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.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

VW still set on Phaeton redux despite cost-cutting drive and losing $32k per car

While critically well regarded, the Volkswagen Phaeton has proven to be a vehicle largely unloved by luxury buyers around the world. Despite this, it refuses to die. While VW's luxury sedan hasn't been sold in the US since 2006 due to low sales here, it has soldiered on in Europe with occasional updates. As the model's long lifespan has been winding down, VW has decided to keep pushing the Phaeton into a new generation, despite in-house alternatives like the Audi A8 and Bentley Continental Flying Spur. The move might not make much business sense, but Volkswagen executives are determined to make the Phaeton work. According to market analysts speaking to Reuters, developing the next-gen luxury sedan on the MLB platform could cost as much as 650 million euros ($737 million), despite relying on the same underpinnings in the A8. It's not like the Phaeton is leading the luxury sedan sales ranks, either. Reuters notes VW produced just 5,812 of them in 2013 (the most current year with data), and from 2002 to 2012, the automaker reportedly lost 28,000 euros ($32,000) on each example sold. Conversely, Mercedes-Benz sold 103,737 units of its new S-Class in 2014, an astonishing 82.2 percent jump over the previous year. The decision to keep the Phaeton going doesn't seem to square with the VW brand's cost-cutting strategy. Boss Martin Winterkorn announced last year a plan to save 5 billion euros ($5.7 billion) annually in the coming years. That plan reportedly also includes killing off less profitable models. Apparently, VW can't just rip off the band-aid and get rid of the Phaeton. Even some VW bosses seem somewhat perplexed at the sedan's business case. When Reuters asked the company's US boss Michael Horn about selling the Phaeton here, he said. "That's a dangerous question. It's an image bearer with no relevance for volume." The next-gen Phaeton is scheduled to go on sale in Europe in 2017 or 2018, according to Reuters, which is about a year later than previous rumors. A US launch will reportedly follow in 2018 or 2019 with the plug-in hybrid and potentially even diesel versions on offer. A starting price around $70,000 is estimated.
