The Kia Optima and the Nissan Altima are two stylish and efficient sedans. They're great choices for driving to work and running errands around Ithaca, Corning, and Cortland, NY. Which one is right for you, though? To help you decide, the team at Maguire Kia looks at what they have to offer in this 2020 Kia Optima vs. Nissan Altima comparison.

Interior Dimensions

The 2020 Kia Optima and the Nissan Altima both offer seating for five. The Kia keeps you more comfortable, though, with a little extra space. Throughout the interior, the Kia features 104.8 cubic feet of passenger space. The Nissan has a slightly smaller cabin with 100.8 cubic feet of passenger space.

You'll feel the difference whether you're behind the wheel or riding in the back seat. The Kia Optima gives the driver and front passenger 39.8 inches of headroom and 45.5 inches of legroom. The second row has 37.8 inches of headroom and 35.6 inches of legroom.

The Nissan Altima may feel like a tighter squeeze. The front seats offer 39.2 inches of headroom and 43.8 inches of legroom, while passengers in the back have 36.9 inches of headroom and 35.2 inches of legroom.

The Kia also gives you some extra cargo room with 15.9 cubic feet of trunk space. The Nissan has a slightly smaller trunk with only 15.4 cubic feet of cargo room.

Safety Features

You can count on the Kia Optima to help keep you safe, too. It comes with lots of driver-assistance features that will give you more awareness during your drive and help prevent accidents. Some of the standard features include:

  • Forward Collision-Avoidance Assistance with Pedestrian Detection
  • Lane Departure Warning
  • Blind Spot Collision Warning
  • Driver Attention Warning

The Nissan Altima also offers a Blind Spot Warning, Lane Departure Warning, and Emergency Braking. Unfortunately, none of those features comes standard on every trim level. Plus, it doesn't offer anything that reminds you to focus on the road, like the Driver Attention Warning in the Kia Optima.

Interior Amenities

Both sedans come with an 8-inch touch-screen that includes lots of smartphone compatibility. You'll be able to sync your apps with Apple CarPlay® and Android Auto™, plus stream music and make hands-free phone calls with Bluetooth®.

While both vehicles come with USB charging ports, the Kia Optima makes it easier to charge your phone with an available wireless charging station. The Nissan Altima doesn't offer any wireless charging capabilities.

If you're streaming your favorite playlist, you can enjoy better sound quality in the Kia with a 10-speaker Harman Kardon® QuantumLogic™ Premium Sound System with Clari-Fi™. The Nissan only offers a 9-speaker sound system.

There's nothing more fun than blasting your favorite tunes on a sunny day, too. The Kia Optima is designed to help you capture that feeling with a Panoramic Sunroof. The Nissan Altima only offers a moonroof, so you may not be able to play your music as loudly or let in any fresh air.
