Safety

The rear seatbelts optional on the MKZ inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The Q70 doesn’t offer inflatable seatbelts.

The MKZ’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 Q70 doesn’t offer a driver alert monitor.

Compared to metal, the MKZ’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Infiniti Q70 has a metal gas tank.

Both the MKZ and the Q70 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available all wheel drive, daytime running lights and front parking sensors.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Lincoln MKZ is safer than the Infiniti Q70:

Warranty

There are over 4 times as many Lincoln dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the MKZ’s warranty.

Reliability

The MKZ has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The Q70 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

The battery on the MKZ is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the MKZ’s battery 20 to 30 degrees cooler, its life is increased by years. The Q70’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Lincoln vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Lincoln 7th in initial quality, above the industry average. With 9 more problems per 100 vehicles, Infiniti is ranked 14th.

Fuel Economy and Range

On the EPA test cycle the MKZ Hybrid gets better fuel mileage than the Q70 3.7 LUXE RWD (42 city/39 hwy vs. 18 city/25 hwy).

Regenerative brakes improve the MKZ Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The Q70 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the MKZ Hybrid’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Q70 doesn’t offer an automatic engine start/stop system.

The MKZ 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 Q70 doesn’t offer a cap-less fueling system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lincoln MKZ higher (5 to 7 out of 10) than the Infiniti Q70 (3). This means the MKZ produces up to 24.5 pounds less smog-producing pollutants than the Q70 every 15,000 miles.

Transmission

The MKZ 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 Q70 doesn’t offer a CVT.

Brakes and Stopping

The MKZ stops shorter than the Q70:

Tires and Wheels

The MKZ’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Q70’s standard 50 series tires.

Suspension and Handling

The MKZ has a standard 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 Q70’s suspension doesn’t offer adjustable shock absorbers.

The MKZ’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 Q70 doesn’t offer drift compensation steering.

The MKZ AWD handles at .84 G’s, while the Q70 3.7 LUXE pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The front grille of the MKZ Hybrid uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Q70 doesn’t offer active grille shutters.

As tested by Car and Driver while under full throttle, the interior of the MKZ AWD is quieter than the Q70 3.7 LUXE (75 vs. 77 dB).

Passenger Space

The MKZ has .8 inches more front hip room, .8 inches more rear legroom and .3 inches more rear hip room than the Q70.

Cargo Capacity

The MKZ has a larger trunk than the Q70 (15.4 vs. 14.9 cubic feet).

The MKZ’s standard rear seats fold to accommodate long and bulky cargo. The Q70 doesn’t offer folding rear seats, only a ski pass-through.

To make loading and unloading groceries and cargo easier, especially for short adults, the MKZ offers an optional power trunk, which opens and closes automatically by pressing a button. The Q70 doesn’t offer a power trunk.

Towing

The MKZ has a 1000 lbs. towing capacity. The Q70 has no towing capacity.

Servicing Ease

The MKZ has a maintenance free battery for long life without checking the battery’s water level. The Q70 doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

Ergonomics

The MKZ 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 Q70 doesn’t offer a remote starting system.

The power windows standard on both the MKZ and the Q70 have locks to prevent small children from operating them. When the lock on the MKZ is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Q70 prevents the driver from operating the other windows just as it does the other passengers.

The MKZ’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 Q70’s rear power window switches have to be held the entire time to open or close them fully.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the MKZ’s exterior PIN entry system. The Q70 doesn’t offer an exterior PIN entry system, and its extra cost INFINITI Connection can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

While driving with high beams on, sensitive light sensors standard on the MKZ detect other vehicles which could be blinded and automatically switch to low beams. The Q70 doesn’t offer automatic dimming high beams.

Standard SYNC for the MKZ allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations and other connected activities without taking their eyes off the road or their hands from the wheel. The Q70 doesn’t offer factory integrated smartphone program access.

The MKZ offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Q70 doesn’t offer a house-current electrical outlet.

The MKZ’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 Q70 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the MKZ owner. The Complete Car Cost Guide estimates that insurance for the MKZ will cost $2710 less than the Q70 over a five-year period.

According to The Car Book by Jack Gillis, the MKZ is less expensive to operate than the Q70 because it costs $18 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the MKZ than the Q70, including $334 less for a water pump, $51 less for front brake pads, $167 less for a starter, $549 less for front struts, $163 less for a timing belt/chain and $64 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Lincoln MKZ will be $17885 to $18660 less than for the Infiniti Q70.

Recommendations

The Lincoln MKZ outsold the Infiniti Q70 by almost five to one during the 2018 model year.
