The rear suspension of the i4 uses air springs for a smoother, controlled ride than the ID.4, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.
The i4 offers an optional 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 ID.4’s suspension doesn’t offer adjustable shock absorbers.
The i4 has a standard automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The ID.4 doesn’t offer a load leveling suspension.
For a smoother ride and more stable handling, the i4’s wheelbase is 3.7 inches longer than on the ID.4 AWD (112.4 inches vs. 108.7 inches). The i4’s wheelbase is 3.5 inches longer than on the ID.4 (112.4 inches vs. 108.9 inches).
For better handling and stability, the average track (width between the wheels) on the i4 is .1 inches wider in the front and 1.7 inches wider in the rear than the average track on the ID.4.
The i4 M50 handles at .96 G’s, while the ID.4 pulls only .85 G’s of cornering force in a Car and Driver skidpad test.
