Audi Sport quattro S1 INTRODUCTION In 1983, Audi had anticipated that they would not be able to rely solely on their traction advantage and overwhelming horsepower to win rallies for much longer. In mid-1984 their predictions rang true with the arrival of the smaller, purpose-built, mid-engined, and four-wheel driven Peugeot 205 T16. The quattro in comparison was large, front heavy, and suffered from crippling understeer in most driving situations. To fix this, most of the engineers at Ingolstadt proposed that they should design and build a totally new Group B car from scratch. However, Audi’s top brass was not keen to the idea since it would have given bad press to their flagship quattro model. Hoping to save face, the car had to be “fixed” and improved substantially, but not replaced. The answer was to be the Sport quattro. QUICK BROWSE CONTENT HISTORY E2 EVOLUTION RALLY CAR SPECIFICATIONS HOMOLOGATION MODEL ROAD CAR SPECIFICATIONS HOMOLOGATION PAPERS B-264 VIDEOS REFERENCES HISTORY In hopes to fix the quattro’s handling woes, the Audi engineers proposed to shorten its wheelbase by 320 mm In theory, doing this should greatly enhance turn-in capabilities and also reducing weight in the process which meant overall better performance. The project was approved and the quattro underwent a major overhaul to make it a more capable rally car. Shortening the wheelbase on a car who’s engine sits over or forward of the front axle actually worsens weight bias towards a front heavy vehicle. This was proven when the press got their hands on its first Sport quattro homologation model it tipped the scales at over the front axle the old quattro had 60%. However, the wheelbase being very short makes for a quicker turn-in and greatly reduces rear stability which, in the Sport quattro’s case, could offset its understeer issue if driven properly. This was no easy task as the drivers had to push harder and aggressively “flog” the car through the corners for this to take effect. It was reported that the car still suffered from terminal understeer in low speed corners and/or if driven too cautiously. As such, there was only one good way to drive the Sport Quattro S1 all out and constantly sideways. The drivers had also complained of glare in the windshield of the original quattro so the engineers took the opportunity of the car’s redesign to address the problem with a very original solution since the chassis had to be cut in half to shorten the wheelbase, they married the rear section of the quattro with the front section of the Typ-81 Audi 80/4000 which had the windshield already set at a steeper angle, thus eliminating the glare effect. The new Sport quattro S1 also featured an upgraded all aluminium 20V turbo engine capable of easily producing 450 BHP. However, it was also more “peaky”, making the most of its horsepower in the very high RPM range, which made it ever more difficult to drive on top of its already twitchy handling. This led Audi Sport to develop a closer ratio 6-speed transmission then later the Porsche derived “PDK” unit to help keep revs high and shifts quick. This could provide substantial cumulative time savings over the course of rally stage where shifts are very frequent. Some questionable decisions were taken with the S1 one of which was the replacement of the lower air dam with a large angled sump guard. It is evident that this much harmed aerodynamics. Even though it was much more powerful and technically advanced than the previous car, the Sport quattro S1 was generally not well received by the Audi drivers; Michèle Mouton and Stig Blomqvist in particular had trouble adapting to the new shorter quattro’s features which demanded a driving style not quite compatible with their own. In fact, Blomqvist would shun the S1 while he and Hannu Mikkola raked up points with the “long wheelbase” quattro A2 in the WRC. Blomqvist would win the 1984 driver championship with Mikkola finishing second, easily ahead of their competitors. That year, Audi would get the manufacturer championship back from Lancia. However, for Audi, even though the A2 netted them more consistent results, it was decided to exclusively field the Sport quattro from 1985 and on. E2 UPGRADE In early 1985, Peugeot continued its domination with the 205 Turbo 16 while the more powerful Audi Sport quattro S1 still struggled to match pace. Much more improvements were evidently needed if Audi had any hopes of winning at all. In but a few months time, Audi Sport developed the second evolution of the Sport quattro with striking aerodynamic enhancements. It was the first time that rally engineers created a bodywork package aimed directly at gaining more traction with various spoilers and appendages, as opposed to just gaining stability. In doing so, Audi had created an iconic rally machine that instantly came to symbolise the very image of Group B in most people’s minds; the immortal E2. This all wasn’t just for show as it is estimated that the aero package was able to generate up to 1,100 lbs 500 kg of downforce at high speeds. Much work was done in conjunction to help the weight distribution of the car as everything that could be moved in the trunk/boot area was relocated there; engine coolant radiator, oil cooler, transmission cooler, and even the alternator which was now driven by a small pump motor. The result yielded weight bias up to F51/R49% depending on the setup used. This procedure also much uncluttered the engine bay which allowed for quicker access to key mechanical components. The engineers at Ingolstadt did not rest there as the 5-cylinder turbo aluminium engine was improved yet again. Much of the work was concentrated in making more torque in the mid-range with the possibility of even more horsepower as well as much as 590 BHP was reportedly used in that year’s Finland event. The centre differential was also “liberated” from its constant 50/50 ratio split with the use of a Torsen unit with a Ferguson Formula FFD viscous coupling. This finally allowed a variable torque split between the front and rear axles and much aided the car’s handling. All the improvements of Audi Sport’s new beast were clearly seen in the year’s 1000 Lakes rally in Finland as the car had much smoother transitions in the corners and had an “urgency” to come back down over jumps. The E2 in the hand of Blomqvist set no less than 16 fastest stages times, ultimately finishing in 2nd place only 48 seconds behind event winner Salonen’s 205 T16. Rally ace Walter Röhrl, who played an important role in the Sport quattro E2’s testing and development, describes it as one of the most intense machines he ever got to drive “With this car, you have to think two corners ahead […] finding the correct balance between a decent pace and outright speed was a big challenge.”, he fondly recalls. Röhrl, unlike some of his teammates, was more than willing to adapt his driving to the car’s indomitable demands, and gave the E2 its only WRC win at the 1985 Sanremo rally. This amazing effort has since been immortalised in a well known animated gif In contrast, Stig Blomqvist still didn’t like where Audi was going with the car and, before the end of the season, he had already signed up with Peugeot for 1986. That move infamously led Audi to put him on the sidelines for the rest of the 1985 WRC season. Blomqvist stated years later that his perfect Group B car would have been a “long wheelbase” A2 quattro but with the E2’s very much improved and brutal mechanical components. Sadly, Audi’s efforts at keeping the quattro a contender for the titles was to be in vain as the Peugeot 205 T16 still largely dominated 1985. This lack of success prompted some questionable decisions within Audi Sport, then led by Roland Gumpert, as they were accused of cheating in the year’s Ivory Coast rally by allegedly switching Michèle Mouton’s badly damaged S1 with a chase car. Some insiders saw this as an act of desperation by Audi to keep the quattro competitive at all costs. Albeit it was never proven, Gumpert lost his position within the company soon afterwards. To make matters worse, Lancia unleashed the infamous Delta S4 at the end of the season which immediately brought the Italian team successive victories. For 1986, Ford was on its way with the RS200 and the level of competition would show no sign of letting down. Even though Audi was planning a rumoured 1,000 BHP version of the Sport quattro, all rally insiders agree that no amount of extra horsepower in such a car would have made Audi get its domination back. Ultimately, the Sport quattro E2 would participate in only six WRC rallies before Audi decided to pull out of Group B rallying due to the spectator deaths at the 1986 Portugal event. For Audi’s top management, this unfortunate accident gave them a perfect way out of an unsavoury future in the WRC while somewhat saving face at the same time. Audi Sport quattro S1 / E2 Although Audi would never admit it publicly, the quattro was a road car that was capable in rallying only due to its initial four-wheel drive traction and power advantage. However, unlike the Peugeot 205 T16 and Lancia Delta S4, the quattro obviously wasn’t a purpose built rally car designed from scratch. The Sport quattro was a somewhat desperate attempt from the engineers to push the platform beyond its natural capabilities. Audi Sport knew this and had secretly started developing a mid-engine “silhouette” version of the quattro. When Audi’s top management found out, they killed the special project because they thought that would have meant that their current road going quattro was not up to the task of winning rallies in the public’s point of view. This arguably was what truly made Gumpert lose his position with the company. Audi later contended that Peugeot and the others “cheated” the spirit of homologation by building specialised rally cars from scratch rather than using a standard road going model as its base. Basically, call it German pride. However, this does not diminish the importance that the quattro played in shaping the automotive & rallying world. The fact that it stayed competitive for so long is a testament to Audi’s motto “Vorsprung durch Technik” advancement through technology. Everyone will forever fondly remember the quattro’s exploits and the unmatched spectacle of the Sport quattro E2. It may ultimately not have been the fastest around a rally stage but it was certainly the most exciting rally car to see and hear. Group B’s legendary status would be much less known and appreciated today if not for this car. The rally quattro’s story did not end there as Audi also built a special version of the car based on the E2’s aerodynamics specifically for the 1987 Pikes Peak hill climb event a gambit to try and make the quattro a winner one final time in the dirt.

It was Audi’s gambit at turning the quattro into a competitive Group B car which resulted in an amazing homologation special. It sported a much shorter wheelbase than the normal quattro plus using the steeper 80/4000 model windshield. Its turbocharged five cylinder behemoth was tuned to produce a hefty 302 BHP in street trim which officially makes it the most powerful of all the four-wheel drive Group B homologation road cars that actually competed in the WRC all other rally specials were closer to the 200 BHP mark in street trim. At the time of its production, the Sport quattro was the most expensive Audi model in the dealerships by a very large margin costing around 200,000 German Marks. Yet, it was reported that the car was a handful to drive fast and suffered from terminal understeer due to a nose heavy weight distribution American rally driver John Buffum, even though he was very familiar with the quattro & Sport quattro, infamously crashed one in a Road & Track special feature. It is note to mention that the official designation of the homologation model is the “Sport quattro”, while the “S1” actually refers to the rally evolution model itself.

Sommaire Il y a quelques mois, Audi Sport avait annoncé un partenariat avec Ken Block. Le héros américain de Gymkhana devait promouvoir les modèles électriques de la marque allemande, mais on ne savait pas trop comment. Jusqu’à présent, où Ingolstadt a mis cette Audi S1 e-Tron Concept sous les projecteurs. Le nom fait directement référence à la version rallye de l’Audi Sport Quattro, l’un des héros de la folle époque du Groupe B. L’Audi S1 e-Tron Concept a été développée comme une version moderne de la machine E2 qui a remporté la course de côte de Pikes Peak trois fois de suite. En 1985 avec Michèle Mouton, en 1986 avec Bobby Unser et en 1987 avec Walter Röhrl. Electrikhana Cette Audi S1 e-Tron Concept partage, avec la gagnante de Pikes Peak, ses formes de carrosserie musclées et optimisées sur le plan aérodynamique, en grande partie construites en fibre de carbone. N’étant plus un cinq-cylindres cracheur de feu, l’Audi S1 e-Tron Concept s’appuie sur un système de propulsion électrique qui met en action deux moteurs électriques, mais les spécifications ou les performances sont inconnues. On peut aisément imaginer qu’il y aura beaucoup de puissance, car la machine rebaptisée Hoonitron par Ken Block sera bientôt la grande vedette d’une nouvelle vidéo de drift l’Electrikhana ». Car c’était bien sûr l’objectif principal de la collaboration entre Audi Sport et Ken Block...
