Design
Unmistakable face by day and night
The passion expressed through the elaborate design of the lights is another typical Audi trait. The R8 already acquires an unmistakable frontal aspect through the standard bi-xenon headlights and daytime running lights comprising twelve light-emitting diodes – day and night alike. Nor is anyone likely to overlook this Audi sports car from behind: for the very first time, LED tail lights with a three-dimensional effect have successfully been used.
But the absolute highlight will be the all-LED headlights, available for the
Audi R8 as an option from the end of 2007, and making their first ever appearance worldwide on a production car. With their lenses and reflectors, these innovative light sources not only look progressive; they also have an enormous functional advantage: with its colour temperature of 6,000 Kelvin, LED light resembles daylight much more closely than xenon or even halogen light. Drivers will consequently suffer much less fatigue when driving at night.
The interior offers a luxurious standard of motor racing atmosphere. Its design is as sporty and exclusive as the exterior: the characteristic element here is the monoposto – an expansive arc running around the steering wheel and instruments, connecting the driver to the car. The interior consequently picks up on the dynamism of the R8 and gives it tactile expression in a form that is accessible the moment you climb in.
Exceptionally spacious
For a sports car, the exceptional everyday suitability of the R8 is highlighted by the large amount of space, due in no small measure to the generous wheelbase of 2.65 metres. Whatever the build of the driver and passenger, they will always be able to find their perfect seated position. The view is also very good for a mid-engine vehicle. Narrow A-posts optimise the field of view to the front and sides.
The luggage compartment is an important aspect of everyday suitability: 100 litres fit beneath the front lid, and there is room for bags with a total volume of a further 90 litres behind the seats. And even passionate golfers need not forgo their sport when driving the R8: two full-size golf bags can be stowed behind the seats.
The impression of quality in the interior is striking: even in the basic specification, the surfaces of the driving area and door trims are meticulously trimmed, with neatly finished decorative seams. And the scope for customisation is as diverse as the preferences of the R8’s future owners could conceivably be: piano finish, carbon fibre and leathers in an extremely wide range of colours are just some of the options.
Light but highly rigid body
The body of a sports car needs to be particularly light and rigid: low weight permits superior road performance, and rigidity is the crucial starting point for an agile driving feel allied to high precision. The Audi Space Frame body, made from aluminium, provides the ideal basis for this. Audi has more expertise than any other manufacturer worldwide in the designing and production of cars based on aluminium technology, and has channelled its accumulated know-how into the R8.
The entire bodyshell of the R8 weighs just 210 kilograms, the pinnacle of achievement among sports cars in terms of lightweight design quality. It comprises extruded sections, aluminium panels and highly complex cast nodes, joined together by 99 metres of weld seams, 782 punch rivets and 308 self-tapping screws.
Superlative precision in the production shop
This structure is created largely by hand at the R8 production shop in Neckarsulm, but with precision measuring and machining methods keeping a watchful eye over the whole business: a laser measuring system checks 220 points on each body to within one-tenth of a millimetre, and a special computer tomograph can investigate the absolute quality of every join with micron precision. A central processing plant cuts and drills all 52 connecting points on the running gear and steering in a single pass. This assures maximum precision in the axle geometry.
The aerodynamics experts at Audi have done their work so thoroughly on the R8 that, as an added benefit of its elegant shape, the body actually generates downforce – unlike many other sports cars. This promotes directional stability at high speeds. It is achieved by means of the extending rear spoiler, but above all thanks to the fully clad diffuser underbody.
