Audi
TT Offroad Concept
The
Audi TT offroad concept breaks the mold, combining the sportiness of a coupe
with the lifestyle and utility of a compact SUV. The four-door model, which
Audi has presented at the 2014 Beijing International Automobile Exhibition,
adds an entirely new expression to the Audi design language.
The
plug-in hybrid drive in the Audi TT offroad concept delivers 408 hp of
system output and 650 Nm of system torque. The show car
accelerates from 0 to 100 km/h in 5.2 seconds and reaches the
electronically governed top speed of 250 km/h without any trouble.
It consumes just 1.9 liters of fuel per 100 kilometers, a CO2
equivalent of 45 grams per kilometer. The
Audi TT offroad concept can drive over 50 kilometers solely on
electric power and thus with zero local emissions, and has a total range of up
to 880 kilometers.
The
combustion engine is a 2.0 TFSI producing 292 hp and 380 Nm of torque. The two-liter, four-cylinder unit with the large turbocharger
is packed with Audi's potent efficiency technology. At part load, indirect
injection supplements gasoline direct injection for lower fuel consumption. The
exhaust manifold is integrated into the cylinder head - the foundation for the
high-performance thermal management system.
A
separating clutch links the transverse 2.0 TFSI to an electric motor producing
40 kW and 220 Nm of torque. The slim, disc-shaped electric motor
is integrated into the six-speed e-S tronic. The dual-clutch transmissions
sends the torque to the front wheels. Mounted on the rear axle of the Audi TT
offroad concept is a second electric motor independent of this drive unit. This
produces a maximum of 85 kW and 270 Nm. In
front of the rear axle is a liquid-cooled, lithium-ion battery comprising eight
modules. It contributes to the balanced 54:46 weight distribution between the
front and rear axles and to the low center of gravity. The battery stores up to
12 kWh of energy, enough for an electric range of 50 kilometers.
An Audi wall box, which manages the energy feed conveniently and intelligently
and can deal with a variety of voltages and outlets, is used for stationary
charging.
The
show car is also designed for use with Audi Wireless Charging technology for
contactless inductive charging. The infrastructure side - a plate with a coil
and an inverter (AC/AC converter) - is placed on the parking spot of the Audi
TT offroad concept and connected to the power grid. The charging process begins
automatically when the car drives onto the plate. The alternating magnetic
field of the infrastructure side induces a 3.3 kW alternating current across
the air gap in the secondary coil, which is integrated into the vehicle. The
current is inverted and fed into the electrical system. Charging
stops automatically when the battery is fully charged. It takes about as long
as charging via a cable, and the driver can interrupt the process at any time.
The Audi Wireless Charging technology is more than 90 percent efficient, and is
not affected by weather factors such as rain, snow or ice. The alternating
field, which is only generated when a car is on the plate, is not harmful for
people or animals.
The
Audi TT offroad concept shows its strong character on any road surface and in
any terrain. On asphalt the show car is sporty and composed, and it can easily
handle light terrain thanks to its high ground clearance, short overhangs and
e-tron quattro all-wheel drive. 255/40-series tires are mounted on 21-inch
wheels, whose delicate five-arm design draws on the look of the Audi e-tron
models. Dark trim provides contrast.
Many
of the components of the McPherson front suspension are made of aluminum; the
four-link rear axle handles longitudinal and transverse forces separately. The
ratio of the progressive steering changes with the steering input. The Audi
drive select system allows the driver to modify the function of various
technical modules in multiple steps.
The
Audi TT offroad concept show car features two Audi driver assistance systems
that are almost ready for production: the intersection assistant and online
traffic light information technology. The intersection assistant aims to help
to avoid side-impact collisions, or reduce their severity, where lanes merge
and at intersections. Radar sensors and a wide-angle video camera scan zones to
the front and sides of the car. If the system detects a vehicle approaching
from the side and assesses it to be critical, graduated warnings are displayed
in the Audi virtual cockpit.
4.39
meters long, 1.85 meters wide and a wheelbase of 2.63 meters - in these dimensions the Audi TT offroad concept resembles today's
compact SUV, the Audi Q3. At 1.53 meters tall, however, it is 8
centimeters shorter, making its sporty character obvious at first
glance. The Sonora Yellow outer skin appears to have been modeled from a solid
block; the interplay of the clearly drawn lines and the muscularly taut
surfaces produces a highly dramatic design. It uses the design language of the
Audi TT, but places its elements in a new context.
Horizontal
lines dominate at the front of the new Audi TT offroad concept. The broad
Singleframe grille bearing the four rings is sculpturally embedded in the body.
Two subtle indents in the lower region make the grille appear lighter. Narrow
louvers in the grille insert form a structure typical of the Audi e-tron
models.
The
large air inlets below the Matrix LED headlights are framed in sharp edges and
structured with louvers. A third, flat inlet below the grille joins them
together. Inside is a blade that increases downforce on the front axle and
makes the front of the Audi TT offroad concept appear even wider.
The
interior of the Audi TT offroad concept offers space for four. The rear seat
can accommodate two adults comfortably. The slim sport seats with integrated
head restraints ensure lateral hold. The side bolsters of the front seats are
very strongly contoured.
The
show car is equipped with three Audi Smart Displays. The fast tablets serve as
a mobile infotainment system for use inside and outside of the car. From DVD or
TV streaming to controlling the radio or navigation planning, the Audi Smart
Display is extremely versatile. One click on the "more" button in the
start menu establishes an Internet connection via Audi connect at LTE speed.
The user now has access to all of the functions of the Android operating
system, from browsing with Google Chrome to visiting the Google Play store.
