VW quite interested in solid-state batteries for EVs

Volkswagen is about to make a decision about which advanced battery technology the automaker will seriously investigate to give its electric vehicles more range. VW will decide by July if it will use solid-state batteries made by US-based QuantumScape Corp. in future EVs, according to Bloomberg News. Last year, VW bought a five-percent stake in QuantumScape, which was founded by ex-Stanford University researchers. The lure is that QuantumScape's solid-state batteries may provide a single-charge range of as long as 430 miles. That's more than three times the current range of the VW e-Golf electric vehicle the company recently started selling to the public and is substantially longer than the single-charge range of the Tesla Model S electric sedan. The batteries are also fireproof, making VW's potential decision one with an eye towards more vehicle safety. Solid-state battery technology, in which solid lithium electrodes are used instead of liquid electrodes such as those in lithium-ion batteries, are the subject of research at other automakers and suppliers as well. Toyota says they could be here by 2020. Recently, the cordless vacuum cleaner maker Dyson acquired a $15-million equity stake in Michigan-based battery maker Sakti3 with the idea of using the startup's solid-state batteries in its products. General Motors also has a minority stake in Sakti3, which was spun off from the University of Michigan.

Which car should win 2015 World Green Car of the Year?

There were three finalists for the World Green Car of the Year announced about a month ago at the Geneva Motor Show: the BMW i8, the Mercedes-Benz S 500 Plug-In Hybrid and the Volkswagen Golf GTE. With the New York Auto Show upon us and the winner scheduled to be announced tomorrow, we thought it's high time to ask our readers which one should win. There were seven other vehicles named to the finalists list: the Hyundai x35/Tucson Fuel Cell, the Volvo XC90 T8 Twin Engine, the Audi A3 Sportback E-Tron, the BMW X5 xDrive40e, the Kia Soul EV, the Nissan e-NV200 and the Opel Adam 1.0 Direct Injection Turbo ecoFLEX Start. Would you have named one of these to the top three list instead? POLL 14386429 Green BMW Mercedes-Benz Volkswagen 2015 ny auto show world green car of the year vw golf gte

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.
