Introduction
The 2nd generation of the Audi A7 is a special example of
the new Audi design language. Viewed from any perspective, the wider low-set grill and the athletic lines exude
sportiness and progressiveness. Flared wheel arches
accommodating up to 21 inch rims hint at Audi A7 quattro
genes.

The full range of Audi connect services has been adopted
from the Audi A8 to make the Audi A7 a fully networked
Gran Turismo model in the Audi portfolio. With a total of
39 driver assist systems, the Audi A7 is a perfect companion on the road.

Overview
The impressive appearance of the Audi A7 is due mainly to
its dynamic and elegant character and a completely new
interior design. Like the Audi A8, the Audi A7 is based on
Mild Hybrid Electric Vehicle (MHEV) technology.

Engine
3.0 ltr. V6 TFSI engine with twin-scroll turbocharger
>> Maximum power: 335 hp (250 kW)
>> Maximum torque: 369 lb ft (500 Nm)

Driver assist sensors
Control Module for Adaptive Cruise Control J428
is installed in the top left corner of the grill.
Laser Distance Regulation Control Module
J1122 is installed in the top right corner of the
grill.

Audi laser light
The Audi laser light is used and an auxiliary high
beam supplementing the LED high beam. The
laser spot is activated in addition to the LED high
beam at road speeds over approximately 37 mph
(60 km.h). This allows the high beam distance to
be virtually doubled.

Displays and operation

Power transmission

The operating and display concept on the Audi A7 uses
an MMI touch response system with two touchscreens,
a switch module (optional) and a light switch module
with haptic and acoustic feedback. Also integrated are
intelligent handwritten letter input with full-word and
multi-finger recognition. An Audi virtual cockpit with
full HD resolution and a head-up display are optionally
available.

Power transmission on the Audi A7 is exclusively via an
automatic transmission. New features include the following:
>> quattro with ultra technology
>> 7-speed dual clutch transmission 0HL
>> New selector mechanism featuring shift-by-wire
technology
For further information, refer to the section starting on
page 26.

New light design
A design highlight on the Audi A7 is the full-width tail-light
band.

Electrical system
The Audi MHEV technology is based on a
newly developed 48 Volt main electrical
system which also supplies power to the
12 Volt electrical subsystem. The 48 Volt
electrical system is powered by a beltdriven starter generator (BSG) which is connected to the engine’s belt drive. A lithium-ion battery, located underneath the
luggage compartment floor, is used to
store power.

Body
Overview
Like its predecessor, the body of the Audi A7 is a composite
construction using various materials. In addition to various
grades of steel, die-cast aluminum is used for the front
suspension turret and for the node castings on the rear roof
frame. An aluminum reinforcement plate is located on the
D-pillar.
The bumper carriers with crash boxes, the body brace and
the reinforcement struts on the underbody are manufactured from extruded aluminum profiles and the attachments from sheet aluminum.

The upper shell of the rear roof frame is made of a new type
of steel/plastic composite material.
The main joining technologies used are (for steel) spot
welding and laser welding on the sill panels, laser soldering
on the roof/water channel and (for steel aluminum composite materials) punch riveting with adhesive bonding.

Body structure
The high torsional strength and crash safety of the body structure on the Audi A7 is achieved by the intelligent mixture of
different high-strength to ultra-high-strength types of sheet steel.

The number of ultra-high-strength hot-formed sheet steel
parts in the passenger compartment has been increased.
Some of these steel parts are hardened; others consist of
tailored blanks with variable wall thicknesses.

They are used in the lower area of the bulkhead, the side
members, the rear seat cross members, the top section of
the tunnel, the rear longitudinal members, the B-pillars
and the A-pillars.

669_119

Composite steel/plastic material
One of the innovations and a special feature is the use of
composite steel/plastic material for the top section of the
rear roof cross member. In this material, a 0.4 mm thick
plastic sheet is combined with 0.2 mm thick steel sheets to
form a composite sheet. The rigidity and flexural strength
is similar to comparable steel parts, while the weight is
significantly lower.

In the production process, the semi-finished product is
deep-drawn just like a regular steel sheet and the two
halves of the roof cross member are joined by punch riveting and adhesive bonding. Punch rivets and additional
adhesive are also used to join the aluminum cast nodes at
the sides.

Body assembly
Front bumper
To minimize the risk of a pedestrian sustaining knee injuries
in the event of a collision with the Audi A7, a mechanism is
integrated in the end plate of the front bumper cover to
prevent the bumper cover from springing back against the
pedestrian’s knee.
This mechanism pushes the end plate into the headlight
mounting where it latches onto a set of teeth which hold it
there. Because damage can occur to the detent mechanism
(for example, if the teeth are blunt or broken), both parts
must be replaced after an accident. Replacement is
intended to ensure that the mechanism functions properly
should another pedestrian accident occur.

The connection between the end plate and the headlight
mounting is made by an end plate adapter which is
designed to break on impact. This end plate adapter is the
first part to break in small impacts, for example, when
parking. In this case, the end plate does not latch onto the
headlight mounting. The end plate and the headlight
mounting can continue to be used; only the adapter has to
be replaced.

Instrument panel
The appearance and design of the A7 instrument panel is
similar to the 2019 A8 but its structure is fundamentally
different. The air outlets do not swivel electrically and do
not have the movable covers. Because the trim on the

passenger side surrounds the MMI screen and forms a
single unit with the top panel, the procedure for disassembling the instrument panel is different to the Audi A8.
Always follow the instructions in the most recent service
literature.

669_133

Rear spoiler
Like its predecessor, the Audi A7 has a retractable spoiler in
the rear lid. At speeds above approximately 75 mph (120
km/h), Rear Spoiler Motor V52 automatically extends the
spoiler blade. The spoiler is automatically retracted when
the speed drops below approximately 50 mph (80 km/h). A
button in Front Information Display Control Head 2 J1060
can also be used to operate the spoiler manually. To retract
the spoiler at speeds up to 12 mph (20 km/h), the button
in J1060 must be held until the spoiler is fully retracted.
The following corresponding messages appear on the MMI
display J685: "Press and hold to retract rear spoiler manually" and "The rear spoiler is retracted." At speeds above 12
mph (20 km/h) the button only needs to be pressed briefly.

Two Hall sensors monitor whether the spoiler has reached
the end positions. One of the sensors measures the end
position of the extended rear spoiler while the other counts
the number of drive motor revolutions while the spoiler is
being retracted.
Adjusters allow the height of the spoiler blade to be
