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.

VW confirms new TDI for second half of 2014 in Golf, Jetta, Passat and Beetle

Diesel lovers rejoice. Volkswagen is bringing the latest iteration of its 2.0-liter four-cylinder diesel engine - dubbed the EA288 - to the 2015 model year Golf, Jetta, Passat, Beetle (2013 model pictured above) and Beetle Convertible, and the cars will be on sale in the second half of 2014.
While it shares its moniker with the old diesel, the new engine produces 150 horsepower, a 10-hp boost, and 236 pound-feet of torque. VW promises improved fuel economy as well, but it hasn't announced specifically what amount yet. The company claims that despite the same displacement, only the bore spacing is shared with the previous version. The mill includes new features like exhaust gas recirculation, an intercooler integrated into the intake manifold and low-friction camshaft bearings.
VW Group of America has had great success with diesels in the US recently. Vee-Dub and Audi sold 105,899 diesel-equipped models in 2013. It was the first time the group ever sold over 100,000 diesels in a year, and they accounted for 24 percent of sales. Scroll down to read the full press release about the announcement.

Weekly Recap: 2016 CTS-V gives Cadillac new momentum for the new year

It's been a rough year for Cadillac. The historic luxury carmaker been in the news for all of the wrong reasons: Declining sales, ditching its advertising agency and the relocation of its headquarters from Detroit to New York. But in late December, Cadillac reminded everyone what it does best: Build some of the rawest and most compelling luxury sedans in the world, as evidenced by the 2016 CTS-V. This monster churns out 640 horsepower from a supercharged 6.2-liter V8. Sound familiar? That's the Corvette Z06 engine, and it makes this CTS the most powerful production Cadillac ever. It also puts the sporting divisions of the Germans on notice. The new CTS-V easily overpowers the Mercedes-Benz E63 AMG S 4Matic and its 5.5-liter biturbo V8 rated at 577 hp, and the BMW M5 (with the competition pack) and its 4.4-liter twin-turbo V8 that pushes out 575 hp. The rear-wheel drive Cadillac can sprint to 60 miles per hour in 3.7 seconds, which is close to the 3.5-second time turned in by the 4Matic-driven E63 S, and a bit quicker than the 4.1 seconds posted by the M5. With Magnetic Ride Control, General Motors' stout eight-speed automatic transmission (also used in the Corvette), Brembo brakes and a carbon-fiber option package that pretty much builds your car out of carbon fiber – it's clear this Cadillac means business. Truth be told, we expected this CTS-V to deliver. It's been a serious sports sedan for a decade, and the recent generation and its 556-hp arrogance have been particularly memorable. But notice what we're doing here? We're talking about product. Not who makes Cadillac's ads, or if the brand's headquarters has a mailing address in NYC. Like the 2016 ATS-V that's due in the spring, the debut of the 2016 CTS-V (on sale in late summer) is a shot in the arm for Cadillac, and its arrival comes during time of transition. The brand is trying to reinvent itself as a modern luxury maker. It wants new customers, a different image and obviously more sales. Those things are going to take time, but with a 640-hp sledgehammer of a sports sedan on tap for next year, Cadillac can still maintain some of its swagger through all of the change.
