Immediacy

Direct-injection gasoline, "double" adjustable valve timing, variable intake tract length with additional vortex flaps ... All these technical tricks allow the new "Six» 3.2 FSI developing 260 hp and 330 Nm of torque - to thrust it's closer to the 280-strong "eight" 3.7, than the previous six-cylinder engine V6 3.0 (220 hp). For example, when accelerating from a standstill to "hundreds", according to factory data, Audi A8 3.2 FSI loses half a second eight-car less! Indeed, front-drive sedan seems to be very dynamic - the engine pulls from the bottom to a maximum of 6700 rev / min exactly and energetic. And his assistant that we should: klinotsepnoy CVT Multitronic. And if you go into manual mode, it is now in the Audi A8 multitronika not six, and seven fixed steps - as in other cars Audi.Novy engine weighs only 170 kg - at least poltsentnera less than the engine V8. So that rotations in the six-cylinder engine rather zanyrivaet. Yes, and in limiting regimes to manage the front-wheel "Eight» Audi certainly easy. It is a pity to see it myself there is no way: moving around a busy Munich, also pours out like drops of vedra.Zato knock on the window - this is the only distinct sound in the cabin. All other sounds are smeared on the audible spectrum, as white on paper - they seem to have, but they are not. No engine, no tires, no aerodynamic rustle do not attract attention. Even with heavy acceleration is felt that over the acoustic comfort of the Bavarians have worked in osnovatelno.No That's the highlight of the A8, that even with a model of sound insulation and the status of top-model car is different immediacy in communicating and provides a very high quality feedback. She - and the profile stiffness multicontour seats. In the low landing sports. In fact, as arranged around the driver's controls. In the optimal level of the jet, which provides power steering, and a good compromise between smoothness and feel of the road, found for an active air suspension with several fixed modes amortizatorov.Kstati rigidity, it appears that the chassis Audi A8 is not specifically adapted for a light motor and front-wheel drive - Electronic air suspension is versatile enough to independently calculate the required changes in the shock absorbers and pnevmoelementov. And although Audi engineers claim that the air suspension on the A6 model is technically more perfect, the chassis of the A8 still makes a better impression - as if it's polished, has been brought "to the bell." The machine does not just seem sportier, more aggressive - it seems to be firmly on its feet. A relative rigidity even on Russian roads does not interfere with "a-eighth" in every movement, as in every last detail, to be driving higher klassa.Nu, or almost everyone. Flimsy paddle levers here evoke the same confusion as in the A6 saloon ... Another novelty - Audi A8 4.2 TDI quattro with the latest biturbodizelem, which in Ingolstadt immodestly called the most powerful diesel "passenger" motor. If we argue formally, then 326 hp power - it is really more than folksvagenovskogo turbo V10 5.0, a new mersedesovskoy "eight" or a 420 CDI biturbodizelya BMW V8 4.5. They did develop the "only" 313, 314 and 300 hp respectively. But the magnitude of torque diesel Audi loses them all at 50-100 Nm! Until the tachometer needle will not pass the mark 2000 rev / min, thrust really is not enough: if the car crushed the big fluffy pillow. But then two-ton sedan just leaps forward, building on the asphalt all four wheels and pripechatyvaya riders to their seats. And do not call God grant you that genie in some high-speed bend with disconnected system ESP. Not even four-wheel drive will help with Thorsen - sliznet car off the road like a cow tongue. Directly to the vector tyagi.Ta ease with which diesel sedan sprints on the autobahn to the maximum speed, inspires. I'm even willing to put up with much higher noise level in the diesel car as compared to Audi A8 3.2 FSI - so very angry growls here engine. And the exchange rate stability to "maximum speed" is amazing. But hovering above the road, be ready for the unexpected. Look how rapidly approaching old Opel, came out in front of me to overtake - it seemed to increase the digital zoom, though in fact it is speeding at 150 km / ch...Tipichnaya situation for the German autobahn, where the air needs reliable, powerful brakes. The slowdown is growing along with the brake pedal, but not as fast as we would like. Damn, where is this turbo jet in reverse? Several of these slowdowns - and the brakes can overheat. Audi engineers to this problem seems familiar. Therefore, in Munich, they showed a new ceramic discs firm CGL Carbon to the sedan Audi A8 6.0 W12. By construction, the "Ceramics» Audi to a tee is the same as for cars Porsche (see AR № 11, 2005). The only difference that the calipers are not here four-and шестипоршневые.Преимуществ have ceramic brakes are many: more than two times less mass, better performance, virtually immortal performance under cyclic loading. And wear is so small that it is measured by weight - Audi engineers say "ceramics" is at least four times longer than the "iron". Drawback, in principle, only one - the price. But the big one. If you order a "pottery" at the factory, the German buyer, it will cost not less than 8,000 euros! And if you install ceramic brakes instead of full-time, it will cost even more. And in addition need to reprogram the ABS control unit and ESP.Neuzheli this is the demand? As we are assured by Audi - huge! Like, now engaged in a similar tuning many private studio - and fight with the owners W12 twenty thousand euros. And we have - just eight ... Here also offer pre-test "pottery" in the case. But the exercise test was strange: it was necessary to accelerate long wheelbase A8 6.0L alleyke the narrow, drive to control the alignment of the cones and that there are forces vlupit on the brake pedal. On the odometer at this point - no more than 120 km / h. Yes, and hail started! But even if the wheels were dry asphalt, to understand in this mode, it still does not - because the "cold" ceramics is the same as conventional brakes. To really appreciate its advantages, you need to repeatedly pull up the car at high speed - just as manifest resistance composite brakes to overheat. Let me go back to the highway and return to that old Opel! Unfortunately, I missed another event, which the Germans attach great importance - not to hear the new sound system Bang & Olufsen, which will soon appear on the Audi A8 as a custom-built equipment. As they say inveterate audiophile, the sound from Bang with Olafsenom used to be mediocre. But the design - everything is in order! Here and in the Audi: fourteen active speakers in a closed "offices" under the graceful aluminum caps, sly acoustic prism-twitter, which leave from the front panel by means of servos. A kilowatt-plus power output and sophisticated digital signal processing, taking into account the ambient noise, which are fixed two remote microphones. Cool! Now I have to wait for the new year - before "eight" with the acoustics of B & O will not get to us. But cars with superdizelem in Russia we do not see - because they set the diesel particulate filter, which is sensitive to all sorts of rubbish in our diesel fuel. In America, by the way, Audi with its diesel engines are also not in a hurry: while the Mercedes involved in the introduction of synthetic urea to control nitrogen oxides, Audi engineers have experimented ... with variable valve timing. So far, all engines with compression ignition does not need them. But in Ingolstadt think that fit into the rigid emission standard after 2010, it will help them fazovraschateli.Posmotrim! But buy a Audi A8 3.2 FSI petrol "direct" the engine will be in mid-August. Prices front-wheel drive sedan A8 3.2 with CVT Multitronic start at $ 94 763. Long wheelbase version is more expensive - from $ 98 111. A little later, will be wheel-drive version with six-speed "automatic". But best of all, that the FSI engine will be installed on other cars and Audi. True, the delightful supercharged "Quartet» 2.0 TFSI, which has recently recognized as the best engine in its class, yet remains a taboo subject. But the main thing - the ice was broken. You'll see, will live up to the appearance in Russia of the future with Audi S6 V10 FSI engine insane from Lamborghini Gallardo! What good fuel we already have. We would have more decent diesel
