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 to keep hiring workers despite VW diesel scandal

Even while Volkswagen contemplates delaying or canceling projects to pay for costs related to the massive diesel emissions scandal, its stablemate Audi is hiring, according to Reuters. Audi certainly isn't immune to the diesel scandal, with around 2.1 million affected vehicles worldwide including 13,000-14,000 in the US, but the scandal so far isn't affecting staffing levels. "We are sticking with plans for strategic growth and are continuing to hire new employees as planned," Audi board member for human resources Thomas Sigi said in a German newspaper, according to Reuters. Sigi even suggested paying a "respectable" bonus to workers next year. Audi has some big projects on the horizon, too. Among them, the company intends to launch a production version of the E-Tron Quattro Concept in 2018, and for performance fans a new TT RS appears to be on the way. The new A4 should be a big contributor to global volume when its worldwide rollout is complete. Rather than allowing the diesel scandal to hurt all of its divisions, the VW Group instead wants to concentrate the fallout (and costs) on the VW brand, according to Reuters. Those expenses could be huge. Volkswagen is budgeting around $7.3 billion just to repair the 11 million emissions-cheating vehicles. Worldwide, maximum estimates put the whole mess at $87 billion.

Italy To Monaco In Ingolstadt's Crushing Performance Saloon
I had an engagement a while back with the Audi RS5 Cabriolet in Monaco, and getting me from my lair in northern Italy by plane connection is an utter waste of time since the first flight is always to either Paris, Zurich, or Rome, three cities not at all on the way to Monaco. So I phoned Audi Italia about a quick loan of a car for the three-hour-ish drive to this event, and they were simpatici enough to propose that I keep whatever they gave me for two weeks. And what they gave me was a loaded Audi S8 with properly chosen 20-inch Dunlop SP Winter Sport treads attached.
This was about to be a much cooler two weeks than I had planned.
