VW expanding in Chattanooga, hiring workers ahead of SUV production

Hey, look! We're writing about Volkswagen's Chattanooga, TN factory and the focus isn't on yet another unionization effort. That's because the big news at the still-new factory is VW's plan to expand and increase its workforce in preparation for the arrival of the German brand's long-awaited midsize crossover. The expansion, which will add over half a million square feet of factory space, overhaul the assembly, body and paint shop and add 2,000 employees to the factory's ranks, officially kicked off last month. "This is a very exciting time in the history of Volkswagen Chattanooga," president and CEO of operations at the plant, Christian Koch, said in a statement. "A lot of hard work is going into adding this second vehicle line to the plant, but it is crucial to our efforts to move forward in America." "Not only will Volkswagen's expansion create thousands of new jobs, it will strengthen their roots in our city," Chattanooga's Mayor, Andy Berke, said in a statement. "From the construction at the plant to the development of a visitors center, there is no doubt that Volkswagen is invested in Chattanooga." VW Chattanooga has been a constant in the headlines over the past few years as pro-union and pro-business interests have battled over the souls representation rights of its roughly 1,500 workers. Just over a year ago, the UAW was defeated in its initial unionization bid, although pro-labor interests have not gone quietly into the night. Construction is expected to continue for two years, with production of Chattanooga's second vehicle expected to commence in 2016. Scroll down for the official press release from Volkswagen. VOLKSWAGEN CHATTANOOGA'S PLANT EXPANSION UNDERWAY Feb 24, 2015 Construction Will Add 2nd Vehicle Line: New Midsize SUV CHATTANOOGA, Tenn. (Feb. 24, 2015) - Construction is underway at the Volkswagen Chattanooga manufacturing facility in preparation for production of an all new Midsize SUV. The first phase of construction started in early January 2015 and will continue for the next two years. Volkswagen Chattanooga CEO and President Christian Koch gave a site tour to Chattanooga Mayor Andy Berke and Hamilton County Mayor Jim Coppinger on Tuesday, highlighting the necessary expansion of the production areas in the body shop, paint shop and assembly areas.

Jay Leno brings a rotary-powered VW Beetle to the garage

It takes something really unique or inventive to pique Jay Leno's interest. His show, Jay Leno's Garage, has featured everything from concours-worthy classics to completely custom, home-built machinery. How do you get Leno to feature one of more than 20 million Beetles on his program? Stick a turbocharged rotary engine under the hood. The Beetle's owner, Mario Markakis, swapped the car's stock flat four-cylinder for the Wankel engine from a 1990 Mazda RX-7 Series 5 Turbo. The engine's 250 horsepower are fed through a reinforced version of the Beetle's stock four-speed transmission. That's about five times the original engine's output. It works well, with the car putting down some impressive times at the drag strip. Markakis did most of the work to the Beetle in his garage. In addition to the engine swap, he's modified the car's brakes, suspension, and interior. Check out the video to hear all the details of this custom Wankel-powered Volkswagen.

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.
