Audi ultra in the Audi R8 Coupé.

Every gram less extends the lead.

A straightforward principle applies for Audi ultra: the lighter the body, the better the weight/power ratio and thus the vehicle performance. An innovative multi-material design fills this theoretical principle with life. We are concentrating on the overall concept rather than on individual components or special materials. And it is this flexible approach that gives us the freedom to build a sports car that offers a unique driving experience.
Audi Space Frame (ASF®)
Audi ultra is the innovative lightweight technology from Audi. One convincing example of this technology is the Audi Space Frame (ASF), a high-strength aluminium frame structure. The body of the Audi R8 Coupé, for example, is made up of different components. 69 % are extruded profiles, 8 % vacuum cast nodes and 23 % light aluminium panels. This distribution of semi-finished goods contributes to the high-quality lightweight design of the R8 body – the ratio of weight to size and rigidity – being the very embodiment of “Vorsprung durch Technik”. The lightweight material aluminium offers greater freedom of design for cast parts and extruded sections than steel and the components made from it are noted for their high rigidity.

In addition to the lightweight design related to specific material savings without lowering the standard of comfort and vehicle safety, the Audi R8 also uses especially light carbon fibre reinforced plastic (CRP) in addition to the main material aluminium. Seven strands of carbon fibre put together are only as thick as one human hair. The finished CRP component is more stable than traditional materials – and lighter. What this means for you is a high degree of safety, greater performance and improved handling.

Weight reduction
Since the term Audi ultra is used to describe the lightweight engineering throughout the vehicle, it not only includes the body and its materials, it also takes all other components and systems into consideration. Without compromising the high quality and production standards typical for Audi, of course. The brakes deserve particular attention. The standard brake system in the Audi R8 has so-called wave discs. Their cast friction rings have a wave-shaped outer contour and are connected to the brake disc chambers by means of aluminium pins. This reduces the total unsprung and rotating masses by around 2 kg, leading to improved driving dynamics and better roll characteristics.

Vehicle energy consumption depends on numerous factors. No less than 11 % are influenced by the aerodynamics. For this reason, Audi has had one of the most modern wind tunnel centres in the world for years, and works constantly on optimising every model in terms of drag. A turbine with a diameter of 4 metres and drive power of 2.6 megawatt blows air through the wind tunnel at up to 300 km/h.

The smoothed shapes of the Audi R8 also had to undergo numerous tests. Before the vehicle was ready for series production, it was analysed and improved for more than 1,000 hours in the wind tunnel. On the one hand in order to achieve low drag for a high final speed and moderate consumption values, on the other to produce the downforce necessary for good handling and improved driving stability at high speeds. The front spoiler, the extendable rear spoiler and the fully lined underbody were designed so that contact pressure is increased.

The LED headlights


The new headlight design makes the Audi R8 easily recognisable – by day or night. This is mainly due to the characteristic appearance of the daytime running light strip which surrounds and emphasises the apparently floating dipped beam lens. The 6 LED arrays in the reflector chambers shine together with the spotlight to illuminate the road evenly with the bright, pleasant light colour typical of LED lights. The indicator is integrated in the upper daytime running light as a clearly defined line. In addition, the Audi R8 now has a static turning light which, depending on the specified steering angle, is activated automatically at speeds of up to about 70 km/h or at speeds of up to 40 km/h with the indicator switched on to illuminate the course of the road more brightly.

S tronic®

The S tronic transmission combines the low fuel consumption of a manual transmission with the benefits of an automatic. The control ensures fast and consumption-reducing gear shifting in automatic mode. The very large transmission-ratio spread of the S tronic allows the last gears to be used at very low engine speeds.

Wave brake discs

The standard brake system with its innovative wave discs guarantees even more efficiency. The wave-shaped contour of the friction rings and the disc chambers made of aluminium lead to further weight savings.
