The C-MAX Hybrid’s standard 2.0 DOHC 4 cyl. hybrid produces 49 more horsepower (188 vs. 139) than the Ioniq Hybrid’s 1.6 DOHC 4 cyl. hybrid.
The C-MAX Hybrid has 1.6 gallons more fuel capacity than the Ioniq Hybrid (13.5 vs. 11.9 gallons), for longer range between fill-ups.
The C-MAX 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 Ioniq Hybrid doesn’t offer a cap-less fueling system.
For better traction, the C-MAX Hybrid has larger tires than the Ioniq Hybrid (225/50R17 vs. 195/65R15).
The C-MAX 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 Ioniq Hybrid’s standard 65 series tires.
For better ride, handling and brake cooling the C-MAX Hybrid has standard 17-inch wheels. Smaller 15-inch wheels are standard on the Ioniq Hybrid.
The C-MAX Hybrid has standard front and rear gas-charged shocks for better control over choppy roads. The Ioniq Hybrid’s suspension doesn’t offer rear gas-charged shocks.
The C-MAX 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 Ioniq Hybrid doesn’t offer drift compensation steering.
The C-MAX Hybrid has 3.5 cubic feet more passenger volume than the Ioniq Hybrid (99.7 vs. 96.2).

To make loading and unloading groceries and cargo easier, especially for short adults or children, the C-MAX Hybrid offers an optional power trunk, which opens and closes automatically by pressing a button or, optionally on the C-MAX Hybrid Titanium, by just kicking your foot under the back bumper, completely leaving your hands free. The Ioniq Hybrid doesn’t offer a power trunk.
The C-MAX Hybrid Titanium 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 Ioniq Hybrid doesn’t offer a remote starting system.
The power windows standard on both the C-MAX Hybrid and the Ioniq Hybrid have locks to prevent small children from operating them. When the lock on the C-MAX Hybrid is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Ioniq Hybrid prevents the driver from operating the other windows just as it does the other passengers.
The C-MAX Hybrid’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 Ioniq Hybrid’s standard passenger windows don’t open or close automatically. With the Ioniq Hybrid Limited’s power windows, only the front windows open or close automatically.
On a hot day the C-MAX Hybrid’s driver can lower all the windows from a distance using the keyless remote. The driver of the Ioniq Hybrid can only operate the windows from inside the vehicle, with the ignition on.
In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the C-MAX Hybrid’s available exterior PIN entry system. The Ioniq Hybrid doesn’t offer an exterior PIN entry system, and its Blue Link can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.
The C-MAX Hybrid SE’s standard variable intermittent wipers have an adjustable delay to allow the driver to choose a setting that best clears the windshield during light rain or mist. The Ioniq Hybrid’s fixed intermittent wipers only have one fixed delay setting, so the driver will have to manually switch them between slow and intermittent. The C-MAX Hybrid Titanium’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.
The C-MAX Hybrid has a 115-volt a/c outlet, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Ioniq Hybrid doesn’t offer a house-current electrical outlet.
The C-MAX Hybrid Titanium’s optional Active Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Ioniq Hybrid doesn’t offer an automated parking system.
