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.

Refreshed 2015 Audi A8 starts at $77,400*

Audi definitely made the US wait for the refreshed 2015 A8 and S8. The updated models were first unveiled last summer, but it has taken until June for the revised flagship sedan to reach dealers here.
The refreshed A8 line doesn't come cheap, though. Prices are up $2,000 or more over the 2014 model year. The basic 3.0T model goes for $77,400 or $81,400 for the long wheelbase version. The long wheelbase TDI is $85,100. The standard 4.0T model asks $86,400 or $90,400 for the longer one. An S8 sets back buyers $114,900, and the full bore A8L W12 is $137,900. All of these prices exclude destination (which was $895 last year and now stands at $925, according to Audi representative Mark Dahncke).
To make the wait worth it, Audi is packing the sedan with new technology and given it the slightest restyle. All models of the luxurious vehicle now come standard with full LED headlights. The 2015 model also benefits from electromechanical steering, available variable ratio steering and active lane assist. The night vision system is also updated to detect animals and alert the driver. Mechanically, there are some tiny tweaks as well. The 4.0T V8 is boosted to 435 horsepower, compared to 420 hp previously, and the 6.3-liter W12 now has cylinder deactivation.

Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.
