EXTERIOR















The Audi RS5 Cabriolet provides an accomplished combination of Audi's design idiom and the fascination of a four-seat convertible. The high-performance convertible is 4,649 mm (183.03 in) long and 1,860 mm (73.23 in) wide, but just 1,380 mm (54.33 in) in height. The long hood, a wheelbase of 2,751 mm (108.31 in) and clean lines create a flowing silhouette with finely balanced proportions and striking details...

The tapered Singleframe grille dominates the front end, its side edges extending beyond the hood. A frame in a matt aluminum look encloses the grille, the honeycomb grille insert that sports an RS5 logo shines in anthracite. The wedge-shaped headlights with wave-like lower edges draw the eye to the vehicle's exterior, creating the visual sensation of more width. The xenon plus lamps inside the headlights surround the LED strips that form the daytime running lights...

The large side air intakes combine with the flat central intake under the grille to accentuate the width of the front end. The two exterior intakes sport honeycomb grilles and are divided up by vertical and horizontal struts into six segments in each direction. They are integrated into a boldly contoured bumper that tapers into a powerful aluminum-look splitter edge...

An anodized aluminum strip on the windshield frame, a classic feature of all Audi convertibles, lends the vehicle a stylish touch. The decorative trim strips on the window channels and the soft top box cover are made of the same material, and the door mirror housings are finished in a matt aluminum look. Crisp, taut surfaces and sharp contour edges characterize the side lines - the dynamic line runs over the side sills, the sweeping tornado line below the windows. The wide shoulders, the powerfully flared wheel arches, the large wheels and the angular sill trims are testimony to the raw power of the Audi RS5 Cabriolet..

The lines also emphasize the impression of sporty width at the rear. The luggage compartment cover sports an RS5 logo and a subtle spoiler lip made out of matt carbon; the lip can also be painted in the body color as an option. The two large, elliptical tailpipe tips of the dual exhaust system enclose the diffuser, which extends far upward...

A contour painted in the body color (available optionally in aluminum look) splits the diffusor into two sections, with the upper section featuring a honeycomb insert...

The Audi RS5 Cabriolet is available in eight exterior paint finishes - the Ibis White non-metallic finish, the metallic Suzuka Grey, the pearl effect variants Daytona Grey, Misano Red and Phantom Black along with the specially pigmented crystal effect finishes Panther Black, Estoril Blue and Prism Silver. In addition, a virtually unlimited range of customized paint finishes is available exclusively from Audi. 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 with carbon trim...

STRIKING DYNAMISM : The dynamism of the Audi RS5 Cabriolet instantly catches the eye thanks to its consummately balanced lines.

The lightweight textile soft top spans the interior of the 4.65 meter (15.26 ft) long Audi RS5 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...



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. RS5 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 Audi RS5 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. RS5 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...

ENTIRELY IN BLACK :  The 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...

ROOF






The numbers are remarkable. Just as you'd expect from a vehicle as sporty as the Audi RS 5 Cabriolet. It takes a mere 17 seconds to deploy the vehicle's retractable roof. An achievement that's possible at a cruising speed of up to 31 mph. And if that weren't impressive enough, the strong yet lightweight soft-top folds neatly away to preserve trunk space. Of course it does, it's an Audi.


PERFORMANCE


The RS5 Cabriolet is certainly fast. With a V8 that redlines at 8,500 rpm, the car just goes. Although I haven’t yet had a chance to take it on the track (Road America this summer, hopefully), it is great fun to drive in town and on winding country roads. The smooth-shifting dual clutch transmission is absolutely astounding, with extremely fast shifting. Put the car into manual shift mode or shift it with the paddles and you’re sure to be impressed with just how fast it shifts either up or down; as if it’s anticipating your next request. True believers may be disappointed to hear there’s no manual transmission option available, but all but the most die-hard will realize the benefits of a superb automatic transmission when they get behind the wheel of the RS5...

The Cabriolet version of the RS5, while not quite as fast as the hardtop, has a very quick 0-to-60 time that is estimated to be just under 5.0 seconds and a top speed electronically limited to 174 mph. Cornering is excellent with very little body roll and the all-wheel drive system along with fat summer tires keep it stuck to the road. The big V8 means the car is heavy up front and you can feel it hanging up there during turns. Audi compensates somewhat for the big engine up front with an active rear differential that can send power to the rear wheels individually and stability control which can brake the inside wheels during a turn...



CONVERTIBLE 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 coupe. 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 RS5 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 RS5 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...



TECHNOLOGY




The RS5, as tested, has Audi’s MMI Navigation plus package ($4,000), which includes the GPS Navigation displayed on a 6.5” color screen, HD Radio, rear view camera, side assist, an in-dash DVD player (not available while the vehicle is in motion), and SiriusXM Satellite Radio with 90-day trial subscription... 

With Audi Connect, the vehicle links to a cellular data plan, which provides a data connection for the car and also allows the vehicle to become a Wi-Fi hotspot. (Again, a trial subscription is included, this one six months in duration.) Through the data services, the navigation system retrieves traffic data, integrates with Google’s search engine, and also provides the use of Google Earth mapping instead of Audi’s standard maps if the driver chooses...

When switching between map modes, the car retrieves Google Earth information from the Internet and can take several seconds to update. The Google Earth implementation even allows the user to zoom in to use Google’s Street View to preview destinations, for example. While the Google Earth view is useful and it’s sometimes very informative to see aerial views of the surrounding buildings and roads, I preferred Audi’s standard maps in 3D perspective, which provides a clearer view of the roads as well as points of interest...

 While driving, the dash between the speedometer and the tachometer can be changed to display the next turn in the navigation. That display can also be used to show stats like average mileage, distance to empty, and radio information...

The Audi MMI system also provides for integration with smartphones which can be connected via Bluetooth or directly through a cable in the glovebox (standard is an Apple 30-pin connector and an adapter is required for use with the latest 5th generation iPhones or other smartphones). I have mine set up to play music from my iPhone via the Bluetooth connection and can play Pandora radio or stream other audio from the smartphone through the Bluetooth connection and see track information and skip forward and backward using the dashboard controls...

 Audi, for some reason, also includes two SD card slots hidden in the dash which can be used as media sources. It might be a useful way to transfer audio books, podcasts, or other media you wish to change frequently, but I’d just use my iPhone for any of those things anyway...

The MMI interface is also used for climate control. Each seat has individual settings for the desired temperature. A separate dial on the dashboard controls each side’s air temperature and heated seat, with the MMI interface being used to show the current selection when either is being adjusted...

The RS5 also comes with a keyless entry system. You can keep the key fob in your pocket while operating the vehicle. When you approach within a couple feet of the car, it will unlock automatically. Starting the car requires one foot on the brake and push of the Start button. You can also insert the key fob in the dash and push it inward to start, if you prefer that for some reason. When exiting the car, there is a small button on the exterior of each door handle that, when pushed locks the car and engages the security system...



EQUIPMENTS & TRIM











The Audi RS5 Cabriolet will go on sale to customers in Germany in early 2013, with a base price of 88,500 euros. The standard equipment is wide-ranging - apart from the features already mentioned, the lineup includes parking system plus, automatic belt feeders, an electromechanical parking brake, automatic climate control, wind deflector, concert radio with CD player and eight loudspeakers, a lighting package, and a restraint system package that includes six airbags, integral Audi head restraint system, and ISOFIX anchor points for child safety seats in the rear...

Customers looking for even more comfort will find what they are looking for in the Options items. The range includes the convenience key, the high-beam assist, adaptive light, head-level heating, rear seat heating, memory function for the driver's seat and deluxe automatic air conditioning with three-zone control...

All of the assistance systems from the A5 series are available in the new Audi RS5 Cabriolet. The driver information system with rest recommendation function is standard; it detects when the driver is getting tired...

Adaptive cruise control maintains the four-seat convertible at the required speed and at a constant distance to the vehicle ahead; at speeds below 30 km/h (18.64 mph) it can trigger emergency braking should the need arise. Audi side assist makes changing lanes safer, Audi active lane assist uses slight steering interventions in the electromechanical power steering to help the driver to stay in the driving lane, and the parking system plus with reversing camera facilitates maneuvering...

The system lineup is just as extensive when it comes to infotainment. The top-of-the-line version is the MMI navigation plus - a high-end media control center with large hard drive, DVD player and seven-inch color monitor with 3-D graphics...

The Bang & Olufsen Sound System controls 12 loudspeakers with an output of 505 watts...

The Bluetooth car phone online provides the perfect complement to MMI navigation plus - it connects the Audi RS5 Cabriolet to the Internet via a UMTS module. Passengers can use their mobile devices to seamlessly access the web via the integrated WLAN hotspot. For the driver, the system delivers customized online services from Audi connect to the car - they range from Audi online traffic information to navigation with images from Google Earth and Google Maps Street View and Audi music stream web radio...



WHEELS



The new Audi RS5 Cabriolet is equipped with ten-spoke machine-polished aluminum forged wheels, size 9J x 19 with 265/35 tires. 20-inch wheels with 275/30 tires in three designs are available as options. 19-inch tires, size 8J x 19 with 235/40 R19 tires, are offered for winter use. All of the tires exhibit low rolling resistance without any compromises in handling or braking performance...


BRAKE




Large wave-design brake discs are mounted on the wheels. Discs measuring 365 mm (14.37 in) in diameter and 34 mm (1.34 in) thick are mounted on the front axle; the rear axle features discs measuring 324 x 22 mm (12.76 x 0.87 in). The discs are internally ventilated and perforated; their wave-shaped outer contour reduces weight by about three kilograms (6.61 lb). Stainless steel pins connect the steel friction rings to the aluminum brake pots. This concept, which has its origins in car racing, reduces loads and quickly dissipates heat...

The monoblock callipers painted in high-sheen black with RS logo are also manufactured from aluminum. The front callipers each have eight pistons; single-piston floating callipers are mounted on the rear axle...

For the front axle, Audi offers the option of 380 mm (14.96 in) perforated carbon fiber ceramic discs paired with six-piston callipers in Anthracite Gray. The base material is silicon carbide, a material with a diamond-like crystalline structure that integrates high-strength carbon fibers. Titanium bolts join the friction rings with the pots made out of forged aluminum. The ceramic discs do not fade, and they are extremely strong, powerful, and durable. All in all, they weigh four kilograms (8.82 lb) less than the steel discs, despite their larger dimensions...

The ESC stabilization control is tuned to the dynamic character of the Audi RS5 Cabriolet. In Sport mode, which can be selected at the push of a button, the engine interventions are deactivated, providing spectacular yet safe drifts when accelerating. The optional hill start assist, a subfunction of the system, makes it easier to drive off on grades by maintaining brake system pressure after the brake pedal is released...



SETUP & DYNAMIC SYSTEMS


The RS5 Cabriolet will launch with dynamic tuning; the body has been lowered by 20 mm (0.79 in). The shock absorbers are stiff, taut springs ensure sporty elasto-kinematics, and the tubular anti-roll bars are larger and stronger than on standard production models...

Audi offers the sport suspension plus with Dynamic Ride Control (DRC) as an option - the compact, lightweight system minimizes body movements by pure hydromechanical means without delays. Each pair of shock absorbers is interconnected diagonally via hydraulic lines and to one central valve each...

When cornering at speed, the valves send more oil flow to the shock absorber of the deflected outside front wheel to increase its support and reduce lateral tilt. The shock absorbers can be adjusted in three stages via the standard Audi drive select...

Audi drive select takes dynamic handling to new heights on the RS5 Cabriolet. In addition to the sport suspension plus and the sport differential, both of which are optional, Audi drive select also incorporates the power steering system, seven-speed S tronic, engine throttle valves and the sound flaps of the exhaust system. The driver can vary the functionality of these systems at the push of a button between the modes comfort, auto and dynamic. And if the car is equipped with an MMI navigation system, there is also a customizable fourth mode which offers the driver a wide range of configuration options...

Another optional component is dynamic steering which uses a superposition gear in the steering column. It steplessly varies the steering ratio as a function of speed - from very direct when maneuvering to indirect on the highway. At cornering performance limits, dynamic steering countersteers with minimal pulses, making handling even more dynamic, fluid and safe. It prevents the car from pulling when braking on a surface that is slippery on one side...



SAFETY


Standard safety features on the 2014 Audi RS 5 include antilock disc brakes, stability and traction control, front seat side airbags, front knee airbags, full-length side curtain airbags (coupe only) and front and rear parking sensors. Optional items include a rearview camera, a blind-spot monitoring system and an automatic emergency braking system that is paired with the adaptive cruise control...

In Edmunds brake testing, the RS 5 coupe came to a stop from 60 mph in 105 feet while the Cabriolet took just a foot longer. These impressively short distances are actually about average for this high-performance segment...



DRIVETRAIN


The seven-speed S tronic makes an important contribution to the efficiency of the Audi RS5 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 RS5 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...



CHASSIS


All the important wheel suspension components consist of aluminum, which substantially reduces unsprung masses. The five-link front suspension processes the longitudinal and lateral forces that act on the vehicle separately. The aluminum frame to which it is linked makes the front end extremely rigid. The springs and dampers of the self-tracking trapezoidal link rear suspension are independent, which improves their response. The links are mounted on a steel subframe...

The electromechanical power steering conveys differentiated feedback to the driver. Power assistance is adapted to the road speed; the ratio of 16.3:1 is sporty and direct. The steering system works closely together with the optional Audi active lane assist system. When braking on a surface that is slippery on one side, it assists the driver by increasing power assist to support the proper steering corrections and prevent incorrect steering inputs...

In straight-line driving, the electric motor of the steering system in the Audi RS5 Cabriolet does not consume any energy, reducing fuel consumption by up to 0.3 liters (0.08 US gallons) per 100 km (62.14 miles). Thanks to its concentric design with the rack and pinion, the steering gear is very compact...



ENGINE






The 4.2 FSI in the Audi RS5 Cabriolet combines high torque with spontaneous response and dynamic high-revving flexibility. The naturally aspirated V8 produces 430 Nm (317.15 lb-ft) of torque from 4,000 to 6,000 rpm. At 8,250 rpm, it develops 331 kW (450 hp) from 4,163 cc of displacement; the high-revving fun is not electronically limited until 8,500 rpm. The specific power output is 79.5 kW (108.1 hp) per liter engine displacement; each hp only needs to move 4.27 kg (9.41 lb) of vehicle weight...

The 4.2 FSI accelerates the Audi RS5 Cabriolet from 0 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). Despite its high performance, the powerful V8 delivers astonishingly high efficiency: in the NEDC cycle, the eight-cylinder unit has a combined fuel consumption value of 10.7 liters per 100 km (21.98 US mpg). The cylinder liners and the chain drive have been optimized for minimal friction, and the oil pump features need-based control...

Audi manually assembles the 4.2 FSI at its Hungarian engine plant in Györ. The engine features a classic cylinder angle of 90°; the two banks are offset by 18.5 mm (0.73 in). With a stroke/bore ratio of 92.8 mm (3.65 in) to 84.5 mm (3.33 in), the V8 has a long-stroke design. Its valve covers are painted red...

The high-performance V8 tips the scales at just 216 kg (476.20 lb). The forged-steel connecting rods, the pistons forged from a high-strength aluminum alloy and the forged crankshaft are lightweight yet extremely strong. The crankcase is produced in a low-pressure die-casting process that ensures very good material uniformity. Its aluminum-silicon alloy combines low weight with high strength. Its high silicon content makes the cylinder liners extremely wear-resistant...

In the crankcase, with its bedplate design, a frame supports the bearing blocks for the crankshaft, ensuring maximum strength and optimal vibration characteristics. The cast iron bearing blocks control thermal expansion of the crankcase, which maintains play at the main bearings of the crankshaft within tight limits...

Like all Audi gasoline engines, the fuel is distributed to the 4.2 FSI by means of common-rail direct injection. The fuel swirls intensely in the combustion chambers, which cools the chamber walls. This process minimizes the risk of autoignition of the mixture on hot spots. This results in an exceptionally high compression ratio of 12.5 : 1, which has a beneficial effect on both performance and efficiency....

The four camshafts, which can be hydraulically adjusted through 42 degrees of crankshaft angle, are actuated by chain drives running on the back side of the engine. Roller-type cam followers actuate 32 large-diameter valves - 33.9 mm (1.33 in) on the intake side, 28.0 mm (1.10 in) with the sodium-cooled exhaust valves. The intake manifold is made of plastic...

The 4.2 FSI naturally inducts intake air and exhausts gases freely thanks to sophisticated fine-tuning on the twin-pipe intake and exhaust system with the two throttle valves. Vacuum-actuated tumble flaps are integrated into the intake ports. Controlled by the engine management system, they cause the intake air to flow with a cylindrical swirling motion at part load, which improves combustion speed and, in turn, efficiency...

The exhaust system pipes are produced from stainless steel using hydroforming; flaps are installed in the two large tailpipes. If they open at high load and revs - or at the push of a button in the Audi drive select system -, making the sound of the V8 even fuller. As an option, Audi can deliver the car with a sport exhaust system with black tailpipe trim, also with flap switching function...
