The front and rear suspension of the GLS uses air springs for a smoother, controlled ride than the QX60, which uses only coil springs. Air springs maintain proper ride height and ride more smoothly.
The GLS offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Infiniti doesn’t offer an active suspension on the QX60.
The GLS 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 or off-road. The QX60’s suspension doesn’t offer adjustable shock absorbers.
The GLS has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GLS’ height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The QX60 doesn’t offer a load leveling suspension.
The GLS’ 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 QX60 doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the GLS’ wheelbase is 9.2 inches longer than on the QX60 (123.4 inches vs. 114.2 inches).
The GLS 450 handles at .87 G’s, while the QX60 Sensory AWD pulls only .80 G’s of cornering force in a Motor Trend skidpad test.
The GLS 450 executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the QX60 Sensory AWD (26.4 seconds @ .7 average G’s vs. 28 seconds @ .6 average G’s).
For greater off-road capability the GLS has a 3.4 inches greater minimum ground clearance than the QX60 (10.1 vs. 6.7 inches), allowing the GLS to travel over rougher terrain without being stopped or damaged. The GLS Off-Road Package’s minimum ground clearance is 4.6 inches higher than on the QX60 (11.3 vs. 6.7 inches).
