Get Body -> Body assembly Guide for Audi RS E Tron Gt 4 Door First Generation (2021-2026)

Battery frame

The battery frame made of aluminum extrusions not only provides the highest possible protection in the event of an accident but

also increases the body’s torsional rigidity. If the battery frame is damaged, it must be replaced.

Underbody guard

The underbody guard is made of aluminum and is bolted and bonded onto the battery frame. It protects the high-voltage battery

against damage from below (e.g. from stones) and can be replaced separately if damaged. If the battery frame (aluminum extru-

sion) is damaged, it must be replaced.

Sill panel reinforcement

The sill panel reinforcement increases the rigidity of the body in a side impact, particularly in areas that are especially relevant for

safety (such as the high-voltage battery).

Aerodynamics

Particularly on electric vehicles, the aerodynamics are a key factor for the range. Especially at high speeds, small details have a pos-

itive effect on air resistance and therefore also on the performance and efficiency of the vehicle.

Air curtains

Controlled airflow at the front wheels plays a major role in the aerodynamic concept. The side air inlets at the front of the vehicle

(the air curtains) guide the air into the wheel housings via a channel so that the wheels and the side of the vehicle have optimal

airflow. Narrow horizontal ribs in the air ducts guide the air so that disruptive swirls in the wheel housings are encapsulated. This

results in the air travelling more “cleanly” along the side of the vehicle with reduced flow losses. The design of the aerodynamic

wheels along with the profile and the embossing of the tire sidewalls are also optimised in this regard.

Underbody

684_315

The complex aerodynamic concept continues under the vehicle floor, where underbody trim with spoiler elements guides the air

cleanly around the vehicle. Trim is fitted to the entirety of the underbody (including the aluminum cover plate for the high-voltage

battery). The screw connections take the form of bowl-like indentations, similar to the dimples on a golf ball. They allow the air to

flow even more easily than a fully flat surface would.

Rear spoiler

The Audi e-tron GT (type F8) has a retractable spoiler in the rear lid. Depending on the speed, the spoiler blade is automatically

moved into two positions. A button on the MMI touch display can also be used to move the spoiler to its upper end position man-

ually. If the button is pressed for longer, the spoiler is moved back into the position corresponding to the current speed. If the

spoiler is manually moved to its end position, it stays there if the vehicle is stopped or parked. After terminal 15 is switched on, the

spoiler retracts automatically once the vehicle is travelling over 20 km/h.

End position (manual)

It is actuated by rear spoiler adjustment control unit J223. The position of the spoiler is monitored by two Hall sensors in the spoil-

er adjustment system. One of the sensors measures the end position of the extended rear spoiler, while the other counts the num-

ber of drive motor revolutions while the spoiler is being retracted.

Adjusters allow the height of the spoiler blade to be aligned vertically (z axis) in relation to the rear lid and side panel. Elongated

holes are used for alignment in the longitudinal and transverse directions (x and y axes).

Drain hoses on the right and left ensure that rainwater can be channelled out of the drive unit for rear spoiler adjustment. Since

moulded hoses are used, the markings on both sides must align with each other when the hoses are fitted onto the mountings.

Glass trim

684_307

The rear window is optically lengthened downwards with a piece of glass trim made of tinted safety glass fitted above the spoiler.

Three clips ensure that the trim is positioned correctly. It is bonded to the rear lid with window adhesive.

Rear lid

684_304

The electrically operated rear lid in the Audi e-tron GT (type F8) is operated via a spindle drive on the rear lid hinge (left-side).

Note

When motor for rear lid V444 is removed, the electrical connector must be unplugged first. The clip on the ball mount-

ing must then be pressed together with 90° angled long-nose pliers. Under no circumstances should the clip be prised

off with a screwdriver or a similar tool.

Roof

Two roof versions are available for the Audi e-tron GT (type F8); the CFRP roof or the panoramic sunroof.

14

CFRP roof

684_313

The outer section of the roof (made of clear-coated CFRP) is bonded to a frame made of extra-high-strength steel. Acoustic fleece

material at the front and rear provides the necessary noise insulation. The CFRP outer skin only weighs approx. 4.2 kg; the entire

roof (including frame, adhesive, seals and acoustic fleece) weighs approx. 10.2 kg. The uppermost, visible carbon fibre weaving has

a 0/90° orientation/a twill of 45°. This means that the parallel lines of the twill weave are diagonal to the vehicle’s longitudinal

axis.

No roof carrier system is available in conjunction with the CFRP roof.

Panoramic sunroof

The panoramic sunroof covers the entire roof surface and is permanently bonded to the vehicle body. It cannot be opened. The

laminated safety glass has an acoustic foil covering and an additional foil covering which almost entirely reflects infrared rays. An

additional low emissivity coating provides additional heat and sun protection. Retainers for a roof carrier are integrated under the

side roof trim strips. The entire panoramic sunroof (including frame, adhesive, seals and bracket) weighs approx. 22.5 kg.

Vehicle interior

684_316

A major emphasis was placed on sustainability when selecting materials for the vehicle interior.

For example, the floor mat and the carpet are made of Econyl^®.

Nylon waste which would otherwise pollute our planet (such as fishing nets, fabric remnants, carpets and industry waste are collec-

ted, sorted and cleaned to win back the nylon contained therein. In an extensive cleaning and regeneration process, nylon fibres are

created from the regenerated nylon waste and subsequently woven into, among other things, carpets for the Audi e-tron GT (type

F8).

The foam of the seat padding is made of 85 % recycled PET bottles.

The Cascade seat cover is made of 35 % recycled PET bottles and 15 % regionally recycled textile fibres. This seat cover is fitted on

the Audi e-tron GT (type F8) with leather-free interior (PR number: 7HF). In this case, the interior elements are partly covered with

leatherette and partly with the high-end microfibre Dinamica. This fibre is also primarily made of recycled polyester fibres and is

100% recyclable. The Alcantara steering wheel is fitted on this version.

17

Dash panel

684_310

The cockpit of the Audi e-tron GT (type F8) is very driver-oriented. This is achieved, on the one hand, by setting the MMI touch dis-

play at an angle towards the driver. On the other hand, the lines of the door trim and the cockpit create a visual frame around driv-

er's area. Also thanks to the mainly horizontal basic architecture, the interior of the vehicle gives a high-quality, progressive and

tidy impression. The layered structure of the dash panel must be taken into account when dismantling and assembling. It may be

necessary to remove more parts than initially expected to remove a component. Please therefore always follow the procedures de-

scribed in the most recent service literature.
