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.

An inside look at VW's new California R&D center

Less than two months ago, the Volkswagen Group opened a new facility in Oxnard, California (about an hour's drive west of Los Angeles). The $27 million investment, touted as Test Center California (TCC), serves as a research and development lab testing emissions for all brands under Volkswagen's umbrella, including its newest member, Porsche. While still not fully operational, we toured the new 64,000-square-foot building last week and had a first-hand opportunity to see just how much work is involved testing engines and meeting increasingly stringent government emissions standards.
Replacing a similar facility established in 1990 in Westlake Village (about 20-minutes east of the new location), our guide explained how Oxnard was chosen for its temperate climate, varied regional terrain for test drives and low altitude. (The area is only a few feet above sea level - a critical parameter when instrument testing emissions.) The new facility is capable of analyzing hundreds of vehicles, prototypes and customer-owned vehicles, annually.
Most interesting to us was the huge stainless steel climate chamber, with a massive four-wheel dynamometer that allows VW to test running vehicles in both scorching desert and freezing climates without ever leaving the building (an Audi Q7 was running in place during our visit). We were also mesmerized by the countless storage tanks and intricate plumbing of chemicals, stored in both liquid and gas states, needed to perform the variety of tests. Lastly, we took a look at Bugatti's service center on the west coast, located completely within the new center. While there were no supercars on site, the facility is equipped with plenty of spare forged wheels (mounted with expensive Michelin PAX tires) and a Veyron-specific repair jig that allows the vehicle to be completely disassembled, if needed. It is a shame that the facility, which set off all of our automotive geek alerts, is closed to the public.

VW budget sub-brand stuck in limbo over VW standards, costs

Reports in October 2012 claimed Volkswagen had begun investigating the creation of its own budget brand. This came after having failed to purchase Malaysian car company Proton or produce a meaningful partnership with Suzuki, and after watching Renault-Nissan make piles of euro on Dacia and plot the return of Datsun. For VW, more important than the question of what to call it was how to build it profitably and in a way that didn't damage the VW brand. According to a report in Autocar, a satisfactory answer still hasn't been found. The hurdle is how to hit "'necessary' quality and safety levels" at the price points needed to make the venture worthwhile. At the time of the 2012 report, German outlet Der Spiegel said VW was trying to get prices down to 6,000 to 8,000 euro ($7,784 to $10,379 US), about two thousand to four thousand euro under the price of the VW Up and in line with the cost of a 6,790-euro Dacia Sandero in Germany. In March 2013, VW announced, "We want to bring a true budget car to the market in China in the foreseeable future," the most concrete move in that direction after years of planning to make a decision. Working with local Chinese maker FAW, it was predicted that the vehicle in question would appear around 2016, but as of November last year a final vote on it needed to wait until this year because "We are still working on the cost side" and profit possibilities for a car that "has to be durable, it has to be precise, it has to be safe." Even Fiat, another automaker long considering a budget brand beneath its Fiat line-up, wasn't sure how to squeeze any extra money from lower-cost products but was sure that it couldn't be done by manufacturing in Europe. If VW hasn't yet made the math work with a joint venture in China, it will be interesting to see how it might build a European go-it-alone business case.
