Introduction
As the most recent and compact addition to the Audi SUV
series, the Audi Q3 caters to the demands of a modern,
urban world while offering all the authentic plus-points of
an SUV (Sports Utility Vehicle). It complements the
successful Audi SUV family started with the launch of the
Audi Q7.
The Audi Q3 stands out by virtue of its sporty, muscular
appearance and its modern, coupe-like styling, and yet it is
an authentic SUV through and through. This concept makes
the Audi Q3 appealing to more than one target group
because it meets a wide variety of customer requirements.

The Audi Q3 is not what you would consider a "smaller sibling of
the Q5 and Q7", but a vehicle with a very distinctive identity. It has
the rugged character of a fully-fledged A-segment SUV coupled
with a coupe-like styling unmatched in this segment — and yet it
has all the hallmarks of an Audi. The Audi Q3 is compact, flexible
and functional and therefore is also a good option for people who
do a lot of city driving.
The growing number of Audi model series has also led to a growing
number of production sites. While the Audi Q3 is an all-new
addition to the model range, the production facility in Martorell,
Spain and is also a new addition to the Audi production network.

Body
Overview
The Audi Q3 body was developed with the focus on
lightweight design coupled with a high standard of vehicle
safety. The high quality of the materials in the Audi Q3
offers not only advantages in terms of weight reduction,
but also provides the basis for meeting the highest standards of vehicle safety.

Doors and lids
The vehicle doors are made of lightweight steel with double
sealing lines and sealed joined areas. Vehicle weight was
kept to a minimum by using a hood and rear lid made from
aluminum.

4

The body including the doors, hood and rear lid weighs
approximately 932 lb (423 kg). The body cell without doors
and lids accounts for approximately 668 lb (303 kg) of that
total.

Body structure
The main joining method used during Q3 body construction
is resistance spot welding. There are approximately 4000
spot welds in the body cell of the Q3.
High strength bonding processes are also used in body
areas with critical requirements for passive safety, comfort
and vibration reduction.

New adhesives are used for sealing and corrosion protection in addition to bonding in the Q3. For example, a
special expanding adhesive is used in the plenum chamber
which eliminates the need for additional sealing compounds.
In total, approximately 243 ft (74 m) of adhesive is used in
the body cell.

B-pillar, inner panel
The B-pillar of the Audi Q3 is partially tempered in the
shaping process. This imparts ultra-high-strength properties to the steel in the top and bottom sections and only
high-strength properties to the steel in the mid-section.
The allows the forces exerted on the vehicle body during a
side impact to be effectively absorbed.

Panorama glass sunroof
A panorama glass sunroof is standard for the Q3. It has an
opening front glass element and a fixed rear glass
element.

It is designed as an externally guided roof system. This
means the front glass panel slides over the rear glass panel.
This design provides increased headroom inside the passenger compartment.

Operating components
The operating components of the roof system are housed
in the interior light module above the rear view mirror.
The roof is operated by a four-way, two stage switch. The
roof moves in the same direction the switch is moved. The
roof can be moved to any position using the first stage of
the switch.

With the second stage, the panel moves automatically into
its end position. Pushing the switch raises the roof to the
tilt position while pulling on the switch closes it.

Bumper system
The front bumper and cover are designed to conform with
all applicable safety requirements, provide protection to
pedestrians, and be easy to repair. The supporting element
is the chrome frame around the radiator grille. The frame
is inserted into the mounting boxes of the plastic frame
during bumper assembly.

The rear bumper bracket (rebar) is made from aluminum.
The cover has two components. There is a bumper cover and
an additional lower spoiler and integrated diffuser for the
exhaust tail pipes. The pre-assembled parts are attached to
the body by guide pieces so it mounts flush to the body at
the sides.

The three part bumper cover and the front spoiler are
attached to the radiator grille. This multi-part design
allows individual components to be replaced so minor
damage can be repaired with a minimum of expense.

The wrap-around tailgate necessitated relocating some of
the tail lights to the bumper cover. These lights are integrated in the cover together with the sensors for the
optional Audi side assist and the antennas for the keyless
entry system. The parking aid sensors are attached to the
spoiler portion of the assembly.
