After VW scandal, new emissions tests may drive up diesel prices

However much Volkswagen has to aside to address the flak from the company's ongoing diesel-emissions scandal, it could still be less expensive than the cost of making diesels realistically adhere to stricter emissions-testing mandates. New rules are likely to be put into place as a result of the revelations that as many as 11 million VW diesel vehicles were programmed to game the emissions-testing system by triggering artificially low emissions levels. There's a potential problem, though, according to the European Automobile Manufacturers' Association (ACEA). Governments around the world are calling for more intense tests that would better simulate real-world driving conditions. Some of the mandates suggested by the European Union could make the process a costly one, however. And that would boost diesel-vehicle production costs to the point that the lower refueling costs via cheaper fuel and better fuel economy won't be able to justify the higher purchase price. According to Reuters, the ACEA issued a statement that said: The automobile industry agrees with the need for emissions to more closely reflect real-world conditions, and has been calling for proposals for years. However, it is important to proceed in a way which allows manufacturers to plan and implement the necessary changes, without jeopardizing the role of diesel as one of the key pillars for fulfilling future CO2 targets." Diesels have long been pushed in Europe because the lower carbon dioxide from the better fuel economy was thought to outweigh the additional nitrous oxides spit out by the oil burners. The push for "clean diesel" in recent years was supposed to reduce NOx emissions as well, but the VW story shows that this wasn't always the case. Rejiggered testing in Europe may start as early next year, and results may be available as soon as late 2017, but the whole point may become moot if automakers cut back on making diesel vehicles. The French government is already talking about eliminating diesel-vehicle subsidies in the wake of the scandal. Still, while new-diesel vehicle prices may rise, used-diesel prices may be falling. US auction prices for VW diesel vehicles are already down about 13 percent. UK diesel-vehicle prices have also declined, just not as much. Related Videos:

VW decides against active-cooling system for e-Golf lithium battery

When the 2015 VW e-Golf was introduced at the LA Auto Show last year, VW said it would come with a water-cooled battery. During the Detroit Auto Show, when the car was trotted out again, VW released a new press release that stripped out the "water-cooled" language, but this change went unnoticed. During a recent VW event in Germany, a friend from Green Car Reports realized that the battery on display did not seem to have any water-cooling mechanisms. That set us off on a bit of a sleuthing and we have now learned that VW is not going to include any active cooling in the upcoming e-Golf. In fact, the company is entirely confident that this car - because of what it's designed to do - doesn't need it. "The need for a cooling system wasn't there" - VW's Darryll Harrison VW has been working on an electrified Golf for ages now, and so changes to the plan are to be expected. But battery cooling is vitally important not just to keep the car operating properly but because when things get too hot, there can be serious public relations problems. Nissan began testing a new battery chemistry for the Leaf in 2013 after an uproar from warm-weather EV drivers in Arizona who were experiencing worse-than-expected battery performance. The Leaf has always used an air-cooled battery, which is another way to say that there is no active cooling system (more details here). Tesla CEO Elon Musk once said this approach is "primitive." So, why is VW following the same path? We asked Darryll Harrison, VW US's manager of brand public relations west, for more information, and he told AutoblogGreen that VW engineers discovered through a lot of testing of the Golf Mk6 EV prototypes, that battery performance was not impacted by temperatures when using the right battery chemistry. That chemistry, it turns out, is lithium nickel manganese cobalt oxide (NMC) in cells from Panasonic. These cells had "the lowest self-warming tendency and the lowest memory effect of all cells tested," Harrison said. He added that VW engineers tested the NMC cells in places like Death Valley and Arizona and found they didn't warm very quickly either through operation, charging (including during fast charging) or through high ambient temps. "The need for a cooling system wasn't there," Harrison said.

2016 VW diesels are still 'months' out

Many 2016 model year vehicles are already for sale at dealers in the US but none of them have Volkswagen's 2.0-liter TDI. Don't expect to see the diesels on lots for several months either. The Environmental Protection Agency is preparing an onslaught of evaluations on the engine to make sure that it doesn't get fooled again, Automotive News reports. Before the new tests can even begin, VW must resubmit the 2016 diesels to the EPA, and the company isn't saying when that might be. The automaker took back the models' previous application after telling the EPA about an undisclosed software feature, according to Automotive News. There was absolutely no evidence that this was another defeat device, but the emissions agency wanted more information about what the tech's effect was. EPA boss Christopher Grundler has been quite clear about not disclosing any details about the new tests. He doesn't want to give automakers a chance to create more defeat devices, and the agency intends to evaluate diesels from other companies with more rigor, too. That process is already beginning in cases like subjecting the 2016 Chevrolet Colorado Duramax to on-road emissions checks. Once the 2016 VW models are certified, the EPA intends to run the same tests on the proposed repairs for the company's earlier diesels. That process could take months, as well, according to Automotive News. VW CEO Matthias Muller recently said that the first recalls likely wouldn't happen until January.
