The 2018 Nissan Altima represents a pivotal moment in the sedan's evolution, blending refined efficiency with engaging performance. This model year marked the introduction of a standard turbocharged engine, transforming the driving dynamics of a vehicle previously known for its competent but unexciting nature. Buyers found a compelling alternative to the mainstream options, thanks to its blend of modern technology, comfortable interior, and responsive handling.
Engine Options and Performance
Under the hood, the 2018 Altima offered a clear choice between two distinct powertrains, catering to different priorities. The base S and SV trims came equipped with a naturally aspirated 2.5-liter four-cylinder engine, producing 188 horsepower. This setup provided adequate power for daily commuting and highway merging, paired with a smooth continuously variable transmission that prioritized fuel economy.
Turbocharged Efficiency and Power
The headline feature for 2018 was the available turbocharged 2.0-liter four-cylinder engine, which became the standard powertrain for the SV and higher trims. This unit generates 200 horsepower and 191 lb-ft of torque, offering a noticeable improvement in acceleration and passing power. The turbocharged model strikes an ideal balance between efficiency and performance, delivering a spirited drive without sacrificing daily usability.
Fuel Economy and Engineering
Nissan's engineering efforts extended beyond raw power, focusing heavily on efficiency across the lineup. The naturally aspirated model achieved an EPA-estimated 28 MPG in the city and 39 MPG on the highway. The turbocharged variant, while more powerful, managed an impressive 32 MPG in the city and 40 MPG on the highway, making it a practical choice for long-distance drivers seeking both performance and economy.
Interior Comfort and Technology
The cabin of the 2018 Altima was designed to be a quiet sanctuary, utilizing extensive sound insulation and acoustic glass to minimize road and wind noise. Seats were bolstered for better support during spirited drives, yet remained plush enough for comfortable long-distance travel. The dashboard layout was intuitive, placing essential controls within easy reach of the driver.
Infotainment and Connectivity
A significant upgrade was the available 7-inch touchscreen infotainment system, featuring Apple CarPlay and Android Auto integration. This move brought the Altima in line with modern connectivity standards, allowing seamless use of smartphone apps for navigation, music, and calls. The inclusion of a Bose audio system in higher trims further enhanced the in-car experience, delivering clear and rich sound quality. Safety Features and Reliability Safety was a core consideration, with the 2018 model receiving a Top Safety Pick+ rating from the Insurance Institute for Highway Safety (IIHS). Standard safety suite, known as Nissan Safety Shield 360, included automatic emergency braking with pedestrian detection, rear automatic braking, and lane departure warning. These features provided a robust layer of protection for occupants in various driving scenarios.

Design and Practicality
Externally, the 2018 Altima adopted a more aggressive and athletic stance compared to its predecessor, with a lower grille and sharper LED headlights. This design language signaled its performance intent while maintaining the brand's signature elegance. The trunk offered generous space, easily accommodating groceries, luggage, or sports equipment, making the sedan a practical choice for everyday life.
