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.

VW will expand goodwill package to larger diesels

Volkswagen Group of America will expand its goodwill package to affected owners of the VW Touareg and other models with the 3.0 TDI. The company may also replace the catalytic converter on some cars equipped with the 2.0-liter four-cylinder TDI engine to bring it into compliance with US emissions. VW Group of America boss Michael Horn told Reuters he plans announce the goodwill program's expansion to the 2009-2016 Touareg during the Detroit Auto Show, and company spokesperson Jeannine Ginivan also confirmed this to Autoblog. Audi intends to extend the offer to its affected owners, too. As with the previous goodwill package, participating customers would receive a $500 prepaid Visa card and $500 to use at dealers. The EPA issued a violation notice against the 3.0 TDI in November and later extended it to additional model years. Audi later admitted that the engine, which was also in the Touareg and Porsche Cayenne, had undisclosed emissions management software. However, the automaker limited the goodwill package only to the 2.0-liter powerplant while it investigated the allegations against the larger mill. VW has not announced a recall plan in the US for the 2.0 TDI so far, but VW Group CEO Matthias Muller recently outlined a possible solution that could fix about 430,000 of the 482,000 affected vehicles. "We have one [catalytic converter] in the works and we believe that will be a part of the technical solutions," he told Reuters. Muller plans to discuss the repair while in Washington D.C. on Wednesday to meet with the EPA. "I think we can now offer a package that will come very close to what the EPA is expecting from us," Muller said to Reuters. He also suggested the company might buy back some affected models but didn't confirm the recent rumor claiming that the buy-back may cover as many as 115,000 cars.

VW confirms Audi's emissions test transmission anomalies

Just a week after reports that the California Air Resources Board (CARB) found an emissions cheat in some Audi automatic transmission software programs, parent company Volkswagen has come clean. As reported by Reuters, VW's response to an article by Munich's Sueddeutsche Zeitung stated that the adaptive shift functionality can "lead to incorrect and non-reproducible results." Adaptive shift programs alter the characteristics of a vehicle's transmission to suit different driving styles. Gentle driving will result in earlier shifts and lower engine revs, while hard-charging on the pedals and steering will make the transmission more responsive and hold gears longer. That adaptation can change over time or even on a short-term basis. And it can save fuel. The difference in this case is that is seems that the Audi transmissions were specifically programmed to detect emissions test conditions. As we explained in a previous article, one of those test conditions is keeping the wheel straight. Turning more than 15 degrees shuts the test mode off. According to Reuters, the US government is trying to determine whether this classifies as an emissions cheat device, although VW, Audi, and the EPA have not commented on the record. This latest accusation is separate from the larger VW diesel emissions scandal. Related Video: Image Credit: Getty Editorial Government/Legal Green Audi Volkswagen Emissions vw diesel scandal
