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.

Audi TT Ultra Quattro Concept throws lightness at the problem

Audi is celebrating the 2013 Wörthersee Tour with a special concept version of the company's TT. The Audi TT Ultra Quattro concept tips the scales at just 2,449 pounds thanks to some extensive engineering work. The company pulled nearly 95 lbs from the car's body structure and used carbon-fiber reinforced plastics for many of its detachable body components. As a result, the concept weighs in at a full 220 pounds lighter than its production counterpart. Throw in a wicked turbocharged 2.0-liter four-cylinder engine with 310 horsepower and 295 pound-feet of torque, and you get a machine with the power to weight ratio in the supercar realm. 0-60 comes up in 4.2 seconds and top speed is listed at 173 mph.
Inside, the TT Ultra Quattro features plenty of carbon fiber trim, and designers also fitted the seats from the R8 GT to save a little weight. The buckets use CFRP for the seat frames, saving nearly 50 pounds in the process. In a world where automakers seem blind to the negative effect of throwing more heft at a vehicle, we're in love with the Ultra Quattro concept.
