Running gear
Overview
The main system components of the running gear on the Audi e‑tron GT and the Audi RS e‑tron GT are largely identical. Any differ-
ences will be mentioned specifically in the following chapters. If information about the Audi e‑tron GT is given and no differences
are mentioned, the information also applies to the Audi RS e‑tron GT.
In the standard version, the Audi e‑tron GT is equipped with a steel spring running gear with electronic damping control. Air sus-
pension is available as an option in conjunction with electronic damping control (adaptive air suspension). The Audi RS e‑tron GT is
equipped with adaptive air suspension as standard. Both of the running gears are new developments or evolutions of those in cur-
rent Audi models.
The four-wheel steering system is available as optional equipment for the Audi e-tron GT. One of the highest priority development
goals was to achieve a low vehicle weight. The main axle components are therefore made of aluminum. Running gear control
unit J775 is also the coordination platform for the running gear systems in the Audi e‑tron GT.
If the required conditions have been met, recuperation takes place via the generator mode of the electric motor(s).The total brak-
ing power is then obtained from the hydraulic braking power and the braking power provided by the electric motor(s). The complex
regulation of these processes is performed by an electromechanical brake servo in conjunction with a 9th generation ESC system.
As on the Audi e-tron, the driver can set the level of recuperation by pulling the paddle levers on the steering wheel.
The standard version of the Audi e-tron GT is equipped with a generously proportioned steel brake system. Carbide-coated brake
discs or a ceramic brake system are available as optional equipment. The RS model has the carbide-coated brake discs as standard
equipment and can be equipped with the ceramic brake system as an option.
The range of available wheels spans from 19” (for the e-tron GT) and 20” (for the RS e-tron GT) in the standard equipment version,
to optional 21” wheels. Specially developed optimised rolling resistance tires reduce rolling resistance and help to increase the
range.
The third-generation Tire Pressure Monitoring System with direct measurement completes the comprehensive standard equip-
ment.

Axles
Overview
The axles of the Audi e‑tron GT are evolutions on the basis of the axle technology of the Porsche Panamera and Porsche Taycan.
Double wishbone axles are used at the front and the rear. The rear axle is a double wishbone axle with separate upper wishbones.
This means that one wishbone is used for the lower section while the upper section is "split” into two individual wishbones.
