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.

Someone is leaving anti-diesel flyers on Volkswagen TDIs in Portland

As if some Volkswagen TDI owners don't already feel bad enough, given the recent diesel scandal, someone is further shaming them. Flyers full of bad information are being left on TDI cars in eco-friendly Portland, OR. Portland-based sandwich joint Lardo posted a picture of the flyer to their Instagram account yesterday morning. Along with annoying font color changes, the flyer incorrectly states that the diesel car spews two to four times more pollutants than a Chevy Suburban. The author of the flyer also throws a Nazi mention in there for good measure, though they get the history wrong, too. Volkswagen wasn't founded by Nazis, though the Nazi government did create a nationalized car industry to build the 'People's Car', originally designed by Ferdinand Porsche. The factory ended up making war machines instead. Volkswagens weren't really produced until after the fall of the Nazis at the end of World War II. This content is hosted by a third party.

Once on the road, the car spewed 40 times more pollutants than it claimed. The automaker plans to 'refit' 11 million faulty vehicles. Today, the automaker launched a website dedicated to consumers unlucky enough to own the bum vehicles. Eco-warriors aren't the only ones leaving judgmental, passive-aggressive notes on cars. Like this incident in Portland, these notes often fall flat, like when this paralyzed man in Michigan parked in a handicap spot and was accused of stealing the spot simply because he drove his BMW to the gym.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.
