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 R8 Spyder looks like heaven at the Green Hell

After Audi took the wraps off the new R8 coupe at the 2015 Geneva Motor Show, we knew it would only be a matter of time before the convertible version arrived. Now, we've spotted the droptop during testing on and around the venerable Nurburgring Nordschleife in Germany. The new Audi R8 Spyder is expected to closely mirror the fixed-roof supercar we've already seen. Only instead of a tin top, of course, it'll have a folding fabric roof mechanism. This goes against the recent retractable hardtop trend, and the featured is used by the Ferrari 488 Spider and McLaren 650S Spider. Some revised air vents appear to be part of the R8's convertible package, as well. Otherwise, we can anticipate the same specs as the R8 coupe. The latest model ditched the previous version's V8 engine in favor of 10-cylinder options: a 5.2-liter V10 with either 533 horsepower in "base" spec or 602 hp in the V10 Plus model. Both drive all four wheels through a seven-speed dual-cluch transmission. The jury's still out on whether Ingolstadt will slot a smaller engine option into the R8, particularly for markets where tax brackets are determined by engine displacement. But whatever the coupe gets, the convertible is likely to offer it as well. Related Video:

The Volkswagen Group switches official language to English

The Volkswagen Group can't be fairly thought of as entirely German anymore, so the news that the company is switching its official language to English to help attract managers and executives is a rational, if surprising, decision. While many VW Group companies are still staidly German in character and culture, consider the other companies that it controls: Bentley (British), Bugatti (French), Ducati and Lamborghini (Italian), Skoda (Czech), Scania trucks (Swedish), and SEAT (Spanish). Not to mention the large Volkswagen Group of America operation, which constructs cars in Chattanooga, TN. Volkswagen's explicit motivation is to improve management recruitment – making sure the company isn't losing out on candidates for important positions because they can't speak German – and that's inherently sensible in a globalized economy. Particularly considering, like it or lump it, that English is the lingua franca of said global economy. It also should make it inherently easier to communicate between its world-wide subsidiaries and coordinate operations. It's hard to say for sure if this will have any impact on the consumer, although it's easy to see the benefits if, say, VW Group hires some American product planners or engineers and they push for features and designs that more closely suit American needs. After all, the US is a hugely important market for any manufacturer, and so the switch to English almost certainly has something to do with the outsized influence of the US in the global economy. And there doesn't seem to be a downside from a purely rational perspective, although it could mean that the Group's corporate culture becomes less German. Whether that's a good or a bad thing depends on your perspective.
