Default Audi re-illuminates Sport Quattro with Laserlight concept for CES

From AB









World premiere at 2014 CES in Las Vegas: The Audi Sport quattro
laserlight concept car

- Dynamic coupe has powerful plug-in hybrid drive
- Prof. Dr. Ulrich Hackenberg, Member of the Board of AUDI AG,
Technical Development: "This show car embodies our engineering
competence and shows cutting-edge electronic features such as
high-performance laser-light headlights."

Dynamic design, immense power and new electronic features: Audi is
presenting a fascinating technology concept car at the Consumer
Electronics Show (CES) from January 6 to 10, 2014 in Las Vegas, USA.
The Audi Sport quattro laserlight concept is reminiscent of the
classic Sport quattro of 1983 while pointing towards the future – with
the latest of the brand's technologies in plug-in hybrid drives, user
control and display interfaces and lighting technology.

"The new show car demonstrates technical 'Vorsprung' on many
levels," says Prof. Dr. Ulrich Hackenberg. "On-board this
car we have e-tron technology with 515 kW of power and 2.5 l/100 km
(94.09 US mpg) fuel economy; laser headlights that leave all previous
systems in the dark with its higher performance as well as new display
and operating systems with cutting-edge electronic performance. We are
showing the future of Audi here."

The coupe, a new evolutionary stage of the Sport quattro concept,
painted in the color Plasma Red, combines the power of the historic
Sport quattro with emotional elegance. Its body is tautly set over its
large wheels. The overhangs are short, and the car's proportions show
a sporty balance. With a wheelbase of 2,784 mm (109.61 in), it is
4,602 mm (181.18 in) long. At a width of 1,964 mm (77.32 in), the
two-door model is very wide, and it is just 1,386 mm (54.57 in) tall,
which is exceptionally low.

In the dual headlights, a typical quattro feature, Audi is
demonstrating the future of lighting technology by combining matrix
LED and laser light technologies. Two low-profile trapezoidal elements
are visible within the headlights – the outer one generates the low
beam light using matrix LEDs and an aperture mask, while the inner
element produces laser light for high-beam functionality.

The powerful laser diodes are significantly smaller than LED diodes;
they are only a few microns in diameter. Illuminating the road for a
distance of nearly 500 meters (1,640 ft), the laser high-beam light
has approximately twice the lighting range and three times the
luminosity of LED high beam lights. In this future technology, Audi is
once again demonstrating its leadership role in automotive lighting
technology with a system that will also be used on the race track in
the 2014 R18 e-tron quattro.

The angular, swept-back C pillars of the Audi Sport quattro laserlight
concept car and the blisters above the fenders are other design
elements reminiscent of the classic Sport quattro. The broad shoulders
of the body were reinterpreted and intensively sculpted to convey even
greater dynamism. Throughout the car, sharp contours frame muscular
surfaces – the interplay between convex and concave curvatures defines
the athletic character of the coupe.

The hexagonal single-frame grille also offers an outlook on future
design of the sporty production models. The lower section is nearly
vertical, while the upper follows the contour of the hood; the screen
insert is a typical solution from car racing. The low grille
emphasizes the show car's width. Two large, vertical blades divide
each of the large air inlets; their form is repeated in the creases of
the hood. The splitter, which is made of carbon fiber reinforced
polymer (CFRP), is shifted far to the front, as on a race car.

The combination of a swept-back glass cabin and broad shoulders
defines the proportions at the rear. Another defining element at the
rear of the show car is the CFRP diffuser, which extends upward
significantly. Its upper section is honeycombed, while its lower
section houses two large, oval tailpipes. The tail lights, which are
backed by a black CFRP panel, are rectangular in form – another
quattro reference. The luggage space, which is reinforced by a large
cross bar stiffener, offers 300 liters (10.59 cu ft) of cargo
capacity.

Precise design details round out the dynamic look of the Audi Sport
quattro laserlight concept. The sill extensions are made of CFRP, the
door handles electrically extend from the door when they detect the
approach of a hand. The center locking wheels have a five twin-spoke
design.

Lightweight design made visible: the interior
In its generously cut interior, the elegant sporty styling of the show
car is continued with dark gray colors and clean lines. The interior
design and material selections demonstrate the Audi philosophy of
lightweight design. The slender instrument panel is reminiscent of the
wing of a sailplane. The supporting structure of the interior is a
carbon shell that also serves as a storage compartment in the doors.

A line of trim beneath the windshield wraps around the driver and
front passenger and integrates functions such as the inside door
handles. The folding race car shell seats with their high lateral
supports and integrated head restraints, together with the two rear
seats, provide space for four persons. The climate controls are
integrated in the air nozzles; a single element is used to control the
intensity, temperature and volume of the air stream. In addition to
showing climate control settings, the slim display at the centers of
the air nozzles also shows media data.

New solutions: displays and controls
The interior of the Audi Sport quattro laserlight concept focuses very
much on the driver. Even the multifunction sport steering wheel points
the way towards future sporty production solutions. It has two buttons
which the driver can use to control the hybrid drive, a red start-stop
button, a button for the Audi drive select vehicle handling system and
a "View" button to control the Audi virtual cockpit.

All key information is shown on the large Audi TFT display in
high-resolution, three-dimensional graphics; a cutting-edge Tegra 30
processor from Audi partner Nvidia processes the graphics. The driver
can switch between different modes. For example, in the MMI mode the
dominant display elements include the navigation map and media lists,
while in the Classic view the speedometer appears in the foreground.

Nearly all functions of the Audi Sport quattro laserlight concept can
be controlled from the further developed MMI terminal that is mounted
on the center console over the tunnel. Its large rotary pushbutton,
which also serves as a touchpad, can be pushed in four directions, and
it is surrounded on three sides by four buttons – for the main menu,
submenus, options and a back function.

The new user interface has a menu structure whose intuitive layout is
similar to that of a smart phone. All frequently used functions can be
accessed lightning fast. For most inputs, just a few steps are needed
thanks to a new free text search feature; generally just four
characters suffice for a navigation address. The driver can quickly
scroll through lists or zoom the map image using multitouch gestures
on the touchpad. Voice control functionality has also been intensively
further developed.

Powerful and highly efficient: the drive system
The plug-in hybrid drive gives the Audi Sport quattro laserlight
concept fascinating dynamic performance. Its system output is 515 kW
(700 hp), and its system torque is 800 Nm (590.05 lb-ft). Power flows
via a modified eight-speed tiptronic to the quattro drivetrain, which
features a sport differential at the rear axle. The show car's
combined fuel consumption, based on the applicable fuel economy
standard, is just 2.5 liters of fuel per 100 km (94.09 US mpg) – which
equates to CO2 emissions of 59 g/km (94.95 g/mile).

The combustion engine is a four-liter V8 with biturbo charging; it
produces 412 kW (560 hp) of power and 700 Nm (516.29 lb-ft) of torque.
The cylinder on demand (COD) system, which deactivates four cylinders
under part load and a start-stop system make the sonorous
eight-cylinder engine very efficient. Located between the 4.0 TFSI and
the transmission is a disc-shaped electric motor that produces 110 kW
and 400 Nm (295.02 lb-ft). It draws its drive energy from a
lithium-ion battery at the rear, which stores 14.1 kWh of energy –
enough for up to 50 km (31.07 miles) of all-electric driving. An Audi
wallbox that is used for charging provides for optimal energy
transfer.

An intelligent management system controls the interplay of engine and
motor on demand. The driver can switch between three different modes.
In EV mode, just the electric motor operates; its high torque propels
the show car with plenty of power – even outside of the city. The
active accelerator pedal indicates the transition to Hybrid mode to
the driver – by a change in pedal resistance; this is done so that the
driver can intentionally influence the mode selection.

The Hybrid mode aims at optimal fuel-savings in the interplay between
the TFSI and the electric motor, and environmental and route data are
utilized here. The driver can choose the Hold and Charge modes in the
MMI to influence the operating strategy, e.g. if the driver wants to
ensure that sufficient electrical energy is available for the final
kilometers to the destination. The Audi drive select dynamic vehicle
handling system offers even more control options – individual driving
profiles are set up for different levels of regenerative braking.

In Sport mode, the operating strategy configures the drive system for
maximum power. When the V8 and electric motor are boosting, the Audi
Sport quattro laserlight concept accelerates from a standstill to 100
km/h (62.14 mph) in 3.7 seconds and can reach a top speed of 305 km/h
(189.52 mph).

Body and chassis
A lightweight design strategy also plays a major role in the car's
dynamic performance. A combination of ultra high-strength steel sheet
and structural elements of cast aluminum is used in the occupant cell.
The doors and fenders are made of aluminum, and the roof, engine hood
and rear hatch are made of CFRP. This results in an unladen weight of
just 1,850 kilograms (4,078.55 lb), including the large battery pack.

The front suspension is comprised of five links per wheel, while the
rear suspension is based on the self-tracking trapezoidal link
principle of Audi, which guarantees dynamic performance and stability.
Stiff tuning of the springs and shock absorbers make the Audi Sport
quattro laserlight concept hold tightly to the road, while Audi drive
select makes the driving experience even more multifaceted. The
dynamic steering system varies the steering ratio as a function of
driving speed. The brake calipers grip large, carbon fiber-ceramic
brake discs, and the tire size is 285/30 R 21.
