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.

We demo Audi's Traffic Jam Assistant tech on the road [w/video]

The closer automotive technology comes to making good on the promise of fully driverless vehicles, the better we see just what difficult work reaching that ultimate goal will become. That's because, unlike so many other in-car technologies that need only integration into a vehicle, truly autonomous cars will also insist on involvement with the surrounding environment, fellow motorists, infrastructure in cities and other communities and making it all work without exposing automakers to law-breaking or tremendous possible litigation. Clearly that isn't all about to happen in one go.
At CES in 2012, Audi told us about a debuting technology that would mark a significant step along the path towards self-driving cars: Traffic Jam Assistant. This year, the German automaker invited us out to Las Vegas to see the jam-busting technology in action, on a relatively busy freeway.
The Traffic Jam Assistant (we're pretty sure that name is still in Beta) promises to relieve drivers from the tedium of slow-moving freeways by taking care of braking, acceleration and staying inside of the lane - all with no input from the human behind the wheel. While still a fair step from truly autonomous driving, the goal here is to give a commuter some respite from the mechanical, time-wasting traffic jam paradigm, potentially opening up a space for productivity in the process. (Audi can't come right out and say that TJA will allow you to use your cell phone in traffic, as that's still against the law in many places, but something like that is clearly on the radar... er... LiDAR.)

Volkswagen Group recalls 281,505 VWs and Audis for fuel leaks

The Basics: Volkswagen Group is recalling 281,505 total Volkswagen and Audi brand products in the United States for potential fuel leaks. Certain versions of the Audi A3, A6, A7, Q5, and Q7 are affected. In addition, some versions of the Volkswagen Golf, Golf SportWagen, and Golf GTI fall under the recall. It's unclear if vehicles outside of the United States will be recalled as well. The Problem: There are actually three separate recalls for three separate issues that all pertain to leaky fuel. All three recalls were issued simultaneously. The risk of unintended ignition is the main concern here. First off, 2012-2013 Audi A6 and Audi A7 models [28,249 cars] are being recalled because of a degrading fuel hose in the engine compartment. Secondly, 143,214 gas-powered 2009-2012 Audi Q5s and 2007-2012 Audi Q7s are being recalled. The fuel cap may crack on these vehicles, leaking fuel. Finally, 110,042 total units of the 2015-2016 Volkswagen Golf, Golf SportWagen, GTI, Audi A3 sedan, and A3 Cabriolet will be recalled because of fuel leaking from the evaporative emissions system. Injuries/Deaths: According to Reuters, Volkswagen has reported no injuries or deaths related to the fuel leaks. In addition, the company has said there have been no fires started due to the leaks. The Fix: Three separate issues means three separate fixes. Volkswagen and Audi will be reaching out to customers soon, though the parts aren't yet available. For the A6 and A7, Audi will simply replace the under hood hose. For the Q5 and Q7, dealers will clean the pump flange and install a butyl rubber band to protect the pump. Finally, the affected Golf and A3 models will have the suction cup in the emissions system replaced. If you own one: Volkswagen and Audi will begin contacting owners starting next month regarding a fix. Related Video: News Source: NHTSA, Reuters Recalls Audi Volkswagen
