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 formally introduces super-efficient XL1

Lightweight and low drag are hallmarks of great sportscar design. But when paired with a super-efficient, hybrid powertrain, you have the Volkswagen's XL1 that has been formally introduced in Geneva today.
When the 1,700-lb, carbon-fiber-bodied two-seater hits the road, its claimed 261 miles per gallon will make it the world's most-fuel-efficient production car. Though "production car" might be a stretch since VW said in a February press release that the XL1 would be built using "handcrafting-like production methods." We translate that to mean you won't be seeing many of these cars on the road. Though no one at VW has mentioned pricing yet, early rumors suggested a six-figure price tag.
That's supercar budget for a vehicle that has a 47-horsepower, two-cylinder diesel engine and a 27hp electric motor. With numbers like that, owners can expect 0-62 mph times of 12.7 seconds and top speed near 100 mph.

Lincoln Aviator returns, VW ponders pickups, and Subaru Forester endures

NEW YORK – Volkswagen is taking a hard look at a pickup truck, the Lincoln Aviator is back, and you love old Subarus (we'll explain). The New York Auto Show returned last week with flair and a wide range of promising reveals. Let's break down some of the big news, plus a few things you might have missed. News: Ford is fortifying Lincoln with the Aviator SUV Views: Doing a mid-size SUV is obvious. Calling it the Aviator wasn't. I like it. Using Navigator design cues, this thing looks the part and should give Lincoln some energy and sales volume. Not playing in the midsize SUV segment has been a mistake for Ford's luxury brand, and the Aviator should fill a much-needed hole. Props to Lincoln for dusting off the Aviator name, most recently used on a rebadged Ford Explorer built in 2003-2005. It sounds classy and historic, like something from 1930s, even though it only dates to the tail end of the " Friends" era. Speaking of names, when the MKC gets a new one, Lincoln should dust off Zephyr, a moniker it actually used in the '30s and then briefly in the early 2000s. Why use the Aviator name? Jim Farley, Ford's president of global markets, said it's about reminding consumers that Ford has traditionally built strong SUVs. "I think in a way the legacy is falling in love with what we do best," he said. "We wanted to go back to our roots. We know how to do this well." Farley also said the Aviator could prove to be Lincoln's bestseller. The Aviator was well-received in New York, earning our Best in Show award and garnering cautiously optimistic reactions from some analysts. "Lincoln ran this experiment once before ... differences in the market conditions, stronger differentiation and appetite for utility vehicles may prove a different story for this Aviator," IHS analyst Stephanie Brinley said. View 19 Photos News: VW surprised the car world with the Atlas Tanoak pickup concept Views: Good move. VW should build this. The concept is based on a longer version of the Atlas platform and would take aim at the midsize truck segment. VW is using this prototype to "gauge the reactions" of automotive influencers, but make no mistake, the Tanoak is totally doable. Using Atlas bones and mechanicals punched up with rugged styling and some soft-road capability, the Tanoak would grow VW's portfolio in a smart way. The Atlas Cross Sport concept, also revealed in New York, signals that Atlas expansion is already underway.
