Safety Comparison

For enhanced safety, the front, middle and rear seat shoulder belts of the Infiniti QX60 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes GLS doesn’t offer height-adjustable middle seat belts.

Over 200 people are killed each year when backed over by motor vehicles. The QX60 offers an optional Backup Collision Intervention which uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The GLS doesn’t offer backup collision prevention brakes.

To help make backing safer, the QX60’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLS doesn’t offer a cross-path warning system.

Both the QX60 and the GLS 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, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the QX60 the rating of “Top Pick” for 2017, a rating granted to only 113 vehicles tested by the IIHS. The GLS has not been tested, yet.

Warranty Comparison

The QX60 comes with a full 4 year/60,000 mile basic warranty, which covers the entire truck and includes 24 hour roadside assistance. The GLS’ 4 year/50,000 mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the QX60 2 years and 20,000 miles longer than Mercedes covers the GLS. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the GLS ends after only 4 years or 50,000 miles.

The QX60’s corrosion warranty is 2 years longer than the GLS’ (7 vs. 5 years).

Reliability Comparison

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the QX60’s reliability 19 points higher than the GLS.

J.D. Power and Associates’ 2016 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Infiniti 12th in initial quality, above the industry average. With 8 more problems per 100 vehicles, Mercedes is ranked 15th, below the industry average.

Fuel Economy and Range Comparison

On the EPA test cycle the QX60 Hybrid AWD gets better fuel mileage than the GLS450 (25 city/27 hwy vs. 17 city/22 hwy).

On the EPA test cycle the QX60 3.5 AWD gets better fuel mileage than the GLS450 V6 (19 city/26 hwy vs. 17 city/22 hwy).

Regenerative brakes improve the QX60 Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The GLS doesn’t offer a regenerative braking system.

Consumer Reports

Suspension and Handling Comparison

The QX60 3.5 AWD handles at .76 G’s, while the GLS450 pulls only .74 G’s of cornering force in a Car and Driver skidpad test.

The QX60 3.5 AWD goes through AutoWeek’s slalom 1.7 MPH faster than the GLS350d (39.1 vs. 37.4 MPH).

For better maneuverability, the QX60’s turning circle is 2 feet tighter than the GLS’ (38.7 feet vs. 40.7 feet).

Chassis Comparison

The Infiniti QX60 may be more efficient, handle and accelerate better because it weighs about 1000 to 1050 pounds less than the Mercedes GLS.

The design of the Infiniti QX60 amounts to more than styling. The QX60 has an aerodynamic coefficient of drag of .33 Cd. That is significantly lower than the GLS (.369 to .38) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the QX60 get better fuel mileage.

The QX60 Hybrid uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLS doesn’t offer active noise cancellation.

Passenger Space Comparison

The QX60 has 2 inches more front legroom, 1.8 inches more front shoulder room, 3.2 inches more rear legroom, 2.1 inches more rear shoulder room and 6.6 inches more third row shoulder room than the GLS.

For enhanced passenger comfort on long trips the QX60’s middle and third row seats recline. The GLS’ third row seats don’t recline.

Cargo Capacity Comparison

To make loading groceries and cargo easier when your hands are full, just kicking your foot under the back bumper can open the QX60’s cargo door, leaving your hands completely free. The GLS doesn’t offer a hands-free gesture to open its cargo door, forcing you to put cargo down if your hands are full.

Ergonomics Comparison

The QX60 offers a 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 GLS doesn’t offer a remote starting system.

To improve rear visibility by keeping the rear window clear, the QX60 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLS only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the QX60’s headlight performance “Very Good,” a higher rating than the GLS’ headlights, which were rated “Good.”

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the QX60 is less expensive to operate than the GLS because typical repairs cost much less on the QX60 than the GLS, including $183 less for a water pump, $152 less for an alternator, $165 less for front brake pads, $336 less for a starter, $229 less for fuel injection and $93 less for a fuel pump.

Recommendations Comparison

The Infiniti QX60 outsold the Mercedes GLS by 47% during the 2016 model year.
