There won't be a shortage of wheels to choose from for the Q4 e-tron and sportback. In total there will be 11 versions from 19 to 21 inches.

  • All are aluminum wheels except for the basic version
  • Each wheel size includes "especially aerodynamic designs"
  • Audi Sport GmbH provides two 20 inch wheel options and all four 21 inch wheel options
  • 21 inch wheels - one is a matte bronze finish, one is platin gray, and another is an Aero wheel with black plastic inlays.
  • Front tires: 235 mm wide (9.25 inches)
  • Rear tires: 255 mm wide (10 inches)

Large wheels: 19- to 21-inch with mixed-sized tires The Audi Q4 e-tron and Q4 Sportback e-tron are well-grounded – their wheels comprise eleven versions ranging in size from 19 to 21 inches. Apart from the basic version, these are aluminum wheels, and each size includes especially aerodynamic designs. In the 20-inch category, two wheels come from Audi Sport GmbH, which provides all four in the 21-inch class. One of them comes in a matte bronze finish, another in platin gray. The third is an Aero wheel, which is largely covered with black plastic inlays.

All motor line-ups drive off the assembly line with a mix of tires, which further enhances stability and the sporty character. The front tires are 235 millimeters wide throughout, the rear tires 255 millimeters, while the cross sections differ depending on the rim size. All tires are optimized for rolling resistance, the 21-inch class includes a decidedly sporty tire variant for the Sportback.

Mounted behind the large wheels are powerful brakes. Depending on motor output, the disks on the front wheels measure between 330 and 358 millimeters (13.0–14.1 in) in diameter; there are extra-low-wear, low-maintenance drum brakes on the rear wheels. The drums reduce the risk of corrosion. This is because in a purely electric drive the wheel brakes are used only rarely in everyday driving – most decelerations are performed by the electric motor in the rear, which converts kinetic energy to electrical energy in the process.
