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.

VW announces reworked 6.0 W12 TSI engine

Nobody makes more engines with a dozen cylinders than the Volkswagen Group. They're W12s, of course, owing to the novel shape of their cylinder banks. Now the German industrial giant has announced a comprehensively reworked version of that engine at the same Vienna Motor Symposium where it presented its new 2.0-liter turbo four. The new W12 retains the same arrangement and the same 6.0-liter displacement, but updates it all with the latest powertrain tech. In place of Audi's FSI direct injection and Bentley's TMPI multi-point injection, the engine has adopted a new TSI system. It's also got a pair of new twin-scroll turbochargers, APS-coated cylinders, a new cooling system, active engine mounts, cylinder deactivation, and a stop/start system. And – crucially for application in the upcoming Bentayga – it has an oil circuit designed for off-road use. The revised package now produces 600 horsepower and 664 pound-feet of torque. Considerably more than the 567 hp and 516 lb-ft offered in the Bentley Continental GT W12, but less than the GT Speed, which we suspect will get an even more powerful version of this new engine. It's also more powerful than even the top version of Audi and Bentley's 4.0-liter twin-turbo V8, to make the W12 a more compelling option. Of course that's just as far as the Continental GT is concerned. The W12 has also found use in the Continental GTC and Flying Spur, as well as the Volkswagen Phaeton and Audi A8, and could find further applications under the Flying B emblem and elsewhere in the future. VW says that in the right application (say, in the production version of the Bentley EXP 10 Speed 6 concept, for example), the new twelve-pot could deliver 0-62 times of under four seconds and a top speed in excess of 186 miles per hour.
