The 2018 Nissan Sentra and the Kia Optima are designed to meet the needs of drivers who enjoy a bit of adventure and aren’t afraid to take their vehicle on unbeaten paths. Both cars are sporty and athletic with their styling and performance. When you’re ready to find the next vehicle to meet your driving needs, there are a few differences to compare between the 2018 Nissan Sentra and the Kia Optima.

Interior Features

The interior of the 2018 Nissan Sentra is impressive and sleek with premium features that create a comfortable and luxe environment. The design of the interior setting is simple but is still pleasing with an exceptional amount of passenger space for its class. The infotainment system is easy to use and make adjustments to different settings in the vehicle. The buttons and layout are simple and straightforward, which will prevent you from becoming distracted while behind the wheel. Additionally, the front passenger seat can easily be folded down to create extra cargo space. Extra features that are available in the sedan include the NissanConnect smartphone integration, an eight-speaker Bose premium audio system, and satellite radio.

The cabin of the 2018 Kia Optima is well-built and includes a large trunk for extra cargo space. The black plastic on the dashboard is overwhelming, which causes the double stitching to get lost, making the cabin less stylish inside compared to the Nissan Sentra. Standard features included in the vehicle are satellite radio, a proximity key, navigation, and a touchscreen. The back seats are also spacious and comfortable.

Consumer Reviews

Owners of the 2018 Nissan Sentra appreciate the safety features that come standard in the vehicle, which includes blind spot monitoring, rear cross traffic alert, and automatic emergency braking. The tech features that are included are also an additional perk with a push-button start and a five-inch touchscreen available for convenience. The styling of the exterior is also favorable among consumers due to the sleek design of the back of the car with tail lights that look edgy and sharp. Chrome accent details also add a classy touch to the body.

The 2018 Kia Optima now includes Apple CarPlay and Android Auto, which allows consumers to easily connect their smartphone to the car while on the go. The car is also quicker than average and takes 6.7 seconds to reach 60 mph. Unfortunately, the car doesn’t feel as sporty as it looks with steering that feels heavy. The steering response is sluggish and makes it easy to feel less in control of the car compared to the Nissan Sentra.


Inside, a high level of visibility is provided and outside noise and wind is muffled by the acoustically insulated windshield and the insulation in the doors of the car. The car has one of the largest interiors in its class with an ample amount of head- and legroom. The seats are supportive but are still comfortable.

The 2018 Kia Optima offers a comfortable ride with power-adjustable front seats and a heated steering wheel. Less visibility is available in the front and back of the car compared to the Sentra. Fortunately, the panoramic sunroof that is available offers a great view of the sky. The low anchors that are available to install car seats are difficult to find because they’re built low into the seats of the vehicle.
