Dieselul bate benzina – aceasta ar fi concluzia pe care pasionatii de automobile ar putea ajunge cat de curand daca nu au fost convinsi inca de superioritatea motorului diesel.
Audi a prezentat prototipul R15+, un model propulsat de un motor diesel conceput sa faca fata cerintelor pe care le impune cursa de 24 de ore de la Le Mans. Echipa Audi Design a vopsit exteriorul acestuia in nuante de rosu si negru carbon, dorind sa marcheze in acest fel inovatiile pe care compania germana le-a adus in acesta competitie.
Audi R15 TDI isi va face debutul, pentru inceput, in cursa de 8 ore de la Le Castellet, ce se va desfasura in data de 11 aprilie, un alt test pana la startul Le Mans (Franta) va fi in cursa de 1000 de kilometri de la Spa-Francorchamps (Belgia). Motorul diesel, cu 10 cilindri in V, cu capacitate de 5.5 litri genereaza 440KW (572 cai putere) la turatia maxima, consumul de motorina fiind mult mai redus decat in cazul unei unitati pe benzina de aceiasi putere. Echipa germana a optat pentru o baterie usoara, de tip litiu-ion, pentru a alimenta echipamentele auxiliare. Cuplul motor de 1050Nm este transmis rotilor cu ajutorul unei cutii de viteze cu sase rapoarte.
Progressive design for the Audi R15 TDI
# Diesel race sports car with a fresh outfit
# Audi design team demonstrates “pleasure in efficiency”
# Test in racing conditions at Le Castellet
Ingolstadt, April 5, 2010 – Audi wants to surprise the spectators at this year’s 24-hour race at Le Mans (France) with a progressive design: the Audi Design Team created a fresh outfit for the innovative diesel race sports car that bears all the hallmarks of “pleasure in efficiency.”
Whereas silver was the dominant color of the Audi R15 TDI last year, the 2010 model boasts a radical new design that features more red. In addition, large areas of the Le Mans race sports car that is internally designated as “R15 plus” will be kept in a purist black carbon-fiber look.
“We’re happy that we were allowed to give the car such a progressive look,” say Markus Auerbach and Tobias Drews from the Audi Design Team. “We wanted to add a dash of surprise when the Audi leaves the pits at Le Mans. We practically opened up the bodywork and are exposing the light-weight construction and its uncompromising technical development – and with a little rock ‘n’ roll for good measure.”
The Audi R15 TDI sporting its new design will make its debut at the Le Castellet 8 Hours on April 11. Audi Sport Team Joest will contest the 2010 season opener of the Le Mans Series in preparation for the Le Mans (France) 24 Hours on June 12/13. Another test race is planned at the 1000-kilometer race at Spa-Francorchamps (Belgium).
“The race at Le Castellet comes at a very early point in time for us and is nothing but a test in racing conditions,” stresses Ralf Jüttner, Technical Director of Audi Sport Team Joest. “Even though it’s a difficult logistical undertaking, we wanted to gather experiences with the R15 plus at a race as early as possible. Le Castellet offers the opportunity to do this.”
The 2010 version of the Audi R15 TDI completed a roll-out at the Audi test track in Neustadt at the beginning of March. The prototype was subsequently flown to the USA for initial tests which primarily featured aerodynamics trials. A five-day endurance test followed at Sebring (Florida) at which about 5 500 kilometers were reeled off without any technical problems worth mentioning.
In Europe, the final set-up work with a view toward Le Mans is on the agenda. Further track tests will now be followed by the first run in a race at which the result will be of secondary importance for Audi though. “Le Castellet will strictly be about gathering additional experience with the R15 plus,” emphasizes Head of Audi Motorsport Dr. Wolfgang Ullrich. “Racing conditions simply can’t be simulated in normal track tests; that’s why we’re contesting a race at such an early stage.”
It is planned to field the R15 plus with chassis number 202. Audi Sport Team Joest has nominated Dindo Capello (Italy), Tom Kristensen (Denmark) and Allan McNish (Scotland) as drivers. “However, we will only decide whether all three drivers will actually race at short notice,” says Dr. Wolfgang Ullrich.
Since Audi has performed several endurance tests for the Le Mans 24 Hours at Le Castellet in recent years, the team and drivers are intimately familiar with the circuit in southern France.
Audi, by the way, has very good memories of its most recent racing commitment at Le Castellet: in 1995, Frank Biela won the Touring Car World Cup there in the Audi A4 quattro against strong rivals.
