Volkswagen finds CO2 'irregularities' for 800k vehicles

The latest issue for Volkswagen affects another 800,000 vehicles, and this time its for irregularities in CO2 emissions certifications. VW estimates this issue could cost the company $2.2 billion to fix. The company officially makes no specific mention of which engines are covered, the models they are in, or even where they are located. VW discovered the situation during its ongoing internal investigation, and, according to the automaker, "it was established that the CO2 levels and thus the fuel consumption figures for some models were set too low during the CO2 certification process." Most of the affected vehicles are diesels, and the company is now reaching out to "the responsible type approval agencies" to figure out the next step. While VW isn't officially confirming which models and engines are involved, Automotive News reports that it affects some 2012 and later VW, Audi, Seat, and Skoda models with the company's 1.4-, 1.6-, and 2.0-liter diesel engines, as well as the 1.4-liter ACT gasoline engine. The issue mainly affects vehicles sold in Europe. "The Board of Management of Volkswagen AG deeply regrets this situation and wishes to underscore its determination to systematically continue along the present path of clarification and transparency," CEO Matthias Muller said in the announcement. Volkswagen Group of America spokesperson Jeannine Ginivan was able to provide some further clarification to Autoblog. "This is not related to US-certified vehicles," she said. Clarification moving forward: internal investigations at Volkswagen identify irregularities in CO2 levels Matthias Muller: "Relentless and comprehensive clarification is our only alternative." Around 800,000 Group vehicles could be affected Initial estimate puts economic risks at approximately 2 billion euros The Volkswagen Group is moving forward with the clarification of the diesel issue: during the course of internal investigations irregularities were found when determining type approval CO2 levels. Based on present knowledge around 800,000 vehicles from the Volkswagen Group could be affected. An initial estimate puts the economic risks at approximately two billion euros. The Board of Management of Volkswagen AG will immediately start a dialog with the responsible type approval agencies regarding the consequences of these findings. This should lead to a reliable assessment of the legal, and the subsequent economic consequences of this not yet fully explained issue.

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.

Does faster charging make you want an Audi Q7 PHEV?

Don't let the image of a heavy diesel-powered plug-in hybrid SUV fool you. The Audi Q7 E-Tron will be a quick thing when it goes on sale in Europe this summer. And the SUV will be able to be recharged at a pretty good clip as well, says Automotive News Europe. A full charge of the Q7 E-Tron can provide a range of as much as 35 miles in all-electric mode, using lenient European specifications. One of the model's bells and whistles will be battery-recharging technology that allows the SUV to be recharged at up to 7.2 kilowatts. That means that the battery can be fully recharged in about two and a half hours. Not exactly Tesla Supercharger territory, but not bad. How much a faster recharging option impacts demand for a plug-in vehicle is open to interpretation. For instance, an Idaho National Laboratory study released late last year estimated that about 85 percent of the recharging activity for the Chevrolet Volt extended-range plug-in and Nissan Leaf EV happened at home, implying that how long it takes your plug-in to fill up may not be a huge factor. So, how much would this option of faster recharging sway your decision in buying a plug-in hybrid? The Q7 E-Tron's V6 diesel engine and electric motor, which operate in a parallel hybrid setup, combine to deliver 373 horsepower and 516 pound-feet of torque. That combination can propel the SUV from 0 to 60 miles per hour in about six seconds. Of course, test that out a few times, and your all-electric range is likely to drop a bit. Audi is expanding its batch of E-Tron plug-in vehicles to better compete with German brethren BMW and Mercedes-Benz. Audi's first E-Tron, the A3, sold almost 12,000 units in Europe last year, about the same as BMW's all-electric and range-extender variants of the i3 in Europe combined, Automotive News says, citing JATO Dynamics. Audi will debut its Q5 E-Tron later this year and the A8 E-Tron in 2017. The Q7 E-Tron will be priced at about $88,000 in Europe. As for US sales of that model, questions remain about whether the SUV will have a diesel or gas-powered engine paired with the electric motor, but Americans should start getting access to it in either 2017 or 2018.
