Sovereign
.
Audi represent the most powerful model. The concept of this super-model of a series A' was placed quattro GmbH and it was developed by concern Audi AG. Engine V8 of automobile Audi R develops 331 kV (450 ls) and possesses the power of sport automobile. C by the aid of the innovation system of dynamic control of the trip and by the eighth of piston brake system are opened the new horizons in the dynamics of driving. Exclusive athlete is represented deliberately with restraint on his formulation.
.
Audi R personify the unique packet of high technologies. In the sphere of highly effective transportation means its high power, constant all-wheel drive, highly effective brake system and innovativnaya system of the control of ride establish the new horizons.
.
In comparison with other high(ly)-functional sport automobiles to drivers and for passengers it is not necessary to go to the concessions: automobile Audi R is produced both in the body sedan and in body Avant(universal).
.
Design Audi R - this explicit assertion. The unequivocal acknowledgement of high power is, first of all distinctive differentiation, and the secondly - its enormous potential.
.
Low- omitted revetment of radiator with three intakes of air in the form of rhomb, 18- TI or 19- TI the one inch disks from the light metal, the decent lateral threshold, in a new way designed rear mud guard and cover plate on the boot-lid of sedan emphasize dynamics Audi R
.
Power of motor, which emanates from only
.
V- descriptive engine with 4.2 liters of working volume develops in Audi RS 6 with 5700 to 6400 r/min a constant power in 331 kV (450 ps). Uncommon is the fact that its maximum torque into 560 N*m to be located in the extremely broad band from 1950 to 5600 r/min.
.
Large part of the enormous gain 190 it occurs due to two turbochargers, whose effectiveness even more is improved due to two coolers of air, developed for decreasing the loss of pressurees. Each cylinder block includes one supercharger. Power unit Audi RS 6 consists of the aluminum cylinder block, five valves to each cylinder, three of which are entrance, and also yoke on sharikopodshipni e7f of kakh.
.
For an increase in the power entrance and release valves in the head of cylinder block altered in a new way, and also developed new technologies with respect to the air conduits of the suction and pushing out parts of biturbodvigatelya. For the optimum heat removal in the region of the combustion chambers and valves the water jacket of engine was tselenapravlenno optimized.
.
For the effectiveness of power unit also serves adapted engine control. Motronik ME 7.1.1 from Bosch governs boost, detonation and discharge temperature. Specially for using in Audi RS 6 its possibility they enlarged to the turbo- functionality.
.
Double-flow, optimirovannyy against the back pressure exhaust mechanism was completely re-developed. It consists of special average and final mufflers, union pipes of large diameter, and also preliminary and basic catalysts. With the aid of the directed tuning in entire range of frequencies of the engine revolutions the sport sounding of motor is synthesized. Audi R Satisfies standards EU3.
.
For an improvement in the weight distribution of aggregates in the automobile storage battery is located in the department for the spare wheel. Air filter with two filtering elements is fixed on the engine. Its housing, made from carbon fibers and connecting material, together with the carbonic plate enters into the cylinder block cover of power unit V8.
.
Power of engine
.
The thrust of the constant drive quattro determines the high torque V8 biturbo. Audi RS 6 is accelerated to 100 km/h 4.7 s, prior to 200 km/h for 17.6. The maximum speed in 250 km/h is limited to electronics.
.
Tiptronik, disposed to sport
.
Specially for R the developed by 5- TI stepped gearbox, analogous is established on 6- TI of the liter 12 drum Audi A8 6.0, it manages the developed torques easily. The adapted program of tiptronika will recognize the style selected by driver and according to it it displaces the points of the moment of switching.
.
Characteristic, it is emphasized sport automobile, develop tiptronik in RS 6 with the aid of the dynamic sport program: regime S turns off transfers in the higher revolutions and serves for the later switching to the highest transfer and for the earlier switching to the low gear. In this regime the points of gearshift also are set to the style of the driving of automobile.
.
One special feature is manifested during the sport motion along the curve. In this case tiptronik in accordance with the angular acceleration selects the subprogram, which even more late changes gears. Thus, transfers are switched more lately. In this case are excluded undesirable switchings during the progress of curve, and also interruption of pulling power.
.
Certainly, driver Audi R can govern tiptronikom also by hand. For this is used the switch in the middle part or two handles along the sides of steering wheel. These handles are so fixed on the steering wheel, which are conveniently switched them with any position of steering wheel. Right switch serves for the switching to the more high gear, leftist - for the switching to the more low gear. It is sufficient light pressure for the switching.
.
If driver actively is included in tiptronik, then he by his selection of transfer in 10 s. includes entire program of control of motion. Control of gearbox is checked against the object of gearshift from the considerations of safety.
.
Highly effective brake system
.
According to the high technical characteristics of automobile quattro concern developed completely new brake system. Retarding discs are located on the front and rear axles of automobile.
.
For guaranteeing the on- possibility of lighter weight and hence smaller not spring-loaded mass serves brake fixed clamp from AL f47 yuminiya. Connection with the aired from within cast rings frictions are fastened the 14th with radial steel pins. This construction serves for the thermal expansion of connection.
.
Floating support increases stability with the low weight, especially with the extreme loads and at high temperatures of operation.
.
Ventilation retarding discs have a diameter of 365 mm on the front axle, and on the rear axle - 335 mm. from the front slow down 8-mi- piston brakes with the hard disk, from behind - by odnoporshnevoy brake assembly with the floating clamp in conjunction with the hand brake.
.
Parameters of system ABS and distribution of electrons of brake force change in the dependence with the data of hydraulic system. The algorithms of the system of anti-blocking established on the sport standards unequivocally are aimed at the very short braking distances and the optimum checking of braking.
.
Undercarriage
.
By place for the successfully calculated brake assemblies are 8.5 J * 18- TI one inch alyuminevye cast disks the 9th by cuts with the casings of the size of 255/40 R 18. At will Audi R it is completed by 9 J * 19- TI by the one inch aluminum disks of five-beam design with the casings 255/35 R 19. Winter disks have a size of 7.5 J * 18 and are completed by casings with the sizes of 225/45 R 18 m+.s for the optimum pulling power and the controllability of automobile.
.
Audi R are in series completed by control system of pressure in the tires. This system follows the pressure of four wheels during the trip both in the usual and in the winter casings. Deviations from the assumed pressure immediately are noted on the control display.
.
Rotary support and lever of the independent suspension of the wheel of 4-X- lever front axle are prepared from aluminum for decreasing the not spring-loaded mass. Spring shock absorbers and elastokinematika are coordinated with different weight of axis and axis for the purpose of the sport controllability of automobile modified by geometry. The massive stabilizer of lateral stability and rack steering gear make a contribution to clearly expressed sport control of automobile. From behind is located bridge with the independent suspension on the dual transverse levers in the complete set with the stabilizer.
.
Dynamic the control of control: the dynamics of driving in new measurement
.
V Audi R for the first time is used the concept of the dynamic of the control of control DRC. this system of the extinction of longitudinal and lateral oscillations it consists of special system, which resists the fluctuations of transportation means without the use of electronics. With the turnings and the passage the curved regime of the extinction of fluctuations changes so that the displacement of automobile along the longitudinal and transverse axes considerably they decrease.
.
Mufflers from each side of automobile are connected with the located diagonally located opposite them extinguishers with the aid of two separate oil-lines with the central valve. Valves DRC, which are located in the region of rear axle, by means of those being being located inside the pistons with the rear gas chamber, ensure the necessary volume for the extinction of fluctuations.
.
With the turnings and the passage the curved flow of oil is fixed through the central valve between the cross-shaped established shock absorbers and, thus, it ensures additional damping.
.
Recognition of fluctuations with the one-sided sagging changes so that the transverse and longitudinal vibrations almost completely are removed. Thus, extinction system of fluctuations serves so that Audi R very stably would be passed the bent sections.
.
With the equilateral sagging usual damping is active. So is ensured unusually the high for the sport automobile smoothness of rolling.
.
Kuzov with DRC- mechanism serves for the the high of urovn of 192 4 conveniences, precise drivings and neutral povorachivayemosti, even with the high angular velocity. Audi R Thus are opened the new horizons for the development of transportation means.
.
Here also introduces contribution serially produced built-in stabilizing program (ESP). ESP new generation is calculated for the sport ride. Even with the very dynamic method of driving the program of pribega fda yet to the limitations at the worst and to the very short period.
.
Options ABS with EBV (the distribution of electrons of braking effort), EDS (electronic blocking of differential), ASR (control of the slippage of front wheels), and also control of the distribution of torque, work in the totality and makes a contribution to the general safety of automobile. Control of the moment of conducting MSR is opened or it shuts chokes and transfers braking effort in accordance with the requirements of this situation. Information is given by official importer Audi AG in the Ukraine - "automobile group" OF VIPOS ". With the use of materials the reference is required.
