Audi, McLaren to bring winning cars back to Le Mans

Now gearing up for its 83rd running, the 24 Hours of Le Mans is as much about history as it is about racing forward. So this year, two key outfits in the event's history are celebrating by bringing back the cars with which they dominated in years past. Audi has been a force to be reckoned with and the team to beat at Le Mans in the modern era. It still may not have topped its sister brand and chief rival Porsche's record 16 wins, but Audi's 13 have all come in the past fifteen years since the turn of the millennium. That's one heck of a winning streak, which the German outfit will highlight by bringing every single one of its winning prototypes back to La Sarthe this year. From the R8 that kicked it all off in 2000 through the diesel R10 TDI to the R18 E-Tron Quattro that won last year. Ingolstadt won't be alone in racing down memory lane. McLaren announced it will be bringing back all five F1 GTRs that dominated the race in 1995. The quintet that finished first, third, fourth and thirteenth overall will lead a parade lap around the French circuit, joined by the new P1 GTR that will be making its dynamic debut as well as the customer examples of the special edition 650S Le Mans. What's more, winning drivers from '95 – Yannick Dalmas, Masanori Sekiya and JJ Lehto – will be on hand to participate in the parade lap as well, further highlighting the occasion.

Since 2000, the brand has won the race 13 times. This year, Audi has assembled all of its Le Mans winning models for a group photo for the first time. Every single one of them represents 'Vorsprung durch Technik.' The string of victories began with the Audi R8 in 2000. "Following a year of learning and gathering experience at Le Mans, we started the 2000 season with a completely new design," says Head of Audi Motorsport Dr. Wolfgang Ullrich.

Audi will submit emissions fix for 3.0 TDI V6 to EPA and CARB

Audi will develop a software update for the emissions control system on Volkswagen Group's 3.0 TDI V6 and will submit the changes to the Environmental Protection Agency and California Air Resources Board for approval. If the government regulators accept it, the tweaks could end the emissions problems for an estimated 85,000 of these engines in the US in Audi, Porsche, and VW models. However, the stop-sale still covers these vehicles until further notice. Audi admits in its statement to failing to disclose three "auxiliary emission control devices" on the V6 to regulators, and US law considers one of these systems a defeat device. VW Group offered the engine in the US on the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year. The mill was also available on the VW Touareg and Porsche Cayenne. The EPA filed a violation against the 3.0 TDI on November 2 because the agency reported that the engine's software contained a defeat device to circumvent emissions tests. The regulator recently extended that notice to cover these powerplants in the US from the 2009 to 2016 model years. Audi's statement vaguely estimates the price of this problem to be in the "mid-double-digit millions of euros," and the automaker could face financial punishment by regulators. "Determinations regarding potential penalties and other remedies will be assessed as part of the investigation EPA has opened in conjunction with the US Department of Justice," an EPA spokesperson told Automotive News.

That is the result of the discussions held between a delegation from AUDI AG and the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). The updated software will be installed as soon as it is approved by the authorities. The three brands Audi, Porsche and Volkswagen are affected. Audi estimates that the related expense will be in the mid-double-digit millions of euros.
