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.

Jaguar Land Rover remains bullish on diesels

Despite Volkswagen's recent diesel scandal, Jaguar Land Rover is pushing ahead with ambitious plans to roll out the technology across most of its lineup in the coming years. Jaguar and Land Rover will add diesel engine variants to every model in their lineups, except for the Jaguar F-Type sports car. Land Rover launched the Range Rover and Range Rover Sport with available 3.0-liter turbocharged V6 diesels, and together they have sold more than 330 units so far in September, their first month on sale in the United States. JLA officials say they've seen no fallout from VW's emissions problem and are adamant their diesels meet EPA standards. "That has been our strategy, and it is not changing," Joe Eberhardt, Jaguar Land Rover North America CEO, told the Automotive Press Association on Wednesday in Detroit. "You have to deal with the situations as they arrive. We are confident of diesel." Jaguar will get another diesel next year from its Ingenium engine family, which will initially be sold in the XE sedan and the F-Pace crossover. It's a turbo 2.0-liter four-cylinder unit and makes 180 horsepower and 317 pound-feet of torque. A JLR spokesman said the Ingenium has not yet gone through the EPA certification process, and the diesel-powered models will arrive in the fall. Jaguar also plans to add diesel engines to the flagship XJ and XF sedans. Land Rovers, including the Discovery and Evoque, will also get diesel options, and the company estimates the technology will offer 20- to 30-percent improvements in fuel economy, depending on the vehicle. Eberhardt said it is "too soon to tell" if the diesel market will be weighed down by Volkswagen's situation. The German automaker admitted to cheating on emissions tests to make its diesel-powered cars appear to run cleaner than they actually do in real-world situations. The ensuing outrage forced longtime VW chief executive Martin Winterkorn to step down and prompted a reorganization of the company, which faces legal and regulatory action around the world. Still, Eberhardt maintains JLR is "very confident" in its diesels, which are part of its strategy to grow sales around the world. Land Rover has experienced rapid growth under the ownership of Indian conglomerate, Tata Motors, while Jaguar is set to revitalize its lineup with new entries like the XE and F-Pace to reach a broader market segment.

Volkswagen Golf R Evo may debut at Beijing Motor Show

If a report in Auto Express is correct, a lighter, faster brother to the Volkswagen Golf R will be shown to the world at the Beijing Motor Show in April. Said to be called the Golf R Evo, the even harder hot hatch would be unveiled as one of those concepts that's practically a de facto presentation of the genuine thing. The Evo in its name will come from having a carbon fiber roof and CF in the bodywork, lighter wheels, thinner bucket seats up front and a roll cage instead of rear seats.
If there's a power increase, it's been described as "a small bump." However, as the report mentions, if the Jenny Craig regimen can drop 100 kilograms (220 pounds) from the the 3,247-pound weight of the European Golf R, then the Golf R Evo will do about the same damage on the scales as the Golf but have at least 50 more horsepower and 44 more pound-feet of torque.
Since we still don't have the current Golf, this isn't something that should keep you awake even if the 'concept' does become a production model. But it is good to know that the Golf R is really going to start pushing its boundaries.
