Overall Design
Compared side by side, it's easy to see how similar the Sonata and Altima appear to be. Dimensions between the two vary by less than an inch in each dimension, and both provide Nashua drivers with a sleek look. You'll also see many of the same exterior features across these sedans, including LED headlights and Daytime Running Lights, though the Hyundai Sonata does come with the extra benefit of LED taillights.
You'll continue to see similarities on the inside, with both sedans offering standard six-way adjustable or available eight-way power-adjustable driver's seats, standard manual air conditioning or available dual-zone automatic climate control and standard cloth or available leather upholstery. It should be noted, however, that the Sonata's cloth upholstery uses a more-refined material than the Altima's.
While the Sonata and Altima both offer Wilmington shoppers heated front seats, it remains an optional feature on most of the Altima's trim levels. The Hyundai Sonata comes with heated front seats standard starting with the Sonata SEL, its second trim level. Additionally, while both sedans' top trim levels come with power-adjustable front passenger's seats, this is only four-way adjust for the Altima, while the Sonata provides the front passenger with six-way power adjust.
