Volkswagen's 261-mpg hand-built XL1 headed for Geneva

After years of rumors, development and testing, the Volkswagen XL1 is finally about to become a reality. The project that began life as a daring 1-Liter concept car in 2002, will finally get its production-ready curtain call at the Geneva Motor Show in just a few weeks.
As soon as it hits the streets, the two-seat XL1 will instantly become the most fuel-efficient and most aerodynamic production car in the world. The car uses a plug-in hybrid system to achieve mind-blowing consumption of just 0.9 liters of diesel fuel consumed every 100 kilometers (and average of roughly 261 miles per gallon). Plus, the XL1 can go up to 50 kilometers on its battery power alone. Coefficient of drag is a miniscule 0.189, thanks to a tiny frontal area and an obviously slippery shape.
XL1 power comes from a two-cylinder diesel motor connected to a seven-speed dual-clutch gearbox, while the 20 kW electric motor is fed by a lithium-ion battery. Both combine to give the XL1 performance figures that are, while not stirring, not shabby considering its extreme frugality: 0-62 miles per hour comes up in 12.7 seconds and top speed is nearly 146 mph.

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.

Volkswagen's emissions deception brings more scrutiny to entire industry

Volkswagen's emissions deceptions have hurt the entire auto industry's credibility with federal regulators. Days after the world's largest automaker confessed to installing software that circumvents emissions standards on approximately a half-million diesel vehicles in the United States, a top federal safety official says the company's dishonesty will force government officials to view the entire auto industry with heightened skepticism. "Your first question has to be, 'How extensive is it through the whole industry?' You don't know if it's a unique case or if other people are doing it," said Mark Rosekind, administrator of the National Highway Traffic Safety Administration. "The unfortunate part is you're not going to worry about one person. It's extended to the entire industry. If they did it, someone else could do it." "They tell you one thing, you question it." - Mark Rosekind Rosekind's agency doesn't bear responsibility in investigating the emissions cheating. That falls to the Environmental Protection Agency, which served Volkswagen with a Notice of Violation on Friday that alleged the company's diesel vehicle equipped with 2.0-liter engines contained a defeat device that allowed the cars to detect when emissions testing was taking place. In normal driving situations, the cars spewed pollution at as much as 40 times allowable thresholds. But because of the emissions cheating, NHTSA wonders if the German automaker has been cutting corners on safety standards or disingenuous on safety-related discussions. Speaking at an auto-industry event in Novi, MI, on Tuesday, Rosekind indicated no information can now be taken at face value. He used the phrase "Question assumptions" several times in discussing the case. "Of course, question assumptions means, 'Is there some other safety element there that we're now going to have to investigate?" he said. As it did in the General Motors ignition-switch probe, the Department of Justice has initiated an investigation of Volkswagen and the House Committee on Energy and Commerce announced it will hold hearings on the cheating. For NHTSA, criminal cases complicate matters. The agency core function is to regulate safety, not conduct criminal investigations. But in the early going, their investigators may be the first ones to spot wrongdoing.
