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.

Winterkorn kept diesel scandal secret, letter claims

Former Volkswagen Group CEO Martin Winterkorn allegedly kept quiet for two weeks about emissions defeat devices in the company's models. US officials eventually made the automaker's deception public on September 18th. "In the conversation on 03.09.2015 with the regulator CARB (California Air Resources Board), the defeat device was admitted," an employee told Winterkorn on September 4, according to Reuters citing Germany's Bild am Sonntag. Based on this information, Winterkorn had plenty of time to admit the problem. Evidence like this letter continues to suggest top figures knew about the emissions problem. In addition, a separate Bild am Sonntag report recently claimed that an employee emailed Winterkorn in May 2014 to tell him US regulators could discover the cheating. In the lower echelons of the company, the deception was allegedly an open secret among engineers as early as 2006, and people kept quiet even after workers tried to admit what was happening. This culture of secrecy seems to go even deeper than just the diesel emissions scandal. For example, engineers admitted that they cheated on CO2 tests to meet the company's strict standards. According to Green Car Reports, these problems also affected the US. In 2004, an Audi worker in America allegedly discovered an issue with the exhaust gas temperature sensor in some vehicles, but a German executive said not to admit the problem to US regulators. It's not clear whether any high level employees tried to fix the diesel emissions issue or if they simply kept the problem hidden. The company's internal report, which is due in the latter half of April, might address that concern. So far, the VW Group has said only a small group of people caused the scandal. However, these many allegations to the contrary make that claim difficult to believe. Related Video:

VW Group to split brands under four holding companies

The Volkswagen Group is planning a tremendous shift in its internal structure that will decentralize operations by splitting its 12 brands into four different holding companies. Here's the breakdown. Things will be split logically, considering the inter-sharing of parts, platforms, and engines. The Volkswagen brand, Seat, and Skoda make up a passenger vehicle division led by former BMW man Herbert Diess. Audi, which is tightly intertwined with Lamborghini and motorcycle manufacturer Ducati, will be managed by current Audi exec Rupert Stadler. Porsche and Bentley, which are already quite close, will be joined by Bugatti and run by Matthias Mueller. Finally, a commercial vehicles division will include Volkswagen Commercial, Scania, and Man. Former Daimler exec Andreas Renschler will take care of the big vehicles. The massive move, according to Automotive News Europe, is part of an internal VAG effort to move away from the structure established by ousted Chairman Ferdinand Piech, who favored a compact, but highly centralized, management structure to oversee the independent actions of the company's brands. Criticism of Piech's arrangement stemmed from the company's slow responses to changes in the market, ANE reports. The new structure should make for a more efficient, streamlined company that's better able to make crucial decisions. What are your thoughts? Should VAG decentralize, or did Piech have the right idea? Have your say in Comments.
