Dynamic performance where the sky's the limit - Audi introduces the
Audi RS5 Cabriolet. The four-seat convertible with a cloth soft top
entices with a unique combination of elegance and power. Its 4.2 FSI, a
high-revving naturally aspirated V8 engine, outputs 331 kW (450 hp). It
accelerates the high-performance sports car from zero to 100 km/h (62.14
mph) in 4.9 seconds.
Exterior design
In
the Audi RS5 Cabriolet, Audi dynamics takes on an especially beautiful
form in the car's flowing side profile with perfectly balanced
proportions and sharp details. A frame in matt aluminum look surrounds
the hexagonal single-frame grille; its honeycomb grille insert that
sports an RS5 logo shines in anthracite. Wedge-shaped headlights with
wave-like lower edges illuminate with xenon plus lamps and LED strips
that form the daytime running lights. Large air intakes are embedded in
the distinctively shaped front apron whose ends run out into splitter
edges.
Sill add-ons and wheel housing extensions dominate the
car's appearance in side profile; the tornado line that defines the
shoulder of the Audi RS5 Cabriolet was drawn to look especially sharp.
The door mirror housings have an aluminum look, while the surface of the
windshield frame and the decorative trim strips of the window channels
and the soft top box cover are made of matt anodized aluminum.
The
lightweight textile roof of the Audi RS5 Cabriolet spans over the
generously proportioned interior space like a low curved dome; a special
foam layer in the roof delivers high acoustic comfort. At the press of a
button, the soft top opens and closes fully automatically in 15 seconds
and 17 seconds respectively - even when driving at speeds of up to 50
km/h (31.07 mph).
When open, it hardly affects the size of the spacious luggage
compartment - it only requires 60 liters (2.12 cu ft) of its 380 liters
(13.42 cu ft) total volume. The split rear seatbacks can be folded over
individually, and a load-through hatch from the trunk to the rear
seating area improves variability. Special reinforcements contribute to
the convertible body's high rigidity, and aluminum front fenders
compensate for some of the added weight of the reinforcements.
Elegant
LED light strips illuminate in the taillights, which operate without
any conventional incandescent lamps. Like the lights, the rear bumper
was also redesigned; its diffuser is now much higher, and a honeycomb
screen insert encloses the two large elliptical tailpipes of the exhaust
system. On the trunk lid there is a subtle matt carbon spoiler lip for
more downforce; it may be painted in the exterior color as an option.
The
Audi RS5 Cabriolet measures 4,649 mm (15.25 ft) long, 1,860 mm (6.10
ft) wide and 1,380 mm (4.53 ft) high, and its wheelbase is 2,751 mm
(9.03 ft). Eight exterior colors are available - a monochrome color,
four metallic and pearl effect colors and three crystal effect paints.
The soft top is available in black, gray, red or brown. As options, Audi
can install a styling package in matt aluminum as well as an engine
compartment design package that uses carbon fiber-reinforced polymer
(CFRP) materials. The car's drag coefficient is 0.34; underbody panels
make a significant contribution towards aerodynamic refinement.
Interior
A
typical RS5 highlight is its three-spoke steering wheel with
flat-bottomed rim that is trimmed in perforated leather. The
multifunction keys are intuitive, as are all other controls in the Audi
RS5 Cabriolet. The terminal of the optional MMI navigation plus system,
for example, only requires six permanent keys for the main menus, and
just a single button control suffices for Audi drive select. White
numerals on black dials provide a strong contrast and are easy to read.
Sport-oriented drivers will find a lap timer for lap times and an oil
temperature gauge in the driver information system.
The sport
seats have power adjustments, high side panels for optimal lateral
support, integrated head restraints, a lumbar support and a pull-out
thigh support. They are upholstered in a combination of leather and
Alcantara or in the optional black or lunar silver Fine Nappa leather.
All leather types are pigmented to inhibit heating by sunlight. Seat
alternatives are manually adjustable bucket seats or climate-controlled
comfort seats with a ventilation feature.
The interior of the Audi
RS5 Cabriolet is styled in black, and the inner soft top liner can be
ordered in the optional color star silver. Fine chrome highlights,
understated high-gloss black trim and carbon inlays underscore the car's
dynamic appearance. Upon request, Audi can deliver the inlays in
Aluminum Race, piano finish black, matt brushed aluminum or stainless
steel mesh at no additional cost.
There are RS logos on the backs
of the seats, the aluminum inlays in the door sill plates, the steering
wheel, the tachometer and the gear selector grip of the seven-speed S
tronic. The inside door handles consist of two slender ribs, and the
pedals and many other controls glisten in aluminum look. The Audi
exclusive program offers many other customizing options.
Engine
Propulsive
power for the Audi RS5 Cabriolet is supplied by a high-revving,
naturally aspirated V8 engine with FSI direct injection. From its 4,163
cc of engine displacement, it outputs 331 kW (450 hp) at 8,250 rpm and
produces a maximum torque of 430 Nm (317.15 lb-ft) between 4,000 and
6,000 rpm. The 4.2 FSI with red painted cylinder head covers that is
manually assembled in the Hungarian plant in Győr achieves a specific
power output of 79.5 kW (108.1 hp) per liter engine displacement; each
hp only needs to move 4.267 kg (9.41 lb) of vehicle weight. The
long-stroke engine with its aluminum crankcase breathes freely; flaps in
the exhaust tailpipes vary the sonorous acoustic backdrop. As an
option, Audi can deliver a sport exhaust system with black tailpipe
trim.
The Audi RS5 Cabriolet rockets from a standstill to 100 km/h
(62.14 mph) in 4.9 seconds. The car's top speed is limited to 250 km/h
(155.34 mph); at customer request, Audi can boost this to 280 km/h
(173.98 mph). The powerful V8 has a combined fuel consumption of 10.9
l/100 km (21.58 US mpg). Its cylinder liners and chain drive are
optimized for minimal friction, and the oil pump is only driven as
needed.
Power transmission
Dual-clutch
transmissions like the seven-speed S tronic of the Audi RS5 Cabriolet
are distinguished by a high level of efficiency, which is further
improved in this model by the long ratio of the highest gear. Shifts are
performed so quickly and smoothly by alternating the clutches that they
are hardly perceptible. The driver can have the seven-speed S tronic
shift automatically in the D or S program, or he/she can manually shift
with the gearshift lever or the paddles on the steering wheel. The
Launch Control function is a useful drive-off assistant for the race
course. It enables an optimal start by letting out the clutch at an
ideal drive-off engine speed.
The quattro permanent all-wheel
drive system gives the Audi RS5 Cabriolet a decisive advantage in
traction and stability. Its technological centerpiece, the crown-gear
center differential, is lightweight and compact. In normal driving
operation, it distributes torque between the front and rear axles at a
40:60 ratio; if necessary, it can direct up to 70 percent to the front
or a maximum of 85 percent to the rear. Torque vectoring - an
intelligent software solution - completes the center differential's work
tasks.
If a wheel at the inside of a curve begins to lose its
grip when cornering at speed, it is braked slightly before any slip
occurs - this keeps the Audi RS5 Cabriolet neutral for an exceptionally
long time in extreme driving conditions.
As an option, Audi can
install a sport differential that actively distributes power between the
rear wheels via two superposition gears. A perfect supplement to the
quattro drivetrain, it presses the Audi RS5 Cabriolet into the curve at
the handling limits, counteracting any tendency to oversteer or
understeer right from the outset.
Chassis
The
chassis of the four-seat convertible exhibits a high level of technical
complexity. Many components of the five-link front suspension and the
self-tracking trapezoidal-link rear suspension are made of aluminum. The
speed-dependent power steering system utilizes an electromechanical
drive unit; it provides direct and sensitive steering feedback and is
highly efficient. The body is 20 mm (0.79 in) lower than that of the Audi A5 Cabriolet;
its mounts are stiffer, and its anti-roll bars are larger and stronger.
The standard wheels are forged aluminum wheels in machine-polished
ten-spoke design, size 9 J x 19 with 265/35 tires; 20-inch wheels in
three attractive designs with tires in 275/30 format are available as
options.
The brake system employs internally ventilated and
perforated discs in a weight-saving wave design; the front discs are 365
mm (14.37 in) in diameter. The wave-shaped outer contour of the
friction rings reduces unsprung mass by a total of about three kilograms
(6.61 lb). Pins are used to join the discs to the aluminum brake pots -
a concept adopted from motorsport. The brake calipers are painted
black; the front brakes operate with eight pistons each. The ESC
stabilization system has a Sport mode and can also be completely
deactivated. Audi can deliver the car with carbon fiber-reinforced
ceramic front discs and six-piston calipers as an option.
Audi
drive select is a standard feature in the Audi RS5 Cabriolet. The driver
can use this function to vary the characteristics of the steering
system, seven-speed S tronic, throttle valves and exhaust system sound
flaps to one of the modes comfort, auto or dynamic; if an MMI navigation
system is installed, the 'individual' mode is also offered.
The
sport differential, adaptive cruise control and dynamic steering - whose
gear ratio can be varied by nearly 100 percent as a function of vehicle
speed - can also be incorporated into the system.
Another option
that is controlled by Audi drive select is sport suspension plus with
Dynamic Ride Control (DRC) - a purely mechanical system that operates
without any delays. Each pair of diagonally opposing shock absorbers is
interconnected via hydraulic oil lines and a central valve; when
cornering at speed, the system increases support of the spring-deflected
front wheel at the outside of the curve. The shock absorber
characteristic can be adjusted over three levels.
Equipment
The
Audi RS5 Cabriolet is delivered with an extensive set of standard
features. They include the parking system plus, driver and front
passenger seat heating, automatic belt feeder, wind deflector, lighting
package, driver information system with rest recommendation and a
comprehensive package of restraint systems. In case of an impending
roll-over accident, strong aluminum plates deploy upwards behind the
rear head restraints. Sporty and luxurious options include three-stage
head-level heating, convenience key, high-beam assistant, adaptive light
and three-zone deluxe automatic air conditioning.
All assistance systems offered in the A5
model lineup are available as options in the Audi RS5 Cabriolet as
well. Adaptive cruise control maintains the four-seat convertible at the
desired distance to a vehicle driving ahead in traffic and supports the
driver in braking. At speeds below 30 km/h (18.64 mph), it initiates a
full brake application in an emergency situation. Audi side assist
monitors the space behind the vehicle, which helps to ensure safe lane
changes. Audi active lane assist makes it easier to stay in a driving
lane. The parking system plus can be extended to include a reversing
camera.
In the multimedia field, Audi is offering a comprehensive
modular component system; at the very top there is MMI navigation plus
which includes a large hard drive, DVD drive and seven-inch color
monitor. An ideal complement is Audi connect with car phone, which
connects the Audi RS5 Cabriolet to the Internet. Audi connect lets
passengers freely surf the web with their mobile end devices via an
integrated WLAN hotspot. Customized online services from Audi connect
are also available to the driver - they range from Audi traffic
information online to navigation with Google Earth images and Street
View.
Customer deliveries of the Audi RS5 Cabriolet begin in early
2013 in Germany. The base price in the home market will be 88,500
euros.
