For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Accord Sedan its highest rating: “Top Pick Plus” for 2017, a rating granted to only 45 vehicles tested by the IIHS. The Optima is only a standard “Top Pick” for 2017.

Warranty Comparison

The Accord Sedan’s 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Optima runs out after 100,000 miles.

There are over 35 percent more Honda dealers than there are Kia dealers, which makes it easier should you ever need service under the Accord Sedan’s warranty.

Reliability Comparison

J.D. Power and Associates rated the Accord Sedan third among midsize cars in their 2016 Initial Quality Study. The Optima isn’t in the top three.

J.D. Power and Associates’ 2016 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Honda vehicles are more reliable than Kia vehicles. J.D. Power ranks Honda 7th in reliability, above the industry average. With 27 more problems per 100 vehicles, Kia is ranked 17th.

Tires and Wheels Comparison

The Accord Sedan Sport/Touring’s tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Optima SX/SX Limited’s 45 series tires.

For better ride, handling and brake cooling the Accord Sedan Sport/Touring has standard 19-inch wheels. The Optima’s largest wheels are only 18-inches.

Suspension and Handling Comparison

The Accord Sedan’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Optima doesn’t offer drift compensation steering.

The Accord Sedan Sport handles at .87 G’s, while the Optima LX 1.6T pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The Accord Sedan Touring executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the Optima LX 1.6T (26.6 seconds @ .67 average G’s vs. 27.8 seconds @ .62 average G’s).

Chassis Comparison

The Accord Sedan uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Optima doesn’t offer active noise cancellation.

Passenger Space Comparison

The Accord Sedan has .5 inches more front shoulder room, 2.9 inches more rear legroom and .1 inches more rear shoulder room than the Optima.

Cargo Capacity Comparison

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the Accord offers cargo security. The Optima’s non-lockable remote release defeats cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Accord Sedan EX/EX-L/Touring. The Optima doesn’t offer locking storage for small valuables.

Ergonomics Comparison

The Accord Sedan EX/EX-L/Touring Auto has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Optima doesn’t offer a remote starting system.

The Accord Sedan’s standard driver’s power window opens or closes with one touch of the window control, making it more convenient at drive-up windows and toll booths. The Optima’s standard driver’s power window switch has to be held the entire time to close it fully.

If the windows are left down on the Accord Sedan the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the Optima can only operate the windows from inside the vehicle, with the ignition on.

The Accord Sedan’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Optima’s manually variable intermittent wipers have to be constantly adjusted. The Accord Sedan Touring’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

Consumer Reports rated the Accord Sedan’s headlight performance “Good,” a higher rating than the Optima’s headlights, which were rated “Fair.”

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Accord Sedan’s available headlights were rated “Acceptable” by the IIHS, while the Optima’s headlights are rated “Poor.”

The Accord Sedan has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Optima and isn’t available on the Optima LX 2.4.

The Accord Sedan’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Optima LX 2.4 doesn’t offer automatic air conditioning.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the Accord Sedan is less expensive to operate than the Optima because it costs $360 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost less on the Accord Sedan than the Optima, including $64 less for a water pump, $20 less for front brake pads and $32 less for a timing belt/chain.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Honda Accord Sedan will be $2474 to $4543 less than for the Kia Optima.
