Touching the senses

October 2003
By Nargess Shahmanesh-Banks    

Sitting inside an Audi there is a feeling that none of our senses: touch, sight, sound and smell have been ignored. Instead they are perfectly and pleasantly co-ordinated. In the top-end A8 for instance, so much thought has gone into the use of materials, that the wood is not just wood, but toned to the right level, and chrome is not used simply in an ornate fashion, but as a functional object. Even the control buttons seem perfect inside an Audi. Nargess Shahmanesh set out to find out just how does the carmaker do it.

Even when it is on a concept car, such as this Le Mans quattro concept car shown at the IAA ln September, 2003, Audi's interior design detail is still apparent

The Le Mans quattro, Audi's concept car shown at the Frankfurt Motor Show in September 2003, may go into production according to a company spokesman. Melinda-June Jenkins, Audi senior designer in colour and trim, says she hopes so. "If you ask all the people who worked on the car, they would hope that it will become a production vehicle." Peter Zieten, Head of Audi colour and trim interrupts adds that it has not necessarily been decided yet and that the carmaker needs to examine the economical implications of making such a car, before giving the go ahead. "We like to create concept cars, but the important thing is to create cars that we can make money from," he says.

The TT concept, launched a few years ago at the same show received such an incredible reaction from the public that the carmaker showed no hesitation in creating the car. The car, it seems set the benchmark for Audi show cars. For the Le Mans, there will now be much discussion between the management, adds Zieten.

This is a high-performance sports car, a vehicle that could be said to have inherited the genes of the Audi R8, three-times winner of the Le Mans 24-Hours race. 1.90 metres wide, only 4.37 metres long and 1.25 metres high it reflects the proportions of a pure sports car. A wheelbase of 2.65 metres accommodates a spacious cockpit and there is a longitudinally installed V10 'biturbo' engine with FSI direct fuel injection behind it.

The Le Mans has a driver-focused interior architecture. In fact this seems to be the growing trend amongst carmakers. For instance Volkswagen's new brave Concept R is very much a driver oriented machine, where everything inside points towards the driver. The driver can be regarded as an integral element of a cockpit bordered by the fascia, a high centre console and the instrument panel above it, which is angled towards the driver.

Form follows function inside. The purist principle runs through to the choice of materials that creates the functional atmosphere, although the materials used in the show car aren't necessarily viable for the production model. Instead some aspects are experimental for Audi. Zieten explains: "This is a new car for Audi and we have tried to create new materials." The more traditional leather and wood has been replaced by new concepts. The designers have looked to materials used in sports car to find new materials, but have given it another interpretation. "For the production version we will need a lot of time to test new materials for durability and safety," he adds.

Jenkins adds that this has been an unusual experiment for Audi. "This is the first show car to have been built without any leather. There are special fabrics on the seats. The material used is what you see or know from boat interior design, or from technical products." Zieten jokingly calls it ordinary plastic, but Jenkins says it is more like high tech fabrics. "These are materials that are often used in fashion, maybe sports fashion, so it is unusual to put them in the car," she adds. Various materials have been woven into each other and laminated to create textures resembling rubber and industrial strength material. The result is quite forwards looking without seeming 'space age' or too sci-fi, she adds.

The dark, or 'technically coloured' shades used inside add a visual link with motor sport. This also gives an impression of professional functionality and ergonomic efficiency. Colour, after all plays on the psyche.

The metal parts inside the Le Mans are tinted grey to create an illusion of not being too obviously aluminium. Again this creates, as Jenkins points out, a less manufactured feel. This is a modern interpretation of luxury for Audi, but this is very much something to be used in a niche sports car like this. The footwells and footrests are fully painted to yield a surface finish that is repeated inside the boot and the engine compartment as well.

Individual areas are clearly distinguished by the use of different materials: the fascia, for instance, uses a high-grade semi-transparent woven material with a network structure; this is also to be found on the outside of the seat shells. For precision operation and to make them pleasant to the touch, the controls are of rubber and aluminium.

A non-slip material with the appearance of Neoprene is used for the shoulder area of the seat shells. These are hinged in the lumbar region and have the seat cushions upholstered with a sporty and futuristic high-tech weave.

There are well-positioned storage shelves in the cockpit and removable pouches behind the seat shells, which can be folded forwards. The front luggage compartment has a volume of 100 litres, enough to accommodate the weekend baggage of the car's two occupants.

Though not yet a production car, the control panels on the Le Mans haven't been ignored. All the main sources of information are directly in front of the driver, where the instrument cluster is divided into three sections: the rectangular centre section flows in a droplet pattern into the information units at the left and right.

Whereas the revolution counter at the left, although operated digitally, has a classic circular dial, the interior designers have pursued an entirely new path for the right section of the instrument cluster. The large-format digital display uses the TFT technique and can be switched between three modes - analogue, track and MMI - by the driver.

When cruising, and in the analogue mode, the surface becomes a digital speedometer with an analogue display and an additional clock display. For a more racing car ride the driver can use the track mode to display a plan of the circuit. Information obtained by GPS is used to show the next bend and to compute the lap time.

The principal data on the engine's operating condition, for instance oil pressure and temperature, can be obtained in the MMI mode. For road use, this is where the route guidance pictograms supplied by the navigation system in the TFT display are shown.

The system is controlled from the MMI terminal, which is located on the centre console - an operating concept that has already proved convincing in the Audi A8 production car.

The small-diameter sports steering wheel also resembles a racing-car design. Here again the use of leather has been avoided and has been replaced with an entirely new material, without losing the sporty feel of the drive.

The A8 is the top of the range model for Audi, but here Zieten explains, they need to carry on using traditional luxury materials like wood, leather and chrome. "The shape of the A8," explains Jenkins, "is very modern in comparison to its rivals at Mercedes-Benz and BMW." Therefore she thinks that the car needs to use material that the luxury driver is used to, perhaps to counteract this, or not to alienate them. "Inside the A8 you have top quality wood, you have soft and durable leather on the seats, this is what the A8 driver wants," says Jenkins.

"On the other hand the TT, or the Pike Peak (originally show at the Detroit show) can bring in aspects that are new to the automotive area," she adds. Perhaps customers for these vehicles demand new concepts interior wise including colour and trim. "This is another direction," adds Zieten. In a sports car there are more possibilities to introduce a modern interpretation. "But here the customer will probably want leather seats in it in the end," adds Jenkins sarcastically, pointing at the Le Mans. "It has to do with the perception of luxury," she adds.

Show cars are always fast to make, says Jenkins. In fact it took only eleven months between the initial design sketches to what was display at Frankfurt. Finding the fabrics seemed to be the most exciting part for the team.

"It's not like we can just find a material and put it into the show car," she adds. For this project the team were encouraged to be very experimental and to get inspiration visited many non-automotive events such as fashion shows and the Milan Furniture Show in particular, where many trends can be spotted.

The team then gathers all these new materials and manipulates them for inspiration for show cars. Then it is time to convince the managerial people. Show cars are normally under the decision of the chairman, they have little to do with the marketing people. "It isn't often that they would say: 'no problem'. We have to convince them of our ideas," says Jenkins. The marketing team is not yet involved at this stage, they explain. There is around five years developing time following such introductions.

It seems that in this case the Le Mans project was a big success for the Audi design team. Jenkins explains that the general mood was incredible the night the concept car was launched. "It was as if he (Dr Martin Winterkorn, chairman of the board of management at Audi AG) was on cloud nine," she adds. He even chose to drive the car himself around the racecourse, which may have proved a little, risky as it had been driven only twice before the show. This is what sets Audi a little aside from the others in that its show cars are real cars, not just shiny and painted clay models.

There are around 150 people working at Audi design studio with around 40 in interior design and just ten people in colour and trim. Normally a group is put together for show cars, a brief is put forward and the designers compete for the winning concept. Jenkins says in design you have two types of characters, one who likes to participate in the design of production cars, and the other who is destined to make show cars. "One of us has to get involved in show cars," adds Jenkins.

The interior and colour and trim group answers directly to Gerhard Pfefferle, head of design at Audi AG. He in turn passes things by Walter de'Silva, the man behind the Audi AG group brand that includes Lamborghini, Audi and Seat. Finally all information goes to Winterkorn and then to main chief Dr. Bernd Piechestrieder. "First we have to show our concepts or proposals to Mr Pfefferle and Mr de'Silva to convince them of the idea to use say different material. Then we prepare the presentation for Dr Winterkorn," says Zieten. "He takes something like 5 seconds to let us know if the colour for instance is right or wrong." But he is the boss after all.

Murat Gunak, new head of the Volkswagen group and de'Silva discuss matters to do with the general direction of the two brand groups that make VAG. "But on our level," explains Zieten, "we don't have any idea as to what goes on at VW. This is on purpose as it is important for us not to get disrupted. We don't want to steel ideas or to be compared." Instead he explains Audi's competition, or benchmark, is BMW and Mercedes Benz. "We are always looking for new material, for new ideas and for suppliers which can develop for us new concepts and materials. Everyone in Europe is searching for this new supplier and so it is treated like a secret," he adds.

"In a sense," adds Jenkins, "the wall between VW and Audi could said to be higher than the one between us and BMW." Audi is the sportier and perhaps the more adventurous VW brand and as a result it has to and is encouraged to push itself to the limit and this includes in terms of colour and trim. "We are the innovative ones," she adds. There is much movement within the VW group and naturally they take some of themselves with them. Jenkins points to the new R Concept at the Volkswagen stand at Frankfurt and says that you can see that there was and Audi designer working on this show car. "For us it is obvious," she adds.
