The Audi RS 7 Sportback made its debut at the North American
International Auto Show 2013
Detroit - Audi is
expanding its RS model lineup: The RS 7 Sportback, which is making its
debut at the North American International Auto Show 2013 in Detroit,
stands for dynamics at their most beautiful.
The large five-door
coupe uses a 4.0 TFSI engine producing 412 kW (560 hp). The sprint from
zero to 100 km/h (62.14 mph) takes just 3.9 seconds, and the speed
governor can be deactivated upon customer request to permit a top speed
of up to 305 km/h (189.52 mph). Despite this superior performance, the
Audi RS 7 Sportback consumes on average just 9.8 liters of fuel per 100
km (24.00 US mpg).
Aesthetic design,
innovative technology and impressive sportiness: The RS 7 Sportback, the
large five-door coupe from Audi, combines many strengths to produce a
fascinating character. Its strong heart is the 4.0 TFSI, which takes
Audi’s downsizing strategy to the high-end category. The twin-turbo V8
displaces 3,993 cc and develops awesome power, with 412 kW (560 hp)
available between 5,700 and 6,700 rpm. A constant 700 Nm (516.29 lb-ft)
of torque are available between 1,750 and 5,500 rpm.
Because the high-revving four-liter engine
has been rigorously designed for low load-change and flow losses, it
develops this power quickly and spontaneously. The cylinder heads have
the exhaust side on the inside and the intake side on the outside. The
two twin-scroll turbochargers, which produce up to 1.2 bars of relative
boost pressure, are located together with the intercooler in the inside
V of the cylinder banks. Consequently, the gas paths are very short and
response very good. The RS-specific engine management and unthrottled
intake system also contribute to the dynamic character of the twin-turbo
V8. Switchable flaps in the exhaust system make the engine sound even
fuller at the push of a button or under strong acceleration. Audi also
offers an optional sport exhaust system.
The RS 7 Sportback sprints from 0 to 100
km/h (62.14 mph) in just 3.9 seconds. Audi limits the top speed in the
standard configuration to 250 km/h (155.34 mph). Top speed with the
optional dynamic package is 280 km/h (173.98 mph) and 305 km/h (189.52
mph) with the dynamic package plus.
Yet the new top model of the model series
consumes on average just 9.8 liters of fuel per 100 km (24.00 US mpg).
This top value is due in part to the standard start-stop system and
innovative thermal management.
The most innovative efficiency technology
in the new Audi RS 7 Sportback is the cylinder on demand (COD) system.
At low to medium loads and engine speeds, it deactivates cylinders 2, 3,
5 and 8 by closing their valves via electromechanical actuators. The 4.0
TFSI then runs as a four-cylinder engine until the driver accelerates
more strongly again. The operating points in the active cylinders are
displaced toward higher loads, increasing efficiency.
All of these operations take just a few
hundredths of a second and occur so smoothly and quickly that they can
hardly be felt or heard. Active engine bearings, another high-end
solution from Audi, use out-of-phase counter-oscillations to compensate
for the slight vibrations that occur during four-cylinder operation. The
COD technology reduces NEDC fuel consumption by roughly five percent,
and even greater savings of approximately 10 percent are possible when
driving at moderate speeds.
The standard eight-speed tiptronic is
specially tuned to the sporty character of the Audi RS 7 Sportback.
Drivers can choose between the modes D and S or change gears themselves
using the shift paddles on the steering wheel or the selector lever,
which sports a unique RS design. While the lower gears of the tiptronic
are closely spaced for sporty response, eighth gear is tall like an
overdrive to reduce fuel consumption.
The Audi RS 7 Sportback comes standard
with quattro permanent all-wheel drive for its decisive advantage in
traction and driving safety compared with its two-wheel-drive
competitors. At the heart of the quattro system is a center differential
with a high locking rate and a separate oil cooler to regulate its
temperature. It distributes the power as needed within a wide range
between the front and rear axles. In the standard configuration, 60
percent flows to the rear and 40 percent to the front.
