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.

Automakers drop support for Trump effort against California emissions

WASHINGTON — Toyota, Fiat Chrysler (now known as Stellantis following its merger with Peugeot) and other major automakers said on Tuesday they were joining General Motors in abandoning support for former President Donald Trump's effort to bar California from setting its own zero emission vehicle rules. The automakers, which also included Hyundai, Kia, Mitsubishi, Mazda and Subaru, said in a joint statement they were withdrawing from an ongoing legal challenge to California's emission-setting powers, "in a gesture of good faith and to find a constructive path forward" with President Joe Biden. The automakers, along with the National Automobile Dealers Association, said they were aligned "with the Biden administrationÂ’s goals to achieve year-over-year improvements in fuel economy standards." Nissan in December withdrew from the challenge after GM's decision in November shocked the industry and won praise from Biden. On Monday, the Justice Department asked the U.S. Appeals Court for the District of Columbia to put the California emissions litigation on hold to "ensure due respect for the prerogative of the executive branch to reconsider the policy decisions of a prior administration." Biden has directed agencies to quickly reconsider TrumpÂ’s 2019 decision to revoke CaliforniaÂ’s authority to set its own auto tailpipe emissions standards and require rising numbers of zero-emission vehicles, as well as Trump's national fuel economy rollback. Asked to respond to the automakers' action, White House climate adviser Gina McCarthy said in a statement that "after four years of putting us in reverse, it is time to restart and build a sustainable future, grow domestic manufacturing, and deliver clean cars for America." California Governor Gavin Newsom praised the automakers on Twitter for "dropping your climate-denying, air-polluting, Trump-era lawsuit against CA" and urged them to join the voluntary framework. TALKS WITH BIDEN Separately, an industry trade group on Tuesday proposed to start talks with Biden on revised fuel economy standards that would be higher than Trump-era standards but lower than ones set during the prior Democratic administration. The Trump administration in March finalized a rollback of U.S. Corporate Average Fuel Economy standards to require 1.5% annual increases in efficiency through 2026, well below the 5% yearly boosts under the Obama administration rules it discarded.

Volkswagen reveals Golf GTI Clubsport concept at Worthersee

The various brands under the Volkswagen Group umbrella are bringing a slew of hot hatch concepts to the GTI-Treffen in Worthersee, Austria, this week – but the gathering wouldn't be complete without a version of the headline Volkswagen Golf GTI. And here it is. Previewed with initial details and a trio of design sketches last week, VW has now released a proper array of images showing the GTI Clubsport concept. The enhanced GTI packs an upgraded version of the stock version's 2.0-liter turbo four with 261 horsepower on tap, favorably splitting the difference between the standard GTI with the Performance package and the more potent Golf R. An overboost function even kicks in an extra 10-percent more horsepower to bring peak output up to 287 hp – just a few horses shy of the R's 292, but driving only the front wheels. As you can see, the Clubsport concept also features a more aggressive aero kit as well as upgraded rolling stock with semi-slick rubber. Most, if not all, of these enhancements are earmarked to find their way onto a 40th anniversary edition GTI, but we're unlikely to see that model in US showrooms. World premiere of the Golf GTI Clubsport at Lake Worthersee - Exclusive anniversary model for 40th birthday of the GTI - Golf GTI Clubsport debuts with 265 PS and boost function Next year, the Golf GTI celebrates its 40th birthday. Volkswagen is marking this historic event with a progressive anniversary model: the new Golf GTI Clubsport. Volkswagen will be showcasing the Golf GTI Clubsport on 14th May as part of the legendary GTI meet at Lake Worthersee, when it will make its world premiere in the form of a near-production concept car. With a power output of 195 kW / 265 PS (35 PS more than the Golf GTI Performance) and top performance temporarily increased by around a further 10 per cent thanks to a boost function, the Golf GTI Clubsport is set to take off at the start of 2016 as the most powerful production 'GTI' yet. The anniversary model is being launched not only with an extremely powerful engine, but also with an individualised interior and exclusive bodywork details. The design modifications include a completely new front bumper, new side sills, a new and aerodynamically highly innovative roof-edge spoiler and a specially developed rear diffuser. All of these features were designed with the aim of further enhancing the GTI's performance and of thereby bringing form and function into perfect harmony.
