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.

VW recalls another 6,700 vehicles over fuel leak [UPDATE]

UPDATE: An earlier version of this post suggested that the expanded recall involved an additional 44,658 units, when VW tells us that is in fact the total number - adding a further 6,679 to the original recall of 37,979. The text below has been updated accordingly, with our apologies for the confusion. It was a little over a month ago that Volkswagen issued a recall for some 38,000 vehicles over a potential fuel leak. Now the German automaker and the National Highway Traffic Safety Administration have expanded that recall, affecting even more vehicles for the same issue. The problem revolves around a sealing cap at the fuel rail, which could fail and cause fuel to leak into the engine compartment, thereby increasing the risk of a fire. This time around, VW is calling in a selection of Jettas, Passats, Golfs, GTIs, Beetles and Beetle Convertibles, all of them from the 2014 and 2015 model years (except the Golf and GTI, of which only 2015 models are being recalled). The recall now affects an estimated additional 6,679 units, which (in addition to the 37,979 recalled previously) brings the total up to 44,658 vehicles across the United States. RECALL Subject : Fuel Leaking Into Engine Compartment Report Receipt Date: JAN 23, 2015 NHTSA Campaign Number: 15V028000 Component(s): FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 44,658 Manufacturer: Volkswagen Group of America, Inc. SUMMARY: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2014-2015 Jetta vehicles manufactured March 28, 2014, to November 24, 2014, 2014-2015 Passat vehicles manufactured April 7, 2014, to November 18, 2014, 2015 Golf and GTI vehicles manufactured July 1, 2014, to November 20, 2014, and 2014-2015 Beetle and Beetle Convertible vehicles manufactured March 31, 2014, to November 27, 2014. A sealing cap at the fuel rail may fail, allowing fuel to leak into the engine compartment. CONSEQUENCE: A fuel leak, in the presence of an ignition source, can result in a vehicle fire. REMEDY: Volkswagen will notify owners, and dealers will replace the fuel rails with new parts, free of charge. The recall is expected to begin in early February 2015. Owners may contact Volkswagen customer service at 1-800-822-8987. Volkswagen's number for this recall is 24BL. Note: This recall expands and supersedes recall 14V-809 (Volkswagen recall number 24Bi) and only affects vehicles not previously repaired under that campaign.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.
