In a raised voice

Why did you refuse the motor 2.7 Biturbo, who had previously installed on the Audi RS4? Why the new version of the charged "quartet" is aspirated engine V8, rather than, say, V6 3.2 FSI turbo? - Ask a question Jurgen Jablonski, chief of engine development company Quattro GmbH .- Oh, this is a demonstration of our capabilities. The fact that we can offer a great turbo, no one doubts. But many prefer the atmospheric engine (here Jurgen would say "atmospheric engines prefer BMW»). So we decided to show the world that we are building on the shoulder than air motors. To increase the power we have raised the speed limit to 8250, using the same technologies and materials that are used to sportprototipah: Pistons in our motor move the same speed as the engine in Formula 1! But it's true! Of course, Audi engine is not designed for 18 000 rev / min. But at 8000 rev / min pistons fly in the cylinders, as in the following formula: Stroke engine in Audi - 92,8 mm, and the formula - about 44 mm. That is the maximum speed of the piston and there, and there is close to 25 m / s! In another way - short-stroke engine with cylinders of larger diameter (as in Formula 1) simply would not fit under the hood Audi A4. Yes, and this engine was not easy to attach all niches hood space filled with attachments, hoses and control electronics units. Phase Control System helps give 90% of maximum torque in the range from 2250 to 7600 rev / min - and this, combined with a perfectly functioning mechanism gear, allows not only accelerate with confidence, and revel in the crackdown. Juicy baritone to mid-range passes into the uterine growl at the top. This V8! Any such luxury turbo sound, and not dreaming. And, if I had the Audi RS4, I would never have gave him "tuners" to experiment with the "acoustic" exhaust ... The more so that I can do the tuning myself. Button «Sport» on the wheel increases the sensitivity of the accelerator and drive simultaneously opens two flaps in the exhaust system, increasing the volume and changing the tone of the exhaust. Audi RS4 is now approaching could not hear for two quarters, but for tri.Transmissiya here, of course, all-wheel drive, Quattro - permanent four-wheel drive and limited-slip center differential Torsen. But there is one highlight. If before the torque evenly distributed between the axles, it is now supplied to the rear wheels have 60% of the time (the same path were the creators of BMW four-wheel drive station wagon and Alfa Romeo Crosswagon). This is done to reduce the tendency to drift Chuck, a sin-wheel-drive Audi. Of course, on public roads, and even on dry pavement feel the benefits of an asymmetric torque distribution is not easy. Another thing - a closed circuit on the range of Pirelli near Milan. There can be assessed and RS4 on dry roads, and wet. The "limit» Audi RS4 is great. How easy car zanyrivaet in sharp turns, as surely lick landmarks on the snake! Of course, excellent handling - not only the merit of the transmission. Played a role with the suspension system antikrenovoy Dynamic Ride Control, familiar to cars Audi RS6 (it's shock absorbers with automatic variable resistor), and power steering with excellent feedback. The stabilization system intervenes in the management process at the last moment, no loss of fun to drive fast on the highway ... At first I was afraid of car circles, and then ... In the management of the car is absolutely clear and transparent. With the increase in fuel RS4 goes out of rotation, a discharge - a little screwed into the skid. Such a character does not allow early opening gas at the outlet of the turn, but - no scary drifts. A high-speed arc? On the speedometer - 160 km / h, the maximum lateral loads, but the Audi RS4 is simply behaving correctly! Excellent balance! With brake problem was only one: at first I could not bring myself to slow down before turning on 5-10 meters later. Instinct ... Who knows what the front are eight-calipers. Who knows what this "floating" perforating wheels! Need to try it yourself - and make sure that the brake performance is not reduced by a couple of laps, as it did in testing Audi TT. Tried. Convinced. Slowing down - not only effective but also safe handling confirmation stabilnoe.Kosvennym Audi RS4 was the fact that the water-drenched track was not a single accident! The only serious departure from the road with damage to the body was on account of race prototype Audi A4 DTM - car operated in a racing taxi as well at the wheel was an experienced pilot Dindo Capello. But after twenty laps, when the tires are pretty ragged, the car left the road - and ran into a bush, behind which, when turned out on a strong metal stand was the instrument weather station. For a while, the staff will determine the Pirelli site weather conditions at the face or over the Internet. A team mechanic will have to repair carbon fiber bodywork. Neither the driver nor the right of a Russian journalist who was sitting not postradali.Sluchis the same accident with the Audi RS4, too, nothing bad would happen. In addition to front airbags driver, there is a window-curtains, which are inflated gas generator that supports the necessary pressure for a few seconds - in case an accident does not end just one hit, and followed the coup. But side airbags in the RS4 is not at all - the body of the driver and passenger side impact protection seat itself, and this is one of the most striking sights of the new RS4. Seats look as good sports "bucket" - a four-point seat belts at the windows, with the developed "ears" of lateral support. The position of these "ears" can be adjusted by the actuator, and when the driver presses the «Sport», they are automatically tightened - converge at the center of the third turn. One problem - for this seat, I was too big: too tight cushion. Fortunately, the proposed so-called comfortable seats - no holes in the back, but with a full set электрорегулировок.Украшает salon and "racing" steering wheel - with flattened bottom rim. But when you start to turn the steering wheel at large angles, even with the interceptions, finished with a slippery plastic shelf annoying. By the way, rapid rotation and prevents the steering wheel that power lightly it "bites". But on the track ... I'd have worn, winding round and round. But the commissioners threw the checkered flag. Now - on public roads. It's a shame, of course, that the surrounding Audi RS4 does not make any impression. When ryavknesh - turn around, and ... And so - this is a great sports car for every day. You can ride safely, you can go quickly. And you can - and very quickly. And the special charm of the machine in that it does not impose itself, not to aggressive aerobatics podzuzhivaet. You just believe in yourself and in your car. Yes, it shakes. But if we compare the Audi RS4 with cars like the BMW M3 and Porsche 911, then most likely, Audi will komfortnee.Prays list for Russia is not yet formed - RS4 will have until early next year. But, proceeding from the price of Audi S4 ($ 90,000), we can assume that the Audi RS4 will cost $ 110-115 thousand wonder what it would cost the new BMW M3 or Lexus IS500? It's most direct competitors - and he and the other go to market with new V8 engine is not less than 400 hp
