Recharge Wrap-up: VW Golf TDI wins green car award, DC buses might go electric

The 2015 Volkswagen Golf TDI has won the award for 2014 Northwest Green Car or the Year. The distinction comes from the Northwest Automotive Press Association during its Drive Revolution event in Portland. Co-chairman of the event, Jeff Zurschmeide, says, "Volkswagen has led the diesel passenger car market for years, and the Golf TDI proves that they're likely to stay on top for a while." The 2015 Golf TDI has 10 more horsepower than the outgoing model, while improving fuel economy thanks to a new engine. It also has a base price $3,000 lower than the 2014 Golf TDI.

The laser lights use half the energy of their LED counterparts, according to BMW, which is important when one is trying to get every last bit of range out of the car's battery. The laser high beams can also reach about twice as far as LED lighting. Because of their brightness, they won't be available on cars sold in the US. In laser-equipped i8s, the laser high beams will not work below 60 kilometers per hour, nor when other lights are detected in front of the vehicle. Head to Automotive News Europe to read more. Renault has delivered a fleet of 30 Kangoo ZEs to Uruguay's government-owned power company, UTE. The electric fleet will allow the company to reduce its CO2 emissions by 36 metric tons, says Renault. 84 percent of Uruguay's electricity comes from renewable sources, with a goal of 90 percent on the horizon. Uruguay aims to get a third of its electricity from wind farms by 2016, meaning these Kangoo ZEs will be powered in no small part by renewable energy. For Renault, "This order is a further sign of the interest in the region for electric vehicles," according to Denis Barbier, Renault's senior vice president, citing previous deliveries in Brazil, Mexico, Argentina and Colombia.

Some of the diesel buses, which were first put to work in 2003, are nearing the end of their life cycle, and DC sees an opportunity to make the switch to something a little greener. "Electric has not been a viable option in previous procurements, but now it is," says Will Handsfield, Georgetown Business Improvement District's transportation director. Handsfield is concerned about air quality, and says he also appreciates the long-term stability of electric rates compared to diesel.

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.

Volkswagen names Piech's nieces to supervisory board

Volkswagen was left with two vacancies on its supervisory board after Ferdinand Piech and his wife Ursula were forced out a few days ago, and now it's filled them. Intriguingly, however, both of the new directors are Piech's nieces. The most obvious connection is Julia Kuhn-Piech, a real-estate professional who has sat on the board of VW's Man truck subsidiary since last year. Kuhn-Piech, 34, is the daughter of Ferdinand's younger brother Hans-Michel Piech (and by extension, niece of the ousted chairman). The other seat is being filled by Dr. Louise Kiesling, 57, a designer and daughter of Ferdinand's late older sister Louise Daxer-Piech. Keeping track of the lineage of the Porsche-Piech clan can be confusing, particularly with so many Ferdinands and Louises, but it breaks down essentially as follows: All are descended from Ferdinand Porsche, founder of the eponymous automaker and credited as the designer of the original Volkswagen Beetle. Porsche had a son and a daughter, the latter being Louise Porsche, who married Anton Piech and had four children: Ernst, Louise (mother of incoming board member Louise Kiesling), Ferdinand (the ousted chairman) and Hans Michel, father of the other incoming board member Julia Kuhn-Piech and a board member of both the Volkswagen Group and Porsche SE as well. The Piech and Porsche families control Porsche SE, which holds 50.7 percent of shares in the Volkswagen Group, which in turn owns Porsche the automaker. With all that in mind, appointing other members of the Piech-Porsche clan to the board follows logically enough - particularly since other members of the family helped oust Ferdinand from the chairmanship in the first place. The nominations, incidentally, also help VW increase its proportion of female board members. The two incoming Piechs will join Annika Falkengren of Swedish bank SEB and Babette Frohlich of the same IG Metall union as the board's interim chairman Berthold Huber. Wolfsburg, 30 April 2015 Dr. Louise Kiesling and Ms. Julia Kuhn-Piech appointed new members of the Supervisory Board of Volkswagen AG Upon application by the Board of Management of Volkswagen AG, Dr. Louise Kiesling and Ms. Julia Kuhn-Piech were today appointed members of the Supervisory Board of Volkswagen AG by Braunschweig Local Court with immediate effect. The appointments were made pursuant to Section 104 of the Aktiengesetz (German Stock Corporation Act) and were occasioned by the recent resignations of Prof. Ferdinand K.
