The 2017 Nissan Sentra represents a pivotal moment for the compact sedan, blending improved efficiency with a more engaging driving dynamics package. Under the hood, buyers found a choice between a capable naturally aspirated engine and a surprisingly robust turbocharged option, catering to both economy-focused commuters and drivers seeking a bit more pep. This model year marked the Sentra's evolution into a more refined competitor, with powertrains that emphasized real-world performance and long-term reliability.
Overview of the 2017 Model Year
For the 2017 model year, the Nissan Sentra arrived with a significant update that moved it beyond its reputation as a basic commuter car. The exterior design was sharpened, featuring a more aggressive front grille and sculpted lines that gave it a sportier stance. Inside, the cabin benefited from higher quality materials and a more intuitive infotainment system. This focus on refinement extended directly to the mechanicals, where Nissan offered powertrains designed to balance efficiency, power, and durability for a diverse range of drivers.
The Standard SR Engine: Efficiency and Adequacy
The workhorse of the 2017 Sentra lineup was the 2.0-liter MR20DE four-cylinder engine, found in the base S and mid-level SV trims. This naturally aspirated unit was a proven design, known for its smooth operation and frugal nature. While not a performance monster, it delivered the 130 horsepower and 139 lb-ft of torque necessary for relaxed highway merging and daily city driving. Its primary virtue was efficiency, helping the Sentra achieve competitive fuel economy figures that made it a practical choice for budget-conscious buyers.
Performance and Efficiency of the MR20DE
Delivers a balanced mix of fuel economy and adequate power for everyday needs.
Features low friction internals and an optimized combustion process.
Provides smooth power delivery ideal for stop-and-go traffic.
Contributes to the Sentra's class-leading EPA estimated MPG ratings.
The Turbo Option: S and SR Turbo Trims
For drivers who desired more than just efficient transportation, the 2017 Sentra offered the turbocharged SR Turbo model. This trim was equipped with a 1.8-liter turbocharged HR18DETT engine, a unit that generated an impressive 188 horsepower and 180 lb-ft of torque. This power output represented a significant jump over the standard engine, providing brisk acceleration and confident passing power. The turbocharged Sentra transformed the driving experience, making it feel closer to a sports sedan than its compact segment rivals.
Engineering the Turbocharged HR18DETT
Nissan's 1.8-liter turbo engine was a sophisticated piece of machinery that utilized a small, efficient turbocharger to force more air into the combustion chamber. This design allowed the smaller displacement engine to punch well above its weight class. The result was a power curve that delivered strong mid-range torque, the sweet spot for most driving scenarios. When paired with the available CVT, the turbo Sentra offered a responsive and connected feel that belied its compact status.
Drivetrain and Transmission Choices
Power from both the MR20DE and HR18DETT engines was sent to the front wheels via a continuously variable transmission (CVT). While CVTs can sometimes feel disconnected or produce a rubberband-like engine note under heavy throttle, Nissan's implementation in the Sentra was tuned for smoothness and efficiency. The CVT played a crucial role in maximizing the turbo engine's performance by keeping it in its optimal power band. For the 2017 model, all Sentras came standard with a refined CVT that prioritized comfort and fuel savings.
