Room to Stretch Out

The Sonata boasts a total passenger volume of 104.4 cubic feet, outclassing the Altima’s 100.8 cubic feet. This translates to more headroom, legroom, and shoulder room for both front and rear passengers—making long trips more comfortable for everyone.

With 16.0 cubic feet of cargo space, the Sonata’s trunk is one of the largest in its class. The Altima offers just 15.4 cubic feet, which can make a difference when loading luggage, groceries, or sports gear.  

Premium Materials and Quiet Ride  

Establishing a premium atmosphere, the Sonata features available quilted leather upholstery, soft-touch surfaces, and ambient lighting. This near-luxury cabin comes at a mainstream price, making it a major reason that drivers chose the Sonata. Kelley Blue Book calls this ride “a superb sedan.”  

Meanwhile, the Altima’s materials are decent but less refined, with more hard plastics and fewer upscale touches.  

Hyundai’s attention to sound insulation means the Sonata’s cabin remains quieter at highway speeds, enhancing comfort and conversation.  

Technology and Infotainment

Screens and Connectivity

The Sonata leads with a standard 12.3-inch digital instrument cluster and an available 12.3-inch touchscreen infotainment system—both larger and more advanced than the Altima’s 7-inch instrument display and 12.3-inch touchscreen. 

Wireless Apple CarPlay and Android Auto are standard on the Sonata, while the Altima only offers these features with a wired connection on most trims. 

Reviewers consistently praise the Sonata’s intuitive infotainment interface, responsive touchscreen, and physical controls for climate and audio. The Altima’s system is functional but less polished, with some dated graphics and smaller screen options on lower trims.  

Convenience Features  

As part of its upscale attitude, the Sonata offers available features such as a panoramic sunroof, ventilated front seats, heated rear seats, and a premium Bose audio system. The Altima doesn’t have ventilated seats on the menu -- a big disappointment for Phoenix travelers -- and only offers heated rear seats on its highest trim.  

Hyundai’s Digital Key 2 Touch allows drivers to use their smartphone as a key—a feature not available on the Altima.  

Why Sonata Wins This Round

The 2025 Hyundai Sonata delivers a more spacious, comfortable, and tech-forward cabin than the 2025 Nissan Altima. From its superior passenger space and cargo capacity to its luxurious touches and cutting-edge features, the Sonata is the clear choice for drivers who want their midsize sedan to feel like a true upgrade.
