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.

Winterkorn kept diesel scandal secret, letter claims

Former Volkswagen Group CEO Martin Winterkorn allegedly kept quiet for two weeks about emissions defeat devices in the company's models. US officials eventually made the automaker's deception public on September 18th. "In the conversation on 03.09.2015 with the regulator CARB (California Air Resources Board), the defeat device was admitted," an employee told Winterkorn on September 4, according to Reuters citing Germany's Bild am Sonntag. Based on this information, Winterkorn had plenty of time to admit the problem. Evidence like this letter continues to suggest top figures knew about the emissions problem. In addition, a separate Bild am Sonntag report recently claimed that an employee emailed Winterkorn in May 2014 to tell him US regulators could discover the cheating. In the lower echelons of the company, the deception was allegedly an open secret among engineers as early as 2006, and people kept quiet even after workers tried to admit what was happening. This culture of secrecy seems to go even deeper than just the diesel emissions scandal. For example, engineers admitted that they cheated on CO2 tests to meet the company's strict standards. According to Green Car Reports, these problems also affected the US. In 2004, an Audi worker in America allegedly discovered an issue with the exhaust gas temperature sensor in some vehicles, but a German executive said not to admit the problem to US regulators. It's not clear whether any high level employees tried to fix the diesel emissions issue or if they simply kept the problem hidden. The company's internal report, which is due in the latter half of April, might address that concern. So far, the VW Group has said only a small group of people caused the scandal. However, these many allegations to the contrary make that claim difficult to believe. Related Video:

VW consumer site finally gets configurator tool back

The traditional vehicle configurator is back on the Volkswagen US consumer website, and it works very well. The company now lets visitors create a virtual model to their own specs and then search for a match among dealer inventories, as is the norm from most automakers. Last summer, Volkswagen tried to break the mold with its thoroughly redesigned consumer website in the US. It sported a slick design but made the highly controversial change of removing the configurator. Instead, visitors were narrowing their selection from a searchable database of models already at dealers. While the streamlined approach immediately told users if their desired car was available, the system also largely hid the prices for options and packages. The newly tweaked design retains the previous tablet-oriented layout, but after clicking a model, the site immediately offers "Build Yours." From there, visitors select a trim, and then the vehicle pops up with options to choose things like colors and packages. The whole layout is clean, features large buttons and works quickly. At the summary page, there's still the opportunity to search for the user's choice in dealer inventories. This is definitely a major improvement.
