Yo no tendria tan claro q este coche vaya a andar mas q el 335i, ademas de q seguro va a valer por lo menos un milloncete mas. No es lo mismo compresor volumetrico q biturbo, y en recuperaciones me juego el cuello a q el bmw tendra mejores registros, ademas d q no creo q ahora el s4 vaya a ser mejor q el s5 (pretendidamente mas deportivo y q en las pruebas realizadas a andado muy a la par con el 335i).
P.D: Nunca he sido de los q tachan a otras marcas de copiones, pero me da la sensación de q Audi ha intentado hacer un motor a lo 335i. Eso de 3 litros de cubicaje y compresor.... no se lo habia visto nunca.

Audi tiene importantes nubarrones sobre su cabeza.
Porsche dentro de unos meses tomará el control del grupo VAG y lo primero que hará será tomar las siguientes decisiones:
- Apropiarse del 3.0 tdi para el Cayenne, concretamente 20.000 udes/año.
- Impedir nuevas motorizaciones en el R8, por ejemplo, el V10. Aunque no tendrá tiempo material para paralizar el R8 V10.
- Mandar a la caverna al futuro R4:
Audi R4 - un render e il punto sulla situazione
- Al A7 se salvará porque está totalmente terminado, pero es competencia directa del Porsche Panamera.
Porsche Panamera: il primo teaser ufficiale
Se avecina guerra total y lo más seguro es que la sardinilla se coma al tiburón, 16 veces mayor que Porsche.
La idea de Porsche es acabar con los Audis Prestacionales en segmentos que les quiten ventas a ellos.
NOTICIA DE AGENCIA DE PRENSA:
NOTICIA:
Era algo que aunque no se confirmase, todo el mundo sabía. No hace falta imaginarse que esto iba a suceder tarde o temprano. Casi todo el mundo se imaginaba que Porsche buscaba entrar en el accionariado de Volkswagen para quedarse con la guinda del pastel que es Audi, y vender el resto de marcas del Grupo VAG.
Wendelin Wiedeking, presidente de la marca deportiva con sede en Stuttgart, siempre ha negado que sea ésta su intención, pero nunca logró despejar tales temores. Las informaciones que situaban a Porsche presionando a Audi para que renunciase a su deportivo R8 y se olvidase del futuro R4, han sentado como latigazos. Una muestra de la poca confianza que se vive en el Grupo Volkswagen es la propuesta presentada el viernes en el consejo de vigilancia de VW por el sindicato IG_Metall, que blinda y deja atada Audi al consorcio.
La propuesta salió adelante gracias a la abstención en el voto de Ferdinand Piëch, presidente de este consejo, perteneciente a una de las dos familias propietarias de Porsche y ex-presidente de Volkswagen. Pero desde la adquisición el día 16 de septiembre de un 4,9% adicional de acciones, las tornas pueden variar, ya que poseen el 35% de las acciones y la mayoría absoluta.
Wolfgang Porsche, cabeza visible de la marca de su apellido, tiene toda la pinta de querer aprovecharse de la situación y prescindir de su primo Ferdinand. Haciendo esto, tendría el control absoluto del consejo, podría quedarse con Audi (seguramente su prioridad) y desechar el resto de marcas. Guerra de familia que no va a terminar nada bien, seguro

Dices que el a7 está totalmente terminado??, supongo que pronto lo veremos, ví alguna foto espia y tenía muy buena pinta.
Eso de competencia con el panamera... el dinero lo dirá pero creo que distaran mucho los precios de uno con los del otro

Las últimas noticias hablan que el A7 no se basará en el A6 sino que será la versión coupe de 4 plazas del A8, es decir que llevará la plataforma modular del A8.
Eso significa aumento de precio.
El A7 se presenta en Junio de 2009, quedan 9 meses, es decir, que está terminado y estarán haciendo el ensamblaje de la cadena para unidades de preserie y ajustes.
Como dato, un diseño de un coche se congela (queda totalmente definido) entre 2-3 años antes de que salga. Por ejemplo, BMW tiene ya congelados los diseños del Z4, X3, Serie 5, Serie 5 coupe y posiblemente este en estos momentos discutiendo sobre el diseño final del Futuro SErie 3.
Las marcas Premium ya no ganan lo que deberían y buscan productos más caros y exclusivos.
Por ejemplo, desaparece el futuro CLK y ahora se llamará CLASE E COUPE, con el consiguiente aumento de precio ya que llevará la plataforma del futuro Clase E en vez la del Clase C.

clase E coupé... que raro, perderan muchisimo en prestaciones y no pondrán competir ni con el a5 ni con el e92...
Y bmw sacará un serie 5 coupé?? me imagino que será un 5 puertas no un 3 no??
El a7 será algo parecido al mercedes CL me imagino, este es igual que el S pero 3p... que raro todo, promete el año 2009 ;-)

Lo más importante del S4 es en este caso su motor.
/S4%20Sedan%20(B8)/Technical/030.jpg)
Pensaba que el par sería superior al del S5 pero tienen el mismo, eso sí lo mantiene más constante entre 2900-5300 rpm.
También a destacar la caja de cambios S Tronic de 7 velocidades, diferencial deportivo como suspensiones pilotadas con regulación de la dureza a través de electroválvulas en funcion de los datos obtenidos por 14 sensores.
Datos de recuperaciones ofrecen este (supongo que será en sexta) 80-120 Km/h en 4.4
Un saludo.

The New Audi S4/S4 Avant
Sep 22, 2008
[FONT=Verdana, Arial, Helvetica, sans-serif]• Three-liter V6 unit generates 245 kW (333 hp)[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]• Acceleration from 0 to 100 km/h in 5.1 seconds[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]• Average fuel consumption of just 9.7 liters[/FONT]
Ingolstadt – Audi is introducing its new sporty top models in the midsize class – the S4 and the S4 Avant. Their engine, a three-liter V6 with direct fuel injection and mechanical turbocharging, delivers a powerful 245 kW (333 hp). It accelerates the S4 to 100 km/h (62.14 mph) in just 5.1 seconds, but on average only uses 9.7 liters of fuel per 100 km (24.25 US mpg). The quattro permanent all-wheel drive system transfers its power to the road in style, which is then converted by the sport suspension into dynamic handling. Upon request, Audi can equip the new S4 and S4 Avant with innovative technologies that further increase their lead over the competition. The seven-speed S tronic changes gears with lightning speed, and the new sport differential distributes the torque as needed between the rear wheels. The new Audi S4 will be unveiled to the public for the first time at the Paris Auto Show from October 2 to 19.
The heart of the new S4 and S4 Avant is a completely redesigned engine. The 3.0 TFSI, the newest member of the Audi V-engine family, is an outstanding example of how the brand with the four rings blends performance and efficiency. The V6 generates its power from a displacement of 2,995 cc, is equipped with a supercharger, and delivers 245 kW (333 hp). The sedan sprints to100 km/h (62.14 mph) in just 5.1 seconds, and the Avant in 5.2 seconds: they both have an electronically governed top speed of 250 km/h (155.34 mph).
The "T" in the 3.0's TFSI nomenclature no longer merely stands for "turbo", but rather for the concept of supercharging in general – extensive testing on the big V6 has proven the superiority of mechanical charging. In conjunction with direct injection it is far superior to twin turbochargers, both in terms of packaging and of starting performance and responsiveness.
The compressor is so compact that it easily fits inside the 90-degree V of the cylinder banks, in place of the intake manifold. Two four-vane rotary pistons counter-rotate inside the turbocharger at up to 23,000 rpm. Two charge-air coolers are integrated into the housing and are connected to a separate coolant circuit. An impressive array of measures keeps the noise generated by the compressor to a minimum.
The engine-driven belt that powers the mechanical charger provides full thrust right from idling speed. The 3.0 TFSI delivers its maximum 440 Nm (324.53 lb-ft) at 2,500 rpm and maintains this constantly until 4,850 rpm. In fourth gear, the vehicle accelerates from 80 to 120 km/h (49.71 to 74.56 mph) in just 4.4 seconds. Thanks to the extremely short gas paths, the sonorous, supercharged V6 responds spontaneously to the throttle, even more so than a naturally aspirated engine of the same displacement.
Furthermore, the new 3.0 TFSI achieves exemplary fuel efficiency. On average, the sedan uses 9.7 liters of fuel per 100 km (24.25 US mpg), and the Avant 9.9 liters per 100 km (23.76 US mpg) – an improvement of 3.4 liters (26 percent) compared with its predecessor. The Audi technology of gasoline direct injection was what made this great efficiency possible in the first place. Unlike conventional concepts, it allows the compressor to be located behind the throttle valve. In view of the low density of the intake air at loads below supercharging level and when coasting, its rotors are free-running and the amount of power required to drive them is low.
Dynamism and efficiency: The new seven-speed S tronic
The V6 power in the new S4 and S4 Avant flows into a six-speed transmission, fitted as standard, which shifts quickly and precisely. As an option, Audi offers a state-of-the-art dual-clutch transmission – the seven-speed S tronic is extremely dynamic and highly efficient. The driver has the option of driving in fully automatic mode or selecting the gears with paddles on the steering wheel or directly with the shift lever – all of which provide impressively quick gearshifts. The gearshift feel is dynamic, comfortable and very precise – typically Audi.
The seven-speed S tronic consists of two separate transmissions and uses two multidisk clutches that control the various gears. The large K1 clutch guides the power via a solid shaft to the pinions for gears 1, 3, 5 and 7. A hollow shaft rotates around the solid shaft; it is connected to the compact K2 clutch, which is integrated within its larger counterpart and controls the pinions for gears 2, 4, 6 and reverse gear.
Both transmission structures are continuously active, but only one is powered at a time by the engine. For example, when the driver accelerates in third gear, the fourth gear is already engaged in the second transmission structure. The shifting process takes place as the clutch changes – K1 opens and K2 closes with lightning speed. This process takes only a few hundredths of a second and is completed without interrupting traction. It is so comfortable and smooth that the driver hardly notices it.
The seven-speed S tronic is designed for maximum efficiency. It operates with very high efficiency and its intelligent control system maximizes fuel economy in automatic mode. With its wide gear ratio spread of 8.0:1 the seven-speed S tronic easily exploits the tremendous power and superior torque of the 3.0 TFSI.
The quattro permanent all-wheel drive system transfers power to the road with supreme ease. Under regular driving conditions, it sends 40 percent of its torque to the front wheels and 60 percent to the rear wheels – a slightly rear-biased, sporty characteristic. Where necessary, it can vary distribution within fractions of a second.
The quattro drive system ensures safe self-steering characteristics, high stability and excellent traction in comparison with rear-wheel-drive competitors.
Customized torque distribution: The sport differential with Audi drive select
The new, active sport differential ideally complements the quattro drive system and lends it even greater fascination. When the steering wheel is turned or the car accelerated in a corner, power is redirected in a controlled manner to the outer rear wheel, literally pushing the vehicle through the corner. The system intervenes to counter any signs of understeer or oversteer. For the driver, this means reduced effort at the steering wheel and even higher lateral acceleration.
The active sport differential is a new type of rear-axle differential. A superposition gear was added to both the left and right sides of the classic differential; it rotates ten percent faster than the wheel's drive shaft.
Both components can be connected through a multidisk clutch, which runs in an oil bath, and is operated by an electro-hydraulic actuator. In most driving situations, the clutch can divert almost the complete input torque to one wheel in this way.
Controlled by an array of sensors and a high-speed computer, the active sport differential needs less than 100 milliseconds to redirect power. Drivers can adapt their manner of driving, along with characteristics for the load changes, to three performance maps. Unlike competitors' systems, the Audi sport differential is just as effective when the engine is driving the wheels as it is on the overrun or when the car is coasting freely.
The new Audi S4 and S4 Avant are well-trained athletes. Their five-link front axle and the self-tracking trapezoidal-link rear axle are of a highly sophisticated design; both axles are made almost entirely of aluminum and are therefore very lightweight. The low-mounted steering gear transmits the steering forces to the wheels without any lag time and gives the driver a precise and sensitive road feel.
The spontaneity of Audi's new midsize athletes is fascinating, and they possess the precise reactions of a thoroughbred sports car. In these transmissions, the differential is positioned in front of the clutch, which made it possible to move the engine 154 mm (6.06 in) forwards compared with the predecessor model. This unusual layout perfectly evens out the axle loads, and also affords the long wheelbase of 2,811 mm (9.22 ft) exceptional stability.
The chassis of both new S models received stiffer axle bearings, and the sporty tuning with stiff shock absorbers puts the chassis 20 mm (0.79 in) closer to the road. Huge high-performance and fade-resistant brakes sit behind the 18-inch and optional 19-inch cast aluminum wheels. The black-painted brake calipers – at the front with the S4 logo – grip the ventilated disks with newly developed brake pads.
Audi drive select: The driving dynamics system
The Audi drive select driving dynamics system is a further high-end technology featured on the new S4 and S4 Avant. It accesses the throttle response characteristics, the shift points for the seven-speed S tronic and supports the speed-dependent servotronic steering. With the press of a button, the driver can decide whether these systems should operate in "comfort," "auto" or "dynamic" mode. If the vehicle is equipped with the MMI operating system, a fourth mode is available which the driver can program according to his own personal tastes and preferences.
Audi drive select can only be ordered in combination with one or more of three additional technologies – the sport differential, adaptive control for the shock absorbers, or dynamic steering, which is an additional high-tech solution. Its zero-play superposition gear, which is driven by an electric motor, varies the ratio by almost 100 percent depending on the speed being driven. In terms of driver safety, the dynamic steering assists the ESP stabilization program by using steering intervention to keep the new S4 and S4 Avant on track when cornering at the handling limits. In many instances, the system renders ESP intervention superfluous.
For the adaptive damper control system, hydraulic gas-pressurized shock absorbers are used which operate by means of additional, electrically actuated valves. They control the flow of hydraulic liquid, thus regulating the shock-absorbing characteristics. A high-performance control unit analyzes the signals it receives from 14 sensors, and calculates the damping power for each individual wheel 1,000 times per second.
An athletic look: The design
Both the Audi S4 and the S4 Avant look athletic and muscular on the road. Some of the most striking modifications to the exterior design are the special aprons, the aluminum-look exterior mirrors, the 18-inch S-design light-alloy wheels, the side rocker panels, the restrained spoiler at the rear and the quadruple exhaust system. The xenon plus headlights with daytime running lights and the rear lights are further distinctive touches.
The interior also underscores the sporty expertise that is the hallmark of both new S models. The sports seats have electric lumbar supports and pull-out thigh supports, and the instrument panel features gray dials with white needles. They also bear the S4 emblems, as do the multifunction sport steering wheel and the key. The interior is in black, with brushed aluminum inlays. Carbon and birch wood inlays are also available, as are stainless steel mesh inlays.
Optional assistance systems provide the driver with even greater control on the road. The adaptive cruise control (ACC) regulates the distance to the vehicle in front, and braking guard issues warnings regarding possible rear-end collisions. The Audi side assist makes changing lanes safer; the Audi parking system advanced makes backing into a parking space easier.
With regard to multimedia, Audi offers an attractive technology package. The communications and entertainment technologies portfolio includes the competition-beating MMI operating system, various types of radio and sound systems all the way up to the high-end solution from Bang & Olufsen, two navigation systems, an iPod interface, and a highly convenient Bluetooth car phone.
Luxurious features such as the three-zone deluxe automatic air conditioning and the dynamic cornering light system known as adaptive light round out the optional equipment.
Audi will begin delivery of its new S models in March 2009.

Customized torque distribution: The sport differential with Audi drive select
The new, active sport differential ideally complements the quattro drive system and lends it even greater fascination. When the steering wheel is turned or the car accelerated in a corner, power is redirected in a controlled manner to the outer rear wheel, literally pushing the vehicle through the corner. The system intervenes to counter any signs of understeer or oversteer. For the driver, this means reduced effort at the steering wheel and even higher lateral acceleration.
The active sport differential is a new type of rear-axle differential. A superposition gear was added to both the left and right sides of the classic differential; it rotates ten percent faster than the wheel's drive shaft.
Both components can be connected through a multidisk clutch, which runs in an oil bath, and is operated by an electro-hydraulic actuator. In most driving situations, the clutch can divert almost the complete input torque to one wheel in this way.
Controlled by an array of sensors and a high-speed computer, the active sport differential needs less than 100 milliseconds to redirect power. Drivers can adapt their manner of driving, along with characteristics for the load changes, to three performance maps. Unlike competitors' systems, the Audi sport differential is just as effective when the engine is driving the wheels as it is on the overrun or when the car is coasting freely.
The new Audi S4 and S4 Avant are well-trained athletes. Their five-link front axle and the self-tracking trapezoidal-link rear axle are of a highly sophisticated design; both axles are made almost entirely of aluminum and are therefore very lightweight. The low-mounted steering gear transmits the steering forces to the wheels without any lag time and gives the driver a precise and sensitive road feel.
The spontaneity of Audi's new midsize athletes is fascinating, and they possess the precise reactions of a thoroughbred sports car. In these transmissions, the differential is positioned in front of the clutch, which made it possible to move the engine 154 mm (6.06 in) forwards compared with the predecessor model. This unusual layout perfectly evens out the axle loads, and also affords the long wheelbase of 2,811 mm (9.22 ft) exceptional stability.
The chassis of both new S models received stiffer axle bearings, and the sporty tuning with stiff shock absorbers puts the chassis 20 mm (0.79 in) closer to the road. Huge high-performance and fade-resistant brakes sit behind the 18-inch and optional 19-inch cast aluminum wheels. The black-painted brake calipers – at the front with the S4 logo – grip the ventilated disks with newly developed brake pads.
Audi drive select: The driving dynamics system
The Audi drive select driving dynamics system is a further high-end technology featured on the new S4 and S4 Avant. It accesses the throttle response characteristics, the shift points for the seven-speed S tronic and supports the speed-dependent servotronic steering. With the press of a button, the driver can decide whether these systems should operate in "comfort," "auto" or "dynamic" mode. If the vehicle is equipped with the MMI operating system, a fourth mode is available which the driver can program according to his own personal tastes and preferences.
Audi drive select can only be ordered in combination with one or more of three additional technologies – the sport differential, adaptive control for the shock absorbers, or dynamic steering, which is an additional high-tech solution. Its zero-play superposition gear, which is driven by an electric motor, varies the ratio by almost 100 percent depending on the speed being driven. In terms of driver safety, the dynamic steering assists the ESP stabilization program by using steering intervention to keep the new S4 and S4 Avant on track when cornering at the handling limits. In many instances, the system renders ESP intervention superfluous.
For the adaptive damper control system, hydraulic gas-pressurized shock absorbers are used which operate by means of additional, electrically actuated valves. They control the flow of hydraulic liquid, thus regulating the shock-absorbing characteristics. A high-performance control unit analyzes the signals it receives from 14 sensors, and calculates the damping power for each individual wheel 1,000 times per second.
An athletic look: The design
Both the Audi S4 and the S4 Avant look athletic and muscular on the road. Some of the most striking modifications to the exterior design are the special aprons, the aluminum-look exterior mirrors, the 18-inch S-design light-alloy wheels, the side rocker panels, the restrained spoiler at the rear and the quadruple exhaust system. The xenon plus headlights with daytime running lights and the rear lights are further distinctive touches.
The interior also underscores the sporty expertise that is the hallmark of both new S models. The sports seats have electric lumbar supports and pull-out thigh supports, and the instrument panel features gray dials with white needles. They also bear the S4 emblems, as do the multifunction sport steering wheel and the key. The interior is in black, with brushed aluminum inlays. Carbon and birch wood inlays are also available, as are stainless steel mesh inlays.
Optional assistance systems provide the driver with even greater control on the road. The adaptive cruise control (ACC) regulates the distance to the vehicle in front, and braking guard issues warnings regarding possible rear-end collisions. The Audi side assist makes changing lanes safer; the Audi parking system advanced makes backing into a parking space easier.
With regard to multimedia, Audi offers an attractive technology package. The communications and entertainment technologies portfolio includes the competition-beating MMI operating system, various types of radio and sound systems all the way up to the high-end solution from Bang & Olufsen, two navigation systems, an iPod interface, and a highly convenient Bluetooth car phone.
Luxurious features such as the three-zone deluxe automatic air conditioning and the dynamic cornering light system known as adaptive light round out the optional equipment.
Audi will begin delivery of its new S models in March 2009.

The New Audi S4/S4 Avant
Sep 22, 2008
[FONT=Verdana, Arial, Helvetica, sans-serif]• Three-liter V6 unit generates 245 kW (333 hp)[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]• Acceleration from 0 to 100 km/h in 5.1 seconds[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]• Average fuel consumption of just 9.7 liters[/FONT]
Ingolstadt – Audi is introducing its new sporty top models in the midsize class – the S4 and the S4 Avant. Their engine, a three-liter V6 with direct fuel injection and mechanical turbocharging, delivers a powerful 245 kW (333 hp). It accelerates the S4 to 100 km/h (62.14 mph) in just 5.1 seconds, but on average only uses 9.7 liters of fuel per 100 km (24.25 US mpg). The quattro permanent all-wheel drive system transfers its power to the road in style, which is then converted by the sport suspension into dynamic handling. Upon request, Audi can equip the new S4 and S4 Avant with innovative technologies that further increase their lead over the competition. The seven-speed S tronic changes gears with lightning speed, and the new sport differential distributes the torque as needed between the rear wheels. The new Audi S4 will be unveiled to the public for the first time at the Paris Auto Show from October 2 to 19.
The heart of the new S4 and S4 Avant is a completely redesigned engine. The 3.0 TFSI, the newest member of the Audi V-engine family, is an outstanding example of how the brand with the four rings blends performance and efficiency. The V6 generates its power from a displacement of 2,995 cc, is equipped with a supercharger, and delivers 245 kW (333 hp). The sedan sprints to100 km/h (62.14 mph) in just 5.1 seconds, and the Avant in 5.2 seconds: they both have an electronically governed top speed of 250 km/h (155.34 mph).
The "T" in the 3.0's TFSI nomenclature no longer merely stands for "turbo", but rather for the concept of supercharging in general – extensive testing on the big V6 has proven the superiority of mechanical charging. In conjunction with direct injection it is far superior to twin turbochargers, both in terms of packaging and of starting performance and responsiveness.
The compressor is so compact that it easily fits inside the 90-degree V of the cylinder banks, in place of the intake manifold. Two four-vane rotary pistons counter-rotate inside the turbocharger at up to 23,000 rpm. Two charge-air coolers are integrated into the housing and are connected to a separate coolant circuit. An impressive array of measures keeps the noise generated by the compressor to a minimum.
The engine-driven belt that powers the mechanical charger provides full thrust right from idling speed. The 3.0 TFSI delivers its maximum 440 Nm (324.53 lb-ft) at 2,500 rpm and maintains this constantly until 4,850 rpm. In fourth gear, the vehicle accelerates from 80 to 120 km/h (49.71 to 74.56 mph) in just 4.4 seconds. Thanks to the extremely short gas paths, the sonorous, supercharged V6 responds spontaneously to the throttle, even more so than a naturally aspirated engine of the same displacement.
Furthermore, the new 3.0 TFSI achieves exemplary fuel efficiency. On average, the sedan uses 9.7 liters of fuel per 100 km (24.25 US mpg), and the Avant 9.9 liters per 100 km (23.76 US mpg) – an improvement of 3.4 liters (26 percent) compared with its predecessor. The Audi technology of gasoline direct injection was what made this great efficiency possible in the first place. Unlike conventional concepts, it allows the compressor to be located behind the throttle valve. In view of the low density of the intake air at loads below supercharging level and when coasting, its rotors are free-running and the amount of power required to drive them is low.
Dynamism and efficiency: The new seven-speed S tronic
The V6 power in the new S4 and S4 Avant flows into a six-speed transmission, fitted as standard, which shifts quickly and precisely. As an option, Audi offers a state-of-the-art dual-clutch transmission – the seven-speed S tronic is extremely dynamic and highly efficient. The driver has the option of driving in fully automatic mode or selecting the gears with paddles on the steering wheel or directly with the shift lever – all of which provide impressively quick gearshifts. The gearshift feel is dynamic, comfortable and very precise – typically Audi.
The seven-speed S tronic consists of two separate transmissions and uses two multidisk clutches that control the various gears. The large K1 clutch guides the power via a solid shaft to the pinions for gears 1, 3, 5 and 7. A hollow shaft rotates around the solid shaft; it is connected to the compact K2 clutch, which is integrated within its larger counterpart and controls the pinions for gears 2, 4, 6 and reverse gear.
Both transmission structures are continuously active, but only one is powered at a time by the engine. For example, when the driver accelerates in third gear, the fourth gear is already engaged in the second transmission structure. The shifting process takes place as the clutch changes – K1 opens and K2 closes with lightning speed. This process takes only a few hundredths of a second and is completed without interrupting traction. It is so comfortable and smooth that the driver hardly notices it.
The seven-speed S tronic is designed for maximum efficiency. It operates with very high efficiency and its intelligent control system maximizes fuel economy in automatic mode. With its wide gear ratio spread of 8.0:1 the seven-speed S tronic easily exploits the tremendous power and superior torque of the 3.0 TFSI.
The quattro permanent all-wheel drive system transfers power to the road with supreme ease. Under regular driving conditions, it sends 40 percent of its torque to the front wheels and 60 percent to the rear wheels – a slightly rear-biased, sporty characteristic. Where necessary, it can vary distribution within fractions of a second.
The quattro drive system ensures safe self-steering characteristics, high stability and excellent traction in comparison with rear-wheel-drive competitors.

Pero yo siempre he creido q los S de audi jugaban contra los M de BMW, los AMG de mercedes......no con coches de serie ( por asi decirlo ) como el 335i, es decir, que si lo comparan con el 335i, es que el 335i es una pedazo de maquina capaz de medirse a coches supuestamente fabricados para ser superiores a el, tanto en precio como prestaciones.

No. El primer modelo que ha sacado un diferencial trasero activo ha sido el X6, sin contar los coches de competición matriculados (EVO IX)
Seguidamente ha sido el Saab 9.3 Aero XWD que lo llama LSD.
Ahora le toca el turno al Audi. El S4 estrena el diferencial trasero activo capaz de enviar más par a una de las dos ruedas mediante la actuación de un embrague multidisco en baño de aceite controlado electrohidráulicamente. Esto permite retrasar o incluso impedir la actuación del ESP
