Audi Cross Coupé quattro concept... Q3
The way Tiguan should dress
When invited to Audi's party

Cross Coupé quattro concept: 3-dimensional headlights, with LED tech.

APN,
17th May 2007.

When it presented its Audi Cross Coupé quattro concept car at the Shanghai Motor Show (20 - 28 April 2007), the VW group was not just showing the Chinese market how important it is for the Ingolstadt brand.

China is of course Audi's third market worldwide, with 82 thousand units sold there last year, and a growth of 39% over 2005. But the larger European automotive group was also showing that like many other Volkswagen models, the coming VW Tiguan compact crossover SUV will get it's Audi version.

Just like the VW Golf has a more luxury-oriented sister known as the Audi A3, the coming VW Tiguan (end of this year), also based on the Golf platform, will get later an Audi brother expected to be called, the Audi Q3, just like its bigger brothers, the large Q7 and the coming Q5 (next year).

All that is part of Audi's announced plans to grow its worldwide sale from last year's 905 thousand units (9.2% growth from 2005), to 1.4 million unit every year. The "army" to be deployed for such an expansion will grow Audi's models number from 22 to 40 models, at an investment cost of no less than 11.4 billion Euros (from 2006 to 2011).

That's where the coming Q3, or the current Audi Cross Coupé quattro concept car fit within the larger strategy.

In more direct terms, the Audi Cross Coupé quattro comes to combine the design and dynamism of a compact premium sports car with the spaciousness and versatility of a four-seat sport utility vehicle (SUV).

The silhouette is typical Audi, with proportions and large 20" wheels pointing towards the offroad potential of the Cross Coupé quattro concept of today, and the Q3 of tomorrow. A new element is the fabric folding roof, which, when it is open, gives optimum levels of headroom and fresh air. The hood is opened and closed electrically.

Numerous electronic systems support the driver. The Audi drive select system makes it possible to pre-select three individual configurations for the engine, gearbox, steering and adaptive shock absorbers: standard "dynamic", "sport" or "efficiency" (details at the end of this page).

Dual-view - Another innovation is the MMI control panel, which is operated by a touch pad. The monitor of the system employs, for the first time, dual-view technology (concept already seen in the Alpine screen of the Jaguar C-XF concept car). The system can produce different images for the driver and front-seat passenger. These images are only visible when viewed from a specific angle (photo just above). This allows the driver to read data from the on-board computer while the front passenger watches a TV program, listening to the sound through headphones. 

Design - With a length of 4.38 m, a width of 1.82 m and a wheelbase of 2.60 m, it is only slightly larger than the A3 Sportback. The height of 1.60 m (18 centimetres higher than the Sportback) is typical of an SUV and gives the occupants a comfortable, upright seating position.

Audi Cross Coupé quattro concept car: Multifunctional rail system known since its debut in the A6 Avant.

Multifunctional rail system known since its debut in the A6 Avant.

The study has a heavily segmented side area with gently climbing shoulder line and accentuated horizontal rear end. These elements are borrowed from the new A5 coupé. A typical Audi feature is the roof, gently curved and carried on the slim A and C pillars, evoking a coupé silhouette. Also typical of a coupé are the frameless doors with fully retracting windows. The short overhangs help to make the overall proportions appear so dynamic.

The tailgate embraces both the sides and the rear, with the hinge integrated into the roof rails. The volume of the luggage compartment is 450 litres when loaded up to the edge of the window, with the multifunctional rail system that has been well proven ever since its debut in the A6 Avant.

LED for both headlights and cornering lights, and at the rear.

LED technology - Particularly eye-catching are the three-dimensional main headlights, which incorporate LED technology. The reflector dishes concentrate the light to form a powerful, uniform beam with a white tone that is easy on the eye, even on long night-time journeys. The daytime running lights, which take the form of a horizontal strip, also employ LED technology. In addition to its design qualities, this also provides for an especially low level of energy consumption.

For the first time, the Audi Cross Coupé quattro employs LED technology for both headlights and cornering lights. Here, the lens, reflector and beam deflector are integrated in a single component. LED technology is also used for the main-beam headlights.

The rear lights are deeply embedded in the body of the vehicle. The transparent red covers in a supine U-shape give a clear view of the LED technology. The area of the lights is segmented by delicate fins, indicating the very high degree of precision.

The interior - Seating is provided by individual seats in the front and a rear bench with two full-size seats. The complete seating system is upholstered in saddle brown leather. The cockpit area is heavily inclined towards the driver – typical of a modern Audi.

In the upper section of the centre console, beside the instrument dials, under the dome-shaped hood behind the steering wheel, the retractable MMI display is optimally situated in the driver's field of vision to provide driving information. A new element is the perforated trim strip in the dashboard, linking the centre console and the front-passenger area.

The perforated surface marries form and function, for it allows the air-conditioning system to provide indirect, draught-free ventilation through more than 4,600 holes.

The MMI terminal on the centre console is neat. The central control element and the six hard keys provide a simple way to operate the vehicle and infotainment functions.

Information is output on the retracting MMI monitor in the upper section of the centre console. Furthermore, selected information – for example about incoming text messages and phone calls – can be displayed directly in the windscreen via a laser projection. A further feature of this technology: electronically authorised tags or parking permission stickers can be projected in mirror image, meaning that they can be read from outside, at the edges of the windscreen, and are visible even once the vehicle has been switched off.

In addition to the MMI terminal, the Cross Coupé quattro also has a touch-sensitive sensor field (touch pad) in front of the MMI control element (opposite photo). Like on a laptop, this can be used, for example, to move image sections of the map display. The touch pad is also able to recognise characters written with your finger – even Chinese characters – and to process these as commands.

The air conditioning system also has a new control element – the touch wheel (photo just above). Pressing it with the fingertip allows the rotary movements of traditional rotary/pushbutton controls to be simulated and all functions such as temperature setting and blower speed to be controlled intuitively. An electronic driver/passenger recognition sensor "tells" the system which part of the two-zone climate control has to be adjusted. This makes it possible to do without a second, superfluous control panel.

Folding roof: view from the A pillar almost as far as the tailgate.

Opened and closed electrically, the large fabric folding roof opens up the view to the sky from the A pillar almost as far as the tailgate and across nearly the whole width of the roof, allowing almost the same degree of fresh air as that provided by convertibles.

Engine - The Cross Coupé quattro is powered by an all-new 2.0 TDI diesel engine, the first example of the new generation of four-cylinder TDI engines in the Volkswagen/Audi Group. The 150 kW (204 bhp) power plant maintains its peak torque of 400 Nm between 2,000 and 3,500 rpm. The concept car needs just 5.9 litres of diesel for 100 km.

The fuel/air mixture is prepared by a common-rail system of the latest generation, which is also employed by Audi in the V6 TDI engines. It has a high-pressure pump and common manifold (rail) for each of the four cylinders. The maximum injection pressure is 2,000 bar.

The high injection pressure provides for even finer atomisation of the fuel and thus for a better mixture and more efficient combustion. Piezo injectors allow the number of injection sequences per working cycle to be varied almost at will. A strategy that provides for both softer combustion and for lower untreated emissions – best engine acoustics and at the same time extremely low overall emissions.

The new engine is not only combined with a diesel particulate filter, but also employs the Bluetec injection system to reduce nitric oxides effectively.

The heart of the Bluetec technology is a special catalytic converter downstream of the oxidising catalyst and the particulate filter.

The second component in the system is an additional tank containing a watery solution of carbamide (urea). Small quantities of the solution, known as "AdBlue", are injected into the exhaust system. The hot exhaust gases break the solution down to form ammonia, which splits the nitric oxides into nitrogen and water. The system will remain effective for the entire service life of the vehicle.

The quattro permanent four-wheel drive system, with its Haldex clutch, ensure that traction is precisely distributed according to the situation. The electronically controlled viscous clutch provides variable power distribution between the front and rear wheels, just as it does on the Audi A3 quattro and the Audi TT.

The sporty Audi S tronic direct-shift gearbox enables the driver to execute a gear change within a fraction of a second without a clutch pedal. If he / she wants, the gearbox will make all gear changes fully automatically. And if he wants to change gear manually, he can do this with the shift paddles in the steering wheel. The newly designed selector lever with integrated control knob for selecting gear is a further development of the shift-by-wire system.

The running gear - The second pillar on which the driving dynamics are built is the running gear, with McPherson-strut front axle and four-link independent-suspension rear axle. Large 20" wheels with size 245/45 R20 tyres also contribute to driving fun and safety.

The dynamic suspension is designed to give sporty, agile handling and stability, while the electromechanical steering system comes with speed-dependent power steering. It combines optimum steering feel with low sensitivity to agitation from the road surface and reduced power consumption.

The qualities of the four-link axle are based on the functional separation of the longitudinal and lateral force absorption points. On the one hand, this allows a high degree of lateral rigidity, which favours superior dynamics and driving safety. On the other hand it also allows a high degree of longitudinal suppleness, improving ride comfort.

Individual springs and shock absorbers provide vertical support. The shock absorbers are located close to the wheels, allowing a very large load width in the luggage compartment. A tubular transverse stabiliser is secured to the subframe with highly rigid bonded-metal rubber mounts. This reduces the body's tendency to roll.

The shock absorbers employ the Audi magnetic ride system, a technology that is available in the Audi R8 high-performance sports car and in the TT. Instead of conventional shock absorber oil, a magneto-rheological fluid is used, a fluid whose viscosity is influenced by an electromagnetic field. This effect means that the shock absorber map can be changed at any time simply by applying a voltage to the solenoids.

Audi magnetic ride exploits this property to ensure that the correct shock absorber force is available in all driving situations and thus optimising ride comfort and driving dynamics. A computer equipped with sensor technology determines the prevailing driving situation in a matter of milliseconds. Here, the driver can choose between two driving programs, depending on whether he wants to drive with a sportier style – requiring low viscosity of the magneto-rheological fluid – or with a greater emphasis on ride comfort.

Brakes - Performance, low weight and better mileage are offered by the ceramic brakes. The discs are produced from a ceramic material reinforced with carbon fibres – a combination that has long been proven in the aviation industry.

The advantage of ceramic brakes over steel discs is the weight saving of some 20 kg, which improves drivability and comfort. The high level of resistance to abrasion allows a service life of up to 300,000 km. However, its most important strength is its lack of sensitivity to extreme loads.

Audi drive select - Comfort, agility or dynamic driving? Can a single car satisfy all three of these qualities? In any case, the Cross Coupé quattro drive select system makes it possible to pre-select three individual configurations for the engine, gearbox and the magnetic ride shock absorbers.

The basic setting is "dynamic" mode. This is automatically activated every time the engine is started. "Sport" mode on the other hand gives the Cross Coupé an emphatically sporty feel. The shock absorbers have a firmer setting, the engine responds more spontaneously and the S tronic gearbox moves its shift points to a higher rpm range. Ideal conditions for active driving pleasure on winding roads.

If the driver selects "efficiency" mode on the MMI, the engine and S tronic gearbox respond more gently to commands from the accelerator pedal and shift paddles. This setting is suited to relaxed driving, reducing fuel consumption and emissions. In efficiency mode, the air-conditioning system is switched off and is only reactivated if the driver so wishes.

A completely new interpretation of the cruise control system also moves the vehicle with minimum fuel consumption, allowing the set speed to drop to a certain lower limit in favour of lower fuel consumption, for example on moderate uphill stretches on the motorway.

Efficiency mode also makes use of route data from the navigation system and reduces speed early to make driving as economical as possible by avoiding the need for heavy braking when approaching a tight bend or (in conjunction with adaptive cruise control) a vehicle driving ahead.

Under normal operating conditions and combined with a forward-looking driving style, Audi drive select can make fuel savings of more than 20 percent compared to dynamic mode.
