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.

2014 Volkswagen GTI to start a new hot hatch era in Geneva

The upcoming Geneva Motor Show is going to be stocked with important new production models and sexy concept cars, but hot hatch enthusiasts will undoubtedly see it as the coming out party of the MkVII Volkswagen GTI. And while we've only got European specifications and pricing to go on for now, we can tell from the get-go that the new GTI will be a proper heir to VW's hot hatch legacy.
This seventh-generation GTI is powered by a turbocharged, direct-injection 2.0-liter four-cylinder engine, which makes 220 horsepower and 258 pound-feet of torque in base form. For the first time ever, Volkswagen is also offering a performance pack for the GTI as well, which ups the horsepower to 230 (torque remains unchanged). With a slightly lower curb weight to push around - the new base car weighs 2,978 pounds versus 3,034 for the current three-door GTI - 0-62 miles per hour is now achieved in 6.5 seconds, and top speed is 153 mph. (Cars with the performance pack offer 0-62 mph in 6.4 seconds, and a 155-mph top speed.) Buyers my choose between a six-speed manual transmission or an optional six-speed DSG unit.
Visually, the new GTI has obviously adopted the slant-nosed looks of the MkVII Golf, though with plenty of added drama. The exterior is dominated by the 17-inch "Brooklyn" wheels wearing 225-section rubber, and the aggressive front fascia gets black honeycombed inserts in the upper and lower grille sections. At launch, Volkswagen will offer the GTI in three colors: the Pure White seen here, Tornado Red and Black. Tartan patterned seats are of course still an option for the interior, while the GTI-specific steering wheel and shift knob are standard.

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.
