Press Release:

The fascination of open-top dynamism –
The Audi RS 5 Cabriolet 

Dynamic performance where the sky’s the limit: the Audi RS 5 Cabriolet. The four-seat convertible built by quattro GmbH in Neckarsulm offers a scintillating combination of elegance and dynamism. Its 4.2 FSI, a high-revving naturally aspirated V8 engine, with its 331 kW (450 hp) accelerates from zero to 100 km/h (62.14 mph) in 4.9 seconds. Sophisticated drivetrain and chassis solutions round out the package.

The high-revving V8 FSI develops 331 kW (450 hp) from its 4.2 liters of displacement, accelerating the Audi RS 5 Cabriolet from zero to 100 km/h (62.14 mph) in 4.9 seconds. The seven-speed S tronic and the quattro permanent all-wheel drive system reliably transmit power to the road. The chassis also boasts a wide array of high-tech solutions, ranging from carbon fiber brake discs to the sport suspension plus with Dynamic Ride Control (DRC). Sophisticated assistance and infotainment systems round out the offering.

The 4.2-liter FSI delivers 430 Nm (317.15 lb-ft) of torque to the crankshaft between 4,000 and 6,000 rpm. It produces 331 kW (450 hp) at 8,250 rpm. The long-stroke naturally aspirated engine develops 79.5 kW (108.1 hp) per liter displacement and special flaps in the exhaust tailpipe vary the sound. The convertible accelerates from a standstill to 100 km/h (62.14 mph) in 4.9 seconds – the best in its class. As an option, Audi can increase the top speed from 250 (155.34 mph) to 280 km/h (173.98 mph). The combined fuel consumption of the powerful V8 is 10.7 liters per 100 km (21.98 US mpg).

Thanks to the long ratio of its highest gear, the seven-speed S tronic makes a substantial contribution to efficiency. Drivers can employ the automatic dual-clutch transmission for instantaneous and smooth shifts in the D and S programs, or they can shift manually using the paddles on the steering wheel.

In its latest evolutionary stage, the quattro permanent all-wheel drive system features the self-locking crown-gear center differential and torque vectoring. Audi also offers the optional sport differential for the rear axle, which actively distributes power between the wheels.

Aluminum is used for much of the five-link front suspension and the self-tracking trapezoidal-link rear suspension on the Audi RS 5 Cabriolet. The speed-dependent power steering system is highly efficient with its electromechanical drive unit. The body is built 20 mm (0.79 in) lower to the groundthan on the Audi A5 Cabriolet, the axle mounts are stiffer, the anti-roll bars are larger and stronger. Aluminum forged wheels, size 9 J x 19 with 265/35 tires, come as standard, and Audi offers optional 20-inch wheels as well.

Internally ventilated, perforated discs in a weight-saving wave design (3 kg) (6.61 lb) lower in weight) bring the car to a stop; pins are used to join the discs to the aluminum brake pots – a concept adopted from motorsport. The front brake callipers operate with eight pistons each; Audi can deliver the car with fiber-reinforced ceramic discs as an option. The ESC stabilization system with Sport mode can be fully deactivated, if the driver prefers.

Audi drive select is a standard feature in the RS 5 Cabriolet. The driver can use this function to vary the characteristics of main technology components. These include the throttle valves, the seven-speed S tronic, the steering and the exhaust system sound flaps as well as the optional components: sport differential, dynamic steering, adaptive cruise control and the sport suspension plus with Dynamic Ride Control (DRC). The latter entails a hydromechanical system that operates without any delays; the shock absorber characteristic can be adjusted over three different maps.


Striking dynamism: exterior designThe dynamism of the Audi RS 5 Cabriolet instantly catches the eye thanks to its consummately balanced lines. Wedge-shaped headlights with wave-like lower edges illuminate with xenon plus lamps and LED strips for the daytime running lights. Large air intakes are embedded in the distinctively shaped front apron whose ends run out into splitter edges.

The frame of the hexagonal Singleframe grille is designed in matt aluminum look. Sill add-ons and wheel housing extensions dominate the car’s appearance in side profile.

The door mirror housings have a matt aluminum look, while anodized aluminum accentuates the windshield frame. The LED rear lights feature light strips. A spoiler lip in matt carbon increases downforce at the rear. The lip can also be painted in the exterior color as an option.

The lightweight textile soft top spans the interior of the 4.65 meter (15.26 ft) long Audi RS 5 Cabriolet like a low curved dome; a foam layer in the roof delivers high acoustic comfort. At the press of a button, the soft top can be opened or closed in 15 seconds or 17 seconds respectively – the top stows in just 60 liters (2.12 cubic ft) of the 380 liter (13.42 cubic ft) of luggage compartment when it is down. The split rear seatbacks can be individually folded to provide a large load-through space.

Entirely in black: the interiorThe interior of the four-seat convertible is finished entirely in sporty black; the inner soft top liner can be ordered in an optional star silver color. Carbon inlays are standard; optional alternatives include two different aluminum versions, a black piano finish and stainless steel mesh. Fine chrome accents and high-gloss black trim highlight the car’s exclusivity.

The leather-covered multifunction sports steering wheel in the RS 5 Cabriolet has a flat bottom; the black dials contrast with white numerals. The driver information system can display a menu with lap timer and an oil temperature gauge. The S sports seats with integrated head restraints feature power adjustment; they are upholstered in a combination of leather and Alcantara, with Fine Nappa leather also available as an option. The leather is pigmented to inhibit heating by sunlight.

All of the display elements and controls in the Audi RS 5 Cabriolet, including the monitor of the optional MMI navigation plus system, boast outstanding ergonomics. Exclusive optional equipment, advanced driver assistance systems and state-of-the-art infotainment modules round out the user control strategy. The lineup ranges from three-stage head-level heating and adaptive cruise control to Bluetooth car phone online, which integrates Audi connect services in the vehicle. In Germany, customer deliveries of the Audi RS 5 Cabriolet begin in early 2013. The base price in the domestic market will be 88,500 euros.

Drivetrain

The seven-speed S tronic makes an important contribution to the efficiency of the Audi RS 5 Cabriolet – its long seventh gear is designed to improve fuel economy, while its six lower gears feature sporty gear ratios. Engineers made specific modifications to the dual-clutch transmission compared to the standard production model, focusing on such areas as the transmission fluid supply and clutches.

The seven-speed S tronic consists of two subunits, and two multi-plate clutches control the gears. The large K1 clutch located on the outside transfers torque via a solid shaft to the gear wheels for gears 1, 3, 5 and 7.
A hollow shaft rotates around the solid shaft. It is connected to the smaller K2 clutch, which is integrated inside the K1 clutch, and which controls gear wheels for gears 2, 4 and 6, as well as reverse.

Both transmission subunits are continuously active, but only one is connected to the engine at any given time. For example, when the driver accelerates in third gear, the fourth gear is already engaged in the second transmission subunit. The shifting process involves switching the clutches – K1 opens and K2 closes. This takes just a few hundredths of a second with virtually no loss of tractive force; the process is dynamic, smooth and comfortable.

The seven-speed S tronic in the Audi RS 5 Cabriolet can be used in a variety of modes. Fully automatic modes include D (Drive) and S (Sport). The mode selected in Audi drive select is also integrated in the management. If the driver shifts manually using the selector lever or the paddles behind the steering wheel, the operating mode is extremely sporty – when accelerating, the S tronic no longer upshifts by itself. In dynamic mode in Audi drive select the downshift is accompanied with a dose of double-declutching.

State-of-the-art technology: the quattro drivetrainThe Audi RS 5 Cabriolet features the very latest version of the quattro drivetrain – with the self-locking crown-gear center differential and torque vectoring. At its heart lie two crown gears which rotate inside the differential; they owe their name to the crown-like design of their teeth. The front crown gear drives the output shaft to the front differential, the rear crown gear drives the propshaft to the rear axle. The two crown gears intermesh with four rotatable pinion gears, which are arranged at right angles to each other.

Under normal driving conditions, the crown gears rotate at the same speed as the differential housing, i.e. the transmission output shaft. Because of their special geometry, they are designed to have unequal lever effects: Normally 60 percent of the engine torque goes to the rear differential and 40 percent to the front differential.
If the torques change because one axle loses grip, this leads to different speeds and axial forces inside the differential and the integrated sets of plates are pressed together. The resulting self-locking effect diverts the majority of the torque to the axle with the better traction; up to 85 percent can flow to the rear axle. If the rear axle has less traction, up to 70 percent of the torque is diverted to the front axle.

With this extremely broad torque distribution range, the crown-gear center differential surpasses its predecessors. Forces are redistributed virtually without any time lag and absolutely consistently; the entirely mechanical operating principle guarantees maximum efficiency and instantaneous response. Other advantages of the technology are its compactness and low weight of 4.8 kilograms (10.58 lb).

Intelligent software solution: torque vectoringThe crown-gear differential in the Audi RS 5 Cabriolet works together with an intelligent software solution in the brake management system – the torque vectoring system, which acts on all four wheels. If during fast cornering the control unit detects that the wheels on the inside of the curve, which are under a reduced load, are about to slip, it brakes these wheels slightly - all that it takes is minimal pad pressure on a brake disc.
Torque vectoring works smoothly and continuously. The RS 5 Cabriolet maintains neutral handling for a long time even at performance limits. If the ESC stabilization control still needs to intervene, it does so later and gently.

As a complement to the quattro drivetrain, the optional sport differential is available, which actively distributes torque between the rear wheels. When turning into or accelerating in a curve, the majority of the torque flows to the outside wheel and pushes the four-seat convertible into the curve, counteracting the tendency to oversteer or understeer early.

With the sport differential, a superposition gear is added to each side of the classic rear differential; it comprises two sun gears and an internal gear which turns ten percent faster than the drive shaft. A multi-plate clutch in an oil bath and operated by an electrohydraulic actuator makes the power connection between the shaft and the superposition gear.

When the clutch engages, it steplessly imposes the higher speed of the superposition stage on the outside wheel. The additional torque required is obtained from the inside wheel via the differential. In this process, nearly all of the torque can be directed to one wheel. The maximum difference between the wheels is 1,800 Nm (1,327.61 lb-ft).

The sport differential works just as efficiently in overrun as it does under load and when coasting; it is electronically controlled with response times of just a few hundredths of a second. The controller calculates the ideal distribution of the forces for each driving situation as a function of the steering angle, yaw angle, lateral acceleration, speed and other information.

Convertible top and body

The soft top with the large glass rear window covers the interior like a low curved dome. It is much lighter than a folding steel roof, which reduces overall weight. Available as standard with an acoustic hood, the soft top reduces wind noise to virtually the level of a coupĂ©. A foam layer, which is up to 15 mm (0.59 in) thick, is inserted between the soft top cover and the interior lining. A LED lamp illuminates the rear seating area.

If the driver presses the opening button on the centre tunnel console or on the optional convenience key, a high-pressure hydraulic pump and four servo cylinders are activated. The soft top opens in 15 seconds and closes in 17 seconds, and can be operated at speeds up to 50 km/h (31.07 mph). A central switch activates the four window controls simultaneously. The opened hood disappears under a solid lid, where it folds compactly. Its roof compartment, made out of a heavy-duty textile mat, takes up just 60 liters (2.12 cubic ft) of luggage compartment capacity – the remaining 320 liters (11.30 cubic ft) constitute a best-in-class figure.
As with any Audi, the body of the RS 5 Cabriolet offers outstanding strength, providing the basis for precise handling, superior crash safety, and peace of mind. Form-hardened steels are used in the passenger cell area – a change in temperature during forming gives the steels extremely high tensile strength coupled with lower weight.

Specially developed reinforcement components compensate for the absence of a metal roof. In the front section, diagonal struts run from the side sills to the subframe; similar components are mounted to the rear section. The side skirts feature ultra-high-strength walls. The tubes, which reinforce the A-pillars, are formed by hydroforming and are extremely rigid.

A solid aluminum frame, which houses the rollover protection, is located between the interior and luggage compartment. In the case of an imminent rollover, pre-tensioned springs instantly push up aluminum supports behind the rear head restraints.

In the event of a side impact, head/thorax side airbags are ready in the seats; airbags protect the driver and the front seat passenger in a frontal impact – the control unit detects the relevant seat positions in this case. Thus the unit can adaptively control the triggering of seat belts and airbags. In a rear-end collision, the integral head restraint system averts the danger of whiplash injuries.

The front fenders of the RS 5 Cabriolet are made of aluminum to reduce weight and to optimize the distribution of axle loads. Sophisticated fine-tuning measures, including a fully covered underbody, improve the airflow and, in turn, acoustics as well as fuel efficiency.

Interior

The interior entices with its high-quality workmanship. User controls are intuitively simple – one of Audi’s classic strengths. All the buttons, switches, and levers are exactly where the driver expects them to be.
Trimmed in perforated leather, the multifunction sports steering wheel comes with a strong, flat-bottomed rim. The shift paddles come with an aluminum-look finish. The driver information system displays on request a RS-specific menu including lap timer and an oil temperature gauge. Just like the MMI monitor, the system displays an RS welcome page as the vehicle is started. The speedometer and rev counter have black scales, white dials and red needles.

The standard S front sports seats come with high bolsters, a removable seat cushion, four-way lumbar support, integrated head restraints, heating, and power adjustment. RS 5 logos are embossed in the backrests. Seat covers come in a combination of black leather and Alcantara, black or moon silver fine Nappa leather with piped seams in rock grey are available as an option. All grades of leather are pigmented to inhibit heating by sunlight. As an alternative to sports seats, Audi can also fit bucket seats for luxurious climate-controlled comfort seats with ventilation function. The Audi exclusive range includes exquisite leather packages, including bucket seats covered in diamond-quilted fine Nappa leather.

The interior of the RS 5 Cabriolet is finished in black; as an option Audi can also supply the soft top headlining in star silver. Carbon inlays are standard in the interior, but alternative inlays are also available optionally at no extra charge in matt brushed aluminum or Aluminum Race with its three-dimensional effect, black piano finish or light stainless steel mesh. The Audi exclusive range includes a selection of wood veneers as well as many other individualization options.

The surrounds on the instrument cluster and the centre console dazzle with their piano finish look; the selector lever knob on the seven-speed S tronic features RS-specific styling. The door openers taper to double, narrow bars – another hallmark RS detail. The pedals, the footrest, the air vent frames, the MMI buttons and many other controls shine with their aluminum-look finish, aluminum inserts adorn the door sill trims. RS 5 logos add striking touches in the interior.

The backrests of the two-seater rear seat bench have sporty contours and are symmetrically split. They can be unlocked by actuating levers in the trunk and drop automatically onto the seat cushions thanks to pre-tensioned springs. The large standard pass-through provides a total loading length of 1.76 meters (5.77 ft) and 750 liters (26.49 cubic ft) of stowage space. Audi offers a ski/snowboard bag as an option.
