Overview

The Kia Optima has been a player in the midsize sedan class since 2001, but only in the past few years has it become a force to be reckoned with. Kia has been working to keep the Optima fresh in light of new and updated competitors, even in the years between generational redesigns or refreshes, and this continues with the 2018 model.
In both its previous generation and its current form, the Optima is considered to be one of the best-looking midsize sedans on the market. Details like a wide tiger-nose grille, LED accent lighting, a coupe-like roofline, and wheels ranging in size from 16 to 18 inches help set the Optima apart from its competitors. New for 2018 is the S trim, which is slotted between the LX and EX. Positioned as a sporting model, the S adds a unique front bumper, a rear spoiler, LED fog lights and taillights, and 17-inch alloy wheels.
The Optima’s interior displays significantly less flair than its exterior, with a design focused on function over form. Controls are laid out in a logical fashion within easy reach and material quality is about average, with a combination of soft-touch and hard plastics throughout. The front seats provide enough comfort for long trips, although some will be wishing there was a bit more side bolstering when the Optima goes around corners. Rear passengers will find plenty of legroom but limited headroom, leaving taller passengers feeling somewhat cramped. Trunk space is large for the class at 15.9 cubic feet.
For entertainment needs, Kia’s UVO infotainment system with a 7-inch display, a reversing camera, and a 6-speaker AM/FM/MP3/satellite audio system comes standard on all trims. An 8-inch color touchscreen with navigation and a premium Harman Kardon Surround Sound system are available upgrades for the EX and SX trims. Both the 7- and 8-inch systems come with Android Auto and Apple CarPlay.
The Optima offers a good selection of powertrain options. The LX, S, and EX trims come with a 2.4-liter 4-cylinder engine with 185 hp and 178 lb-ft of torque, while the LX 1.6T receives a turbocharged 1.6-liter 4-cylinder engine good for 178 hp and 195 lb-ft. The SX, meanwhile, features a turbocharged 2.0-liter 4-cylinder engine with an output of 245 hp and 260 lb-ft. A 6-speed automatic transmission comes standard for the 2.4-liter and the turbo 2.0, while the turbo 1.6 gets a 7-speed dual-clutch transmission (DCT). Fuel-economy figures for the 2018 Optima range from 22 mpg city, 31 highway, and 25 combined with the turbo 2.0 to 28, 37, and 31 with the turbo 1.6.
The Optima’s 2.4-liter engine will be sufficient for most drivers, as it offers decent power for daily driving and a 6-speed automatic with smooth and quick shifts. The turbo 1.6 has plenty of oomph but is somewhat hampered by the DCT, which is programmed to quickly upshift for better fuel economy. For those power-hungry folks, the turbo 2.0 will fulfill your need for speed with its robust acceleration. Separate hybrid and hybrid plug-in models are also available.
Kia has been working on improving handling for the Optima, and the 2018 model shows sharp reflexes with little body roll on twisty roads. It’s a shame the Optima is let down by the steering, which is too light on weight and feel for truly exuberant driving. Ride quality is about average for the class—small bumps and imperfections are smoothed over, while larger bumps will cause some jostling. Some road noise does enter the cabin, but wind noise is almost nonexistent.
Kia has improved the Optima’s safety credentials for 2018 by adding blind-spot monitoring, rear cross-traffic alert, and rear parking sensors as standard equipment. Also standard are a full complement of airbags, traction and stability control, and anti-lock brakes (ABS). Optional safety equipment includes adaptive cruise control, automatic emergency braking, forward-collision warning, lane-departure warning, a surround-view camera system, and automatic high beams. The Insurance Institute for Highway Safety (IIHS) awarded the 2017 Optima Top Safety Pick+ status, while the 2018 model earned a 5-star overall rating from the National Highway Traffic and Safety Administration (NHTSA).
The 2018 Optima starts at $22,500 for the base LX trim.

The Kia Optima has a very smooth ride and easy to handle. The A/C is very cold. The car is also very comfortable and the back seat has plenty of leg room for all three teenagers.

Is the 2018 Kia Optima a good car?
Yes — the 2018 Kia Optima earns a 4.64/5 user rating, which points to strong owner satisfaction. Owners most often praise its smooth ride, comfort, and good fuel economy, and they also like the spacious interior and updated tech features. That combination makes it appealing if you want a midsize sedan that feels practical and easy to live with. With 30.6% of listings marked as good or great deals, you have a decent chance of finding a competitive price.
Is the 2018 Kia Optima reliable?
Owners rate it 4.64/5, a strong signal of long-term satisfaction.
The owner feedback also points to a car that many drivers find reliable, dependable, and trouble-free over the long term. That said, some owners mention specific mechanical concerns, so you should still pay close attention to maintenance history and current condition. For used buyers, the main long-term ownership risk is ending up with a car that has been poorly maintained or has unresolved issues.
What should I look for when buying a used 2018 Kia Optima?
At 54.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should start with a vehicle history report so you can separate clean examples from cars with accident records. After that, prioritize a thorough pre-purchase inspection, especially if the listing price looks unusually attractive. Focus on overall condition, maintenance evidence, and any signs of unresolved mechanical issues before you commit.
Is now a good time to buy a used 2018 Kia Optima?
This is a moderate market, so you can shop selectively without expecting a deep buyer's-market bargain on every listing.
- Deal availability: 30.6% of listings are priced as good or great deals.
- Inventory: There are 1,154 listings available.
- Price trend: Prices have softened 6.60% compared with last year.
- Clean inventory: 54.5% of listings are accident-free.
If you find a listing below $10,622, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2018 Kia Optima's resale value?
The current average of $11,008 sits slightly below last year's $11,786.
That softer pricing suggests the market has become a bit more favorable for buyers, but it can also mean future sellers may face some pressure if prices continue to ease. If you buy at a competitive number now, you may help protect your position when it's time to sell. Strong owner satisfaction can also support demand later, especially for shoppers looking for a well-liked midsize sedan.
Vehicles with strong owner satisfaction ratings, like this model year's 4.64/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2018 Kia Optima or consider a different year?
If you're weighing the 2018 against nearby model years, here's how to think about it:
Choose the 2018 if:
- 30.6% of listings are priced as good or great deals.
- At 54.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 6.60% compared with last year.
- Owners rate it 4.64/5 — a strong satisfaction signal.
Consider the 2019 if:
- At $12,165, the 2019 costs more than the current year's $11,008 average.
- It adds stylish looks, more engine choices, and sophisticated safety technologies.
The bottom line: If you want the better value play, the 2018 is the stronger starting point because it combines a lower average price with solid owner satisfaction. If you're willing to spend more for a newer model year with a broader feature set and a more polished overall package, the 2019 is the better secondary path.
