Audi R8

2007-12-03

Panel of experts decides:
The Audi R8 is "SportsCar 2007"

Only pure-bred sports cars are crowned “SportsCar” of the year by a panel of experts in the Autobild SportsCars monthly magazine. Following its victory in the March 2007 issue, the Audi R8 has now been awarded top place overall, and has thus secured the title of “SportsCar 2007”, one of the German car industry’s most sought-after awards.


The trophy was presented to Werner Frowein, Managing Director of quattro GmbH, during the magazine’s “Race Night”, which formed part of the Essen Motor Show. The Audi subsidiary was responsible for developing the 420 bhp mid-engined R8 sports car, which it also manufactures. The R8 is hand-built at quattro GmbH in Neckarsulm.

Together with the TÜV Rheinland inspection authority, members of the magazine’s panel conduct demanding on-road tests on an ongoing basis to assess the qualities of the very latest sports cars. They then present their favourites as the monthly winners in each new issue. At the end of October, the jury cast a discerning eye on the twelve winning vehicles at the Contidrom test circuit in Hanover.

The experts’ concluding remarks: “The Audi R8 wins because it is currently the most complete vehicle with the hottest body in the sports segment and, despite being a newcomer, displays no serious weaknesses.”

Lamborghini Reventon

Sant’Agata Bolognese/Frankfurt, September 11th 2007
Press Release
Automobili Lamborghini presents the new Lamborghini Reventón at the Frankfurt Motorshow 2007
The most extreme
The essence of the marque: just 20 examples of a design masterpiece
Clearly a Lamborghini, but nothing quite like it. A super car without equals: the Lamborghini Reventón is a road vehicle with an extreme specification and, at the same time, a limited edition masterpiece – a coherent style, angular with sharp lines, inspired by the very latest aeronautics.
With just 20 produced, each 1 Million Euro (without taxes) Lamborghini Reventón is a symbol of extreme exclusivity, yet still offering the extraordinary performance that makes the Reventón so unrivalled: under the completely autonomous design, the Reventón possesses the entire technical and dynamic competence of the twelve cylinder Lamborghini.
Lamborghini prides itself on being the extraordinary manufacturer of extreme super sports cars without compromise. Sensuality and provocation characterise every Lamborghini, with an aggressively innovative style. “However, the Reventón is the most extreme of all, a true automotive superlative. Our designers at the Lamborghini Style Centre took the technical base of the Murciélago LP640 and compressed and intensified its DNA, its genetic code,” affirms Stephan Winkelmann, President and CEO of Automobili Lamborghini S.p.A.

Born in Sant’Agata Bolognese
The Lamborghini Reventón has been entirely designed in Sant’Agata Bolognese, the original birthplace of the Lamborghini and the native home of every super car born under the sign of the bull. The design drawn up in Lamborghini’s Centro Stile (Style Centre) is fine-tuned in close collaboration with the Lamborghini Research and Development Department. Thus, the Reventón is not only “haute couture” but it also stands out for its elevated dynamism whilst being entirely suitable for every day use.
The Lamborghini Reventón is not destined to remain a one-off. A total of 20 Lamborghini friends and collectors will be able to own this extraordinary car and, naturally, enjoy the incomparable pleasure of driving it.
The name Reventón has been chosen according to Lamborghini tradition. Reventón was a fighting bull, owned by the Don Rodriguez family. It is included in the list of the most famous bulls ever and is known for killing the famed bullfighter Felix Guzman in 1943.
Inspired by the fastest airplanes
The present day Lamborghini models are distinguished by the clear language of their shape. The coherent proportions of the Murciélago and Gallardo highlight their power and dynamism. Sharp edges, precise lines and clean surfaces: these are ingredients of a style reduced to the essential. Each element is created exactly according to its function; ornaments and decorations are totally foreign to a Lamborghini.
With the Reventón the Centro Stile designers have coherently developed this philosophy, inspired by another sphere where speed and dynamism reign absolute: modern aeronautics, responsible for the fastest and most agile airplanes in the world. This has created an extremely precise, technically striking style with a new vitality: interrupted lines and contorted surfaces create a fascinating play of light, giving the car incredible movement.
Made of carbon fibre and precision
Although it is based on the extraordinarily successful Murciélago LP640, the exterior design of the Reventón is completely new. Just like the base model, the exterior is made of CFC, a composite carbon fibre material, which is as stable as it is light. The exterior components are glued and fixed to the body comprised of CFC and steel.
The front is characterised by the acute angle of the central ‘arrow’ and by the powerful forward-facing air intakes. Although they do not supply air directly to the turbine like an airplane, bearing in mind the 650 hp, an abundant volume of air is necessary to cool the carbon brake disks and the six cylinder callipers.
Characterised by coherent functions
Naturally, both doors on the Reventón open upwards – since the legendary Countach this has also been a symbol of the V12 Lamborghini product line. With their asymmetric configuration, the large air intakes below the doors provide an example of the extreme coherence with which a Lamborghini fulfils its function: on the driver's side it is large to increase the flow of oil to the radiator. On the passenger’s side of the vehicle, the air intake is flat because in this case, it only has to ensure the flow below the floor. The aerodynamically optimised flat floor structure terminates at the rear with a diffuser featuring an accentuated shape. This guarantees excellent road grip and stability even at 340 km per hour.
In spite of the extreme and innovative language of its shape, the Reventón not only maintains all the strong features of the Murciélago LP640, but also offers further amelioration in terms of aerodynamics, the important engine cooling system, the air intake system and brakes. The airflow and the section of the variable geometry air intakes of the engine and the rear spoiler (also adjustable) have been modified.
Owners of the 20 examples will be able to test the performance of his or her Lamborghini in person.
Perfected to the ultimate detail
The engine hood made of glass laminate with open ventilation slits offers a glimpse of the beating heart of the twelve cylinders of the super car. The glass also features the
marked arrow angle that characterises the design from the front to the rear spoiler. The Lamborghini designers’ love for detail is beautifully illustrated by the fuel tank lid: a small mechanical work of art, achieved by milling a solid aluminium block.
The combination lights transform the incisiveness of the design into light: the front features the most modern light-emitting diodes alongside Bi-Xenon headlights. Seven LEDs ensure continuous daylight while there are a further nine diodes for the indicator and hazard lights. Another technical innovation is found in the rear light LEDs. Because of the high temperature in the rear low part of the car, special heatproof LEDs are used for the indicator and hazard lights, stoplights and rear lights with a triple arrow optical effect.
A new body colour
Naturally, such a refined language of shape also demands an extraordinary colour. For the 20 examples of the Reventón, the designers from Sant’Agata Bolognese have created a totally new hue: Reventón, a mid opaque green/grey without the usual shine. However, thanks to the metallic particles, in the daylight this colour tone features surprising depth.
Opaque and brilliant colours for the wheel rims
This play of opaque and lustre is also featured on the wheel rims, especially created for the Reventón. Opaque carbon fins are screwed onto the black aluminium spokes, not only creating a visual effect with the precision of a surgeon’s scalpel, but a turbine effect also ensures optimum cooling for the powerful ceramic brake disks.
TFT display similar to an airplane
The same innovative force applied to the exterior design characterises the cockpit of the Reventón. Designed and created using Alcantara, carbon, aluminium and leather that comply with the top quality standards, the interior is inspired by the next generation cockpits: just like in modern airplanes, the instruments comprise three TFT liquid crystal displays with innovative display modes. At the touch of a button, the driver can choose from two vehicle information display modes. The instruments are housed in a structure milled from a solid aluminium block, protected by a carbon fibre casing.
The G-Force-Meter is also completely new: this display shows the dynamic drive forces, longitudinal acceleration during acceleration and braking, as well as transversal acceleration around bends. These forces are represented by the movement of an indicator on a graduated 3D grid depending on the direction and intensity of the acceleration. A similar instrument can be found in the airplanes. Formula One teams also use a similar device to analyse dynamic forces.
Customisable instruments
The instrument on the left of the speedometer associates the number of revolutions in the form of a luminous column with the display of the selected gear. Finally, every Reventón is equipped with a robotised e.gear controlled by two small levers under the steering wheel.
By simply pressing a button, the driver can switch to the second, quasi-analogical display, where the classic circular instruments, speedometer and engine speed indicator are configured in an equally innovative way and transformed into luminous pilot lamps with varying colours. The G-Force-Meter naturally remains at the centre in this display mode.
Electronic system developed entirely by Lamborghini
All this is possible thanks to the fact that the entire electronic platform of the Reventón, together with all the control devices, has been autonomously developed by the Lamborghini experts.
The same process for integrating the electronic displays in the car was applied to the Lamborghini Engineering Department.
From the conception of the very first radical ideas, the entire Reventón has been developed in Sant’Agata Bolognese thanks to tight teams of remarkably creative experts. An extremely refined and efficient process was employed: CAD design and development, creation of the prototype in the Prototype Department, all carried out under the constant supervision of the Research and Development Department’s technicians and testers.
Atelier of creativity and high efficiency
Inaugurated in 2004, the Centro Stile is dedicated to design and characterised by a high degree of efficiency: an “atelier” of creators, designers and prototype constructors, who encapsulate the Lamborghini culture and spirit by using their remarkable skills to create aesthetic innovation.
The Centro Stile is located in a 2,900 square two-storey building. The large pavilion houses two test floors and related production and analysis equipment, while other rooms are set aside for the most advanced computerised workstations for designers and a style-model construction workshop. The Centro Stile is also closely linked to the nearby Engineering Department: the direct line between the Lamborghini development departments guarantees that ideas rapidly become reality.
Creativity and production under the same roof
The Lamborghini Reventón is a practical illustration of the streamlined functionality and efficiency characterising the Centro Stile: it took less than a year to progress from the first ideas to the finished car. The complete design process from the first sketches on paper, to three dimensional computer models with 1:10 or 1:4 scale, right up to the real size prototype is organised around streamlined, fast, efficient work groups. Thanks to the Centro Stile, for the first time in its history, Lamborghini is now able to create its own style philosophy in-house without having to rely on any external collaboration.
The 20 units will be manufactured in Sant’Agata, using a production process characterised by artisan perfection and rigorous quality standards.
A masterpiece with tested technology
The technology found in the Murciélago LP640 has not been modified. The engine in the LP640 forwards is the classic twelve-cylinder engine with 6.5 litre displacement. Only for this car, Lamborghini guarantees, an astounding 650 HP (478 kW) at 8,000 revolutions per minute (rpm). The huge torque, equal to maximum 660 Nm, ensures a powerful switch from any number of revolutions: even the slightest pressure on the accelerator is spontaneously transformed into thrust. The robotised e.gear changes gear faster than even the most expert driver. In addition, the permanent Viscous Traction four-wheel drive system ensures that every force is constantly translated into movement.
As in the original Murciélago LP640, the Reventón accelerates from 0 to 100 km/h in just 3.4 seconds, with a maximum speed over 340 km/h.
Born to become a legend
Since its foundation, Lamborghini has been a creator of trends in the world of sports cars and has always manufactured cars with an absolutely unmistakable character. Models such as the Miura or Countach, for example, were veritable forerunners and rapidly acquired the status of timeless classic cars. From the moment they are launched, every new Lamborghini promises to become a legend, destined to become a sought-after and precious possession.
With the Lamborghini Reventón, Lamborghini has done it again; it has created an unequalled super car; the perfect synthesis between the exclusivity and appeal of a limited edition design masterpiece, and the dynamism and driveability of a standard sports car. Thus, the Lamborghini legend is further enhanced by another, stylish future classic.

The Audi A3 Cabriolet

Open for sport
The Audi A3 Cabriolet

Sporty, elegant, emotion-packed – the new Audi A3 Cabriolet is making its appearance in perfect time for spring 2008. The open-top Audi A3 is the premium option in the compact class. It offers the sporting genes of the A3 coupled with the uncompromising quality that distinguishes every Audi model. There are four engines to choose from, together with an extensive range of individual equipment options. Sales commence in Germany at the start of February 2008.

Audi convertible models generally sport a classic fabric top – and in the case of the Audi A3 Cabriolet this feature lends its profile a note of harmonious elegance and coupé-like sportiness. Its soft top is notable for its light weight and excellent fit. It can be opened hydraulically in just nine seconds; when open, it takes up very little space. The hood is available in semi-automatic and fully automatic versions, in the latter instance as a specially soundproofed acoustic hood.

The body structure of this premium convertible from Audi contains a high proportion of high-strength, ultra-high-strength and hot-formed steels, as well as a large number of reinforcing measures that provide maximum rigidity and crash safety. Inside, the accustomed uncompromising build quality, attractive design and exemplary ergonomics create an atmosphere of sporting elegance. There is ample space here for four occupants. The rear seat backs can be folded down, increasing the luggage capacity from 260 to 674 litres – whether the hood is up or down!

The A3 Cabriolet is being built in four engine versions – two petrol and two TDI. They combine ample power with impressive efficiency. All of them are direct injection units with turbocharging. The performance range extends from 77 kW (105 bhp) to 147 kW (200 bhp). As an option, the innovative S tronic dual-clutch gearbox takes charge of applying the engine's power to the wheels.

The Audi dynamic suspension lends the A3 Cabriolet superior agility. It comes complete with responsive electromechanical power steering, which consumes very little energy. The four-link rear suspension combines superb comfort with sporty handling properties. As well as the standard suspension, there is also the option of sports suspension.

Audi is offering the Audi A3 Cabriolet in the Attraction and Ambition equipment lines. In both cases its equipment specification is extensive and the Ambition line includes 17-inch aluminium wheels, sports suspension and sports seats, among other features. An S line exterior package and S line sports package are available from quattro GmbH.

The exterior design

There are many arguments in favour of the classic soft top as featured on Audi convertible models. One of them is evident at first sight: the harmonious proportions. Thanks to the hood's compact folding design, Audi's designers were able to create a four-seater with appealing lines. With the roof open, the Audi A3 Cabriolet looks compact and light; with the roof closed, it radiates the elegance of a coupé. Measuring 4,238 millimetres in length, 1,765 mm in width and 1,424 mm in height, it ranks among the sporty compact models in its competitive field.

The strong presence of the A3 Cabriolet is typical of the Audi brand. The interplay between its surfaces lends the body the character of a sculpture; these lines are framed by the forward urge of its lines. The horizontal dynamic line above the sill and the ascending shoulder line create the impression of a more elongated body.

The face of the A3 Cabriolet is dominated by the large single-frame grille, but the headlights are also an eye-catching feature. The precision of their design gives visible expression to the perfectionism of the brand with the four rings. They can be supplied optionally with xenon plus lights, which can operate in tandem with the dynamic adaptive light technology. The "wing" – a chrome vapour-coated wing-shaped contour – has become established as a characteristic Audi element; its form varies depending on the type of headlight.

The daytime running lights in the form of an integral light strip – an important safety feature at Audi – comprise seven white light-emitting diodes in conjunction with the xenon plus units. Similarly to the headlights, the rear lights of the A3 Cabriolet are of a flat, broad design. Their technology is based on fibre optic rods, but the visual effect is of two radiant rings that clearly distinguish the car as an Audi even after dark.

When viewed side-on, the athletic physique of the Audi A3 Cabriolet is clearly in evidence. The striking wheel arches accommodate large wheels: in the case of the Attraction equipment line, 16 inches in diameter. The Ambition version has 17-inch wheels made from cast aluminium. 18-inch wheels from quattro GmbH are available as an option. Audi supplies the A3 Cabriolet in 15 paint colours that can be combined with three hood colours – black, blue and red.

The hood and body

Audi has remained faithful to its successful line: the new A3 Cabriolet likewise has a classic fabric top. This blends in perfectly with the original, authentic idea of open-top driving and the feeling of carefree agility. The hood keeps its shape thanks to the mechanically moved metal linkage, which assures an excellent close fit, perfect tightness and the silhouette of a coupé. A large, heated glass rear window affords a good view to the rear.

Audi can supply the fabric top in two versions – the semi-automatic soft top and the fully automatic acoustic hood. In both cases the hood is moved by a high-pressure pump with two hydraulic cylinders. They open the large soft top in an extremely rapid nine seconds. This means that even a short stop at traffic lights is long enough to complete the process.

When lowered, the hood is folded up in a Z-pattern so that it takes up a minimum amount of space. The header – a board at its front edge – comes to rest on top, basically flush with the body, with the result that the structure needs neither a tonneau cover nor a cover flap. The folded hood is set down in a compact sheet steel compartment that reduces the luggage compartment capacity only very slightly. The high-performance kinematics mean that the acoustic hood can also be opened and closed at speeds of up to 30 km/h – a big advantage in terms of convenience when driving in urban traffic. The process is controlled by a switch on the centre console; the hood can also be opened and closed conveniently from outside the car, via the ignition key in the door lock.

The fully automatic soft top takes the form of an acoustic hood. Between the outer skin and the inner lining there is a synthetic fibre mat that further improves thermal insulation and soundproofing – at a speed of 140 km/h it is only 1 dB (A) louder inside the Audi A3 Cabriolet than in the A3. If only the front seats are occupied, a wind deflector can be erected above the rear bench seat in a few simple steps from one side of the vehicle.

High-strength steel: low weight and maximum rigidity

An extensive package of measures gives the body of the A3 Cabriolet its rigidity, and this open-top Audi drives with the same standards of precision, agility and comfort as the A3 with permanent roof. 45 percent of the bodyshell is made from high-strength steels, while nine percent in fact consists of ultra-high-strength steels, combining low weight with maximum rigidity. The roof frame and roll-over bar incorporate hot-formed steels for maximum safety.

Reinforcing profiles are integrated into the side sills and vehicle floor. V-pattern steel profiles additionally reinforce the forward structure and rear end, and there is a capsule with another reinforcing frame beneath the engine compartment. There are high-strength panels in the B-posts.

A box-shaped structure made from high-strength sheet steel separates the passenger compartment from the luggage compartment. The roll-over bars of hot-formed steel tubing are bolted into this structure. Similar high-tech tubes serve to reinforce the A-posts internally. Head/thorax side airbags are integrated into the backs of the front seats. In the event of a rear-end collision, the Audi integrated head restraint system promptly cushions the head and upper body.

The interior

The interior of the Audi A3 Cabriolet radiates an air of sporting elegance; its materials, Audi's accustomed uncompromising build quality and its design accentuate the premium character of this new convertible model. Calm lines border its large surfaces. The four round air vents and the side knee cushions on the centre console's struts are reminiscent of the Audi TT.

It is a matter of honour for Audi to maintain the perfect standards of ergonomics that it has pioneered. The speedometer and rev counter's red needles sweep across dials in a sporty black. On the Ambition equipment line, the A3 Cabriolet is supplied with a three-spoke leather sports steering wheel. Multifunction keys are available as an option, and the S tronic transmission features shift paddles. The switches adopt an organic, ergonomic design. The two navigation systems available use an operating logic adopted from the superior MMI concept as familiar from Audi's large car lines.

Audi offers a broad range of options for the seats. On the Ambition line, both front seats are sportily contoured. An electric four-way lumbar support is available as an option, as is heating for the front seats or all four seats.

The interior: that free, open-air feeling

The classic convertible character that the fabric top creates in the open-top A3 can also be detected in the way the interior space is used. The windscreen is as upright as on the A3 with permanent roof, creating an unobstructed, airy impression of openness – unlike many competitor concepts with a steel roof, where the windscreen lies flatter. Because the folded hood occupies little space, it has not been necessary to move the rear bench seat further forward. This leaves ample legroom at the rear, thanks in part to the long wheelbase of 2,578 millimetres.

Another of the Audi A3 Cabriolet's major strengths in everyday use is its variable luggage compartment. The rear seat backs, split 50:50, can be released from the luggage compartment. The wide, high through-loading space that is created increases the luggage capacity to 674 litres and the load area length to 150 centimetres – ample even for large items of sports equipment. In the standard arrangement the luggage compartment has an ample capacity of 260 litres, whether the hood is open or closed.

The drivetrain

The A3 Cabriolet is being built in four four-cylinder engine versions, two of them petrol and two diesels. All of them are turbocharged direct injection engines – their designations TFSI and TDI embody technological combinations that blend impressive output with high efficiency. TFSI technology demonstrated its potential over many years in the realm of motor sport – the sports prototype R8 won the Le Mans 24 Hours five times between 2000 and 2005. The Audi R10 TDI added to the string of successes in 2006 and 2007 with its immensely powerful V12 TDI.

The new A3 Cabriolet is available with a choice of two TDI engines – a combination with which Audi already established a trend in 1995; back then, the 1.9 TDI became the first diesel engine in the world to be used for powering a convertible. In the A3 Cabriolet, the smaller of the two four-cylinder engines musters up an output of 77 kW (105 bhp) and a hefty 250 Nm of torque at just 1,900 rpm from a swept volume of 1,896 cm3. The speedometer needle takes 12.3 seconds to pass the 100 km/h mark, and the top speed is 185 km/h. This diesel version uses just 5.1 litres of fuel per 100 km. The A3 Cabriolet 1.9 TDI is available with a five-speed manual gearbox.

The new 2.0 TDI with its displacement of 1968 cm3 displays the strengths of the TDI concept in an evolutionary interpretation – it runs efficiently, powerfully and very quietly. The four-valve engine, which is equipped with two balancing shafts, has been fitted with a newly developed common rail system. Its turbocharger has variable vanes for greater responsiveness and the pistons have acquired an optimised geometry that further enhances the efficiency of the combustion process.

The two-litre engine develops 103 kW (140 bhp). Between 1,750 and 2,500 rpm it generates 320 Nm of torque – enough to accelerate the A3 Cabriolet from 0 to 100 km/h in 9.9 seconds and up to a top speed of 204 km/h. The 2.0 TDI is content to clock up 100 kilometres on an average of just 5.3 litres of fuel and its emissions already undercut the limits of the future Euro 5 standard. As an option, Audi can supply the high-tech S tronic transmission instead of the manual six-speed gearbox.

Petrol direct injection: injection pressure boosted to 150 bar

The newly developed 1.8 TFSI produces 118 kW (160 bhp) and 250 Nm, the latter across an engine-speed range of 1,500 to 4,200 rpm. An adjustable intake camshaft optimises filling of its combustion chambers and two balancing shafts guarantee plenty of refinement.

Direct injection and turbo technology is the ideal combination for abundant driving pleasure and impressive efficiency. The turbocharger responds extremely fast and the four-cylinder engine is spontaneous, fleet-footed, high-revving and torquey. It accelerates the A3 Cabriolet with six-speed manual gearbox to 100 km/h in 8.3 seconds and on to 218 km/h; it accomplishes the EU driving cycle on an average of 7.3 litres per 100 km. Alternatively Audi can supply the sporty S tronic.

Technically speaking, the 1.8 TFSI is a very close relation of the 2.0 TFSI that was voted "Engine of the Year" three times in a row by an international panel of journalists. The two-litre version puts 280 Nm of torque onto the crankshaft from 1,800 to 5,000 rpm, and between 5,100 and 6,000 rpm it develops 147 kW (200 bhp). The 2.0 TFSI likewise operates with an adjustable intake camshaft and two balancing shafts, and its compression ratio of 10.5:1 guarantees high thermodynamic efficiency.

With the S tronic dual-clutch gearbox that is available alongside the six-speed manual gearbox, the A3 Cabriolet 2.0 TFSI sprints from 0 to 100 km/h in 7.3 seconds; its top speed is 231 km/h. It uses on average 7.6 litres of fuel per 100 kilometres.

The engine's power is directed to the front wheels on all versions of the Audi A3 Cabriolet; the engine versions from the 103 kW (140 bhp) upwards are fitted with a six-speed manual gearbox as standard. The S tronic combines the advantages of both automatic and manual transmission. At high loads and engine speeds, it shifts between its six gears in just 0.2 seconds without palpably interrupting the power flow.

The driver can operate the S tronic by means of the one-touch lever or, in motor racing style, using the shift paddles on the steering wheel. There are furthermore two fully automatic modes available, D for Drive (standard) and S for Sport. The S tronic operates highly efficiently and its electronic management in the automatic mode ensures that the engine runs as economically as possible at low engine speeds. Even the most painstaking of drivers could not accomplish this better.

The dynamic suspension

The light, compact fabric top lowers the overall weight and the centre of gravity of the Audi A3 Cabriolet. This helps the Audi dynamic suspension to realise its full potential.

Audi had recourse to a classic layout for the front suspension – a McPherson design with triangulated lower wishbones. The subframe on which the structure is mounted is made from aluminium. Bolted to the body, it imparts the forward structure with very high rigidity.

The precise, firm-acting rack-and-pinion steering operates with electromechanical power assistance with speed-dependent control. The system does not use energy when the car is driving in a straight line, saving 0.2 litres of fuel per 100 kilometres on average.

The four-link rear suspension represents another technical highlight. Its design principle brings major advantages in terms of handling characteristics because it registers and responds to longitudinal and lateral forces separately. Here again, a subframe connects the suspension with the body; compact coil springs and dampers provide vertical support.

All these technologies are key ingredients of the overall impact made by this sporty convertible. It is infused with the precision and spontaneity that the car delivers with every turn of the steering. The open-top A3 is sprung with subtlety and its steering functions with unshakeable calm. The self-steering behaviour remains neutral right up to a very high handling limit.

Options: sports suspension and large-dimension wheels

For the Ambition equipment line, the A3 Cabriolet is available optionally with sports suspension that lowers the body by 15 mm. The Attraction line comes with 16-inch wheels with size 205/55 tyres. On the Ambition, 17-inch aluminium wheels with size 225/45 tyres are standard. Audi can also supply four other wheel versions as options, as well as a tyre pressure monitoring system.

The brake system of the A3 Cabriolet likewise satisfies sports standards. The front discs are ventilated and have a large diameter. The pedal feel is direct and spontaneous, and the braking power can be regulated with outstanding ease. Particular emphasis was placed on reducing the braking distance when the stabilisation program (ESP) was being fine-tuned.

The equipment

The Attraction line of the Audi A3 Cabriolet already comes with a semi-automatic hood. Four electric windows and the standard daytime running lights round off the specification. The sporty Ambition line has the distinguishing features of 17-inch aluminium wheels, front fog lights and sports suspension. Inside, the sumptuous equipment includes sports seats, a driver information system, a leather sports steering wheel, a wind deflector and special inlays, upholstery and door sill trims.

The range of options for the A3 Cabriolet includes such convenient items as multifunction steering wheels, deluxe automatic air conditioning, leather upholstery, heated seats and a parking aid. Xenon plus headlights and the adaptive light for cornering illuminate the road effectively in the dark. The storage package for the interior and luggage compartment and a ski and snowboard bag further add to the practical utility of the A3 Cabriolet.

Typically for Audi, the A3 Cabriolet too features a broad range of multimedia technologies. This extends from the chorus CD radio, with four speakers, to the Bose sound system. All audio systems from the concert radio upwards include an interface on the centre tunnel for connecting up an iPod or MP3 player. Two navigation systems – with monochrome or large colour monitor – help with providing directions. For mobile telephony, Audi offers a mobile phone preparation in combination with the audio systems.

Those who are fond of very special features will appreciate the equipment lines on offer from quattro GmbH. The S line comprises an exterior package for the body and a sports package. A third option available from quattro GmbH is the Audi exclusive line.
