VW orders external probe into diesel emission scandal

There are well over 480,000 Volkswagen-made, diesel-powered vehicles currently traveling roads in the United States that do not meet the Environmental Protection Agency's emissions requirements. This, as you can probably imagine, is a very big deal, and has led VW CEO Professor Doctor Martin Winterkorn to release an official statement on the matter. "I personally am deeply sorry that we have broken the trust of our customers and the public," he said. It's important to note that these vehicles run software with a so-called "defeat device" that kicks in when the on-board computer senses that it is being tested for emissions. When the car is operating normally – in other words, when its exhaust isn't being sniffed – the cars do not meet US emissions standards. According to the EPA and the California Air Resources Board, affected cars emit as much as 40 times the allowable level of certain pollutants. "We will cooperate fully with the responsible agencies, with transparency and urgency, to clearly, openly, and completely establish all of the facts of this case," according to Winterkorn, who added, "Volkswagen has ordered an external investigation of this matter." It's not yet known who will carry out this investigation. At present, there are still a number of 2015 Volkswagen models on dealer lots that do not meet emissions requirements. VW has issued a stop sale on vehicles equipped with the 2.0-liter TDI diesel engine. What's more, the German automaker has been barred from selling 2016 model-year vehicles that use this engine, according to The Detroit News. Last year, diesel vehicles made up about 22 percent of all VW sales, which means these restrictions will have a big impact on the brand's sales performance until a remedy is found and the vehicles are approved for sale. Interestingly, the EPA has started a campaign of sorts to test vehicles from other automakers that sell diesel-powered vehicles in the United States to make sure they comply with emissions requirements under all operating circumstances. The EPA says it "will be reviewing [its] compliance protocols and introducing ways in which [it] can effectively test not only for emissions performance but also for the potential presence of defeat devices," according to a statement provided to The Detroit News.

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.

Recharge Wrap-Up: Tesla, CarCharging and the EPA

Credit Suisse analysts are bullish on Tesla. The group gives the electric car company's stock an "outperform" rating with a target price of $325. For its continued success, Credit Suisse cites the vehicles' superior technology, in turn offering more torque, roominess and reliability. Says analyst Dan Galves said of Tesla's competition with ICEs, "If Tesla can get to cost-parity with Internal Combustion vehicles and still offer $1,400 to $2,500 per year fuel savings to the consumer, it won't be a fair fight."

The Tesla app is adding this functionality soon, perhaps with the update to iOS 8. It's not yet clear how this function will work, but it's one more innovative convenience feature that Model S owners can enjoy. That means drivers will have less to carry in their pockets or purses when they go for a drive. Read more at 9 to 5 Mac. CarCharging Group has remotely lowered the amperage on some of its residential users' Blink charging stations to 24 amps. This will slow down the charging time for affected customers with 6.6-kilowatt charging by about 15 percent. The company cited safety reasons for the move, with concerns about overheating. The amperage reduction is temporary, until CarCharging is able to provide replacement parts for the chargers. Some are concerned about the delayed action, as well as the fact that the reduction was handled without owner permission. Read more at Plugin Cars. Ford is halting test drives and sales of certain C-Max hybrid and Focus models due to a safety concern. Cars made during a single week this month at a Michigan factory may not have enough ball bearings in the steering gear assembly, which could lead to loss of control. None of the affected cars have been sold, Ford says, and about 50 units are currently at dealerships. Just over 600 will need to be recalled. Dealerships have been notified of the problem.

The report shows a 66-percent reduction in benzene, almost 60 percent reduction in mercury from man-made sources, 84 percent less lead and more.
