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.

Recharge Wrap-up: meet the '66 ZelectricBug, DOE announces home-scale H2 refueling competition

The US Department of Energy has launched the $1 million H2 Refuel H-Prize competition to create small- to medium-scale hydrogen refueling systems. The systems could be home-scale systems that produce hydrogen using utilities at home for refueling, or medium-scale systems to supply locations such as retail centers, apartment complexes or small fleets. The DOE sees hydrogen fueling infrastructure as the biggest obstacle to fuel-cell vehicle adoption and putting the production and refueling in the hands of the consumer could be a way around that obstacle. Read more at Energy.gov and at Green Car Congress. Hyundai has announced a new six-speed automatic transmission with integrated electric motor for new hybrid models. The new configuration puts most of the hybrid powertrain components within the transmission, and the torque converter has been eliminated. The new engine clutch reduces drag with fewer clutch discs, and the mechanical oil pump has been replaced with an electric one. The result is fewer energy losses, improved efficiency and greater mileage. Read more at Hybrid Cars in Reuters or in the press release from Hyundai below. Zelectric Motors has completed its electric 1966 Volkswagen Beetle rebuild, and has put it up for sale. The '66 ZelectricBug, as it's called, is powered by a 50-kW electric motor and 20-kWh battery pack, and offers 120 pound-feet of torque. It has a range of 80 miles, and is capable of at least 100 mph. The stock transmission has been rebuilt. It also has some new goodies like high-performance sway bars, custom shocks, and LED lighting. The '66 ZelectricBug is priced at $45,000. Check it out in the video below and read more at Hybrid Cars. A startup called Alevo says it will build a billion-dollar factory in North Carolina to make longer-lasting lithium iron phosphate batteries. Alevo has purchased an old cigarette factory in Concord for $68.5 million, but it's unclear whether or not the company has secured the $1 billion investment to begin producing batteries. The company plans to create 2,500 to 6,000 jobs and produce several gigawatts worth of batteries per year, which is a tall order for a relatively unknown company. Read more at Gigaom, or in Alevo's press release below. Tesla owners in Shanghai will be exempt from the city's $12,000 registration fee. About 400 people have already received the free license plates in Shanghai, where the government wants to encourage alternative fuel vehicles.

Are more diesel scandals about to erupt?

More automakers may soon be embroiled, like Volkswagen, in diesel emissions scandals. According to the Daily Kanban, either the International Council on Clean Transportation (ICCT) or the Deutsche Umwelthilfe (DUH) will soon announce from 10 to 15 more cases of automakers cheating national diesel emissions rules. The outlet says three of the incidents are attributed to Opel. Studies conducted by the DUH, the University of Applied Sciences in Bern, Switzerland, and the UK's Leeds University found that Opel's diesel Zafira, Corsa, and Vectra models emit more NOx than European regulations allow when tested in ways that go beyond the European testing protocol, such as when done on a four-wheel rolling road instead of a two-wheel rolling road. Opel said the accusations had no merit. Specifically on the Zafira, the DUH asked Opel about the emissions findings, and Opel said that no General Motors software contains any measures to enable cheating. Opel then tested a Zafira of its own "both on a two- and a four-wheel roller dynamometer," finding that "The emission behavior determined in each case does not differ from one another." That makes this a case of he-said-she-said for the moment. The Daily Kanban's sources say the cheating methods "range from the crude to the highly sophisticated," with those at the latter end complex enough to render Volkswagen's methods "pedestrian." As for any automakers who might be named, the matter of real-world emissions exceeding a legal limit doesn't mean a carmaker has designed systems that cheat, it might mean the company designed the car to pass a test.
