Audi's compact Shooting Brake Concept
Soon at the 39th Tokyo Motor Show

Audi's Shooting Brake Concept features several technical innovations.

APN,
12th October 2005.

German luxury carmaker Audi will unveil at the Tokyo Motor Show (Public days from 22 Oct. to 6 Nov.) its new compact concept car, the Shooting Brake Concept .

With its powerful 250 bhp, 3.2-litre six-cylinder engine and quattro permanent four-wheel drive, the Shooting Brake Concept sprints from 0 to 100 km/h in just 6.0 seconds, and its top speed is electronically governed at 250 km/h.

The Shooting Brake Concept features several technical innovations, such as the adaptive damping system Audi magnetic ride, an evolutionary version of navigation system plus with touch screen monitor and character recognition, and the new LED headlight technology.

Design - Measuring 4.18 m long by 1.84 m wide but standing just 1.35 m tall, with a 2.47 m wheelbase (closer to the C-segment, lower medium VW Golf and Audi A3 in length, but nearer to the B-segment Polo in wheelbase dimension), the styling of the coupé reflects Audi's latest design. As on the Le Mans quattro super sports car study, the four-ring brand emblem is located above the single-frame grille, the surface of which is not interrupted by the license plate surround, either.

Upward swoop behind the rear side window, with a wide C-post, to accentuate the prominent rear end.

A further element adopted from motor sport, beneath the grille, is the aluminium diffuser, which guides the airflow beneath the car with precision.

Viewed side-on, convex and concave surfaces create a subtle interplay of light and shadow. The 19-inch double-spoke wheels originate from quattro GmbH and are a further developed version of the design created specifically for Audi's current top sports car, the RS 4.

One new element in the portfolio of design features is the upward swoop behind the rear side window. This, together with the wide C-post, accentuates the prominent rear end. The horizontal rear lights, extending well round to the sides, accentuate the horizontal divide across the rear end of the vehicle. The luggage compartment lid itself extends well up into the roof surface. This permits a wide opening angle and optimum access to the luggage compartment.

Beneath the flush, integral bumper there is a large-area diffuser as at the front, to channel the airflow beneath the vehicle such that drag is minimised and surface grip enhanced.

Low seat position with high centre console.

Inside, the low seat position is typical sports car style, with the high centre console and the clear, expansive composition of the instrument panel. The short sports-style gear lever with its tactile knob, together with the wide armrests in the doors and the pedals with aluminium-rubber surface, combine form and function with unprecedented ergonomic perfection.

The multifunction steering wheel with flattened underside is a counterpart to the wheel installed in two of the most alluring Audi sports cars ever built – the Le Mans quattro study, and the RS 4.

Above the centre console, two circular air outlets with star-pattern slats bracket a chronograph that can display information in either analogue or digital form, as preferred. This technology uses an organic polymer material that improves presentation and ease of reading.

Compared with the conventional liquid crystal displays (LCD), an organic light emitting diode (OLED) monitor is substantially easier to read.

Compared with the conventional liquid crystal displays (LCD), an organic light emitting diode (OLED) monitor is substantially easier to read, above all with the sun shining on it and when viewed at an angle. The content displayed on the monitor can still be made out from an angle of 170 degrees. Other advantages of OLED are its shallow installation depth and very short response times, as well as much lower energy consumption than LCD displays.

The MMI terminal of the DVD radio and navigation system plus, with optical and acoustic route guidance, has been redesigned. The ergonomically optimised architecture of keypad and display is inspired by the Multi Media Interface configuration in the Audi A8. Here, the system features an array of new functions such as 3D screen navigation with touch screen monitor and character recognition that permits detailed inputs using a PAD pen.

The luggage compartment of the Audi Shooting Brake Concept provides a capacity of 255 litres with the rear seat back upright and as much as 730 litres with the seat back folded down.

The steering column is adjustable in reach and height as well as the driver's seat with the same adjustment options.

Engine and transmission - The engine is a transversally installed 3.2 litres V6 engine, already known in Audi's A3 and TT car lines. Maximum output is 184 kW (250 bhp) at 6,200 rpm, and the torque range peaks at 320 Nm between 2,500 and 3,000 rpm. The gearbox is a closely spaced 6-speed gearbox, enabling it to accelerate from 0 to 100 km/h in just six seconds, on the way to a governed top speed of 250 km/h.

The Shooting Brake Concept is equipped with quattro permanent four-wheel drive. A hydraulic multi-plate clutch varies the distribution of power between the front and rear wheels.

Chassis - Suspension adopts McPherson strut layout at the front and a new four-link independent suspension at the rear, with large 19-inch wheels with size 245/40 R18 tyres.

An innovative technology is used for the shock absorbers: Audi magnetic ride. Instead of the conventional damper fluid, a magnetorheological fluid is used – in other words, a fluid whose viscosity can be influenced by an electromagnetic field (a technology already known in some models of General Motors' Cadillac and Chevrolet brands). This effect enables to damping characteristic to be influenced electronically at will by applying a voltage to the electromagnets. The driver can choose from two driving programs: sports or comfort.

The Audi Shooting Brake Concept features ceramic brakes. Compared with conventional steel discs, these not only last four times longer, but also offer high braking performance, even when driving at the limit, as well as maximum resistance to fading.

LED headlights and tail lights.

Steering is electromechanical with speed-dependent power assistance.

Other technical innovations lie beneath the covers of the headlights and rear lights. The design of the three-dimensional main headlights, using LED technology. Reflector shells arranged concentrically one behind the other each concentrate the light from one diode, producing a high-luminosity, even form of driving light.

By contrast the high-beam headlights, located on the inside, are blossom-shaped. The indicator lights, in the form of narrow light strips, delineate the lower edge of the headlight housings and the exterior mirrors, providing prominent signals and original visual accents. The daytime running lights naturally also use LED technology, the merits of which include particularly low energy consumption, over and above their attractive design.

The rear lights have transparent red covers to provide a clear view of the LED technology. The diodes cast their light forwards onto the reflector, which distributes it back to the rear through a mask in the shape of a double cloverleaf.

New navigation system - An enhanced version of the DVD screen-based navigation system plus offers special operating functions and a new screen presentation. Audi uses touch screen technology for the first time here. The driver can activate the basic architecture of the MMI screen directly by touching the function panels in the display.

The new system generation moreover permits operation of the navigation menu by direct input, e.g. of destinations, via the monitor. Instead of having to compose them one letter at a time from the menu, the driver can simply write them on the monitor with their finger. Alternatively, a remote control with pressure-sensitive surface can be used to make inputs, as on a PDA computer. The input monitor pops up out of a slot beneath the centre display at the push of a button.

The special feature is that the system is not only capable of reading in handwriting, but can also identify a wide variety of scripts. The computer is equally able to read the conventional Latin alphabet and Japanese characters.

Another new aspect is the scope provided for choosing between two different navigation modes. Those who prefer the "Tour" mode can view the route on the monitor from a three-dimensional bird's-eye perspective. The driver can take photos of destinations with a camera at the front of the car and store these as visual route markers.

Activating the "Sport" mode displays optical information above all via the central display in the instrument cluster. As well as spoken instructions, there are direction arrows to point the way. Again in the "Tour" mode, the driver can call up a further option that acts like an electronic rally co-pilot and makes the journey an end in itself: whenever the driver feels the urge to drive along a particularly challenging, winding route, they can call up an appropriate itinerary from the computer. While following the proposed route, as well as receiving directions they are then advised on the best gear to engage and the speed at which to take the next bend.
