The 2017 Nissan Altima represents a significant moment in the sedan's evolution, marking a shift toward a more premium feel and advanced technology. Under the hood, the engine options were designed to balance efficiency with the sporty character the Altima had become known for. Owners and potential buyers need to understand the nuances of the powertrain to ensure proper maintenance and optimal performance from their vehicle.
Overview of Powertrain Options
For the 2017 model year, Nissan offered two distinct engine choices to cater to different driver preferences. The standard configuration paired a capable naturally aspirated engine with a smooth automatic transmission, while the higher trims featured a more robust powerplant tuned for responsiveness. This strategy allowed the Altima to compete effectively in a crowded midsize segment by providing a baseline efficient commute and an engaging performance option.
S base and SV Models
The S and SV trims were equipped with a 2.5-liter four-cylinder engine that generated 188 horsepower and 180 lb-ft of torque. This powerplant was mated to a continuously variable transmission (CVT) that prioritized fuel economy and seamless power delivery. The design of this powertrain ensured reliable daily driving, offering sufficient power for highway merging while maintaining respectable fuel efficiency figures that appealed to budget-conscious consumers.
SR and SL Models
Upgrading to the SR and SL models introduced the 3.5-liter V6 engine, a significant step up in performance. This unit produced 271 horsepower and 244 lb-ft of torque, providing a noticeable increase in acceleration and passing confidence. The V6 configuration was paired with a six-speed automatic transmission, delivering a more connected driving experience with paddle shifters available on the steering wheel for manual gear selection.
Engineering and Technology
Nissan incorporated several advanced technologies to enhance the efficiency and performance of the 2017 Altima’s engines. The VC-Turbo technology was not present in this year’s model, but the variable valve timing system played a crucial role. This system optimizes airflow into the cylinders, improving combustion efficiency and power output across the rev range while also helping to reduce emissions.
Fuel Economy and Efficiency
Fuel economy remains a critical factor for sedan buyers, and the 2017 Altima delivered competitive numbers. The base 2.5-liter engine achieved an EPA-estimated 28 city / 39 highway MPG, making it an economical choice for daily commutes. The V6 engine, while more powerful, managed a respectable 22 city / 30 highway MPG, balancing performance with reasonable running costs for many drivers.
Reliability and Maintenance
Both engine options generally demonstrated solid reliability, contributing to the Altima's reputation as a dependable family car. Regular oil changes, using the manufacturer-recommended viscosity, are essential for the longevity of the 2.5-liter engine. The V6 requires more diligent attention to cooling system maintenance and transmission fluid checks to ensure the powertrain operates within optimal temperature ranges under stress.
Common Issues and Considerations
While largely reliable, owners have reported specific issues related to the 2017 models. Some 3.5-liter V6 engines experienced timing chain tensioner failures, which could lead to unusual noises or, in severe cases, engine damage if not addressed. Additionally, the CVT in the four-cylinder models sometimes exhibited harsh engagement or overheating warnings, particularly in warmer climates or during aggressive driving cycles.
Verdict for Enthusiasts
Choosing between the engine options depends heavily on the driver's priorities. The 2.5-liter provides excellent value and efficiency for practical use, while the 3.5-liter V6 satisfies the need for spirited performance and a more premium feel. Understanding the characteristics of the 2017 Nissan Altima engine lineup ensures that buyers can select the trim that best aligns with their driving habits and long-term ownership expectations.
