Fuel Economy and Range

On the EPA test cycle the Ioniq Hybrid gets better fuel mileage than the MKZ Hybrid (57 city/59 hwy vs. 42 city/39 hwy).

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Hyundai Ioniq Hybrid higher (7 out of 10) than the Lincoln MKZ (5 to 7). This means the Ioniq Hybrid produces up to 8 pounds less smog-producing pollutants than the MKZ every 15,000 miles.


The Ioniq Hybrid offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The MKZ doesn’t offer an SMG or a conventional manual transmission.

Suspension and Handling

The Ioniq Hybrid has standard front gas-charged shocks for better control over choppy roads. The MKZ’s suspension doesn’t offer gas-charged shocks.

For better maneuverability, the Ioniq Hybrid’s turning circle is 4.2 feet tighter than the MKZ’s (34.78 feet vs. 39 feet).


The Hyundai Ioniq Hybrid may be more efficient, handle and accelerate better because it weighs about 750 to 1100 pounds less than the Lincoln MKZ.

The Ioniq Hybrid is 1 foot, 5.9 inches shorter than the MKZ, making the Ioniq Hybrid easier to handle, maneuver and park in tight spaces.

Cargo Capacity

A low lift-over trunk design makes loading and unloading the Ioniq Hybrid easier. The Ioniq Hybrid’s trunk lift-over height is 28.8 inches, while the MKZ’s liftover is 30.5 inches.


The Ioniq Hybrid has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The MKZ doesn’t offer a locking fuel door.

Consumer Reports rated the Ioniq Hybrid’s headlight performance “Very Good,” a higher rating than the MKZ’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.
