How VW's hyper-efficient XL1 will influence the next Golf

In 2007, the European Union mandated fleet average CO2 emissions of 158.7 g/km. For 2015, that figure will drop to 130 g/km, and the target for 2020 is an ambitions 95 g/km. Thanks to some German politicking, that target will be phased in from 2020 to 2024, but it will still apply to 80 percent of passenger cars in that first year. In US miles per gallon, that's the equivalent of going from about 35 mpg to 42 mpg to 57 mpg. The current Volkswagen Golf is rated from 85 g/km of CO2 to 190 g/km depending on model - and zero for the e-Golf, so for the next-generation MkVIII hatch due in 2019, to meet the goal, Volkswagen engineers will need to introduce a bunch of new tricks. According to a report in Autocar, VW be mining its hyper-efficient XL1 for some of them.
Predictions for the next Golf include a variable-compression engine, an electric flywheel and an electric turbo, along with taking greater advantage of coasting. Volkswagen could be getting help from Audi with the electric turbo and variable-compression engine and electric turbo, with Audi already having shown off the former and brand technical boss Ulrich Hackenberg confirming the VW Group is working on the latter. It's possible the flywheel system could also have the mark of The Four Rings: Autocar mentions a British system that Volvo is testing, but the R18 e-tron Quattro racer has been using one for years.
The need for such features is because the company won't be able to net enough future gains from just aerodynamic improvements and advanced materials. As price will be a factor (the regulations are expected to "add hundreds of euros to the cost of building a car"), adding much more aluminum or carbon fiber is an unlikely option. We're told the next generation won't be longer or wider than the current car, and being Europe's most popular model, VW doesn't want to make a big bet on futuristic aero, but the report says the MkVIII will "likely" have "the most aerodynamic treatment yet seen on a production vehicle," the area where lessons learned from the XL1 will truly be seen.

Skoda's next concept is a 300-mile electric SUV

If you thought Volkswagen wasn't serious about electric vehicles, think again. Its subsidiary Skoda will reveal an electric SUV concept called the Vision E at the Shanghai auto show in a few weeks. Not only is it the fourth all-electric concept shown by the VW group (following the I.D., I.D. Buzz, and Sedric), but it previews the electrified future of Skoda, which announced that it will have five pure EVs in its lineup by 2025. The Vision E is just as impressive as the company's electric ambitions, too. It boasts a roughly 310-mile range on a charge, and packs a motor that makes about 300 horsepower. The car will be capable of level 3 autonomy, which will allow it to operate autonomously on highways, in stop-and-go traffic, and to find parking spaces. Its top speed isn't amazing at around 111 mph, but it isn't a sports car. Rather, it's an "SUV coupe" similar to the BMW X6 and Mercedes-Benz GLC Coupe. As such it has a more sedan-like back. The styling is also unique with full-width headlights and foglights, and another lighting element that extends from the front fender down the doors. The only obviously Skoda styling cue is the bulge down the center of the hood. The Vision E is also similar to the X6 and GLC Coupe in other ways. Its specs are quite close to those crossovers, particularly the Mercedes. It's a few inches shorter than the GLC Coupe, but it's an inch wider. It also makes the same amount of horsepower as the entry-level X6 and outguns the Mercedes by an impressive 59 horsepower. Of course, these are figures currently only projected and hypothetical since the Vision E is a concept, but it helps us get an idea of what this vehicle is like. So far, Skoda has only released sketches of the concept. We'll have to wait until the Shanghai show to see the real thing. Related Video:

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.
