Sheer sportiness, high power reserves plus a stirring driving experience – cue the new TT Roadster from Audi. The open-top two-seater, available in two engine versions, has retained all the strengths of its successful predecessor and added even more emotion, performance and dynamism. It is a sports car built to appeal to all the senses.
Audi offers a choice of two engines for its new TT Roadster. The 3.2-litre V6 power unit generates 184 kW (250 bhp) and is coupled to the quattro drive system as standard. The 2.0 TFSI engine, which blends turbocharging with petrol direct injection technology, delivers 147 kW (200 bhp) to the front wheels. Both model variants can be ordered with the innovative S tronic dual-clutch gearbox as an alternative to the standard six-speed manual shift.
The chassis of the new Roadster is also built for impressive sporty performance. Its highlight is Audi magnetic ride, the optional suspension damping technology that allows drivers to choose between an uncompromisingly dynamic ride or more comfort-orientated characteristics.
To mirror the puristic character of open-top motoring, the boldly styled body is crowned by a lightweight cloth hood. The TT Roadster 3.2 quattro comes as standard with a quick-action, fully automatic softtop which is available as an option for the 2.0 TFSI at a price of €1,015.
Despite its lavish specification, the new Audi TT Roadster will be priced similarly to the outgoing model. It will be launched in Germany in spring 2007 with prices starting from €33,800 (incl. 19 % VAT).
The experience of dynamic movement, the fascination of open-top driving – the new Audi TT Roadster is a sports car built to appeal to all the senses. In its second generation, the open-top two-seater has become even more emotionally charged. Beneath the charismatic design of its exterior resides the full array of advanced technology of the Audi brand.
The exterior design
Audi created a real stir in the late 1990s in unveiling what was at that time an entirely new range of sports cars. The TT, appearing in 1998 as the Coupé and in 1999 as the Roadster, was visually a sensation. Their common design became established as an icon of automotive design because it pursued the ideal of pure geometry. Its core motifs were the semicircles of the wheel arches and the curves of the roof line and the front and rear end. This timeless architecture lent the Audi TT Coupé and TT Roadster the character of a total driving machine and simultaneously gave the development of the entire brand decisive momentum.
Cautiously managed evolution: the styling
In the case of the new TT Roadster, Audi has respectfully and attentively developed and nurtured this genetic code. Unlike the Coupé, where the geometrical shapes merge dynamically with one another, the design of the open-top sports car comes across as strongly geometrical, as on its predecessor – the tail end and hood are clearly distinct entities.
The panelled body, accounting for two-thirds of the height, looks poised and powerful. The convex and concave curves of its surfaces accentuate the character of an athletic sculpture straining forward.
The wheel arches enclose wheels 16 or 17 inches in diameter, depending on the engine version, complete with striking rim designs. The tyres have grown in size to 225/55 R 16 and 245/45 R 17.
The tornado line beneath the body’s shoulder and the strikingly ascending dynamic line above the sills create the impression of a more elongated body. The legendary aluminium tank cap above the rear right wheel now features a cross-bar bearing the TT logo. The two rollover bars are angled slightly forwards, and their elegant aluminium trims have round cross-sections.
The front end of the new TT Roadster has acquired a charismatic expression. Its defining element is the single-frame radiator grille surrounded by a narrow chrome strip, with a high-gloss black instead of titanium grey finish on the V6 models. The slits beneath the grille and the large air inlets, in front of which the standard front fog lights are located, hint at the potential of the engines. Starting at the single-frame grille, two pronounced contours extend across the front lid to the A-posts.
A captivating feature: "winged" headlights
The lights sloping to a point – with chrome-look trims that are standard on the V6 versions as well as in conjunction with xenon lights, and optional on the 2.0 TFSI – underscore the presence of the TT Roadster. Reverse-curve plastic elements below the tubes, known as the "wings", accentuate the spatial effect. Instead of the halogen lights, xenon plus headlights that can be combined with daytime running lights are available as an option (standard on 3.2 quattro). Adaptive headlights with dynamic cornering light are a further option.
At the rear end of the new TT Roadster, the large exhaust tailpipes, diffuser and centred rear fog light serve as reminders of the performance of the Audi brand in motor sport. There are likewise tubular reflectors at the rear, appearing to hover inside their casings by virtue of their visual depth. Rectangular shields on the reflectors mean that other drivers following on behind perceive angular light rings.
On the TT Roadster with four-cylinder engine, the light housings are red, and on the V6 quattro they are of a dark colour (optional on 2.0 TFSI).
The spoiler of the new Audi TT Roadster is unobtrusively integrated into the contour of the luggage compartment lid. When the car reaches a speed of 120 km/h, the spoiler is automatically extended out by an electric motor, thereby improving the downforce on the rear axle. It is automatically retracted again when the speed falls below 80 km/h. The driver can also operate it via a switch.
The drag coefficient of the Audi TT Roadster is only 0.32, compared with 0.34 for the final version of the predecessor model. The frontal area has grown in size from 1.99 m2 to 2.09 m2, but the overall drag of the new two-seater nevertheless undercuts the figure for its predecessor. Thanks to engine encapsulation and the body’s ASF design, its underbody is smooth throughout almost its entire length. Lift has been reduced by 50 percent at the front axle, and by 40 percent at the rear axle.
The engineers implemented cutting-edge technology in the development work performed in the wind tunnel. The facility is equipped with a belt that runs at the speed of the wind, allowing the wheels to rotate when the measurements are being taken. The balanced aerodynamic properties provide the basis of this open-top sports car’s excellent road behaviour and stability right up to top speed.
The dynamic impression that the new two-seater creates also stems from its modified proportions. Compared with the previous model, the two-seater is 137 mm longer and 78 mm wider, but only 8 mm taller. It is now 4,178 mm long, 1,842 mm wide and 1,358 mm high. The new TT Roadster’s wheelbase is 2,468 mm (+ 46 mm). This growth has by and large been translated into increased space inside: it has become measurably more spacious and has a more airy feel.
The soft top
Audi made a conscious decision to keep the cloth hood for the new TT Roadster. The soft top concept fits in perfectly with the philosophy of puristic open-top motoring and also offers a number of benefits over a folding steel hard top.
The cloth hood, incorporating reinforcements made from steel and aluminium as well as a large glass rear window, has a very lightweight construction – not only does this reduce the overall weight of the TT Roadster, it lowers its centre of gravity too. It sleekly blends in with the car’s lines and takes up only a small amount of space when folded down. Thanks to the new Z-fold, the front section of the roof lies on top of the cloth like a cover. It locks into place to lie flush with the body, dispensing with the need for a tonneau cover. The soft top is available in the colours black and dark grey.
The body of the new TT Roadster is built at the Ingolstadt plant in line with the ASF principle, using an innovative composite structure of aluminium and steel; like its predecessor, the painted bodyshell is then forwarded by rail for final assembly at the Györ plant in Hungary. ASF stands for Audi Space Frame, the ground-breaking aluminium technology that the brand developed at the start of the 1990s.
The supporting structure of the Roadster body is made of extruded aluminium sections and die-castings; a large number of aluminium sheet panels form a positive connection and perform a load-bearing role within this structure. The individual components have various shapes and cross-sections – like the bones in a human skeleton, they combine best possible function with lowest possible weight.
In the body of the new TT Roadster, Audi has supplemented ASF technology with high-strength steel, which accounts for 42 percent of the overall weight. Steel components are used primarily at the rear of the floor assembly. The reinforcing bulkhead that plays a key role in the Roadster, as well as the doors and rear lid, are likewise made from steel. The developers were thus able to achieve an optimum distribution of axle loads and consequently dynamic handling.
The bodyshell of the TT Roadster weighs 251 kg; were it built entirely of steel, it would be 45 percent heavier. Unladen, the 2.0 TFSI tips the scales at a mere 1,295 kilograms.
Central zones of the body: the cast nodes
The percentage of wrought aluminium components in terms of the overall body weight are as follows: 22 % of sheet, 18 % of castings and 18 % of extruded sections. Castings are deployed primarily where high forces are introduced locally and where multi-functionality is required. A prime example is the A-post node – a high-tech component that connects the longitudinal member, sill, A-post and windscreen cross-member.
On the new TT Roadster, a large proportion of the extruded sections are made from innovative aluminium alloys that exhibit superior strength and therefore help to cut the weight even further. The new-style ASF features properties that are ideal for a sports car. Compared with the already very good predecessor, its static torsional rigidity has risen by over 100 percent.
The vibrational comfort on board is also exceptional; this is all thanks to high local rigidity at the points of introduction of the frequencies, improved soundproofing of the body and the specific design of the metal-panelled areas. The drivetrain and suspension, too, are acoustically optimised.
The new Roadster TT also sets new standards in terms of crash safety. The longitudinal members at the front end are made of extruded aluminium sections and castings. In conjunction with the front cross-member and the subframe, which is bolted to the forward structure at six points, this assembly reduces and distributes the energy that acts in a head-on collision.
At the rear end, there are large-volume members to protect the passenger compartment. High-strength aluminium profiles in the doors and robust side sections resist the worst of a side impact. Transverse extruded sections reinforce the floor of the passenger compartment. The windscreen frame, which is reinforced by a high-strength steel tube, and the rollover bar protect the passengers in the event of a rollover.
Both front airbags, which are activated in two stages depending on the severity of the impact, receive their signals from an early-responding up-front sensor located at the front of the vehicle. The belt tensioners and belt force limiters protect the driver and passenger, and a special mechanism pivots the pedals away from the driver’s legs. Large-size head and thorax side airbags are integrated into the seat backs. In a rear-end collision, the Audi backguard system uses the head restraint to support the back of the head.
The dynamic exterior appearance is carried through into the interior of the new TT Roadster. It has the same advantages as a made-to-measure suit: the driving area, the horizontal edge of which echoes the tornado line of the body, is perfectly tailored to the driver’s requirements.
The centre console, now with three circular air outlets instead of the previous two, is turned slightly towards the driver and rests visually on a wide centre tunnel. The short gear lever knob and the rotary controls for the automatic air conditioning (standard on the 3.2 quattro) have a substantial look that is entirely in keeping with the TT tradition.
The instrument cluster is located beneath a round instrument panel hood that can be supplied trimmed in leather as an option. The two scales for speed and revs, embedded deeply inside tubes, are another characteristic TT feature. They are complemented by a large digital speedometer in the driver information system display. The new three-spoke sports steering wheel, which is adjustable horizontally and vertically, fits snugly in the hands.
Its thick rim, trimmed in high-grade Nappa leather, is flattened at the bottom, reminiscent of the Audi RS 4 and the new R8 mid-engine sports car. As an option, the multifunction sports steering wheel can be supplied with convenient controls for the radio and telephone, and there are two shift paddles on the versions with S tronic. The driver’s and passenger’s sports seats offer a very deep, sporty position allied to high comfort and firm lateral support. They now have a greater adjustment range; a four-way lumbar support and electric adjustment of the entire seat are available as options.
Superlative finish has already become a hallmark of Audi. The rings on the air outlets and various controls such as the door openers are finished in aluminium. The carpets are made from high-quality pile carpet and there are aluminium door sill trims in the side sills. The gear lever gaiter is made from leather – on the 3.2 quattro, the handbrake lever, additional armrest on the centre tunnel and pull handles on the doors are also trimmed in leather. Three optional leather packages complete the range.
The TT 2.0 TFSI has cloth seat upholstery, and the 3.2 quattro a Leather/Alcantara combination complete with seat heating. For custom specifications, Audi offers the leather grades Valetta, Fine Nappa, Leather/Alcantara and Impulse. The Impulse equipment and trim, available exclusively in chennai brown and with strikingly contrasting seams, rose to cult status in a similar form on the previous model as the moccasin-like Authentic leather.
Sporty and practical: the load-through hatch with removable ski bag There are two large, practical door compartments and two cup holders inside the car as standard. A storage package comprising three nets and four compartments – beneath the seats and in the rear bulkhead – is available as an option. Sporty customers will moreover appreciate a load-through hatch complete with removable ski bag for the rear bulkhead.
It accommodates two pairs of skis up to 1.90 m long – this practical feature is unique in the roadster segment. The luggage compartment, too, has benefited considerably from the body’s larger dimensions. It has grown from previously 180/220 litres to a capacity of 250 litres. In a new departure compared with the previous model, the capacity is the same on both the front-wheel-drive 2.0 TFSI and the 3.2 quattro. It remains constant irrespective of whether the hood is open or closed. -----
The drive train
The new Audi TT Roadster starts out life with a choice of two transverse petrol engines – one a four-cylinder turbo, and the other a naturally aspirated V6. Both power units provide it with impressive pulling power, top performance values and correspondingly dynamic road performance.
- 2.0 TFSI developing 147 kW (200 bhp), 280 Nm
- 3.2 V6 developing 184 kW (250 bhp), 320 Nm
The 2.0 TFSI
The direct-injection four-cylinder turbo engine badged as the TFSI has a displacement of 1,984 cm3. In recognition of its innovative technical package, an international jury of automotive specialists voted it the "Engine of the Year" in both 2005 and 2006. The TFSI engine combines the FSI petrol direct injection system developed by Audi with a turbocharger – an ideal combination.
FSI petrol direct injection has already demonstrated its superiority in terms of performance and efficiency not only for road driving, but also in particular measure in the world of motor sport. From 2001, the Audi R8 sports prototype powered by FSI engines notched up numerous overall wins in endurance races, including five wins in the legendary Le Mans 24 Hours. FSI technology involves injecting the fuel at between 30 and 110 bar from an accumulator, similar to the common rail of a diesel engine, directly into the combustion chambers.
Flaps in the intake tract moved by actuating motors induce a rolling type of movement in the incoming air. The injectors atomise the fuel into this "tumble" inside the combustion chambers. Because the fuel’s evaporation draws heat out of the combustion chambers, petrol direct injection overcomes the fundamental problem faced by all turbocharged engines – the high amount of heat generated, and the engine’s resulting tendency to knock, hitherto necessitating a reduced compression ratio. For the TFSI, Audi has been able to achieve an exceptionally high compression ratio of 10.3:1, decisively improving the thermodynamic efficiency of the engine.
The continuously variable intake camshaft in the TFSI cylinder head contributes towards optimum cylinder filling across the entire engine-speed range. The lightweight pistons are made from a highly heat-resistant aluminium alloy with a piston-ring carrier zone featuring a grey cast iron reinforcement.
Two balancing shafts running at double the speed of the crankshaft compensate for the second-degree inertial forces, thus producing a high level of refinement in the engine’s running. The turbocharger’s turbine housing and the exhaust manifold are made from a single grey cast iron component. The charge-air intercooler is located immediately ahead of the engine’s radiator, with the result that it also catches the airflow of the cooling fan.
Cooling of the compressed air increases the charging efficiency of the cylinders. The two-litre TFSI is a real all-rounder. It responds spontaneously to the accelerator, revs up eagerly and delivers ample pulling power even at very low engine speeds. The undersquare engine puts 280 Nm of torque onto the crankshaft even at engine speeds as low as 1,800 rpm, and is able to keep this high level of torque constant up to 5,000 rpm. The nominal power output of 147 kW (200 bhp) is available between 5,100 and 6,000 rpm.
The Audi TT Roadster 2.0 TFSI accelerates to 100 km/h in 6.5 seconds (in the version featuring S tronic) and on to a top speed of 237 km/h. It clocks up 100 kilometres on an average of 7.8 litres of premium-grade fuel, irrespective of transmission type.
The 3.2 V6
Even more power is on tap from the V6 engine with its 3,189 cm3 capacity. Its peak torque of 320 Nm is available at engine speeds as low as 2,500 to 3,000 rpm, and its output of 184 kW (250 bhp) at 6,300 rpm. Many aspects of the six-cylinder engine have been revised compared with the version in the previous TT Roadster model.
The reconfigured mapped characteristic ensures that it responds to the throttle even more spontaneously and with more "bite" in all engine speed ranges.
This undersquare engine is fascinatingly free-revving and sonorous, accentuating in particular the intake sound, whereas the sound produced by the TFSI is primarily based on the exhaust spectrum.
The V6 owes its suitability for transverse installation to its extremely narrow included angle of just 15 degrees between the cylinder banks; both banks share the same cylinder head. Both camshafts can be adjusted continuously, for more effective cylinder filling – by 52 degrees at the intake end and 42 degrees at the exhaust end.
The variable intake manifold optimises cylinder filling still further. The new Audi TT Roadster 3.2 quattro with S tronic sprints from a standing start to 100 km/h in 5.9 seconds. Its top speed is 250 km/h (governed), and its average fuel consumption 9.5 litres per 100 km.
The sporty chassis has undergone complete redevelopment for the new TT Roadster. Its chief features are the complex four-link rear suspension, wide track widths, elastokinematics that have been heavily reworked, plus large wheels. The 2.0 TFSI rides on 16-inch and the 3.2 quattro on 17-inch alloy wheels. The wheels may be specified with run-flat capabilities as an option.
The front wheel suspension, which is linked to a separate subframe, has a McPherson construction that has been refined by the use of lightweight aluminium components. The electromechanical power-assisted steering combines a direct ratio with sensitive precision.
The construction of the four-link rear suspension, which also operates using a subframe, separates the coil springs and the shock absorbers from one another. The longitudinal links – which have a relatively soft set-up for enhanced ride comfort – absorb the propulsive and braking forces, while the rigid connection of the three transverse links for each wheel allows them to direct the lateral forces into the bodyshell with great precision.
The redeveloped electronic stabilisation program (ESP) has been optimised for a sporty driving style and to help produce the steering balance of the TT Roadster, which varies between neutral and slight understeer. If necessary, the brake assist system takes action to ensure that the four large disc brakes build up maximum braking power as fast as possible.
The optional Audi magnetic ride adaptive damping system is a high-tech feature that is unique in the roadster segment. At the push of a button, drivers can choose between either an extra-comfortable or a decidedly dynamic suspension set-up. Circulating inside the shock absorber struts is a special fluid containing minute magnetic particles. Applying a voltage to this fluid alters its viscosity – and therefore the damping characteristics – within milliseconds.
The rear suspension
The new four-link rear suspension, also new, represents a further major technical breakthrough. It is used on both the quattro and the front-wheel-drive version, the only difference being the subframe, which is made from aluminium instead of sheet steel on the quattro, and accommodates the additional differential. The rear track measures 1,558 millimetres, an increase of 45 mm on the previous model.
The four-link principle realises major benefits in terms of driving dynamics, because it separates the functions of cushioning of longitudinal and transverse forces. The longitudinal links absorb the driveline and braking forces, and their relatively soft mounts assure good ride comfort. On the other hand, the three wishbones per wheel – the spring link, the upper wishbone and the tie rod – are attached very rigidly to the subframe, for optimum handling characteristics. As on the front axle, the subframe is bolted firmly to the body.
All links are made from high-strength steel grades. Separate, compact springs and shock absorbers provide the necessary vertical support. The progress that this configuration represents really can be felt. The new TT Roadster responds with precision to steering movements, with only minimal movement of the body. It turns spontaneously and takes all manner of bends at high speed; its high limits of handling are heralded by a slight understeering response. The new TT Roadster features sporty settings.
Wheels and brakes
The TT Roadster 2.0 TFSI features 16-inch cast aluminium wheels, fitted with 225/55 R 16 tyres as standard. The 3.2 quattro is equipped with forged 17-inch lightweight alloy wheels, fitted with size 245/45 R 17 tyres. There are in addition three designs of 18-inch wheels in the range; quattro GmbH can even supply wheels measuring up to 19 inches in diameter. Run-flat tyres with reinforced side walls are available for all 17 and 18-inch wheels.
As a further option, Audi can supply a refined tyre pressure monitoring system that identifies precisely which wheel has suffered a puncture. The brake system has been specially matched to the requirements of a sports car. Newly developed brake pads on the front wheels generate around 15 percent more friction. On the four-cylinder version, the front discs are ventilated and measure 312 mm in diameter; the large rear discs have a diameter of 286 mm.
The 3.2 quattro features four ventilated discs, in diameters of 340 mm at the front and 310 mm at the rear. The brake calipers, painted black as standard, are also available in the colour dark grey as an option. Thanks to the new ratio of the brake servo, the pedal response is more direct and spontaneous, and braking power easier to regulate. There is also a brake assist system to aid the driver in critical situations.
Particular emphasis was in addition placed on reducing the braking distance when the new stabilisation program was developed. The ESP has moreover been optimised for a sporty driving style and subtlety of control. Its new functions include dry-braking the discs in rain by repeatedly applying the pads briefly to the discs. Both engine versions of the TT Roadster can be supplied optionally with Audi magnetic ride – this new damping technology overcomes the traditional conflict of objectives between comfort and handling characteristics.
A continuously adaptive system, it repeatedly adjusts the damping characteristics to the new situation within a matter of milliseconds. The shock absorber pistons contain a special magneto-rheological fluid – a synthetic hydrocarbon oil in which microscopically small magnetic particles measuring between three and ten microns are enclosed. When a voltage is applied to a coil, a magnetic field is created in which the alignment of the particles changes. They arrange themselves transversely to the direction of flow of the oil, thus inhibiting its flow through the piston channels. This instantaneously alters the characteristic, much faster than is possible in conventional adaptive dampers.
Two programs: comfortable or dynamic
The control unit, supplied by complex sensing technology, constantly monitors the properties of the road surface and the driver’s style. The driver is able to activate the normal position or the Sport mode via a button on the centre tunnel. In the normal mode – when the oil is more viscous – the TT Roadster rolls smoothly; this is ideal for long-distance driving or uneven road surfaces.
In the Sport mode, by contrast – when the oil is less viscous – it reveals an extremely dynamic character that is manifested by a firm grip of the road surface. From the very moment the steering is turned, rolling movements are suppressed even more effectively than in the basic suspension setting, and the steering response is further improved. The specific stabilisation of each individual wheel further optimises the self-steering behaviour, resulting in a driving feel reminiscent of a go-kart.
The new Audi TT Roadster is priced at a similar level to the previous model – the 2.0 TFSI costs EUR 33,800, and the 3.2 quattro EUR 43,800 (incl. 19 % VAT). The standard specification reflects the character of the open-top two-seater: it is copiously equipped and offers every creature comfort that even sporty drivers could wish for. The first external sign of the new Audi TT’s dynamic potential is provided by its large aluminium wheels. They measure 16 inches across on the 2.0 TFSI and 17 inches on the 3.2 quattro.
The V6 sports a black high-gloss radiator grille and specially designed headlights and rear lights, with factory-fitted xenon plus headlights including daytime running lights. Front fog lights and electrically adjustable exterior mirrors – including heating on the V6 – are part of the standard specification for both versions. One distinguishing feature of the 3.2 quattro is the individual tailpipes on the left and right, whereas the 2.0 TFSI has both tailpipes grouped as a pair on the left-hand side. The rollover bars with aluminium trims on the reverse side are characteristic features of both versions.
Inside both engine versions, the driver information system shows information for the on-board computer on its display, and also shows the road speed in digital numbers. Electric window lifts, central locking with radio remote control and the new "chorus" radio provide a high standard of comfort and convenience for everyday use of the TT. On both engine versions the sports seats can also be height-adjusted, and the sports steering wheel is trimmed in Fine Nappa leather.
The TT Roadster 3.2 quattro has heated seat upholstery in Alcantara/Leather, and operating elements such as the door pull handles, the handbrake handle and the armrest in the centre console are in addition trimmed in leather. Its automatic air conditioning system regulates the heating and ventilation depending on the sun’s position. Various controls and trims on the V6 have a resplendent aluminium finish.
Leather trim is available for the interior of the new TT Roadster in a choice of Valetta, Fine Nappa, Leather/Alcantara (standard on 3.2 quattro) and Impulse. Customers in addition have three leather packages to choose from. A four-way lumbar support, electric 12-way adjustment and seat heating (standard on the 3.2 quattro) are available as options. The storage package includes two nets and four additional compartments, two under the front seats and two in the rear wall behind the seats. There is a further package comprising various aluminium-look controls and inlays. There are more options which enhance safety on board the TT Roadster.
The headlight washer system (standard on V6 and with xenon plus) maintains a clear view, and the acoustic parking aid Audi parking system facilitates reversing into a parking space. The anti-theft alarm is combined with interior monitoring, and an Isofix mounting for a child’s seat is available for the passenger seat. The cruise control makes driving lengthy stretches of motorway an altogether more relaxing affair. The same applies to the leather multifunction steering wheel, which incorporates buttons for operating the radio, speech control system and telephone. On the versions with S tronic, there are also the shift paddles for the transmission.
The size 17 and 18 inch tyres are also available as versions with run-flat properties on the new TT Roadster. Intelligent tyre pressure monitoring is available for the standard tyres. There are aluminium winter wheels in the standard dimensions from 16 to 18 inches, and summer wheels measuring up to 19 inches in the S line and exclusive range.
The new TT Roadster comes with a choice of three solid paint colours as standard, with ten metallic and pearl-effect colours available as options. A special lights styling package incorporates chrome-look trims for the headlights and black rear-light inserts (standard on the 3.2 quattro and in conjunction with xenon plus). Audi is able to supply the headlights of the new TT
Roadster in two different versions: xenon plus lights with integral daytime running lights (standard on the 3.2 quattro), and a xenon plus system that incorporates adaptive light, the dynamic cornering light system. A combined light and rain sensor is also available as an option.
The S tronic dual-clutch gearbox and the adaptive damping system Audi magnetic ride guarantee the TT Roadster a unique competitive position. Customers looking for other dynamic options such as sports suspension with steel springs will find them in the S lines and in the Audi exclusive range from quattro GmbH.
New technologies: the infotainment
Audi is presenting a new generation of equipment for its infotainment technology. The three new audio systems have a double DIN frontage format. Their VHF reception has been substantially improved and the controls made simpler: around the large-format three-line display are six softkeys which perform different functions depending on which menu is selected.
The standard-specification "chorus" radio features a single CD drive. The "concert" model is able to play MP3-coded tracks, and the top-of-the-range "symphony" model incorporates an MP3-enabled six-disc CD changer. High-quality sound systems ensure audio enjoyment.
The "chorus" radio supplies four passive speakers with an output of 40 watts. On the other two models, a digital five-channel amplifier produces an output of 140 watts, spread among nine active speakers. The highlight is a surround sound system from the specialist Bose: twelve high-performance speakers, including one subwoofer, are supplied with a total output of 255 watts from eight separate channels.
Customers have a choice of two radio and navigation systems in the new TT Roadster. The operating logic for both systems shares the exemplary MMI concept from the large Audi model series, and they can be combined with other modules such as a CD changer or mobile phone preparation. The large system can also play MP3-coded songs on CDs and memory cards. The new TT Roadster can, if desired, be equipped with a mobile phone interface with Bluetooth technology; the telephone can also be operated via the multifunction steering wheel or the navigation systems.
Like its predecessor, the new Audi TT Roadster has considerable potential to win over new customers. Most of its customers will be young, dynamic climbers aged between 30 and 45 – the youngest customer group for Audi and indeed the field of competitors. They will have a high level of education and professional qualifications.
The first generation of the TT Roadster was already extremely popular with women. That is likely to remain the case with its successor. Buyers of the new TT Roadster will attach particular importance to lifestyle and leisure. They regard their car as a statement of their personal vitality, and feel a strong emotional bond with it. For them, driving a roadster is a tangible expression of freedom and independence.
