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 recalling 38k Jettas, Passats, Golfs and Beetles for fuel leak

Earlier we reported on a recall issued for the 2015 VW Jetta regarding a problem with the headlights, and now Volkswagen and the National Highway Traffic Safety Administration have issued another recall for a separate issue affecting not only the Jetta, but several other models as well. The issue revolves around a sealing cap in the fuel rail, which could leak fuel into the engine compartment and potentially cause a fire. The problem affects an estimated 37,979 vehicles in the United States, including the 2014-15 Jetta (manufactured between March 28 and November 24, 2014), the 2014-15 Passat (April 7 to November 18), the 2015 Golf and GTI (July 1 to November 20) and the 2014-15 Beetle and Beetle Convertible (March 31 to November 27). That covers pretty much the entire range offered by Volkswagen of America, short of the Tiguan and Touareg crossovers (and the discontinued Eos convertible). Considering, though, that VW routinely sells around 30,000 vehicles in the US each month, the small number of vehicles being recalled (relative to the quantity out there) tells you this recall really only affects a specific cross-section of models. Owners of the affected vehicles can expect to be contacted by their dealers to have the fuel rails replaced. RECALL Subject : Fuel Leaking Into Engine Compartment Report Receipt Date: DEC 22, 2014 NHTSA Campaign Number: 14V809000 Component(s): FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 37,979 Manufacturer: Volkswagen Group of America, Inc. SUMMARY: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2014-2015 Jetta vehicles manufactured March 28, 2014, to November 24, 2014, certain 2014-2015 Passat vehicles manufactured April 7, 2014, to November 18, 2014, certain 2015 Golf and GTI vehicles manufactured July 1, 2014, to November 20, 2014, and certain 2014-2015 Beetle and Beetle Convertible vehicles manufactured March 31, 2014, to November 27, 2014. A sealing cap at the fuel rail may fail, allowing fuel to leak into the engine compartment. CONSEQUENCE: A fuel leak, in the presence of an ignition source, can result in a vehicle fire. REMEDY: Volkswagen will notify owners, and dealers will replace the fuel rails with new parts, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Volkswagen customer service at 1-800-822-8987. Volkswagen's number for this recall is 24Bi.

Car companies may need to start curbing model proliferation

Looking at the current automotive landscape, especially from German makers, you quickly get the impression that less definitely isn't more. BMW alone offers its 3 Series platform in practically every segment possible, including the regular sedan and 4 Series Gran Coupe, which would seem to be direct competitors. Porsche might be the winner, though, with 20 different variants of the 911 listed for sale on its US website. However, some of this model madness might be reaching an end as companies begin cutting back spending or shifting money to other priorities.
According to Yahoo Finance, the offerings from the German automakers are up 25 percent over the past three years to over 200 models in Europe. The peak is expected to come around 2018 at 230 separate vehicles, according to consulting company PwC.
Amazingly, BMW, which is among the poster children for this model explosion, might be changing its tune. "I'm sure there will be points in the future where we look at certain cars and say, 'Maybe we need to think differently now,'" said head of sales Ian Robertson in an interview, according to Yahoo Finance. The statement certainly sounds shocking coming from a company rumored to have 23 front-wheel-drive vehicles all using a single platform on the way.
