(from Audi Press
Release) The Audi crosslane coupé makes its debut at the Paris
Audi provides a glimpse of the future shape of design, along with
automotive and drive concepts, through its Audi crosslane coupé
concept car. This vehicle is an entirely new fusion of technology,
engineering and design, and provides pointers to the design language
of Audi’s future Q models.
With a Multimaterial Space Frame, the vehicle concept strikes out
along entirely new paths with regard to weight, costs and energy
usage over its lifecycle, and is an evolutionary stage of Audi ultra
– the lightweight construction principle from Audi.
An innovative and efficient plug-in hybrid drive based on a
1.5-liter three-cylinder TFSI and two electric motors redefines the
benchmark, with fuel consumption of only 1.1 liters per 100 km
(213.81 US mpg) and CO2 emissions of just 26 grams per km (41.84
grams per mile).
The result is a cosmopolitan vehicle that will appeal to young,
sporty customers in particular thanks to its removable roof and the
customizable services available under the Audi connect concept.
Pioneering concept: the
Multimaterial Space Frame
The Multimaterial Space
Frame of the compact Audi crosslane coupé is comprised of three
materials – aluminum, carbon fiber-reinforced polymer (CFRP), and
glass fiber-reinforced polymer (GFRP). The concept car has an
unladen weight of about 1,390 kg (3,064.43 lb), including the large
The aluminum profiles form a continuous, rigid structure around the
occupant cell. Beams beneath the front lid join the single-frame
grille, which performs a supporting function and is also made from
aluminum, with the occupant cell.
The front and rear crash structures are made from CFRP and the
supporting CFRP structures inside the occupant cell include the
inner sills, the center tunnel, the bulkhead, and the cross-members
in the floor. Surface GFRP components with partial CFRP
reinforcements complete the body concept.
Audi is convinced that the highly integrated Multimaterial Space
Frame is the right path to the future. Its weight is of the same
magnitude as a monolithic body of CFRP. It also offers convincing
advantages in terms of costs to the customer and its energy usage in
a life cycle assessment.
Innovative: dual-mode hybrid
The plug-in hybrid drive
of the Audi crosslane coupé, which is described as a dual-mode
hybrid, is as innovative as it is efficient. It comprises a
combustion engine, two electric motors and a single-stage
transmission; its system power is 130 kW (177 hp). The Audi
crosslane coupé sprints from zero to 100 km/h (62.14 mph) in 8.6
seconds, and in pure electric mode takes 9.8 seconds. The car’s top
speed is 182 km/h (113.09 mph). Its average fuel consumption is a
mere 1.1 liters per 100 km (213.81 US mpg) and it emits 26 grams per
km (41.84 grams per mile) of CO2. The lithium-ion battery has an
output of 17.4 kWh, sufficient for an operating range of around 86
km (53.44 miles) in the electric mode.
The combustion engine is a purpose-developed three-cylinder TFSI
with a displacement of 1.5 liters, delivering an output of 95 kW
(130 hp) and 200 Nm (147.51 lb-ft) of torque. The three-cylinder
engine is coupled to an electric motor (EM 1), which acts primarily
as a starter and an alternator. It develops an output of 50 kW (68
hp) and 210 Nm (154.89 lb-ft) of torque. Electrical traction is
provided by the second electric motor (EM 2) developing 85 kW (116
hp) and 250 Nm (184.39 lb-ft) of torque. The transmission makes it
possible to connect the combustion engine complete with alternator
to the remainder of the drivetrain by means of a claw clutch.
The dual-mode hybrid concept enables different operating modes. From
0 up to 55 km/h (34.18 mph), drive power is supplied solely by the
EM 2, which draws the energy it needs primarily from the battery. In
serial mode, the combustion engine and the alternator (EM 1) produce
electrical energy to support, relieve or substitute the battery
should it be discharged.
The electric mode is possible up to 130 km/h (80.78 mph). Starting
at about 55 km/h (34.18 mph) the drive system allows the TFSI engine
together with the alternator to couple to the drivetrain – in this
hybrid mode, the drive sources combine to optimize both efficiency
and performance. Above 130 km/h (80.78 mph), the three-cylinder
engine becomes the main drive source but the EM 1 can support it if
The driver of the Audi crosslane coupé can choose between the
“cruise” and “race” settings. The “cruise” mode prioritizes electric
driving. The driver does not notice either gear changes or the power
source kicking in. When the TFSI is running, its engine speed is
always adapted to the road speed – without a “rubber-band” effect.
The high efficiency of the transmission makes the dual-mode hybrid
drive especially efficient in urban traffic.
Forward-looking: exterior design
The 2+2-seater Audi
crosslane coupé is 4.21 meters long (13.81 ft), 1.88 meters wide
(6.17 ft) and 1.51 meters high (4.95 ft), with a wheelbase of 2.56
meters (8.40 ft). Its body design comes across as powerful and
striking, and it already provides a foretaste of the design language
of a future generation of Audi Q models.
The single-frame grille, which is subdivided into several segments
by struts, dominates the front end. Its prominent frame is
integrated into the Multimaterial Space Frame as a supporting
element. This solution symbolizes the philosophy behind the Audi
crosslane coupé: a totally new fusion of basic concept, technology
The trapezoidal headlights use Audi Matrix LED headlight technology.
Small, individually controllable light-emitting diodes generate all
lighting functions, and microreflectors enable their precise
positioning. The bumper incorporates large, mainly smooth-surfaced
air intakes. Through two narrow openings in the front lid it is
possible to glimpse the upper aluminum members of the Multimaterial
Along the sides, the horizontal edges are the dominant feature above
the wheels. The low greenhouse tapers into a very flat C-post,
emphasizing the coupé-like character of the Audi crosslane coupé.
The doors extend a long way down thanks to the space frame design,
which allows very low sills. The doors open to reveal the aluminum
structures of the Multimaterial Space Frame.
The tail lights are a variation on the motif of the headlights; the
trunk lid seam divides them each into two segments. The bumper, the
lower section of which is made from CFRP, incorporates an aluminum
diffuser that extends quite some way up. The roof element comprises
two CFRP shells and weighs slightly less than ten kilograms (22.05
lb). The driver and front passenger can unlatch it by an electric
drive, remove it from the body structure and fit it over the trunk.
The trunk forms a
separate pan within the body structure; it is attached to the backs
of the rear seats, which are separate from the seat cushions. At the
press of a button, the entire unit travels about 40 cm (15.75 in)
forward electrically; this is how the latched roof reaches its end
position, in which it protects the luggage. At the same time, the
level surface under the trunk becomes accessible, and it offers a
flat storage space for dirty or wet objects.
The driver and front passenger sit on electrically adjustable sport
seats with integrated head restraints, the shells of which are made
from CFRP. The center console integrates a large selector lever,
which is electrically extended when the car is started; it is used
to control the hybrid drive. The spokes of the steering wheel
incorporate control surfaces for the thumbs, which the driver can
use to carry out most functions. These can also be controlled just
as intuitively from a large touchpad on the center console.
The low dashboard is very clearly turned towards the driver. The air
conditioning controls incorporate miniature displays. The virtual
displays in the instrument cluster can be toggled between two
different levels, and a powermeter visualizes the drive system’s
The Audi crosslane coupé introduces new online services under the
key word Audi connect. Its passengers are always connected to the
Internet community – via Twitter, Facebook or by sending photos and
videos recorded on the road. A completely new feature is the “Escape
Manager” – a program passengers can use to review and comment on the
routes they are driving for their friends.
Geometric clarity: interior design
The interior design of
the Audi crosslane coupé continues the design language of the
exterior in the geometrical clarity of its basic shapes; instrument
covers and the grilles on the air nozzles, for example, take up the
trapezoidal theme. The narrow gap dimensions and three-dimensional
surfaces reflect Audi’s uncompromisingly high quality standards.
The dominant interior material of the Audi crosslane coupé is CFRP,
which is used in a number of different variations. On the dashboard
cowl, for instance, the composite fibers are all aligned in a single
direction; this unidirectional arrangement is a new departure in the
automotive sector. The CFRP parts are slightly lighter in color in
some areas and darker in others, an effect achieved by different
clear coat applications.
The aluminum elements, too, are used in a subtly differentiated way.
Most of them are machine-polished, but the air nozzles use a black
anodized light alloy. The vehicle floor is made from glass
fiber-reinforced polymer (GFRP) incorporating sections of a new
material: Thick cords are woven with rubber threads to form a
In their leather selections, Audi designers also employed various
material grades. The most widely used grade is soft semi-aniline
leather. Velvet leather in black provides an enlivening contrast. It
has a robust, slightly coarse surface reminiscent of suede.
