The engine is got with such sound as if its grandfather was the loud rude fellow 5.7 V8 from Corvette. It starts to grumble with single turns and if “to throw” an arrow up to 5000 rev/min ravens get from a heart attack. But when the echo from low-frequency muttering 4.2 V8 will abate, you already will far. Up to 100 km/h RS4 it is dispersed for 4,8 with - as quickly, as superpenalties Porsche 997 Carrera S. Start from those turns when voice V8 battles birds, and you receive desired dimness in opinion of. The full drive “drives in” capacity into asphalt with such force, that proslipping is extinguished in a germ, therefore dispersal develops redoubtable. The first transfer comes to an end soon, on the second you have time to notice, that the motor turns devilishly quickly and it is time “to tuck in” third, then you look at a speedmeter: 160 km/h have come through 16,6 with after start! But the reason already was on sale to feelings, and the leg persistently “trambles down” a pedal of “gas”. In a head the idea on the maximal 250 km/h is carried by, but RS4 already hangs on an electronic collar - 250 km/h become a reality as suddenly, as those of 160 km/h. Reading these lines, you for certain think, that RS4 is indeed very fast, but hardly you represent how much!
Now we shall reduce rate to check up, how this high-speed V8 will pull on “bottoms”. Audi approves, that 90 % of the maximal 430 Nanometers are accessible in a range from 2800 up to 7600 rev/min. We shall lower up to 2000 rev/min, we shall include III transfer and … we are again born as scalded, and the arrow of a tachometer again steals up to 8000 rev/min! The same history on IV, V and even VI transfers. In it the motor which fights in ecstasy after 6000 rev/min also powerfully picks up on low turns is trusted hardly, but.

The designation “ 4.2 V8 ” seems to friends, figures 420 h.p. and 430 Nanometers too hint on family RS, but look at the characteristic of a set of capacity: the maximal feedback is reached at 7800 rev/min, and the terminator of turns works on 8250 rev/min! In civil understanding it is other-wordly frequencies of rotation crankshaft the 8-cylinder motor. Honda does something similar for versions Type-R, but, similar, to Japanese it is better stand in side with 2-liter “four”. The unique costing competitor - 5.0 V10 from BMW M. It has the same liter capacity and is untwisted up to the same high turns, but there are the nuances, forcing to speak about engine Audi in a superlative degree. About them hardly later for now it is possible to bring the first results.
So, why for new RS4 the atmospheric motor has been chosen? First, because present technologies Audi (speech not only about direct injection of fuel FSI) allow to achieve high capacity without application of complex, bulky and heavy system of a turbo-supercharging. Secondly, here again it is necessary to give due FSI, engine RS has unknown for V8 parameters of fuel profitability. Thirdly, this 4.2 V8 is more compact and easier former 2.7 V6 biturbo! So now concept RS means not only capacity and drive, but also high technologies. And it is not similar to gipsy Mickey …
Appearance, as before, hides true speed of the car. You look on RS4 and you think: here Audi A4, only something in it not so. As though the honours pupil-bore who always avoided lessons of physical culture, after summer vacations ten times was tightened on one hand. No, perhaps, all twenty. Thus its appearance has not changed almost, but forces aloud has increased. Here and Audi RS4 it is constructed in the same body, as A4, but wings were distributed at width, thresholds and bumpers why “have recovered”.

Tuning versions resembled a sound leather sofa with the jet engine, however RS4 there was no quickness in turns a little. Because of the heavy motor located before a forward axis, and all-wheel drive transmissions with symmetric distribution of the twisting moment controllability RS4 became a stumbling-block in dispute with BMW M3. Therefore development new RS4 was conducted under the control of “dietician”. But before, in 2002, in number RS happens updating - Audi RS6. The first RS with a body a sedan both hydro. Is and Avant, but the sedan has been apprehended by a target audience with enthusiasm. On installed power per employee it has pin down even, apparently, invincible BMW M5. The motor 4.2 V8 with two turbines gave out 450 h.p. and 560 Nanometers so to be dispersed from a place up to 100 km/h more quickly than for 5 with for RS6 not a problem. On wet road the system of a full drive helped, and “automatic device” and a suspension bracket with shock-absorbers Magnetic Ride provided to the car necessary comfort in a business class. However turns became even more artful, and increase of the prices for fuel has called into question an invention with turbines. And nevertheless the message about change of the motor concept for new RS4 has appeared sensation. Farewell, turbines, long live the atmospheric engine! Once it have told in BMW, but we did not expect such step from Audi, whose sports traditions go back to turbo Quattro. Really the charge of fuel really matters for the present driver’s car? Today it so, but is also other opinion in occasion of radical change of the concept propulsion engineering.

Four driving wheels, four armchairs and eight cylinders Audi RS4 can force to reflect on expediency of purchase Porsche
In 2000 Guy Richi maked movie “Snatch” where one of the leading parts - gipsy Mickey - Brad Pitt has played. Eccentric and arrogant Mickey once was stuck in history. Instead of holding the emotions on the lock, Mickey it was imposed on fight with Magnificent Georges - lanky fellow from the world of illegal fights. Looking at it, it is easy to present, as quickly from Mickey should make a chop. But the matter is that this thin guy carried a nickname the Master of One Impact with which it has confirmed and this time. One impact - and burglar Georges has appeared in hospital with a trauma of a head. I have recollected Mickey because have just swept in its four-wheel double - Audi RS4. The car which looks almost as usual Audi A4, but knocks down almost as Porsche 911.
To begin costs from history. In 1994 has appeared first car Audi with a designation “RS.” Avant Audi 80, created for respectable European families, in the center of preparation Porsche “implanted” 2,2-liter turbine motor capacity 315 h.p., 6-step manual gearbox, a full drive quattro and abrupt brakes with brand Porsche. Something has changed in appearance and interior, but the most important is dynamics. Dispersal up to first ” hundred ” borrowed 5,4 with - even to present measures result impressing. In 1999 Audi lets out one more sign Avant - RS4. Conceptually it was copy RS2, but due to greater capacity and excellent technologies went more abruptly other Porsche. A secret of its tremendous dynamics - 380-strong motor with two turbines  which were dispersed with the car up to 100 km/h for 4,9 with.
