Bentley considering diesel engine for new SUV

Turns out, in case you didn't know, the rich are just like regular people. They too are concerned about the environment, even when tooling around town in their super-luxurious Bentleys. So the automaker is weighing the idea of offering a diesel engine in its SUV offering, which could help satisfy customers' demands for more fuel-efficient engines.
Chairman and CEO Wolfgang Schreiber told Autoblog in a roundtable interview at the Geneva Auto Show that the automaker is researching whether or not a diesel engine makes sense for the brand. Bentley, owned by the Volkswagen Group, could in theory use a diesel engine from anywhere in the Volkswagen Group family. We at Autoblog have hopes they'll revive the V10 TDI used in the VW Touareg until 2010, but ever-stricter emissions laws would likely make that problematic.
But rich people aren't so much like us that they'll be worried about petty things like pricing. Schreiber admitted the diesel engine could be a $15,000 option, which he said customers would probably find "acceptable." Given that the cheapest Bentley today starts at $177,000, typical customers probably won't be diddling around worrying about an extra 15 grand.

Volkswagen's emissions deception brings more scrutiny to entire industry

Volkswagen's emissions deceptions have hurt the entire auto industry's credibility with federal regulators. Days after the world's largest automaker confessed to installing software that circumvents emissions standards on approximately a half-million diesel vehicles in the United States, a top federal safety official says the company's dishonesty will force government officials to view the entire auto industry with heightened skepticism. "Your first question has to be, 'How extensive is it through the whole industry?' You don't know if it's a unique case or if other people are doing it," said Mark Rosekind, administrator of the National Highway Traffic Safety Administration. "The unfortunate part is you're not going to worry about one person. It's extended to the entire industry. If they did it, someone else could do it." "They tell you one thing, you question it." - Mark Rosekind Rosekind's agency doesn't bear responsibility in investigating the emissions cheating. That falls to the Environmental Protection Agency, which served Volkswagen with a Notice of Violation on Friday that alleged the company's diesel vehicle equipped with 2.0-liter engines contained a defeat device that allowed the cars to detect when emissions testing was taking place. In normal driving situations, the cars spewed pollution at as much as 40 times allowable thresholds. But because of the emissions cheating, NHTSA wonders if the German automaker has been cutting corners on safety standards or disingenuous on safety-related discussions. Speaking at an auto-industry event in Novi, MI, on Tuesday, Rosekind indicated no information can now be taken at face value. He used the phrase "Question assumptions" several times in discussing the case. "Of course, question assumptions means, 'Is there some other safety element there that we're now going to have to investigate?" he said. As it did in the General Motors ignition-switch probe, the Department of Justice has initiated an investigation of Volkswagen and the House Committee on Energy and Commerce announced it will hold hearings on the cheating. For NHTSA, criminal cases complicate matters. The agency core function is to regulate safety, not conduct criminal investigations. But in the early going, their investigators may be the first ones to spot wrongdoing.

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.
