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.

Renault to name VW manager Luca De Meo as CEO

PARIS — Renault's board is set to meet later on Tuesday to approve the nomination of Luca de Meo, the former head of Volkswagen's Seat brand, as its next chief executive, two sources familiar with the matter said. The Italian-born executive, who stepped down from Seat earlier this month, is not due to take up his post at the French carmaker until towards July, due to negotiations around his contract, according to one of the sources. Renault declined to comment. De Meo is not expected to face any last minute hurdles in his nomination, and has already won tacit backing from parties including the French government, a Renault shareholder. His appointment fills one of the major gaps left at the firm as it tries to move past a year of turmoil following the 2018 arrest in Tokyo of former boss-turned-fugitive Carlos Ghosn, and reset its strained alliance with Japan's Nissan. Ghosn, who forged and oversaw the Renault-Nissan partnership for almost two decades, has since fled Japan and resettled in Lebanon, from where he has contested the financial misconduct charges against him and said the alliance was at risk of collapse. De Meo, along with Renault Chairman Jean-Dominique Senard, brought in last January from tire maker Michelin, will have his work cut out to turn around the firm. Like rivals, Renault is grappling with a downturn in demand, and has said it expects a slight decline in the car market in Europe, Russia and China this year. The firm has also presented 2020 as a make-or-break year for the alliance with Nissan and is under pressure to deliver on cost savings and joint projects. Automakers face pressure to meet stringent new emissions targets with less polluting models, and are also competing to produce innovations such as self-driving cars, which require large investments. De Meo, who speaks French, will be one of a growing handful of outsiders in senior company jobs in France. The 52-year-old started his career at Renault and has worked at Fiat and Audi among other brands. He is credited with revitalizing sales at Barcelona-based Seat, imbuing it with a more sporty image, though his portfolio will be markedly larger at Renault, whose brands include Dacia and Lada. Renault's finance chief Clotilde Delbos has been CEO on an interim basis since last October, when Thierry Bollore, a former Ghosn ally, was ousted by the board.

Everybody's doing flying cars, so why aren't we soaring over traffic already?

"Where's my flying car?" has been the meme for impending technology that never materializes since before there were memes. And the trough of disillusionment for vehicles that can take to sky continues to nosedive, despite a nonstop fascination with flying cars and a recent rash of announcements about the technology, particularly from traditional automakers. Earlier this month, Toyota applied for an eye-popping patent for a flying car that has wheels with spring-loaded pop-out helicopter rotors. The patent filing says the wheels/rotors would be electrically powered, while in on-land mode the vehicle would have differential steering like tracked vehicles such as tanks and bulldozers. At an airshow in July, Aston Martin unveiled its Volante Vision Concept, an autonomous hybrid-electric vertical takeoff and landing (VTOL) vehicle it developed with Rolls-Royce. Aston says the Volante can fly at top speeds of around 200 mph and bills it as a luxury car for the skies. Audi used the Geneva Motor Show in March to unveil a flying car concept called the Pop.Up Next it developed with Airbus and Italdesign. If the Pop.Up Next, an electric and autonomous quadcopter/city car combo, gets stuck in traffic, an app can be used to summon an Airbus-developed drone to pick up the passenger compartment pod, leaving the chassis behind. Audi said that the Pop.Up Next is a "flexible on-demand concept that could open up mobility in the third dimension to people in cities." But Audi also acknowledged that at this point it has no plans to develop it. The cash-stoked, skies-the-limit Silicon Valley tech crowd is also bullish on flying cars. The startup Kitty Hawk that's backed by Google co-founder Larry Page announced in June that it's taking pre-orders for its single-seat electric Flyer that's powered by 10 propellers and is capable of vertical takeoffs and landings. The current version can only fly up to 20 mph and 10 feet in the air and has a flight time of just 12 to 20 minutes on a full charge. The Flyer is considered a recreational vehicle, so doesn't require a pilot's license. Uber says it plans to launch its more ambitious Elevate program and UberAIR service in 2023. "Uber customers will be able to push a button and get a flight on-demand with uberAIR in Dallas, Los Angeles and a third international market," Uber Elevate promises on its website.
