The Audi R15 TDI, commonly abbreviated to the R15, is a Le Mans Prototype (LMP) racing car constructed by the German car manufacturer Audi AG. It is the successor to the Audi R10 TDI.

Like its predecessor, the R15 TDI uses a turbocharged diesel engine, although the R15's V10 engine is physically smaller than the R10's V12. The smaller engine is pushed further toward the middle of the car than in the R10, resulting in a more neutral weight balance that gives the car better agility around the corners than its predecessor.[1]

History

2009

The car was tested for the first time in December 2008, before its official unveiling and competition debut at the 2009 12 Hours of Sebring race, 21 March 2009. Three R15 TDIs participated in the 24 Hours of Le Mans in June 2009, under the control of Joest Racing. Audi did not defend their American Le Mans Series, or Le Mans Series titles with the R15 TDI.

The R15 made its competition debut at the 2009 12 Hours of Sebring in March 2009, and followed this event at the 24 Hours of Le Mans in June.[2] The R15 got off to a perfect start by winning the 12 Hours of Sebring, setting a new race record in the process, but then lost in its second entry.[3] Peugeot, its rival, with its 908 HDi FAP, took the top two spots in the 24-hour race, ending Audi's five-win streak that lasted back to 2004 with the gasoline-powered R8.

The R15 TDI features a 5.5 litres (336 cu in)[4] Turbocharged Direct Injection (TDI) turbodiesel V10 engine, rated at over 600 PS (440 kW; 590 bhp) and 1,050 newton metres (774 lbf·ft) torque. The electrical system uses a lithium-ion battery, a first for Audi sports prototypes, as well as LED headlights,[5][6] and a unique system of LED rear lights that are mounted on the rear wing endplate.[7]

In the week running up to the 2009 24 Hours of Le Mans, rivals Peugeot lodged a protest against the R15, claiming that its bodywork did not comply with regulations stating that parts of the bodywork cannot be fitted with the sole purpose of generating downforce. However, after the Wednesday free practice session, the ACO rejected Peugeot's protest.[8] At the 2009 Le Mans, Audi was unable to continue its winning streak that dated back to 2004. The No. 3 R15 ran off at Indianapolis corner, and the No. 2, driven by Luhr, crashed and retired. In the evening, the No. 1 Audi lost a lap to the leading Peugeot which was faster, and further technical issues dropped it a full 7 laps down the order. The sole surviving Audi clinched a podium finish, finishing in third place.

Audi announced on 25 August 2009 that two R15s would race at the 2009 Petit Le Mans. Both Audis led for approximately 90% of the race but a late spin during the final rain-soaked caution handed the victory to one of the Peugeot 908 HDi FAPs entered by Team Peugeot Total. This loss was Audi's first since competing in Petit Le Mans since their initial attempt at Road Atlanta back in 2000.

R15 TDI Plus (2010)

In response to losing the 24 Hours of Le Mans and the Petit Le Mans to the Peugeot 908s, Audi updated their R15 for the 2010 season, creating the R15 plus. 2010 Regulations reduced the size of diesel LMP1 air restrictors and turbocharger boost pressure. However, despite this, Audi's engineering team led by Ulrich Baretzky were able to achieve engine power and performance that was comparable to the 2009 powerplant. Aerodynamic efficiency was also a major area of focus for 2010. The frontal area of the car was redesigned to reveal the raw crash structures. The front fenders were also lowered in an effort to reduce drag while the concept of air running through the car was abandoned for a more conventional design. The air channel that exited to the side of the car was redesigned resulting in a more conventional configuration, and a new headlight concept was introduced. Audi stated that they had improved the fuel tank and cooling system as well.

Racing history

At the 2010 24 Hours of Le Mans, the three Joest Racing-entered R15s finished on the podium.

The new vehicle was a success at the 2010 8 Hours of Le Castellet, winning five laps ahead of the next competitor Aston Martin. The Oreca Peugeot, which was supposedly its rival, dropped a full eight laps down the order because the airjacks failed to come off. Audi continue to go flat out and in the end finished ten laps ahead of the Peugeot. Audi had now been able to achieve both the speed and reliability combination that they considered sufficient to match the Peugeot challenge for Le Mans. A full squad of three cars was entered for the next race which was the 2010 Spa 1000 km, finishing third (#7, behind the two Peugeots – No. 3 took first, No. 2 took second), fifthth (#9) and twelfth (#8) respectively. Audi treated the race as a setup exercise for car configuration at Spa that would then be used for the 2010 24 Hours of Le Mans.

The 2010 24 Hours of Le Mans race got off to a tightly contested start with Peugeot occupying the top spots (as they did for qualifying) and for a large part of the race. However, it was apparent throughout the race that Audi were unable to match the pace with the Peugeots, but were working according to a different race strategy. By pushing the French manufacturer to the limit, three of the Peugeot cars experienced engine problems due to connecting rod failure towards the latter part of the race. With engine troubles for three of the Peugeots that forced the cars to retire before the end of the race, and an early exit by the No. 3 due to a suspension failure, the three Audis would finish 1–2–3 (the No. 9 took first, No. 8 took second and No. 7 took third), with all cars exceeding the previous distance record of 5,335.313 km (3,315.210 mi) set in the 1971 race by Dr Helmut Marko and Gijs Van Lennep: the winning No. 9 car, led by Mike Rockenfeller and two Porsche factory drivers Timo Bernhard and Romain Dumas, set not only a record-tying number of laps around Le Mans of 397 laps, but eclipsed the distance record outright at a distance of 5,410.7 km (3,362.1 mi).

Audi R15 at Sebring 2011

Post-Le Mans Audi did not collect any more victories and lost all three remaining races to the Peugeot 908, which happened to be part of the ILMC championship. Audi fielded two cars into the Silverstone 1000 km but the No. 7 crashed and retired. The sole remaining No. 8 finished third. At Petit Le Mans two cars were entered but both lost to a Peugeot 1–2 victory. At the R15's last race, teo cars were entered into the Zhuhai 1000 km. Both cars were leading the 908s by thirty seconds after Sebastian Bourdais make contact with a GT2 Porsche. A late safety car session saw the Audi's lead shrink to thirteen seconds. Afterwards a controversial team-work by Peugeot saw the No. 1 908 slowed down the No. 7 Audi enough to let the No. two Peugeot come out of the pits just two seconds ahead. The race ended with Peugeot No. 2 winning four seconds ahead of the Audi. Audi did not win the LMP1 Le Mans Series team championship nor the ILMC LMP1 championship.

The R15's final race was at the 2011 Sebring 12 Hours. Both cars ran in 2010 configuration with new restrictors. The No. 1 Audi finished fifth overall after two consecutive tyre punctures and rear bodywork damage in the hands of Mike Rockenfeller. Later in the race the No. 1 had to serve a penalty for speeding in pitlane. The No. 2 ran at the front exchanging the lead with Peugeot until a shunt by one of the Peugeots at turn 17 put Capello out of contention with a suspension failure. The No. 2 finished fourth overall, albeit five laps down from the winning Oreca Peugeot. Throughout its career the R15 won three of the ten races it entered; Sebring in 2009, Paul Ricard and Le Mans in 2010.

Replacement

Main article: Audi R18

With a change in Le Mans Prototype engine regulations planned for 2011 Audi is working on a successor to the R15 TDI, known as the R18.[9] In interview with Autosport Magazine, the head of Audi's Motorsport programme Doctor Wolfgang Ullrich stated that the R18 will be a closed roof coupe similar to the 908, however Ullrich did not state the car would be a hybrid or what fuel it will be running on. What he did state however is that one of the advantages of an open-top prototype has been lost with the recent regulation changes: open-top prototypes often shorten pit times compared to closed coupes; however with pit times slowed down due to new rules requiring only one man with one airgun in the pits, the advantage has been negated. The R18 would be Audi's first-ever coupe since the failed Audi R8C in 1999; the Bentley Speed 8 (which won in 2003 with Audi-developed engines) were also closed prototypes. Along with the Peugeot 908 HDi FAP (replaced with a new generation 908), the R15 TDI will be replaced; however, due to developmental reasons, the R15 TDI made its final run at the 2011 12 Hours of Sebring under the R15++ configuration, where contact with other cars took them out of contention.

Audi is intensively preparing for the 2012 sports prototype season. A test team has started the next trial phase of the LMP1 sports car for the 2012 season in the United States this week.

  • Tests at Sebring (U.S. state of Florida)
  • Allan McNish plus five other Le Mans winners at the wheel
  • Preparation for 2012 season

After the previous tests of the further development of this year’s Le Mans winning car took place behind closed doors, Audi is now going into public at a race track for the first time. Today (17 Dec), Audi Sport runs tests with two vehicles at the Sebring (Florida) circuit. The second LMP1 sports car serves to compare the test results. Taking turns at the wheel of the two development vehicles are the 2011 Le Mans winners, the Swiss Marcel Fässler, the German André Lotterer and the Frenchman Benoît Tréluyer. Also involved in the tests are Dindo Capello, Tom Kristensen and Allan McNish, who were last victorious at Le Mans in 2008. The tradition-steeped American circuit has a special significance for Audi, not only because Audi has celebrated nine victories at the Sebring 12 Hours since the 2000 season. The 5.95-kilometre track that features 17 highly different types of turns offers plenty of variety, which makes for excellent test conditions. The rough concrete of the former airfield’s take-off and landing strip in combination with the tarmac of the other track sectors puts the material to a particularly tough test. On March 17th, the 12-hour race will open the new FIA World Endurance Championship (WEC) as well as the American Le Mans Series (ALMS) at this venue.

While the component tests have already started, Audi will not announce the details of the 2012 racing program, the driver line-up and the technical state of the development until a later date.

Гоночный болид Audi R18 e-tron quattro LMP1 2014 года – самый сложный

Гоночный болид Audi R18 e-tron quattro LMP1 2014 года рассматривается как самый передовой и сложный автомобиль, созданный компанией Audi. Новая модель стремится улучшить свое предыдущее воплощение, которое стало победителем гонки в Ле Ман.

Новые инновации

LMP1 Racecar отличается целым рядом блестящих инноваций. Двигатель V6 TDI с центральным расположением был усовершенствован таким образом, что он предлагает улучшенную мощность и производительность.

Передняя ось была интегрирована с электронной гибридной системой e-tron Quattro, что позволяет сохранять кинетическую энергию, которую можно использовать в случае необходимости. Блестящая новая гибридная система была оснащена электрическим турбонагнетателем, позволяющим двигателю внутреннего сгорания хранить энергию, преобразованную из тепла.

Среди преимуществ от внедрения этих улучшений можно отметить, что эта модель использует на 30% меньше топлива.

Аэродинамика

Кузов стал тоньше, чем в более ранних версиях, и это позволяет R18 передвигаться гораздо более аэродинамически обоснованным образом. Колеса помогают сократить сопротивление. При меньшем сопротивлении автомобиль может практическим лететь по гоночной трассе.

Форма передних колес также был изменена для дальнейшего повышения уровня аэродинамики.

Улучшения в области безопасности

Инженеры Audi извлекли уроки прошлого и улучшили элементы безопасности этой модели, структура кабины также была улучшена, как и возможности видимости для водителя.

Монокок был отделан тканью. Вес стал немного больше, и это также может уменьшить повреждения в результате несчастного случая.

В целом, Audi R18 e-tron quattro LMP1 Racecar 2014 года является одной из самых впечатляющих моделей, выпущенных этим производителем.

Audi представила новый R18 LMP1

Audi подвела итоги завершенного автоспортивного сезона в Мюнхене. Однако, в основном все, что происходило, касалось больше сезона будущего. Было объявлено, что в чемпионате GT примет участие новый Audi R8 LMS. И проведет в первенстве мира весь сезон.

Уже подтверждено, что доктор Вальтер Ульрих продлил свой контракт и останется руководителем спортивного отделения марки до конца 2017 года. В этой связи был подтвержден и состав пилотов в кузовной серии DTM. Здесь пока никаких перемен не произошло.

Состав пилотов, стартовавших в кузовном чемпионат DTM за Audi, сохранен полностью

Несколько слов было сказано о Кубке Audi Sport TT будущего года. Здесь организаторы столкнулись с серьезными трудностями. На 20 вакантных мест поступили заявки от 125 пилотов. Но самым главным событием торжеств стала мировая премьера нового главного оружия Audi.

Вальтер Ульрих представил новый Audi R18 LMP1, автомобиль, который в будущем году выступит в 24-часах Ле-Мана и в чемпионате мира на выносливость WEC. Два последних года Audi не удавалось выиграть чемпионат мира среди марок. А прошедшем сезоне все призы ушли главному теперь сопернику «Четырех колец» – команде Porsche.

Доктор Вальтер Ульхир остается у руля гоночного отделения Audi до конца 2017 года

Естественно Audi жаждет реванша.

Итак, новая техника. Пока только внешний вид и общие фразы. Полностью пересмотрена аэродинамика, проведена ревизия каждого узла и агрегата и по ее результатам конструкция очень серьезно облегчена. Модифицирована гибридная система, применены новые литий-ионные батареи и модернизирован двигатель TDI.

Было объявлено, что Audi и Porsche продолжат честную борьбу на трассе. Никаких корпоративных приказов не будет. Команды-соперницы договорились, что в будущем сезоне каждая из них будет выступать во всем чемпионате мира только двумя экипажами.

Особенно подчеркивалось, что по две машины будут стартовать и в Ле-Мане. Заводским коллективом Audi станет команда Audi Sport Team Joest, которая и выведет новую Audi R18 LMP1 на первый этап чемпионата мира в британском Сильверстоуне 17 апреля будущего года. А о технических характеристиках новой гоночной техники будет заявлено, скорее всего, в преддверии межсезонных тестов.
