Hey guys! Ever wondered about the horsepower of the 2017 Nissan Altima SR? Or maybe you're curious about its overall performance? Well, you've landed in the right spot! Let's dive deep into what makes the 2017 Altima SR a fantastic ride, focusing on its engine power and performance capabilities. Whether you're a car enthusiast, a potential buyer, or just doing some research, this article has got you covered.

Engine and Horsepower

Let's get straight to the point: The 2017 Nissan Altima SR primarily comes with a 2.5-liter four-cylinder engine. This engine is designed to deliver a balance of fuel efficiency and adequate power for daily driving. So, how much horsepower does this engine pack? The 2.5-liter engine produces around 179 horsepower at 6,000 rpm. That's a pretty decent number for a mid-size sedan, offering enough oomph for your daily commute and occasional highway cruising.

But wait, there's more! Some trims of the 2017 Altima, including potentially the SR, could be equipped with an optional 3.5-liter V6 engine. If you happen to get your hands on an Altima SR with this V6, you're in for a treat. This engine bumps the horsepower up to around 270 hp, providing a significantly more thrilling driving experience. Imagine the surge of power as you accelerate – it’s a completely different beast compared to the four-cylinder version!

Digging Deeper into the Engine Specs

To truly appreciate the horsepower and performance of the 2017 Nissan Altima SR, it's essential to understand the engine specifications in detail. The standard 2.5-liter DOHC 16-valve four-cylinder engine isn't just about horsepower; it also delivers a respectable 177 lb-ft of torque at 4,000 rpm. This torque figure is crucial because it dictates how quickly the car can accelerate from a standstill or at lower speeds. The combination of horsepower and torque ensures a responsive and enjoyable driving experience.

The engine features a Continuously Variable Valve Timing Control System (CVTCS) on intake and exhaust valves, optimizing engine performance and efficiency across various driving conditions. This technology helps the engine deliver power smoothly and efficiently, contributing to better fuel economy without sacrificing performance. The engine's design also incorporates features to reduce friction and improve overall durability, ensuring it remains reliable for years to come.

For those fortunate enough to experience the 3.5-liter V6 engine, the numbers are even more impressive. This engine churns out approximately 270 horsepower and 251 lb-ft of torque. The increased power transforms the Altima SR into a genuinely quick sedan, capable of accelerating from 0 to 60 mph in around six seconds. The V6 engine also benefits from advanced technologies that enhance its performance and efficiency, making it a compelling option for drivers who crave more power.

Whether you opt for the 2.5-liter four-cylinder or the 3.5-liter V6, the 2017 Nissan Altima SR offers a well-engineered engine that balances power, efficiency, and reliability. Understanding these engine specs helps you appreciate the engineering that goes into delivering a satisfying driving experience.

Performance and Handling

Okay, so we know the horsepower figures, but what about the actual driving experience? The 2017 Nissan Altima SR isn't just about straight-line speed; it's also about how it handles on the road. The SR trim typically comes with a sport-tuned suspension, which means it's designed to offer a slightly firmer and more controlled ride compared to the base models. This enhanced suspension reduces body roll in corners, giving you more confidence when tackling winding roads. The steering is also tuned to be more responsive, providing better feedback from the road.

Transmission and Drivetrain

Most 2017 Nissan Altima SR models come with a Continuously Variable Transmission (CVT). Now, CVTs sometimes get a bad rap, but Nissan has done a pretty good job of tuning theirs. It mimics the behavior of a traditional automatic transmission, providing smooth and seamless acceleration. While it might not offer the same level of engagement as a manual, the CVT helps to maximize fuel efficiency without sacrificing too much in terms of performance. The Altima SR is a front-wheel-drive car, which is typical for this class of vehicle. Front-wheel drive offers good traction in most conditions and helps to keep production costs down.

Real-World Performance

In real-world driving conditions, the 2017 Nissan Altima SR performs admirably. The 2.5-liter engine provides adequate acceleration for merging onto highways and overtaking other cars. The sport-tuned suspension keeps the car planted and stable, even on less-than-perfect road surfaces. If you opt for the V6, you'll experience a noticeable improvement in acceleration and overall responsiveness. The V6-powered Altima SR feels genuinely quick, making it a fun car to drive.

The Altima SR also offers good visibility, thanks to its well-designed windows and mirrors. The seats are comfortable and supportive, making it a great car for long road trips. The interior is well-laid-out, with all the controls within easy reach. Overall, the 2017 Nissan Altima SR is a well-rounded sedan that offers a good balance of performance, comfort, and practicality.

Fuel Efficiency

Let's be real, horsepower is awesome, but we also need to consider fuel efficiency, right? The 2017 Nissan Altima SR strikes a decent balance between power and economy. With the 2.5-liter engine, you can expect to get around 27 mpg in the city and 38 mpg on the highway. These numbers are pretty competitive for a mid-size sedan, making it a good choice for daily commuting.

If you go for the V6 engine, the fuel economy will take a bit of a hit, but it's not as drastic as you might think. You can expect around 22 mpg in the city and 32 mpg on the highway with the V6. While it's not as frugal as the four-cylinder, the extra horsepower might be worth the trade-off for some drivers.

Factors Affecting Fuel Economy

Several factors can affect the fuel economy of your 2017 Nissan Altima SR. Your driving style is a big one. If you have a heavy foot and like to accelerate quickly, you'll likely see lower fuel economy numbers. Regular maintenance, such as keeping your tires properly inflated and changing your oil on time, can also help to improve fuel efficiency. Additionally, the weight you carry in your car can impact fuel economy. The less weight you're hauling around, the better your fuel economy will be.

Tips for Improving Fuel Economy

If you're looking to squeeze every last mile out of each gallon, here are a few tips: Drive smoothly and avoid sudden acceleration or braking. Use cruise control on the highway to maintain a consistent speed. Combine errands into one trip to reduce the number of cold starts. And finally, make sure your car is properly maintained. By following these tips, you can maximize the fuel economy of your 2017 Nissan Altima SR and save money at the pump.
