5 reasons to buy the 2018 Kia Optima

1. Turbocharged engine options

The 2018 Kia Optima is available with a number of engine configurations to suit your driving needs, starting with a 2.4L four-cylinder (185 hp) that's standard on its base LX trim. Meanwhile, a turbocharged 1.6L four-cylinder at 178 hp comes equipped on the LX 1.6T trim, and an even more powerful turbocharged 2.0L four-cylinder at 245 hp is outfitted on the range-topping SX trim. Regardless of engine configuration, every 2018 Optima comes with front-wheel drive.

2. Spacious and comfortable design

Even on the base LX trim, the 2018 Optima offers a comfortable ride for front- and rear-seat occupants alike. Even on the base LX trim, height-adjustable front seats (with two-way lumbar adjustment for the driver's seat) are standard, which provides added comfort on longer road trips. Meanwhile, stepping up to the midrange EX adds dual-zone climate control for more customized temperature settings. In addition to the comfortable and spacious cabin, the 2018 Optima boasts a roomy 15.9 cu-ft. trunk for hauling groceries, luggage, and other essentials.

3. A trim for every driver

The 2018 Kia Optima is available in five trim options, so most drivers will be able to find a model that suits their tastes. Trim configurations include the base LX, turbocharged LX 1.6T, sporty S, luxurious EX, and the range-topping SX. Standard equipment on the base LX is generous and includes Bluetooth® connectivity, smartphone integration, a seven-inch touchscreen display, and a booming six-speaker sound system.

4. Plenty of driver aids

The 2018 Optima doesn't skimp on driver-assistance features—and you don't even have to pay extra for them. Standard equipment in this category includes a rearview camera, blind-spot monitoring system with rear cross-traffic alert, and rear parking sensors. Looking for a model with adaptive cruise control? Check out the range-topping SX trim for this and a lane-departure warning system with automatic emergency braking.

5. Sporty performance features

The 2018 Optima is a great choice if you're looking for a midsize sedan that has a second life as a sports car. This is especially true on the SX trim, where you'll find such performance features as a sport-tuned suspension, steering wheel paddle shifters, a rear spoiler, and dual exhaust tips.
