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.

Volkswagen may soon have remedy for more cheating diesels

Nearly a half-million motorists who own Volkswagens equipped with 2.0-liter engines have known for a few weeks the company might wind up buying back their vehicles as part of a settlement surrounding the company's emissions cheating. But about 85,000 drivers who own similarly afflicted diesels with 3.0-liter engines have been stuck without a remedy. They may not be waiting much longer. Bloomberg reports that Volkswagen will soon propose a fix for vehicles, including those from Audi and Porsche, equipped with 3.0-liter engines that will include new software and a new catalytic converter for the vehicles. Discussions with federal regulators are ongoing, according to the news outlet. "We are cooperating with the regulatory agencies and working with them on an approved solution," says Audi spokesperson Mark Clothier. "Beyond that, we cannot comment on ongoing investigations." Regulators have alleged that the company's 3.0-liter engines contain "defeat devices," illegal software that allows a vehicle to detect when it's undergoing an emissions test and turn off pollution control during real-world driving. The defeat device allows these vehicles to increase emissions of nitrogen oxide up to nine times the Environmental Protection Agency's allowable threshold. Affected 3.0-liter vehicles include the 2014 Volkswagen Toureg, 2015 Porsche Cayenne and the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5. Volkswagen is slated to finalize its plans for buying back the afflicted 2.0-liter cars and potentially offer those motorists "substantial compensation" for their troubles by June 21, and it's possible that a formal announcement on the 3.0-liter vehicles would come at the same time.

Audi prepping minor refresh for S6

Audi is well underway with testing for all of the refreshed versions of its A6-based sedan. We've already shown you shots of the Euro-spec A6 Allroad (which will wear some of its styling with our US-spec A6 sedan), and now we have some shots of a car that will actually arrive in the United States - the S6.
Like the Allroad, this will be quite a modest refresh, with tweaks to the headlights and taillights, as well as some slightly revised front and rear fascias. The headlights should get a new LED DRL pattern, although we doubt the changes will be much more drastic than that.
As with the Allroad, it seems likely that Audi will make a few very small changes to the interior, while the MMI infotainment system should also see an update. Changes under the hood, though, are more difficult to guess. That said, minor changes could be in store, but don't expect a dramatic increase in power or performance.
