Audi TT RS with 340 hp in the Super Test: on coupe with five-cylinder turbo Track

The 1994 after 20 years ended with the Audi RS2 era of Audi five-cylinder engine experienced an impressive renaissance: the 340-hp Super Test candidate Audi TT RS is waiting, the first classic sports coupe quattro GmbH not only with all-wheel drive, but ties with its characterful five-cylinder -turbo also the times of the legendary Sport quattro S1.

The widely used in team sports, supported by mutual hand fives Ritual "Give me five" is busy in his stressed mood-enhancing effect similar positive as this country expressed on other occasions quip, sometimes all a blind eye to make his straight. From a physiological perspective, the number is five not insignificant what the man will certainly like to confirm from the sawmill. Only in the school's five spells trouble. But after five still the six-threatening, and we can deduce that the five is better than six, we accept the school evaluation system, for once, as a coherent, also in terms of engine configurations consistent appraisal model. 

Five better than six? This ranking, the majority of motor popes and with them the front of the car salesman would probably close emphatically. but applies the five-cylinder engine since its discovery as the amputated version of the traditional antretenden with a big image advantage six-cylinder engine. True to the motto: Who owns a six-pack that has brought it to what. But underprivileged, as is often assumed by noble side, the five-cylinder is not: after all, he is more in relation to the safe quantitatively well equipped with a cylinder in the spread forever unassailable four-cylinder.

Last five-cylinder turbo in RS2 1994

More than a four-cylinder, but less than a six-cylinder - in times when downsizing is no longer taboo in the higher classes of vehicles, the number has five as a forward-looking compromise in terms of number of cylinders but literally, right? Among connoisseurs of matter the enthusiasm potential of this engine type is certainly known for some time, though the circle of those who with the legendary, 306-hp Audi Sport quattro from 1984 or the last five-cylinder turbo, the RS 2 of 1994, closer were allowed to get in touch, but overall has remained quite small.

Pikes Peak victory by Walter Röhrl in the five-cylinder model

The long break between the sports estate even asked towards the end of the era with support from Porsche to the wheels - the way the founders of the vehicle class of the sports estate - and the current, set up by the Quattro GmbH in-house Audi TT RS is probably due to the unfortunate circumstance, that the five-Ender fell as an intermediate solution between the popular four- and six-cylinders image moderately through the grate - although his motorsport career with the unforgettable Pikes peak victory by Walter Röhrl in the 600-hp Sport quattro S1 with the winning performances in the American IMSA GTO is blessed with almost legendary highlights.
 
But in fact the series of five is because of his unorthodox spark gap of 144 degrees and its peculiar firing order - 1-2-4-5-3 - and the resulting at higher speeds second-order mass forces technically more fraught with compromises more than a six-cylinder - what the fan base but did always emphasize as character-forming element. With special torsional vibration damper on the crankshaft, the refinement is already long no longer an issue. What remains is only the inimitable rhythm that the original engine type is accompanied a truly beguiling musicality for the best. 

TT RS reminiscent of old times Group B World Rally Championship

Who has heard ever the creamy, warm and sonorous roar of the Sport quattro, is located in the TT RS - feel immediately transported back to ancient group B times the World Rally Championship, when dealing with - albeit in muted volume and socially acceptable despite Sportauspuff a goose bumps announcing generating wastegate pipes, fire-breathing Allradler under Röhrl and Co. as a land-based missile competition taught fear. Objectively considered today it is still - or even more so - to give easy for the five-cylinder, the approval: First, it convinces with its considerably smaller pack size, which makes it ideal even for transverse installation in confined engine compartments. The cylinder spacing is only 88 mm, and also the laid inside the main bearings of the crankshaft contribute to that the Motorenmaß does not exceed the length of narrow 494 millimeters. 

On top of the weight advantage: With 183 kilograms, he is only 30 kilograms heavier than the two-liter four-cylinder from the TTS 2.5-liter engine. Thanks to the previously used exclusively for the large TDI engines, high-strength compacted graphite, font for the crankcase of this line five-cylinder is also significantly lighter than a comparable six-cylinder engine displacement. Even otherwise, this long-stroke engine is not bad: giving good service that the engine is in fragment-like similarity has long been in the VW Jetta North and Central American origin, is all the more remarkable given that he by no means makes representations in its present form with fussy character traits, but a has achieved technical brilliance to it - at least theoretically - could open up the wide world of motor racing as it was then. 

492 grams, the piston made of cast aluminum, forged connecting rods, sodium cooled exhaust valves for each 42 degrees hydraulically adjustable camshaft with two-stage chain transmission (the current of a particularly quiet toothed chain, a roller chain, and an intermediate gear is) as well as, of course, TFSI-injection - all on extremely compressed space and also processed visually very attractive. Finally, also contributes to the unusually large-sized turbocharger, the compressor wheel comprises at least 64 millimeters in diameter and can be up to 335 liters per second compress air at full load, to a result full of positive surprises.

Sprint to 100 km / h in 4.6 seconds

The hope or fear to experience a similar digital power delivery as once in around 720-hp, 2.2-liter Sport quattro S1, the IMSA series, confirmed in dealing with the current 2.5-liter turbo of the TT RS, however, not, though even here a power supply is present, which can eliminate the risk of a disappointment in its entirety. PS 340 and the maximum torque of 450 Newton meter, which is available from 1,600 / min fully available to represent a service package, which is likely to emphasize the predominant virtues of the wheel drive vehicle sustainable. But with all temperament that manifests itself, for example in the sprint to 100 km / h in a remarkable time of only 4.6 seconds, the TT RS is a high level of skill in the face of adversity, which holds the public road. 

In other words, he feels absolutely civilized, floats relatively unobtrusive with - and not annoying. On the contrary: The top model of the TT series evokes lasting driving pleasure and makes its practical aspects as self-evident to the fore as his brothers from volume production. What is obvious, but he shares with those most of its technical substance. The fact that it has the TT RS as a sly old ears, most outsiders remains hidden regardless of the front, rear and sill area but significantly sportier look - at least as long as they with 1483 kg not too heavy guessed quattro variant not in full get action to face. For then - at higher speeds and the appropriate dynamic - the affable sports type peels with its distinctive five-cylinder sound formally from everyday dress and sends extremely toned, polished and confident to beat not only the operating at the same performance level opponents cheat - he beset also significantly stronger. 

Nordschleife lap time of 8:09 minutes

What the TT RS has in the stocking, shows once again on the Nordschleife, where he is preparing with a sensational time of 8:09 minutes to put even the big brother R8 4.2 downright unabashed onto the tin. And mind you not with sport tires, but with conventional road tires Michelin Pilot brand sports in the special size 255/35 ZR 19 (Here are all the Super Test lap times on the Nordschleife) The defendant on the small track in Hockenheim, clearly pronounced tendency to understeer falls on the faster mountain and valley distance of the Nürburgring naturally less significant. The driving safety generated by the understeering interpretation transforms the TT RS on this terrain in an almost hündisch obedient being that so obedient bends the will of the determiner that the unconcern prevailed rapidly over all trials and tribulations. The beauty of it is that the formerly among his more civil predecessors complained wheel drive behavior - prancing around the vertical axis when the load changes and as yet criticized the TTS, counterproductive intervention actually off ESP - has the TT RS entirely deposited in favor of a liquid, elegant sports style , 

He puts his potential in exactly the route in the spotlight that comes to customary conditions and circumstances of public traffic the next. Pushing mainly caused by its front-heavy weight distribution over the front axle in slower corners and bends, then, watched him especially as the lap time at Hockenheim taken (1.15,0 min) for also does not justify disappointed faces. Nevertheless, also the TT RS is not the all-round super talent, as he is often exposed. That it is the wet element calculated in which the An incoming with a standard electronically controlled and hydraulically actuated multi-plate clutch, and therefore in theory the best armed for such conditions Allradler affords a faux pas is insofar unhappy, when such a presence by the experience of the TTS not be looking in the system, but rather in the tire sector. 

The tire choice were time-wise no differences

The fact is that the TT RS - like any austrainierte athletes - sensitive to the soling. A trial-by-step conversion of Michelin Pilot Sport to the new generation ContiSportContact 5 P resulted in wet handling test, although to a significant weakening of the phenomenon and also to a measurably improved time - but the trend remained unchanged: The TT RS tends to swerve the tail with little warning. So while the An incoming with baugleichem drive TTS Super Test responded on a wet track with striking push, the TT RS pushes so vehemently to the rear, it is advisable that insurance in the form of the now excellent because working subtly and with high efficiency ESP not completely terminate under these conditions. 

That there in the two sporty tailored tire options, Michelin has given in 19 and 20 inch Conti, shifting the center of gravity with the aim of further improving the dry grip, is obvious. The respectable lap times on both the ring and at Hockenheim where exactly the same lap time were driven to the tenth of a second with both types of tires can be no other conclusion. Consequently, it was obvious that the TT RS had to go out in the final discipline somewhat out of breath. And since we know that a sports car can only be as good as it allow its tires, we want to use this incident as an opportunity for once to utter the achievements of electronics our blessing. Seen in the light but such peculiarities involve a residual risk. Because that falls electronics - once again - the thankless task of compensating for a weakness in hardware.

The safety stressed tendency of understeer tendency is the TT RS on the Nordschleife so far benefited when he is presented with an absolutely foolproof handling. to throw him off course would be to do everything wrong, what's going to go wrong. The inspiring commitment is expressed not in vain in an excellent lap time, which is even well below the Porsche Cayman S. Speed ​​257 km / h on the Döttinger height are already a word.

The succession with two different types of tires (Michelin and Continental) driven tests showed time-wise, amazingly, no differences - although significant differences in driving behavior were noticeable. With the new ContiSportContact 5 P comparably high level of safety the understeer was significantly less pronounced. The driving pleasure would through a basically neutral vote but surely still be increased.

The much broader, fixed rear wing had its effect not: Compared to the TTS (Super Test Audi TTS) has become significantly better aerodynamic balance. Although the lift on the rear axle now goes toward zero, he is also on the front axle, albeit marginally, reduced - from 420 to 358 Newton now. The aufnickende moment is now, however, increased slightly. A large contribution to the overall improvement in results can be attributed to the front apron and the effective spoiler lip. Amazingly, even the Cd value (0.31) so that even better than the TTS (0.32).

The spontaneous enthusiasm in the face of extremely agile stroke steering can be for something as soon as tighter turns to be addressed under load. Then that is a lot of understeer is the result. you work against it - as practiced in the slalom - consciously, the four-wheel drive shows with load changes generally quite accessible. The little easier expectant tail always provides good control on course, which is why an approach to the limit can be mastered safely. Faster than the lighter to a concise Zentner TTS RS variant is not here though.

Unlike the TTS but the engagement mode is much more moderate. Electronics and driver so do not necessarily work against each other. The defendant in the four-cylinder tendency to hunting has not determine the TT RS. He remains on course when tends always easy sliding even under load on the front axle.

It depends less on the concept, but rather it from being implemented. This thesis is based of the all-wheel drive TT RS like no other. During the TTS at these low coefficients of friction stoically pushed through the front wheels, and so even the possible advantage over the weaker, front-wheel-driven two-liter variant abandoned, the current TT RS is a completely contrarian image. The abrupt breaking of the rear axle with low friction values ​​is sometimes not only high demands on the driver, but also brings the powerful coupe and temporally strongly behind. It lacks almost five seconds on the TTS. So it's not advisable to disable the ESP in wet conditions.
