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.

2016 Audi A3 Sportback headed to US under diesel power [w/video]

Every get the feeling that automakers aren't really listening to what it is that you want in an automobile? Well, Audi is. Following what it calls "an outpouring of enthusiasts' support," the German automaker has announced that it is bringing the new, 2016 A3 Sportback to the US under diesel power, in the summer of 2015.
Unveiled today at the New York Auto Show, the new A3 TDI Sportback joins an expanding range of A3 models available Stateside. Whereas the Sportback hatch was until now only slated to be offered in E-Tron hybrid form, and the TDI only as a sedan, this model combines the bodystyle of the former with the power of the latter. The new TDI slots into the family alongside the gasoline-powered A3 and S3 sedans and A3 Cabriolet as well.
Power comes from a 2.0-liter turbodiesel four with 150 horsepower and mated to a six-speed S tronic transmission. Because it's still a year away from launch, Audi tells us it hasn't determined figures for performance, fuel economy or carbon emissions numbers, but when it joins the company's considerable diesel offerings (which already include the A6, A7, A8, Q5 and Q7) as part of the new A3 rollout over the course of the next 18 months, you can bet it'll provide that combination of low-end grunt and long-range capability that diesel enthusiasts crave. In the meantime you can scope out the details and b-roll footage below for a closer look.

VW recalls 220,000 Atlases, Atlas Cross Sports for airbag defect [Updated]

[Update: Audi of America has confirmed that no U.S. models are among the recall population for plug-in hybrid fire issue.] Volkswagen has issued yet another recall for its Atlas SUV, this time for side airbags that may not deploy correctly in an accident due to a problematic connection in one of the vehicle's wiring harnesses. The campaign covers 222,892 Atlas and Atlas Cross Sport models built for the 2019-2023 model years.  The issue stems from a connection with the wiring harness that runs from the A-pillar into the door. VW says that harnesses produced by one of its suppliers were not built with additional measures to prevent movement at the connection point. Small movements can cause abrasion of the metal contacts which could lead to a whole host of electronic misadventures, including the potential for airbag deployment to be delayed in a crash.  "Micro-movement of the wire harness (terminal A-Pillar to front door) can result in damage to the wire terminal surface. Damage to the surface can [result] in fretting corrosion which may cause sporadic interruption in the electrical connection to the components of the front door," VW said in its defect notice. "The airbag warning light may illuminate if a malfunction is detected. Other symptoms of a sporadic interruption of the affected electrical connection can be: inadvertent rolling down windows, inadvertent park brake engagement at low speeds (below approx. 3km/h or 1.8mph), warning regarding faulty door sensor," VW said.  Not every model built within the range defined above is subject to the recall; terminals from other suppliers were manufactured with the necessary safeguards in place. If you own a 2019-2023 Atlas or Atlas Cross Sport, keep your eyes peeled for a notification from VW regarding the campaign, likely some time in early-mid May.  PHEV problems Across the Atlantic, the VW Group mothership confirmed that it will recall more than 100,000 plug-in hybrid models worldwide to address a fire risk. The recall was launched in response to 16 reported incidents of fires stemming from insufficient insulation of the PHEV battery pack that allows the engine cover to make contact if it is not completely secure. If that happens, the heat from the battery can ignite the engine cover. The recall will cover PHEVs build by VW, Audi, Seat and Skoda, Reuters reports, including the VW Passat, Golf, Tiguan and Arteon — plug-in variants of which are not sold in the United States.
