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.

Volkswagen rules out Eos successor

When Volkswagen introduced the Eos back in 2006, hard-top convertibles were all the rage – in North America, in Europe and around the world. But the trend, billed at the time as the best of both worlds, has long since subsided, leading to VW axing the Eos several months ago. And don't count on it getting a successor at some point down the line, either. At the Detroit Auto Show earlier this week, VW R&D chief Heinz-Jakob Neusser told Autocar that the Eos is down for the count. In fact it is "maybe the first model we take out of the market" in a reversal of the momentum that has seen the German automaker expand its lineup incrementally over the past several years – although the Chrysler-built Routan minivan was also canceled around the same time. The place the Eos occupied in VW's North American lineup is largely being taken by the more charismatic Beetle Convertible, and in Europe and other markets by the Golf Cabriolet that's still based on the previous-generation hatchback. The Eos, however, isn't the only hard-top convertible withdrawn from the market in recent years. Tin-top cabrios like the Lexus IS and SC, Cadillac XLR, Chrysler 200, Pontiac G6 and Volvo C70 have all gone the way of the dodo – as have Euro-market coupe-convertibles versions of models like the Ford Focus, Opel Astra, and Peugeot 207. The arrival of the Buick Cascada just goes to show that soft-roofed convertibles have won out, particularly as far as four-seat cabrios are concerned. The one notable exception where folding hard-tops are still gaining traction is among mid-engined exotic supercars like the Ferrari 458 and McLaren 650S, both of which opted for solid folding roofs instead of fabric ones. We've yet to see, however, which approach Lamborghini will take with the Huracan Spyder or Audi will with the next-generation R8, the predecessors of both of which featured fabric roofs.

Porsche again staring down another $1.8B in hedge fund lawsuits

The sequence of events from 2007 that began with Porsche's secret attempt to take over Volkswagen, and instead lead to Porsche being taken over by VW, continues to instigate lawsuits against the Stuttgart sports car manufacturer. A group of hedge funds that suffered over $1 billion in losses sued the car company in New York. Porsche had publicly stated it wasn't trying to buy VW, the hedge funds in question were shorting VW stock, and when Porsche's actual intentions were revealed, the stock shot up and the hedge funds took a beating.
The case was thrown out over the issue of jurisdiction, then appealed, only to see another suit filed on top of that. After that, most of the hedge funds withdrew their claims in New York and Porsche offered a 90-day window to refile in Germany where it is already fighting a number of other suits over the same issue. The hedge funds accepted the offer, refiling in Stuttgart for $1.8 billion in damages. According to Bloomberg, Porsche hasn't commented on the refiling, but as the same plaintiffs are involved, it's safe to assume that the carmaker still feels the case is "unsubstantiated and without merit." It has fared alright so far even in German courts, with two lesser cases against it thrown out last year.
