Vorsprung durch Technik

Audi RS4 sedan for the first time I saw the light at the Frankfurt Motor Show 1999. The company immediately announced that the car will go into production, and almost all of the alleged (very limited) output was immediately bought up by the root. In Britain, for example, orders for all the 400 allocated to the country of machines were designed long before the start of production. And this at a price under 50,000 funtov.Pohozhy "focus" Audi AG has once was doing. In 1994 a small series was released wagon Audi RS2 with 315-horsepower 2.2-liter engine, equipped with two turbochargers. The car, designed in collaboration with Porsche, has twice visited our guest ("Action" # 6, 1998, and # 6, 1999), producing a fairly strong impression. And almost all the other products we have Audi "tried" - from the smallest (yet) and A3 models to extended representation A8. Including the modification of S4. The turn Audi RS4 ... A few words about the genealogy of the car. His immediate predecessor - RS2 - basically had a station wagon Audi 80/90, known to our people as a "barrel". In place of "vosmidesyatke" model came A4 Avant, which (more precisely - on the S4) and is based RS4. But if the original RS2 car looks almost no different, on the RS4 does not skazhesh.Vneshnostyu car "came out" - the creators threw unnecessary modesty, for which the S4 wagon was so similar to the A4. First of all notice the flared wheel arches and large 18-inch wheels with small frequent spitsami.Bampery new. The front is equipped with an apron with enlarged lower air intake openings. Secondary supplies air to the radiator cooling system, side - by intercoolers. Originally look "gill" slits in front of the front wheels (which is given through the heated air from the intercoolers) - just like the ring of powerful racing machines. The exterior became visibly present aluminum, from which, in particular, made rails on the roof ... But to end with a description of the external differences, suffice it to say that the exterior body panels of the original car used only for the hood and the hood krysha.Pod - gracefully covered with carbon fiber V-shaped six-cylinder 2.7 liter engine with two turbochargers. Since the motor is to understand in more detail. At first glance it - the same model from the V6 A6 2.7T, which is used on a version of Audi S4. The same displacement, the same number of turbochargers. In fact, the head unit ... in fact, re-designed by the renowned British company Cosworth Technology, which last year entered the cage Audi AG. Increased flow areas, camshafts used to ensure longer opening valves, reshaped combustion chambers. In order to facilitate breathing engine, which requires about 1,000 cubic meters of air per hour, used a more powerful turbochargers Cosworth KKK K04 (boost pressure to 2.2 atmospheres), and intercoolers with a larger cooling surface and the exhaust system with reduced resistance. Plus - a new engine management system. All this can take a 380 hp engine (6100-7000 r / min.) And 440 Nm (2500-6000 r / min.). Power 142 hp per liter of displacement and 235 hp per tonne weight of the car - there is something to be proud. "draft" a car assembly at the factory Audi AG in Ingolstadt, on the same assembly line, from which descend model A4 and S4. The engines come from the UK, with the plant Cosworth Technology. Since the RS4 - a thing "piece-" for the final hand assembly and finishing machines are sent to Nekkarsulm on plant quattro GmbH, a subsidiary of Audi AG, established in 1983 to protect the trademark quattro. (Audi AG insists that the name of a subsidiary should be written this way, with a lowercase letter. By the way, quattro GmbH is the official manufacturer RS4.) On the day of release only a few cars ... once quattro, so - permanent four-wheel drive. Transmission without any significant changes to the migrated model S4. Some alterations were only electronic controls differential (EDL), Stability Program (ESP), brake force distribution (EBD), etc. - The modernization of the brake mehanizmov.Mehanicheskaya six-speed manual is also taken from the S4, but slightly modified gear ratios. Suspension of all-wheel independent multilink, and judging by how low the car is over the road, Short-. Brake mechanisms are now floating type, rather than rigid braces, disk size (360 mm front and 312mm rear) with promises effective tormozhenie.Znakomyas Audi RS4, we could not help comparing it with the car RS2, then A/S4 - all of these models can be ranked to the ancestors. Interior RS2 was richer and more luxurious - just mention "rekarovskie" sports type seats with inserts of alkantry in body color, and a stronger form of the torpedo to set up a sporting way. Torpedo RS4 migrated from the A4, but it looks less "kitsch." To give the sport its charm embellished Sweet Home Alabama - insertion of carbon fiber and chrome rims priborov.Na center console, a lot of space is multifunctional LCD display, which can be adjusted at the desired angle of view - for both driver and passenger. We can see the information about the operation of the background music and navigation. Like we found in the Audi A8.Sidenya this time, too, have a logo, Recaro, but appear to be more restrained in terms of "development" fit and fully trimmed with solid color leather. Behind the wheel comfortably. Seat to the best of hard and keeps sitting tight, and increased in comparison with the S4 range of adjustments can retrieve and comfortable position behind the wheel drivers of any height. Not forgotten and the steering column - it is regulated in two izmereniyah.Na Interior door panels are also present carbon fiber and leather, and the whole interior looks solidly, solidly and stilno.Nahoditsya in the back seat behind the high front riders can, but only briefly. On the other hand, no one did not complain of cramped rear seat in a Ferrari or a Porsche ... The clutch pedal did not seem too tight, move it a little more than the RS2, the time of clutch feels good. Transfer switch with sufficient clarity, the lever is convenient, but the moves seemed too long. The accelerator pedal has a good sensitivity and a nice elastic usiliem.Dvizhenie at low speeds, including traffic, does not extradite essence Audi RS4. The car behaves like a normal city car with manual transmission, the engine easily and almost noiselessly running at low revs. Everything, as in S4. But here in front formed a lumen, and the car literally flew at him, showing stunning overclocking and temperament, and excellent braking devices dinamiku.Na better not to look, and there is no time for it all the attention - I was at a breakneck pace surroundings. In contrast to the RS2, the engine was working as if in two separate modes - a leisurely and explosive, with a noticeable dip between them, the engine RS4, who inherited the character of the motor S4, is gaining momentum quickly, smoothly and confidently, without a hint of just a straight turboyamu.Razgon wild, up to 6000 rpm, then stop fires, and quite "soft", not like on other machines, which then seemed to rest against the wall. Even with the sharp acceleration in the cabin is relatively quiet - sound on stroke vysote.Plavnost leaves much to be desired. On a good flat asphalt RS4 behaves excellently, but that's a bad start, and his charms are transmitted to the body of a severe blow. Joints, chips, a patch and other little things low-profile tires hardly swallow. For the stiffer suspension correctly known rule: "More gas - less than the pits." Tires sing almost any pokrytii.So speed cornering car handles well, though it was not a surprise. RS4 - better handling of the Audi of all we met. The car with the cat's tenacity keeps to the road and diligent obedience demonctriruet when turning the steering wheel and gas pedal (shown here a good lateral support of the front seats). If you exceed the speed of rotation RS4 smoothly into the all-wheel slip, it seemed, with a tendency to understeer, and for adjusting the trajectory enough to work a little driving and extreme conditions gazom.V starts to feel a certain "detachment" from the driver's car - the effect, In particular, the work of numerous electronic systems. But this is - inevitable price to pay for safety behind the wheel. Indeed, the majority of drivers - not professional rally driver, and the RS4 after all is a family avtomobilem.Pohozhe, this road rocket with a decent size boot made specifically for the German autobahns - dispersal dynamics, exchange rate stability at high speeds and the brakes are impressive more than control or response chassis on the snake. If you are the racer at heart, perhaps we could find another car that would be more in line with the specified "mental" property. But it's nice to be on a daily commute to work? Audi RS4 - for those more solid, which ultimately is more important to quickly and comfortably reach your destination, than to feel the nuances of the chassis. Practical, comfortable all-weather car. It is quite harmonious. At the same speed so that the adrenaline is enough. And it will not be thrown shocks and smooth
