Audi R8 (car of road)
See also: Audi R8 (homonymy)
The Audi R8 is very first the half-compartment WP (2 places) of the German mark to the four rings: Audi. This one competes thus for the first time since its creation in 1910 with the famous brands on the matter, namely Porsche (911), Ferrari or Aston Martin.
Audi R8 draws its name from the victorious car to the 24 hours of Mans, which had the same name (see: Audi R8 (racing racing car)). Show-because Avus of the Auto show of Frankfurt of 1991, the prototype Audi Quattro Spyder or the Concept-because Audi Mans Quattro was the inspirers of current R8.
Audi R8 was officially presented to the Mondial of the car of Paris of 2006 and is present in the concessions Audi since April 2007. It is produced with Neckarsulm (Bade-Wurtemberg) in Germany. Audi wishes to sell a hundred units in France in 2007, knowing that the basic price is of 106.900 € in version manual box 6 reports/ratios and of 114.350 € for the robotized version.
Performances
With its engine V8 (4 valves per cylinder) FSI of 4,2 L in central position postpones borrowed from the truck Audi RS4, Audi R8 passes from 0 to 100 km/h in less than 5 seconds. This engine can reach a mode of 8.500 tr/min, deploys of 100 ch au liter and a top speed of more than 300 km/h, higher than its competitor the Aston Martin V8 Vantage. Its couple reaches to the maximum 430 Nm (that is to say 43,8 mkg) with 4.500 tr/min. The transmission Quattro of last generation installed on Audi R8 privileges the couple on the rear wheel-axle unit with 56%.
Audi R8, with 4.163 cm ³ of Rolled, deploys 309 KW is 420 ch with 7.800 tr/min and thus outclasses its main competitors. This performance is possible thanks to the Châssis any aluminum thus conferring to him only 1.560 kg, but also thanks to the very detailed attention of Audi to the Aérodynamisme. Indeed, Audi R8 proposes a Cx of 0,345 and a negative Portance. The weight ratio/power is then of 3,7 kg/ch .
The braking of Audi R8, via four ventilated discs, equipped each of 8 pistons with before and with 4 with the back, is very corrosive. With low as at high-speed, Audi R8 benefits from a remarkable stability thanks to the suspensions with double triangulation but also thanks to the option (invoiced 2.100 €) Audi Magnetic Ride which makes it possible to adapt the force of damping uninterrupted.
This technology uses an oil containing of fine metal particles of a few microns (called fluid magneto-rheological ), which under the effect of an electric field creates by a Bobine placed in the body of the Piston, varies the position of the particles and modifies of this fact the Viscosité of oil, thus generating the strengthening of the suspensions.
Design
Optics of Audi R8, pointing out the eyes of a falcon, is underlined by a chain of 12 LED (electroluminescent diode), one of new technologies as regards lighting (much more effective than xenon), for a lighting of day. The Calandre of Audi R8 takes again the design Single Frame which equips all Audi recent. However the four rings of the mark are this time on the cap and not on the grill.
In addition, the color of the body of Audi R8 is not inevitably uniform thanks to the presence of Side Blade (on the sides) from which the tone can be different from the remainder of the vehicle. In certain cases, this possibility with a overcost.
Audi R8 is sporting and sober at the same time: the typical neat interior of the German mark, the four exits of exhaust and the aileron which is raised starting from 100 km/h (and which is closed again in lower part of 80 km/h) are the witnesses. R8 in addition takes again the noncyclic wheel at base punt appeared on the Audi RS4, and which equips from now on the unit with the ranges S and RS.
Habitability - Comfort
Dimensioned habitability and comfort, Audi R8 is equipped with many technologies as of the version of series like: the projectors xenon, automatic air-conditioning, the car radio CD, the system idSAT (immobilization and localization by satellite) and saddlery leather (seats sport). The integral leather preparing is as for him in option.
Audi proposes thus all the same a chain of options like: the Audi Hill Hold Assist (assistant of hill start), the assistance system with the carpark before and back (with or without camera of retreat), the automatic lighting of the headlights, the speed regulator or the system audio Bang & Olufsen .
However, the volume granted to the loading is rather restricted: 100 DM 3 in the part before Audi R8 and 90 DM 3 behind the seats.
Audi R8 is equipped with very many electronic assistances : ABS with amplifier and distributer of braking, electronic blocking of differential, ESP désactivable on two levels, Antipatinage…
Targa version
Audi R8 version Targa ( Roadster or Spider , commercial name not being yet official), will be in fact Audi R8 under the convertible variation . It will be marketed only in spring 2009, but will be surely presented a little front in the form of concept-because. Its price could reach the 130.000 €.
Version RS8
The version Audi RS8 differs aesthetically only little with Audi R8. Side Blades are more open in order to engulf there a maximum of air for the cooling of the engine. The back aileron is slightly more imposing to maximize the support on the ground with high-speeds.
It is only under the cap that the principal difference is: the RS8 would be been driven by an engine V10 developing 490 with 500 ch against " seulement" 420 of Audi R8. One also speaks about a block V12 TDi 6,0 (diesel) biturbo of 500 ch for 1.000 Nm of couple. On the other hand the engineers have difficulties in insert this engine in the car. The brake was slightly modified to grant more the corrosive one to him. The launch date of this model is unforeseen because the car test of the RS8 has took fire at the time one day of test on circuit.
