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.

10 of 18 midsize SUVs earn 'good' IIHS side impact safety rating

It's not terribly surprising that midsize SUVs earned better safety ratings than small SUVs in the latest side-impact tests performed by the Insurance Institute for Highway Safety (IIHS). Just how much better they scored, on the other hand, certainly raises an eyebrow. Ten out of 18 midsize SUVs earned the highest rating of 'good' in the stringent new test, altered for vehicles starting with the 2020 model year with a heavier barrier (4,200 pounds) that moves at a higher speed (37 miles per hour) and is fitted with a hard honeycomb frontal structure. By way of contrast, just one out of of 20 small SUVs earned a 'good' score.  SUVs that receiving 'good' scores were the Ford Explorer, Infiniti QX60, Lincoln Aviator, Mazda CX-9, Nissan Pathfinder, Subaru Ascent, Toyota Highlander, Volkswagen Atlas, Volkswagen Atlas Cross Sport and Volkswagen ID.4. For EV fans, it's worth noting the ID.4 was the only electric vehicle included in the test. The Buick Enclave and Chevrolet Traverse scraped away with 'acceptable' ratings while the Honda Passport, Honda Pilot, Hyundai Palisade, Jeep Wrangler 4-door, Kia Telluride and Nissan Murano were deemed merely 'marginal' in the tough new test. Only two models — the Mazda CX-9 and Volkswagen ID.4 — earned a "Good" rating in every test category.  Interestingly, the Jeep Wrangler would have scored a 'good' rating if it were equipped with side airbags for the rear seating positions. It would likely be an engineering challenge to equip its removable top and/or doors with airbags, but the lack of that safety feature allowed the head of the rear passenger dummy to hit the vertical support of the top. Otherwise, the Wrangler scored good ratings across the board. The new Ford Bronco, which makes more allowances for side-impact safety, has not yet been tested.  The popular Hyundai Palisade and Kia Telluride SUVs stand out in the test with 'poor' ratings for driver pelvis injuries. The Nissan Murano, a vehicle last redesigned for the 2015 model year, was the only vehicle tested that received a 'poor' rating for its structure and safety cage. Videos of the tests of 12 of these 18 SUVs can be found on the IIHS' YouTube page.

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.
