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 to unveil diesel-electric Twin-Up! in Tokyo

We've received multiple reports that Volkswagen will be bringing a diesel-electric concept to the 2013 Tokyo Motor Show, set to take place later this month. The car, called the Twin-Up!, is based on the Up! city car, with some sources claiming this is a thinly veiled concept that will eventually enter production.
According to Automotive News Europe, the Twin-Up! will reportedly return 214 miles per gallon on the US cycle by combining an 800-cc, two-cylinder diesel and an electric motor. It will also boast plug-in capabilities, and will be able to cover 30 miles on electric power alone.
Autocar has a more complete picture of the Twin-Up!'s powertrain, though, claiming it's a modified version of the hybrid system found in the Volkswagen XL1. The Twin-Up! will get a more potent, 47-horsepower electric motor to the XL1's 27-hp unit, but will retain that car's 47-hp turbodiesel. The battery pack will also grow, from 5.5 kilowatt hours to 8.6 kWh. Both of these increases are necessary due to the increased weight of the Twin-Up! - it's some 900 pounds heavier than an XL1.

CEO says Volkswagen's buying spree is over

After adding Italian motorcycle icon Ducati to its stable and spending $5.6 billion on the rest of Porsche, Volkswagen CEO Martin Winterkorn says he's done shopping for a while.
"We have enough to do at the moment in taking our twelve brands to where we want to be," Winterkorn tells German newspaper Handelsblatt.
