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 forced to sell stake in Suzuki

The six-year-long failed marriage between Volkswagen and Suzuki has finally come to an end. Almost. An arbitration panel in London issued its final verdict which, according to a VW press release, cleared Suzuki in terminating the agreement, so VW now needs to get rid of its 19.9-percent share. However, the tribunal's decision said VW performed all of its obligations and Suzuki didn't – the Japanese carmaker should have given VW last-call rights for a delivery of diesel engines, but failed to. The breach opens Suzuki up to damage claim, but so far VW only says it reserves the right to sue. Now that Suzuki has an outside investor to provide funds it meant to get from VW, perhaps both can get back to their reasons for being. The press release is below. Ruling in arbitration proceedings: Cooperation between Volkswagen and Suzuki deemed terminated - Arbitral tribunal confirms Volkswagen met contractual obligations and finds that Suzuki has ordinary right to terminate agreement based on reasonable notice - Volkswagen to dispose of its 19.9 percent stake in Suzuki and expects positive effect on Company's earnings and liquidity from transaction - Arbitrators also find that Suzuki breached its contractual obligations to Volkswagen under the agreement and that Volkswagen has right to claim damages Wolfsburg, 30 August 2015 - An arbitral tribunal in London has announced its ruling in the dispute between Suzuki Motor Corporation and Volkswagen Aktiengesellschaft. As a result, cooperation between the two parties is deemed terminated. The arbitrators confirmed that Volkswagen met its contractual obligations under the cooperation agreement and found that Suzuki has terminated the agreement upon reasonable notice. Volkswagen will therefore now dispose of its 19.9 percent stake in Suzuki and expects a positive effect on the Company's earnings and liquidity from the transaction. The arbitral tribunal also confirmed that Suzuki breached its contractual obligations to Volkswagen under the agreement and that Volkswagen has the right to claim damages. "We welcome the clarity created by this ruling. The tribunal rejected Suzuki's claims of breach and found that Volkswagen met its contractual obligations under the cooperation agreement. Nevertheless, the arbitrators found that termination of the cooperation agreement by Suzuki on reasonable notice was valid, and that Volkswagen must dispose of the shares purchased.

Poor headlights cause 40 cars to miss IIHS Top Safety Pick rating

Over the past few months, we've noticed a number of cars and SUVs that have come incredibly close to earning one of the IIHS's highest accolades, the Top Safety Pick rating. They have great crash test scores and solid automatic emergency braking and forward collision warning systems. What trips them up is headlights. That got us wondering, how many vehicles are there that are coming up short because they don't have headlights that meet the organization's criteria for an "Acceptable" or "Good" rating. This is a revision made after 2017, a year in which headlights weren't factored in for this specific award. This is also why why some vehicles, such as the Ford F-150, might have had the award last year, but have lost it for this year. We reached out to someone at IIHS to find out. He responded with the following car models. Depending on how you count, a whopping 40 models crash well enough to receive the rating, but don't get it because their headlights are either "Poor" or "Marginal." We say depending on how you count because the IIHS actual counts truck body styles differently, and the Infiniti Q70 is a special case. Apparently the version of the Q70 that has good headlights doesn't have adequate forward collision prevention technology. And the one that has good forward collision tech doesn't have good enough headlights. We've provided the entire list of vehicles below in alphabetical order. Interestingly, it seems the Volkswagen Group is having the most difficulty providing good headlights with its otherwise safe cars. It had the most models on the list at 9 split between Audi and Volkswagen. GM is next in line with 7 models. It is worth noting again that though these vehicles have subpar headlights and don't quite earn Top Safety Pick awards, that doesn't mean they're unsafe. They all score well enough in crash testing and forward collision prevention that they would get the coveted award if the lights were better.
