Safety

The middle row seatbelts optional on the MKT 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 QX80 doesn’t offer inflatable seatbelts.

For better protection of the passenger compartment, the MKT uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The QX80 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the MKT and the QX80 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available collision warning systems, lane departure warning systems, blind spot warning systems, front parking sensors and rear cross-path warning.

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 MKT’s warranty.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the MKT has a standard 200-amp alternator. The QX80’s 150-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2017 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 9th in initial quality, above the industry average. With 15 more problems per 100 vehicles, Infiniti is ranked 23rd, below the industry average.

Fuel Economy and Range

On the EPA test cycle the MKT AWD turbo V6 gets better fuel mileage than the QX80 AWD (15 city/21 hwy vs. 13 city/19 hwy).

The MKT 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 QX80 doesn’t offer a cap-less fueling system.

Tires and Wheels

The MKT’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the QX80’s standard 60 series tires. The MKT’s optional tires have a lower 45 series profile than the QX80’s optional 50 series tires.

Suspension and Handling

The MKT 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 or off-road. The QX80’s suspension doesn’t offer adjustable shock absorbers.

The MKT’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 QX80 doesn’t offer drift compensation steering.

The MKT AWD handles at .76 G’s, while the QX80 AWD pulls only .72 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The Lincoln MKT may be more efficient, handle and accelerate better because it weighs about 950 pounds less than the Infiniti QX80.

The MKT is 8.4 inches shorter in height than the QX80, making the MKT much easier to wash and garage and drive (lower center of gravity).

Unibody construction makes the MKT’s chassis much stiffer, which contributes to better handling, and enables softer springs to be used for a better ride. Unibody construction’s stiffness also contributes to better durability and less body squeaks and rattles. The QX80 doesn’t use unibody construction, but a body-on-frame design.

Passenger Space

The MKT has .2 inches more front headroom, 3.4 inches more front legroom, .8 inches more rear legroom and 4.2 inches more third row legroom than the QX80.

Flexibility is maximized at the game, campground or a drive-in theatre in the MKT 3.5L GTDI when its tailgating rear seats are deployed, allowing people to sit facing out of the liftgate. (Do not use while vehicle is in motion.) The QX80 doesn’t offer tailgating seats.

Cargo Capacity

The MKT’s cargo area provides more volume than the QX80.

Servicing Ease

The MKT has a maintenance free battery for long life without checking the battery’s water level. The QX80 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 power windows standard on both the MKT and the QX80 have locks to prevent small children from operating them. When the lock on the MKT is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX80 prevents the driver from operating the other windows just as it does the other passengers.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the MKT’s exterior PIN entry system. The QX80 doesn’t offer an exterior PIN entry system, and its Infiniti Connection can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

The MKT has standard front air conditioned seats and the MKT Reserve offers them optionally in the second row. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The QX80 doesn’t offer air-conditioned seats for the second row.

The MKT Reserve’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 QX80 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the MKT owner. The Complete Car Cost Guide estimates that insurance for the MKT will cost $1005 to $3867 less than the QX80 over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Lincoln MKT will be $17586 to $34279 less than for the Infiniti QX80.

Recommendations

The MKT was chosen as one of Automobile Magazine’s “All Stars” in 2009. The QX80 has never been an “All Star.”
