(from Audi Press
Release) The Audi A6: An overachiever with new strengths
The world’s most
successful business sedan just got better
New engines – High
efficiency and power
refinements and new high-tech features
A winner always builds
on his strengths: That’s why Audi has again upgraded its luxury
class A6 model. Efficient engines have been added to the drive-train
lineup, with innovative technologies cutting fuel consumption by
about 15 percent across the whole model range. An improved
suspension and new high-tech assistance system give the driver even
greater control over the car. And the new-generation MMI control
system is out-performing itself. The revamped A6 will be launched in
the German market in late summer.
It’s the sportiest and most popular business sedan on the market.
The Audi A6 is leading the Premium C pack – both in Europe and
around the world. In 2007, Audi sold about 234,000 units, giving the
A6 a 37 percent market share among its core competitors. Most of the
A6’s sold were equipped with six- or eight-cylinder engines,
permanent 4x4 quattro and a luxury assortment of optional equipment
– all evidence of the high regard Audi technologies is enjoying
Its design is emphasized by a range of bold new accents, perfectly
articulating the A6’s strong personality. The single-frame grill,
bumpers, air vents and fog lights have all gotten a facelift.
The optionally-available xenon plus, LED daytime running lights have
been redesigned as horizontal strips with 6 LEDs each. Other options
include Audi adaptive light, a dynamic cornering light system, and
the high-beam assistant that automatically switches between the high
and low beam.
An aluminum-colored molding traversing the sides emphasizes the A6’s
dynamic contour. At 4.93 meters (16.17 ft) long, 1.86 meters (6.10
ft) wide, and 1.46 meters (4.79 ft) high, little has changed in the
sedan’s generous proportions. The gentle lip on the trunk,
integrated chrome strip on the bumper, broad diffuser and straight
exhaust pipes are part and partial of the revamped rear end. The
bipartite rear lights with LED technology have also gotten a new
look: narrow and wide, they taper inward on the sedan. And there are
13 exterior colors to choose from, including five new ones.
The A6’s spacious interior with its clean and elegant contours and
perfect craftsmanship is characteristic of this luxury brand. The
rear seats are extremely comfortable and the L-shaped headrests
improve the driver’s rear view visibility. As an option, the back
seats can be fitted with a comfortable 2-seater bench. A package of
elaborate features makes sure the noise level is cut by almost half,
particularly within critical frequency ranges.
The instrument panel uses new higher-resolution graphics; and a new
frame better accentuates the display (color in the optional MMI
navigation system). Tastefully-appointed chrome trim, even on the
spokes of the steering wheel, call attention to its overall elegance
and inlays are available in either aluminum look or fine woods.
As is expected of an Audi, the interior designers have made sure all
the colors and materials match. Standard seats can be optionally
upholstered with a new material; the sport seats are available in
Valcona leather. Soft armrests on the doors increase comfort, while
the integrated headrest system reduces the danger of whiplash.
Audi is now offering an S-line sports package for the most dynamic
of drivers. The package includes enhanced performance features like
18-inch wheels and sports suspension that lowers the ride height by
30 millimeters (1.18 in). Its sporty seats, decorative inlays and
upholstery give the black-trimmed interior a feeling of even more
exclusivity and the S-line exterior package provides more drama.
Features from this Audi exclusive program are tailor-made to fit the
A6’s luxury-seeking mavericks.
One of the major strengths of the A6 lies in its broad selection of
engines: six gas and four diesels use direct fuel injection and
cutting-edge FSI, TFSI and TDI technologies in a choice of four, six
or eight cylinders. Whether stick shift, convenient tiptronic or
high-efficiency multitronic, the energy literally flows to the front
wheels, or all four wheels for that matter. Its engines are both
powerful and efficient. New measures have been introduced to
optimize engines and minimize fuel consumption without sacrificing
one ounce of driving pleasure. Fuel consumption over the whole A6
family has been lowered by about 15 percent.
The smallest gas engine is the 2.0 TFSI, a 125 kW (170 hp)
turbocharged four-cylinder unit. On the other end of the spectrum is
the 4.2 FSI, a 257 kW (350 hp) V8 engine. Audi V6 models can be
equipped with one of its two new 2.8 liter FSI engines; the 140 kW
(190 hp) or the 162 kW (220 hp). Both engines feature the innovative
Audi Valvelift System (AVS), which manages the inlet valve timing so
that there is more torque and less fuel consumption. Regardless of
which 2.8 FSI engine the A6 sedan is fitted, average fuel
consumption is only 8.2 liters per 100 kilometers (28.68 US mpg) for
the 190 hp, 6-speed manual shift or 8.4 liters per 100 kilometers
(28.00 US mpg) for the 220 hp multitronic CVT.
With its 3-liter displacement and 213 kW (290 hp) power output, the
V6 is a particularly exciting newcomer. Audi has designed the
perfect package for each one of its engine. That’s why the 3.0 TFSI
is fitted with a supercharger. From now on “T” doesn’t just stand
for turbocharged – it stands for supercharged. Supercharger
technology does not mean increased consumption – but the short
intake paths do mean instantaneous response. And it’s got full power
build-up even at low engine speeds: from 2500 1/min to 4850 1/min,
the torque curve is broad and flat at 420 Nm (309.78 lb-ft).
The 3.0 TFSI comes with tiptronic and quattro drive train. The A6
sedan accelerates from 0 to 100 km/h (62.14 mph) in 5.9 seconds and
keeps on going as it presses to its electronically-regulated maximum
speed of 250 km/h (155.34 mph). This is the kind of performance that
only an eight-cylinder engine would have been able to deliver a few
years ago. At 9.5 liters per 100 kilometers (24.76 US mpg) on the EU
cycle, the supercharged V6 is amazingly economical. The 3.0 TFSI’s
combination of dynamic performance and low consumption is one more
example of Audi’s successful efficiency strategy.
The A6 TDI engines give further evidence of just how closely Audi
has been able to align sporty performance and efficiency. Fuel is
delivered by the extremely sophisticated and quiet system of common
rails with rapid-action piezo injectors and an injection pressure of
1800 bar (26,106.79 psi). The two V6 TDI engines (2.7 TDI with 140
kW (190 hp) and 3.0 TDI with 176 kW (240 hp) have peak torques of
380 Nm (280.27 lb-ft) and 450 Nm (331.90 lb-ft), respectively.
At the lower end of the diesel program is the four-cylinder 2.0 TDI
engine, which is available in two versions: the 125 kW (170 hp),
expected in fall 2008, and the 100 kW (136 hp). The basic version is
an especially efficient e-model known as the 2.0 TDIe, which uses a
six-speed manual shift or automatic multitronic transmission to
deliver 320 Nm (236.02 lb-ft) of torque to the front wheels. With
multitronic it sprints from 0 to 100 km/h (62.14 mph) in 9.9
seconds, and continues on to a top speed of 204 km/h (126.76 mph).
Yet its average fuel consumption with a manual shift gearbox is only
5.3 liters per 100 km (44.38 US mpg), equivalent to CO2 emissions of
app. 139 grams per kilometer (224 grams per mile).
The key to achieving such exemplary values is the strategic
deployment of innovative technologies. The power steering pump
operates on demand; the alternator regenerates electrical energy
when coasting thereby reducing load off the engine. By lowering the
ride height by 20 millimeters (0.79 in) and other aerodynamic
fine-tuning, the drag coefficient has been reduced to cD = 0.28.
The transmission can be used longer in the upper two gears. Any
manual-shift A6 with Driver Information System, even the 2.0 TDIe,
can opt to have the shift indicator displayed in the instrument
panel. The icon lets the driver know which gear is most economical
under actual circumstances.
In fine-tuning the A6, two key objectives were identified –
increasing its comfort while retaining its sporty character. With
new large-diameter, front-axle shock absorbers operating within an
optimized valve system, Audi engineers were able to achieve both
goals. Every other aspect of the suspension set-up has been
improved, including the automotive spring response.
The A6 can be equipped with factory-fitted adaptive air suspension
so that the driver can vary his response and the characteristics of
the adaptive shock absorbers into three styles. High-powered engines
come equipped with larger 17-inch wheel brakes. Audi can also be
fitted with a tire pressure monitoring system, which is entirely
wear-free and maintenance-free. The customer can opt for run-flat
tires, which limit the car to 50 kilometers (31 miles) should there
be a drop in air pressure.
Audi has integrated several new high-tech assistance systems. The
new Audi side assist kicks in to help drivers when changing lanes at
speeds over 30 km/h (18.64 mph), ensuring a stress-free and superior
drive. Using radar sensors, Audi Side Assist is able to detect other
cars up to 50 meters (164.04 ft) away: a signal on the outside
mirror lights up should changing lanes pose a threat. Audi lane
assist helps keep drivers in their own lane, radar-assisted adaptive
cruise control keeps a steady distance to the vehicle ahead, and
Audi parking system advanced has a rearview camera.
Since its debut in 2002, the Audi Multi Media Interface system (MMI)
has been setting the standard for perfectly controlling any number
of functions. The A6 comes equipped with the latest MMI generation,
including the top-of-the-line MMI Navigation plus. Its basic
construction has not changed. The central control knob can still be
found on the middle console between the front seats and the
operation is still carried out using large buttons. The new joystick
capping the control knob means the MMI Navigation plus can be
operated even more intuitively.
MMI Navigation plus is an ultimate solution, pioneering in an
entirely new system generation with high-tech portfolio and
ground-breaking standards. Special features include a
CD/DVD/Navigation combination drive with a 40 GB hard drive capacity
which can be used to store MP3s and up to 5000 addresses.
With its 7-inch, high-resolution screen, the monitor on this
ultimate navigation system is truly innovative. The image is rich in
contrast and incredibly sharp even under difficult lighting
conditions. It also has an optional TV tuner that receives digital
programs (DVB-T) in perfect quality.
The new navigation system has another innovation. A new bird's eye
picture mode shows landscapes in topographical relief – in full
detail, complete with three-dimensional images of landmark
buildings. The monitor has a new operating principle: when adjusting
specific functions like air conditioning or seat heating, a pop-up
window appears at the right rather than taking over the whole
The upgraded Audi A6 will be available in German dealer showrooms as
of mid-October 2008. Starting at 34,200 Euros for the A6 2.0 TFSI
sedan, Audi’s initial list prices have remained virtually unchanged,
despite all the extensive innovations.
