VW “Tip of the Iceberg” in Diesel Emissions Scandal | Autoblog Minute

Some are calling Volkswagen just the tip of the iceberg in the diesel emissions scandal. Autoblog's Adam Morath reports on this edition of Autoblog Minute. Volkswagen Autoblog Minute Videos Original Video emissions scandal

Recharge Wrap-up: Tesla Model S full speed, Pheonix EVs at LAX

A Tesla Model S driver shows what it's like to maintain about 125 miles per hour on the German Autobahn. In the video, Bjorn Nyland records his trip from a stop at a Supercharger 25 miles to the Danish border while driving about 200 kph for about 12 minutes. Upon entering the Autobahn, he hits the limiter at about 212 kph, or almost 132 mph. As he's driving, the car's estimated driving range adjusts for his speed, and he quickly loses quite a few miles. He doesn't care, though. He's having fun. See the video above, and read more at Inside EVs. Phoenix Cars has provided an Electric Shuttle Bus to an airport parking company at the Los Angeles International Airport. As LAX's first electric shuttle bus, it is expected to run two shifts seven days a week, saving more than 60 tons of CO2 emissions yearly. The electric shuttle bus will be on display from June 29 to July 2 at the International Parking Institute Conference and Expo in Las Vegas. Phoenix also recently supplied its ZEUS electric flatbed to the US Navy. Read more in the press release below. Ballard will operate a fleet of eight hydrogen-powered buses in London for an additional five years. Transport for London uses the buses, powered by Ballard fuel cell technology, for its central Covent Garden-Tower Gateway route. The first five buses went into service in 2010 as Transport for London aimed to reduce CO2 emissions by 60 percent from 1990 levels by 2025. The three additional buses joined the fleet in 2013. "This contract extension is a positive endorsement of zero-emission fuel cell technology in transit applications, based on the demonstrated performance of these buses over the past five years," says Ballard Chief Commercial Officer Steve Karaffa. "Clean transportation is a growing concern for transit authorities globally and our fuel cell modules deliver a proven solution." Read more from Ballard. Volkswagen and SAIC are expanding electric vehicle operations in China. The partners will expand the main Shanghai Volkswagen plant to build electric vehicles. "Over the next four years, we plan to localize more than 15 different electric vehicle models in China, including plug-in hybrids and fully electric vehicles," says Volkswagen's Prof. Dr. Jochem Heizmann. Volkswagen will also step up fuel cell and plug-in hybrid research in China. In about four years, Volkswagen will build a new EV, based on the popular Lavida, at the Anting plant outside of Shanghai.

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.
