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.

Recharge Wrap-up: Tesla seeks Gigafactory architect, Uber hails carpools

Tesla is looking for an architect to help design its proposed Gigafactory battery manufacturing facility. According to the Palo Alto-based job listing, which is titled "Architect - Gigafactory," the applicant must have, among other qualifications, over five years of experience with "high-tech infrastructure and operational facilities (semiconductor, solar, battery, waste water treatment plants, etc.)." The job also includes being away from home quite a bit, as it the listing states, "This full time role requires the flexibility of traveling when needed (up to 70 percent) and doing whatever it takes to achieve project objectives." Think you've got what it takes? See the listing for yourself, here, or read more at Silicon Valley Business Journal. Tesla has appointed Robyn Denholm of Juniper Networks to its board of directors. Denholm is Executive Vice President, Chief Financial and Operations Officer at Juniper Networks. Denholm replaces Brad Buss as chair of Tesla's Audit Committee and a member of the company's Compensation and Nominating and Corporate Governance committees. Buss will remain a member of Tesla's board as he joins SolarCity as CFO. Denholm is Tesla's first female director. Read more at Bloomberg, or in the press release below. Uber, the company behind the now famous ride-hailing app, is introducing its carpooling service, UberPool. The service matches drivers with (hopefully multiple) passengers going to similar destinations, with users paying just a fraction of the cost of a normal taxi, or even an Uber ride. If a rider can't get matched with a driver, they can enjoy a discounted Uber ride. As the company points out in its blog, "At these price points, Uber really is cost-competitive with owning a car, which is a game-changer for consumers." UberPool is currently running a private beta program, which it plans to expand on August 15. Read more in-depth about the UberPool at Forbes, or learn more at Uber's blog. For a few reasons why this new expansion might run afoul of archaic laws (put there to keep entrenched interests in play), check out Engadget. Plug-in hybrids are encouraging an evolution of transmission technology. Companies like Schaeffler and ZF Friedrichshafen are adapting their transmissions to include electric motors within them for use in plug-in hybrids. For example, the electric motor in ZF's eight-speed powers the transmission when the internal combustion engine is shut off.

Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.
