Audi fires head of R&D, Wolfgang D"urheimer

According to Car and Driver, citing a report in Germany's Der Spiegel magazine, Audi has fired Wolfgang Dürheimer, the brand's head of research and development.
Dürheimer had originally signed on as Audi's R&D boss in September 2012. Prior to that, he had served as the head for both Bentley and Bugatti, and was formerly the development chief at Porsche (where he is credited with helping get the original Cayenne into production, a move that ushered a new era of profitability for the company). Dürheimer moved to Audi following a management shakeup within the Volkswagen Group in mid-2012.
During his time at Bentley, Dürheimer spearheaded the brand's efforts to launch an SUV. But at Audi, he reportedly quickly put a stop to costly projects such as the R8 E-Tron and the rotary range-extender engine for the A1 E-Tron. Furthermore, Car and Driver reports that Dürheimer shuffled the reporting structure within the brand's design department, and that VW Group CEO Martin Winterkorn had apparently disagreed with him several times on the styling direction for the brand.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

Audi follows suit with TDI stop-sale

Yesterday, Porsche issued a stop-sale on its Cayenne Diesel, following the news that the Volkswagen Group's 3.0-liter diesel V6 is also fitted with cheating software. Now, according to Automotive News, Audi is issuing a similar stop-sale in the US, but in the case of that brand, it affects more than just one model. Audi's stop-sale covers diesel-powered versions of the 2013-2015 Q7, as well as the 2014-2016 A6, A7, A8, and Q5. All of these models can be had with the 3.0-liter TDI V6, which up until this week's news, was not included in Volkswagen's massive diesel scandal. No recall is currently planned, according to Automotive News. Additionally, Volkswagen has yet to issue a stop-sale on its Touareg TDI, which also uses the 3.0-liter V6. The Touareg TDI can still be found on Volkswagen's consumer site, as of this writing.
