Using vehicle speed sensors and seat sensors, smart airbags in the Accord Hybrid deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Accord Hybrid’s side airbags will shut off if a child is leaning against the door. The Optima Hybrid’s side airbags don’t have smart features and will always deploy full force.

The Accord Hybrid’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Optima Hybrid doesn’t offer a driver alert monitor.

The Accord Hybrid EX/EX-L/Touring has standard HondaLink Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Optima Hybrid doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Accord Hybrid and the Optima Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.


The Accord Hybrid’s 5-year corrosion warranty has no mileage limitations, but the corrosion warranty on the Optima Hybrid 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 Hybrid’s warranty.


The Accord Hybrid’s 2.0 DOHC 4 cyl. hybrid produces 20 more horsepower (212 vs. 192) than the Optima Hybrid’s 2.0 DOHC 4 cyl. hybrid.

Fuel Economy and Range

On the EPA test cycle the Accord Hybrid gets better fuel mileage than the Optima Hybrid (48 city/48 hwy vs. 39 city/45 hwy).

The Accord Hybrid has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Optima Hybrid doesn’t offer a cap-less fueling system.


The Accord Hybrid has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Optima Hybrid doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the Accord Hybrid’s front brake rotors are larger than those on the Optima Hybrid:




Front Rotors

12.3 inches

12 inches

Tires and Wheels

For better traction, the Accord Hybrid has larger tires than the Optima Hybrid (225/50R17 vs. 205/65R16). The Accord Hybrid’s tires are larger than the largest tires available on the Optima Hybrid (225/50R17 vs. 215/55R17).

The Accord Hybrid’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Optima Hybrid’s standard 65 series tires. The Accord Hybrid’s tires are lower profile than the Optima Hybrid’s optional 55 series tires.

For better ride, handling and brake cooling the Accord Hybrid has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Optima Hybrid.

Suspension and Handling

The Accord Hybrid offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Optima Hybrid’s suspension doesn’t offer adjustable shock absorbers.

The Accord Hybrid’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 Hybrid doesn’t offer drift compensation steering.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Accord Hybrid a Large car, while the Optima Hybrid is rated a Mid-size.

The Accord Hybrid has .2 inches more front shoulder room, 4.8 inches more rear legroom and .1 inches more rear shoulder room than the Optima Hybrid.

Cargo Capacity

The Accord Hybrid has a much larger trunk than the Optima Hybrid (16.7 vs. 13.4 cubic feet).

The Accord Hybrid’s standard rear seats fold to accommodate long and bulky cargo. The Optima Hybrid Premium doesn’t offer folding rear seats, only a ski pass-through.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the Accord Hybrid offers cargo security. The Optima Hybrid’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 Hybrid. The Optima Hybrid doesn’t offer locking storage for small valuables.


The Accord Hybrid 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 Hybrid doesn’t offer a remote starting system.

The Accord Hybrid Touring has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Optima Hybrid doesn’t offer a heads-up display.

The Accord Hybrid EX/EX-L/Touring’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Optima Hybrid’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the Accord Hybrid the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Optima Hybrid can only operate the windows from inside the vehicle, with the ignition on.

The Accord Hybrid’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 Hybrid’s manually variable intermittent wipers have to be constantly adjusted. The Accord Hybrid Touring’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.


The Accord was chosen as one of Car and Driver’s “Top Ten” for 2018 and 22 of the last 24 years. The Optima Hybrid has never been a Car and Driver “Top Ten” pick.
