2018 Nissan Altima

The latest iteration of Nissan's popular Altima midsize sedan provides a quiet, refined interior, high-tech options and a relatively sporty driving experience. The volume-selling four-cylinder model is rated at 38 mpg on the highway, making it one of the most efficient rides in its segment.

Recent Changes

For the latest model year, Nissan has simplified the Altima's trim offerings, eliminating the base 2.5 and the 3.5 SR models.

A new Altima is expected to debut for the coming model year,


The last-generation Altima was consistently one of the best-selling cars in its class, so Nissan chose to evolve the current model with subtle, incremental improvements instead of completely starting from scratch. The wheelbase carried over unchanged, while overall length grew by an inch and width increased by 1.3 inches. The suspension features struts in front and a multi-link setup at the rear.

Despite the dearth of dimensional changes, the Altima is lighter than the last-gen model by about 80 pounds thanks to the increased use of high strength steel.

That lighter curb weight, in addition to a retuned 2.5-liter four-cylinder engine, helps the new Altima to achieve best-in-class fuel economy of 27 mpg in the city and 38 mpg on the highway. Output is rated at 182 horsepower and 180 lb-ft of torque. Also aiding on the efficiency front is a next-generation continuously variable transmission (CVT) that was re-engineered for reduced internal friction and also features new control logic and expanded gear ratio coverage.

The optional engine is a carryover 3.5-liter V6 that produces a healthy 270 horsepower and 258 lb-ft of torque. Like the four, the six-cylinder pairs exclusively with the CVT, and mileage is rated at 22/32 mpg - an increase of 1 mpg highway for the latest model year.

Premium Look Inside and Out

Nissan has further evolved the styling of the Altima with this year's refresh, giving it a look that puts it right at home next to the refreshed Sentra and Maxima sedans which also boast the "Energetic Flow” design language. While it does not go so far as to embrace the floating greenhouse look being adopted by the brand's SUVs and crossovers, it does give the Altima a modern look without sacrificing the premium elements that made the previous iteration call to mind the more premium Infiniti brand.

The cabin packs so-called "zero-gravity" seats that provide optimal support and help reduce muscular and spinal loads. Noise levels are kept to a minimum thanks to new sound-deadening materials and--for the first time--laminated front glass.

Nissan's interior refresh was intended to provide an "information-centric” experience. The center stack and console area controls were revamped allowing for better ease of use and more extensive connectivity.

All Altima models come standard with NissanConnect, a platform for Bluetooth-based smartphone integration that offers a range of apps like Facebook, Pandora radio, iHeartRadio and Online Search powered by Google.

Other available tech features include Hands-Free Text Messaging Assistant and a navigation system with SiriusXM Travel Link and real-time weather info, fuel prices, movie times and stock updates.

Trim Level Breakdown

The four-cylinder Altima sedan (2.5) is available in four trim levels: S, SV, SR and SL. Several packages are available at various trim levels.

Key Competitors

Buyers interested in the Altima should also check out the sporty Mazda Mazda6 and the stylish Chevrolet Malibu, while the feature-laden Kia Optima is also worth a look. Stalwarts of the mid-size sedan segment such as the Toyota Camry and Honda Accord also merit consideration.
