Interior Comparison

Both the 2025 K5 and the 2025 Altima offer five-passenger seating, but the Kia model boasts a longer wheelbase at 112.2 inches. The result is almost three inches more legroom for the driver and front-row passenger to stretch out.

The base model of both the 2025 K5 and the 2025 Altima has a six-way adjustable driver’s seat. What sets the Kia apart is its 10-way adjustable driver’s seat that is standard on the rest of the lineup. The Nissan model only goes up to eight.

The 60/40 split-folding rear seats are standard on both the 2025 K5 and the 2025 Altima, allowing users to expand the cargo room and accommodate odd-sized items.

The 2025 K5 also features a panoramic sunroof with a power sunshade (available in the GT-Line FWD/AWD grades and standard on the GT and EX). The 2025 Altima only offers it as part of its SV Special Edition package.

It is the only grade across both models that makes 290 horsepower and 311 lb-ft of torque.
