Proudly Serving Gainesville, GA

The 2018 Kia Optima and Nissan Altima both make excellent choices, especially if you’re shopping for a mid-size sedan that supplies a smooth, comfortable ride. These models are also known for their modern infotainment options and high-tech safety aids. The latter help you stay vigilant, even in heavy rush-hour traffic. Which sedan is right for you? Read our comparison guide to learn more.

Passenger Comfort

When it comes to a cozy cabin, the 2018 Kia Optima leads the way. Every model, from the base LX to the top-trim SX, provides a spacious cabin, with generous head- and legroom in both rows. The front seats are perfect for long rides, thanks to their impressive lateral support and wide cushions. The back seats are also road-trip-ready. Your favorite passengers members will love how much elbowroom they have to text friends and play games on their devices.

Compared to the Optima, the Altima is a bit less luxurious. In your Optima, you can add handsome leather upholstery and upscale features, like heated and ventilated front seats. The Altima offers heated seats to ward off winter weather, but not ventilation. Therefore, the Optima does a better job cooling you down on a summer afternoon. We wish there were a few more driver-seat adjustments in the Altima as well.

Technology and Infotainment Features

To stay connected throughout your travels, choose the 2018 Kia Optima. Every single Optima come standard with a 7-inch central touchscreen. Even if you’re not big on technology, you’ll find Kia’s Uvo infotainment system easy to use. All Optimas also come standard with Android Auto and Apple CarPlay capabilities. These systems display smartphone apps, like Maps and Messages, on your central touchscreen, so you don’t have to look down at your phone while stuck in traffic.

In the 2018 Nissan Altima, you can get complete smartphone integration with Apple CarPlay and Android Auto, but only on the top-trim 3.5 SL model. That means you’ll have to pay extra to enjoy this technology.


The 2018 Kia Optima is also our pick for power and performance. This mid-size sedan supplies plenty of power for highway merging and passing maneuvers. The Optima also impresses with its handling. You’ll take on twisty roads and tight corners with total confidence. This sedan provides impressive braking performance, giving you the stopping power you need to bring the Optima up short of danger.

The 2018 Nissan Altima gets pretty high marks for handling, too. However, the powertrain doesn’t supply as much kick. As you merge onto highways, you’ll likely wish this sedan was a bit more responsive to your input.
