CARB has 20 days to confirm VW's 3.0-liter TDI emission fix

VW's diesel scandal has been in the headlines since last September, but solving the problem it proving difficult. Volkswagen Group has submitted a proposal to the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA) to fix about 85,000 vehicles with the 3.0-liter diesel V6 in the US, Reuters reports. CARB now has 20 business days to test if the plan actually reduces emissions. If accepted, VW could finally begin a recall and end the stop sale on vehicles with these engines. In a statement, CARB pledged to, "respond following a thorough and complete review to make sure the plan addresses the presence of the illegal defeat device and follows the necessary environmental, vehicle and public health and safety regulations." Neither CARB nor the EPA outlined the proposed repairs, but Porsche CEO Oliver Blume already suggested the fix for the engine in the diesel Cayenne. Examples from 2013 and 2014 allegedly need a new catalytic converter and software update, and those from 2015 and 2016 only need the improved code. It's not yet clear whether this procedure would work for all models with the 3.0 TDI. While the EPA issued the notice of violation against VW's 2.0-liter four-cylinder diesel in September, the first one for the 3.0-liter V6 came in early November. By the end of the month, the agency broadened the scope to about 85,000 vehicles, including some examples of the VW Touareg, Audi A6, A7, A8, Q5, Q7, and Porsche Cayenne. The affected companies issued stop sales on new models with the engine. Audi eventually admitted to regulators that it didn't disclose three auxiliary emission control devices in the powerplant's code and promised to develop a software update to fix the problem. CARB gave the automaker 45 business days to submit the proposed solution. If accepted, this repair would allow VW Group to end part of the emissions scandal, but there's no guarantee the regulators consent to this solution. Just a few weeks ago, CARB looked at the automaker's plan to fix the 2.0-liter TDI and rejected it, claiming a lack of detail.

Audi will submit emissions fix for 3.0 TDI V6 to EPA and CARB

Audi will develop a software update for the emissions control system on Volkswagen Group's 3.0 TDI V6 and will submit the changes to the Environmental Protection Agency and California Air Resources Board for approval. If the government regulators accept it, the tweaks could end the emissions problems for an estimated 85,000 of these engines in the US in Audi, Porsche, and VW models. However, the stop-sale still covers these vehicles until further notice. Audi admits in its statement to failing to disclose three "auxiliary emission control devices" on the V6 to regulators, and US law considers one of these systems a defeat device. VW Group offered the engine in the US on the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year. The mill was also available on the VW Touareg and Porsche Cayenne. The EPA filed a violation against the 3.0 TDI on November 2 because the agency reported that the engine's software contained a defeat device to circumvent emissions tests. The regulator recently extended that notice to cover these powerplants in the US from the 2009 to 2016 model years. Audi's statement vaguely estimates the price of this problem to be in the "mid-double-digit millions of euros," and the automaker could face financial punishment by regulators. "Determinations regarding potential penalties and other remedies will be assessed as part of the investigation EPA has opened in conjunction with the US Department of Justice," an EPA spokesperson told Automotive News.

That is the result of the discussions held between a delegation from AUDI AG and the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). The updated software will be installed as soon as it is approved by the authorities. The three brands Audi, Porsche and Volkswagen are affected. Audi estimates that the related expense will be in the mid-double-digit millions of euros.

5 stars in Euro NCAP crash tests for 5 new cars available in U.S.

Seven new cars have received a full five-star rating in the latest Euro NCAP crash tests. Of these, five are available in the United States: the Audi E-Tron, Lexus UX, Toyota Corolla, RAV4 and Mazda3. The Renault Clio and the Volkswagen T-Cross also took part, also receiving five stars. The Mazda3 hatchback was the fourth car in Euro NCAP history to reach an adult occupant protection score of 98%, after the Volvo V40 and XC60 and the Alfa Romeo Giulia. No NHTSA ratings for the Mazda3 or the Audi are yet available, but the Lexus and the Toyotas have all received five-star NHTSA safety ratings as well. Those three were tested as hybrid variants by Euro NCAP. Audi's first fully electric vehicle, the E-Tron, scored 91% in Euro NCAP's adult occupant rating, with unavailable knee airbags bringing down the score. The Mazda and the Toyotas offer them for the driver only, and the Lexus has the passenger's knees covered as well. The Lexus UX managed a 96% adult occupant score, close to the Mazda, and it provided better pedestrian safety (82%) than the Audi (71%), despite neither, or none, of the test vehicles having an active hood to catch pedestrians. As for the Toyotas, the Corolla, tested in both sedan and hatchback guises, scored 95% for adult occupant safety, with the RAV4 a couple notches down at 93%. Still, the five-star rating means all these vehicles are a very safe choice in their respective classes. Michiel van Ratingen, secretary general of Euro NCAP, states how important it is that even family hatchbacks perform well and have the latest safety tech available. "It is encouraging to see that all manufacturers did well, regardless of type of powertrain or class of vehicle tested," said van Ratingen. "New cars on the market continue to offer more advanced technology as standard, systems that were not even considered an option a few years ago." More crash test videos are available on Euro NCAP's YouTube channel. Audi Lexus Mazda Toyota Car Buying Safety audi etron lexus ux
