The 2017 Nissan Altima represents a significant evolution in the competitive mid-size sedan segment, blending refined efficiency with engaging performance. Under the hood, the standard 2.5-liter four-cylinder engine delivers a balance of power and fuel economy that appeals to daily commuters and road-trippers alike. This model year marked a continuation of Nissan’s commitment to providing a reliable powertrain that satisfies both practical needs and driving enjoyment.
Overview of the 2017 Model Year
By 2017, the Altima had established itself as a mature platform with a loyal customer base. The vehicle offered a spacious interior, advanced safety features, and a suite of available driver-assistance technologies. The engine options were designed to cater to different priorities, whether the driver sought maximum efficiency or a more assertive response. Understanding the specific engineering behind the 2017 powertrains is essential for evaluating the car’s long-term value.
Standard Engine Specifications
The heart of the 2017 Altima is its continuously variable transmission (CVT) paired with the MR20DE 2.5-liter four-cylinder engine. This unit generates 182 horsepower and 181 lb-ft of torque, providing adequate acceleration for highway merging and passing maneuvers. The compression ratio of 10.0:1 and dual intelligent variable valve timing (IVT) technology help optimize both power delivery and fuel consumption. This configuration is specifically tuned to work in harmony with the Xtronic CVT, ensuring the engine operates within its most efficient RPM range during steady-state cruising.
Performance and Efficiency Metrics
In real-world driving scenarios, the 2017 Altima achieves an EPA-estimated 28 MPG in the city and 39 MPG on the highway for the base model. This impressive efficiency is a direct result of the engine’s design and the CVT’s ability to adjust the gear ratio infinitely. Drivers can expect a driving range of approximately 400 miles on a single 13.2-gallon tank, making it a practical choice for lengthy journeys without frequent stops. The power band is linear and predictable, which contributes to a smooth and composed ride quality.
Optional Upgraded Engine
For drivers who desire more vigor, Nissan offered the SR model equipped with a more powerful engine option. The available 3.5-liter VQ35DE V6 engine produces 260 horsepower and 240 lb-ft of torque, a substantial increase over the base 4-cylinder. This V6 configuration transforms the driving dynamics, offering brisk acceleration and a robust presence on the highway. The shift from a four-cylinder to this V6 fundamentally alters the character of the Altima, prioritizing performance and presence over absolute fuel economy.
Comparative Analysis
When comparing the 2.5-liter 4-cylinder to the 3.5-liter V6, the differences are immediately apparent. The 4-cylinder setup excels in urban environments and budget-conscious ownership, while the V6 caters to those who prefer confident overtaking and a more muscular soundtrack. The V6 utilizes a conventional automatic transmission rather than the CVT found in the base models, providing a distinct gear-driven feel that enthusiasts often prefer. This trade-off between efficiency and excitement defines the dual-engine strategy for the year.
Reliability and Maintenance Considerations
Both engine options generally exhibit a solid reputation for reliability when maintained according to the factory schedule. The 2.5-liter MR20DE is known for its durability, though some owners have reported minor issues with the CVT under extreme stress. The 3.5-liter VQ35DE benefits from a long-standing reputation for robustness and longevity within the Nissan lineup. Regular oil changes, timely belt replacements, and using the recommended premium fuel for the V6 are critical for ensuring the powertrain lasts the life of the vehicle.
