides a broader powerband, meaning that it delivers strong performance across a wider range of RPMs.

Fuel Economy: While the V6 engine offers significantly more power, it does come at the expense of fuel economy. Expect to get around 22 mpg in the city and 32 mpg on the highway. While these numbers are still respectable, they're not as impressive as the 2.5-liter engine. However, many drivers find the trade-off worth it for the added performance.

Driving Experience: The driving experience with the 3.5-liter V6 engine is significantly more exhilarating. The engine provides strong acceleration and a satisfying exhaust note. The Altima SR's suspension is tuned to handle the extra power, providing a balanced and controlled ride. The steering is precise and responsive, making the car feel confident and planted on the road. The V6 engine transforms the Altima SR from a comfortable sedan into a genuinely fun-to-drive machine.

SR Specific Features Enhancing Performance

Beyond just the engine options, the 2017 Nissan Altima SR includes several features designed to enhance its overall performance and sporty appeal. These features contribute to a more engaging and dynamic driving experience.

Sport-Tuned Suspension

The SR model comes with a sport-tuned suspension that provides a firmer and more controlled ride. This suspension setup reduces body roll in corners and improves overall handling. It makes the car feel more responsive and connected to the road, enhancing the driving experience for those who enjoy spirited driving.

Handling: The sport-tuned suspension significantly improves the Altima SR's handling capabilities. It allows the car to corner more confidently and maintain its composure on winding roads. The firmer suspension provides better feedback to the driver, making it easier to anticipate and react to changes in road conditions.

Ride Comfort: While the sport-tuned suspension does provide better handling, it does come at a slight cost to ride comfort. The ride may feel a bit firmer than the standard Altima, but it's still comfortable enough for daily driving. The trade-off is well worth it for those who prioritize handling and sporty driving dynamics.

Paddle Shifters

The Altima SR includes paddle shifters mounted on the steering wheel, allowing drivers to manually control the CVT transmission. This feature provides a more engaging and interactive driving experience, especially when paired with the V6 engine. Paddle shifters give the driver more control over gear selection and engine RPM, allowing for quicker acceleration and more precise handling.

Control: Paddle shifters give the driver more control over the car's performance. They allow for quick and easy gear changes, making it easier to accelerate and decelerate. This is particularly useful when driving on winding roads or when needing to pass other vehicles.

Engagement: Using paddle shifters can make driving more engaging and enjoyable. They allow the driver to feel more connected to the car and more in control of its performance. This can be especially appealing to those who enjoy sporty driving and want a more interactive experience.

Unique Styling Cues

The Altima SR also features several unique styling cues that set it apart from other Altima models. These include a rear spoiler, sporty wheels, and unique interior trim. These features enhance the car's sporty appearance and give it a more aggressive and stylish look.

Exterior: The rear spoiler and sporty wheels give the Altima SR a more athletic and dynamic appearance. These features make the car stand out from the crowd and give it a more premium and upscale look.

Interior: The unique interior trim adds a touch of sportiness to the cabin. This can include features like sport seats, carbon-fiber accents, and aluminum pedals. These details enhance the driving experience and make the car feel more special.
