Audi A1 Sportback Concept

At the 2008 Paris Motor Show Audi has unveiled the A1 Sportback Concept, a five-door compact vehicle with a hybrid powertrain. The dynamic design is an evolution of the 2007 three-door Audi A1 project quattro concept.

Audi A1 Sportback Concept - Design renderingThe Audi A1 Sportback Concept is 3.99-meter long and
1.75-meter wide and combines a dynamic styling with
a hybrid powertrain.

This consists of a 1.4 liter TFSI engine developing 150 hp and a 20 kW (27 hp) electric motor integrated in the drive train which can deliver additional torque when accelerating or drive the car in pure electric mode for up to 100km.

From the official Press Release:

Exterior Design

Audi A1 Sportback Concept - Design renderingThe styling of the five-door
concept vehicle is a consistent development of the three-door study, the Audi
A1 project quattro from the year 2007. Surfaces and lines are tauter and
more masculine.

Like the three-door version, the body of the four-door Audi A1 Sportback concept
makes optimum use of the small road surface area available to a vehicle from the
premium compact class.

Measuring 3.99 m long (13.09 ft) and 1.75 m wide
(5.74 ft) with a wheelbase of 2.46 m (8.07 ft) and a height of 1.40 meters (4.59 ft), it succeeds in combining sporty
looks with impressive economy of space thanks to its short overhangs.

transverse installation of the engine also has a significant role to play in this

The basic proportions, with a high vehicle body and a flat window area bordered
by a coupe-like roof line, produce a virtually classic look for a vehicle bearing the
four rings.

The rear end is rounded off by a two-part spoiler with a striking centre
groove, integrated into the rear window.

The side view presents another typical coupe attribute in the form of doors
with frameless windows and a glass-covered and thus homogeneously integrated

The bold segmentation of the study’s side paneling with its gently rising
shoulder line accentuates the styling.

finish is a new interpretation of a trademark feature of the current Audi

Here, the prominent double lines continue around the entire vehicle as a
curvaceous band that links the front end – from which it seems to emerge – with
the vehicle’s tail, which rises to create a slightly wedge-shaped effect.

The aerodynamically designed single-frame grille indicates the sporty charachter
of the study, which is further emphasized by the flared fenders – a tribute to the
legendary Ur-quattro design and the current Audi RS 6.

Audi A1 Sportback ConceptThe design of the three-dimensional main headlights in innovative LED
is especially eye-catching.

The completely new styling underlines yet
again the amount of freedom that this technology has afforded to designers. All
light functions – low-beam and high-beam headlights, daytime running lights and
turn indicators – have been located in one flat housing, in concentrically arranged,
parallel and squared-off strips.

The layout, with light segments of varying sizes – the low beam taking up most
space – completely changes the character of the front section, the “face” of the
A1 Sportback concept.

The rear lights continue this theme and combine the function of tail and
brake lights, turn indicators, reversing and rear fog lights.

The interplay of acute and obtuse angles and the clear and colored glass areas create a particularly dynamic look. A large-dimensioned, transparent cover
over the entire width of the vehicle additionally combines both light units and
emphasizes the horizontal design of the rear.

Interior Design

Audi A1 Sportback Concept - InteriorThe interior features four individual seats and a
spacious and tidy appearance.

The curved, wraparound
combines the doors and the sporty cockpit into one single unit. The
dashboard and center console are designed entirely around the driver.

Details such as the turbine-look air vents and air
conditioning controls seem to be straight out of a jet plane.

Here the air
flow direction and volume can be regulated simply by turning or
pressing the control button in the centre of the vent.

The center console accommodates the integrated selector lever, only extended in
drive select dynamic mode, the start/stop button for the engine, the switch for
Audi drive select and the armrest with an integrated mobile phone pocket.

The sporty seats with integrated head restraints offer levels of comfort and
ergonomics that far exceed the customary standards in the sub-compact class and
live up to the expectations of a typical Audi. A transparent, mesh-like fabric
covers the lightweight seat apertures, which further accentuates the airiness of the

The materials used for the interior trim appeal with their high-class looks and feel.
The contrasting color scheme for the interior – white and red – emphasizes the
feeling of spaciousness.

The infotainment system is the the second generation of Audi mobile device: the driver can use his mobile phone as a car phone, address database, navigation system and
audio/video player.

At the same time it can be used as a control unit for numerous
vehicle systems. Several phones that are
suitable for these functions are already available from various manufacturers.

The MMI control unit features are fixed-function hardkeys for the
Navigation, Telephone, Car and Media basic menus, grouped
around the central rotary pushbutton. Four additional, backlit
softkeys have variable functions which change within the individual menus.Audi A1 Sportback Concept


Audi A1 Sportback ConceptThe car is powered by a 1.4-litre
TFSI engine developing 110 kW (150 hp), whose power is directed to the front
wheels by means of the S tronic dual-clutch transmission.

A 20 kW (27 hp)
electric motor integrated in the drive train is able to deliver up to an additional
150 Nm of torque (110.63 lb-ft) when the vehicle is accelerating.

The electric motor is furthermore capable of powering the vehicle alone for zero-emission
driving in residential areas, for instance.

The capacity of the lithium-ion
batteries gives the vehicle a range of up to 100 km (62.14 miles) in pure electric
; the motor can be recharged from any power socket.

The automatic
start/stop facility, energy regeneration and phases of purely electrical operation
reduce the fuel consumption and emissions of the Audi A1 Sportback concept by
almost 30 percent compared to when it is running on the combustion engine

Despite its sporty performance, with acceleration of 0 to 100 km/h
(62.14 mph) in 7.9 seconds and a top speed of 200 km/h (124.27 mph), the Audi
A1 Sportback concept requires only 3.9 liters of premium fuel per 100 km
(60.31 US mpg); CO2 emissions are an efficient 92 g/km (148.06 g/mile).


The chassis design consists of a McPherson front
suspension and four-link independent rear suspension, which
splits the functions for absorbing longitudinal and lateral forces, allowing for a
high level of lateral rigidity ans well as a great degree of longitudinal flexibility to
improve ride comfort.

The 18-inch wheels are combined with 225/35 R18 tires. The braking system has 312 mm diameter front discs.

The shock absorbers use a a magneto-rheological fluid whose qualities can be controlled by means of an
electromagnetic field. This effect enables the damping characteristic to be
influenced electronically at will by applying a voltage to the electromagnets.

Among the additional controls are the new active, ESP-controlled front differential lock, that helps in distributing the torque according to the driving situation and the electromechanical steering with speed-sensitive power.
