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.

VW invests in QuantumScape for potentially fireproof, long-range EV batteries

VW might be getting ready to push its plug-in technology in a big way thanks to an investment in the battery startup QuantumScape. Key point: the solid-state battery is said to be fireproof and will offer tremendous range advantages. Details are not abundant yet, but according to Bloomberg, VW of America bought a five-percent stake in QuantumScape (and has an option to raise its holding). The tech could "more than triple" the EV range of VW, Porsche and Audi plug-in vehicles as soon as the middle of 2015, according to unnamed sources that Bloomberg talked to. Former Stanford University researchers started QuantumScape in 2010. The bare-bones QuantumScape website (there's nothing there other than some contact information) doesn't offer many hints about what's happening at the company, but GigaOM's Katie Fehrenbacher notes that QuantumScape is licensing tech from the "All Electron Battery" project at Stanford a few years ago. It certainly sounds amazing: [It's] a completely new class of electrical energy storage devices for electric vehicles that has the potential to provide ultra-high energy and power densities, while enabling extremely high cycle life. The All-Electron Battery stores energy by moving electrons, rather than ions, and uses electron/hole redox instead of capacitive polarization of a double-layer. ... If successful, this project will develop a completely new paradigm in energy storage for electrified vehicles that could revolutionize the electric vehicle industry.

VW recalls 25k Jettas over low-beam headlight issue

Volkswagen has discovered an issue with the headlamps on its latest Jetta and is issuing a recall notice in conjunction with the National Highway Traffic Safety Administration to correct the issue. The problem revolves around the headlight control module, which has been found in certain instances to switch off the low-beam headlights when the high beams are turned on. Needless to say, that could result in insufficient illumination in the dark, so VW is moving to update the module's software. The issue only affects the new 2015 Jetta – specifically those manufactured between July 11, 2014 (which just happens to be this writer's birthday, thank you very much) and November 13, 2014. All in all, the Volkswagen Group of America estimates that encompasses 25,007 units in the United States, the owners of which can expect to hear from their dealers in the new year. RECALL Subject : Insufficient Headlight Output Report Receipt Date: DEC 15, 2014 NHTSA Campaign Number: 14V790000 Component(s): EXTERIOR LIGHTING Potential Number of Units Affected: 25,007 All Products Associated with this Recall close VOLKSWAGEN JETTA 2015 Manufacturer: Volkswagen Group of America, Inc. SUMMARY: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2015 Jetta vehicles manufactured July 11, 2014, to November 13, 2014. Due to incorrect software within the headlight control module, the low beam headlights may turn off when high beam lights are turned on. As a result, the light output from the headlights may be insufficient. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108. "Lamps, Reflective Devices, and Associated Equipment." CONSEQUENCE: Insufficient headlight output may increase the risk of a crash. REMEDY: Volkswagen will notify owners, and dealers will update the headlight control module software, free of charge. The recall is expected to begin in January 2015. Owners may contact Volkswagen customer service at 1-800-893-5298. Volkswagen's number for this recall is 57F6. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
