To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

Audi will spend less on future technology as it focuses on future technology

It seems the very thing meant to be saved by Audi curtailing spending could also take a hit as a result. A report from Reuters outlines a few ways Audi will cut costs in the wake of its parent company's diesel scandal. While focusing on EVs, autonomous driving, and new connected technology instead of its current vehicle portfolio, Audi is axing plans for a track to test self-driving cars as well as facilities meant to produce new concepts and batteries. Or, you know, exactly the kinds of things Audi is now focusing its efforts on. Some of this shouldn't come as a surprise. We already know about the death of the R8 E-Tron, a low-volume EV that wasn't going to make the brand much money and didn't pan out as a halo electric car quite like the company probably hoped. Then there's the new E-Tron crossover, which has been in the works for a while and will head a line of consumer-grade EVs from the brand – the kind that will make money as long as they sell in mass-market numbers, something Tesla has shown is possible. That project is surely safe, although perhaps it will now take longer for the EVs to gain autonomous abilities. This change in funding direction could mean that the planned autonomous track, dubbed IN-Campus as it was to be located in Audi's home of Ingolstadt, was going to be more for show than actual research, or that Audi thinks it can get the same outcomes in its existing facilities or new ones located elsewhere. (The company's work council is upset by the plan being put on hold, as it could mean more jobs leaving Germany.) There's also the very strong possibility that this provides a welcome opportunity for the company to cut some fat. Reuters notes that Audi spends more on R&D than rivals BMW and Mercedes-Benz, despite having the whole VW Group to leverage. While the diesel scandal was certainly not welcome, it may be forcing Audi and the other Group brands to take a closer look at balance sheets than they otherwise would have. The result of all of this could be a leaner company, assuming too much attention doesn't stray to low-volume EVs and away from what are still the core products.

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.
