Audi RS7 Sportback, which made its
debut at the 2013 North American International Auto Show 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 RS7
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 Audi RS7
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. 2014

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 Audi RS7 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. Audi RS7 Sportback (2014)
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 RS7 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.
