The two-liter turbo

Cool the motor. Traction from the "bottom" can sneak a cat almost at idle, it is surely accelerating in top gear for quiet, smooth bass rumble. Nearly two thousandth mark on the scale of the tachometer work smoothly enters turbocharger, and - a powerful, good acceleration up to the electronic "clipping." But what is DTM? No doubt, Audi racing championship in the German Touring prototype Deutsche Tourenwagen Masters is now in the lead. In addition, the combat looks really Audi A4 DTM styled serial sedan and even has one thing in common with body parts. Kryshu.No for a serious man who is able to distinguish between form and content, an association with the DTM should call the powerful Audi RS4 with a 420-strong aspirated "eight", as in a ring around the car. And is not this front-drive A4 with a four turbo engine 220hp .. not that power was not enough. No, it is enough. And the sporty, nominally, is also present. Anatomic chair, like a racing bucket. "Dropped" in the 20 mm suspension rigid wheel is poured, "weight" - with the exception of near-zero 'dead' zone. Six-speed gearbox with a short lever topped with a nice ball, pereschelkivaetsya clearly. In addition, A4 DTM Edition can be ordered in the version of quattro - for $ 60,300 instead of $ 57,000, for three thousand dorozhe.No "quartet" of Ingolstadt, even with the stiffer suspension - it's not "treshka" from Munich. This is the third series in the BMW driving feel the pilot. And Audi's shaking at the seams and joints simply do not justify the slight improvement in handling - especially on our roads. It's just a compact business-class sedan with a powerful, flexible and cost (if not to trample the trigger) turbo engine. In the version of quattro - what is needed for Russia! And if we remove from the car all this psevdogonochnuyu jewelry, return to the normal suspension ... and this car is - it's just A4 2.0 TFSI (from $ 44,500 for front-wheel drive and $ 47,700 for quattro). True, the 2.0 TFSI engine is "normal" and develops 200 forces - and not 220 as in the DTM Edition.Voobsche, from a variety of options and combinations of engines and transmissions in the price list Audi head is spinning. For example, Audi A4 quattro can buy not only the $ 47 700 (2.0 TFSI, 200 hp), but for $ 42,000 - is the same "four", but good old turbocharged 1.8T. Yes, in Russia, both turbo will be sold in parallel - and the old 1800-cc, and a new two-liter! The difference in price, as we see, nearly six thousand. But since the "old" 1.8T delivers only 163 horsepower, then from a marketing point of view it is quite opravdano.A there is also Audi A3 2.0 TFSI quattro - and also for $ 42,500, I rode on a "three rubles." The engine develops 200 forces here, but the car accelerates angrier and more dynamic than the 220-strong A4 DTM Edition! Of course, "treshka" easier. But I went to the all-wheel drive A3, which weighs about as much as the A4 DTM Edition in front-wheel drive version. So it's not in the mass. And for what? In the setting of electronics? Maybe ... In short, if you want to feel the anger of the new turbo sport - this Audi A3 2.0 TFSI. Pity that the rudder at A3 "pustovat", and the brake pedal is scary, "falls" under the foot, with vigorous contraction. But what acceleration! By the way, the only all-wheel drive and a powerful alternative to the "premium-class golf," in addition to the Golf GTI, can only be used Volvo S40 T4 AWD - among other things, with a similar clutch Haldex electronically to drive the rear wheels. And with very similar tsenoy.No If you choose to Audi A3, then - with only the "mechanics"! But not with a robotic gearbox DSG. This unique preselektivnuyu transmission with two clutches, we still only praised - for vehicles with six-cylinder 250-horsepower 3.2 She is working really great. But on the Audi A3 2.0 TFSI box produces quite a different impression - as if the "brains" to control DSG turbo just is not rebuilt, leaving the algorithm to V6. Move smoothly and adequately accelerate almost impossible! And the most balanced in all respects - the dynamics, the handling, at a price - of all cars with an engine 2.0 TFSI sedan struck a large Audi A6. The engine develops only 170 then forces - now it's "basic" power to vsefolksvagenovskoy turbo "quartet" (for a motor 1.8T "minimum" was 150 hp). Cars sixth series sedan and station wagon Avant, with a 170-horsepower turbo engine are just front-wheel drive and automatic transmission as proposed here Variator multitronic. On the "Variable speed" car did not go, but Audi A6 2.0 TFSI with the "mechanics" - a decent option! Not for the racers, of course. However, the acceleration time from 8.4 "up to a hundred", and 227 km / h "maximum speed" is enough when it comes to large prestigious car for just $ 51000.Bolee, the 170-strong "six" very nice run - softness in her character and smoothness are combined with accurate and informative. Calibrated all: response to steering, smooth ride, responses to pressing the gas pedal and brakes ... I remember even the powerful and super-expensive Audi A6 4.2 bring less joy. Apparently, the chassis of a "six" is that favors lighter dvigatelyam.Interesno that A6 2.0 TFSI (170 hp) and A6 2.4 with naturally aspirated engine V6 (177 hp) are available simultaneously - and thus very close power and affordability. Why? How to assure Audi, these machines are completely different buyers: people of retirement age prefer six-cylinder with a smooth, flat work, and younger customers - turbo. But I must say that due to counterweight shafts "four" not at all annoying vibrations. A character in it, again, very soft and flexible. The only problem - if messy start or try to "pull" in second gear with the most-the lowest speed, the engine may stall tough with such a blow, though begun in tsilindrah.A backfires in the rest ... Not for nothing that my colleagues in the International Engine of the Year competition was awarded to this motor victory in the "two-liter" class, not zrya.Kstati, as we are assured ingolshtadskie dvigatelisty, turbo calmly "digest" the AI-95, and if necessary, can operate normally even at the "ninety-second "gasoline. For example, the 150-horsepower naturally aspirated 2.0 FSI engine with its compression ratio of 11.5 work on the AI-92 - is generally an emergency mode. A compression in turbo though large in supercharged standards (10.3 in the 170-strong version, and 10.5 in the more powerful versions), but in combination with anti-knock control allows you to do from filling, "ninety-second" tragedy. "Hear" electronics detonation, lower boost pressure - and drive yourself calmly on. Most of the loss in power, even not zametit.Krome of turbo from the start conceived as running on a conventional (so-called stoichiometric) mixture. And do not lean on as the engines naturally aspirated FSI. So - no problem with an excess of nitrogen oxides NOx, and a special catalyst, which is dying from an excess of sulfur in gasoline Russian ... But the interesting thing is that the naturally aspirated FSI engines now also a "stoichiometric"! In this reluctantly admitted spokesman engineering department Audi. It appears that Volkswagen has come on the same rake as the Mitsubishi with their GDI engines of innovation in the mid 90s. And they both were convinced that the lean-burn engines - is the future, it's fuel economy and fighting global warming. Actually, it turned out that when taken in Europe, driving habits and road highways rhythms of "immediate" motors in the "lean" mode malonagruzhennyh work very little. Benefits - no, some trouble with the expensive converters. Indeed, precisely because of them nor Volkswagen, or Audi, Skoda or a long time did not deliver large quantities to Russia motors FSI! Now been fixed. Structurally, the engines have not changed - they just reprogrammed the control algorithms, eliminating the "depleted" mode, and removed no longer needed a special converter for NOx. So now from the "operational" gaps remained FSI only need a high-octane gasoline and high cost of petrol pumps ($ 260 per auxiliary and $ 440 per core) and nozzles ($ 240 for a little thing) in the case of replacement after three years of garantii.A what to do? High-tech gift is not given by
