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.

Volkswagen CEO Martin Winterkorn resigns amid diesel scandal

Volkswagen CEO Martin Winterkorn is stepping down amid charges the company manipulated its diesel-powered cars to meet emissions regulations around the world, the automaker announced Wednesday. No successor was immediately announced, though recommendations will be made at VW's board meeting Friday. Winterkorn, 68, has led VW since 2007 and oversaw the German automaker's staggering growth around the world. His departure comes less than a week after the EPA alleged the company has been cheating on diesel emissions testing for years, and that its cars might emit 40 times more pollution than legally allowed. The EPA says about 482,000 vehicles are affected in the United States, and VW estimates at least 11 million vehicles globally might have the software that allows the vehicles to cheat emissions regulations. "As CEO I accept responsibility for the irregularities that have been found in diesel engines and have therefore requested the Supervisory Board to agree on terminating my function as CEO of the Volkswagen Group," Winterkorn said in a statement. "I am doing this in the interests of the company even though I am not aware of any wrongdoing on my part. "Volkswagen needs a fresh start – also in terms of personnel. I am clearing the way for this fresh start with my resignation." Winterkorn stepped down after an executive committee meeting of the VW Supervisory Board Wednesday. The committee agreed Winterkorn had no knowledge of wrongdoing. "The executive committee has tremendous respect for his willingness to nevertheless assume responsibility and, in so doing, to send a strong signal both internally and externally," VW said in a statement. Volkswagen is conducting an internal review and expects more "personnel consequences" in the coming days. It also will voluntarily submit a complaint to the state prosecutor's office in Brunswick, Germany, and cooperate with the expected criminal investigation. Winterkorn's departure is the latest development in VW's burgeoning diesel emissions scandal. It came to light last week after the work of researchers at West Virginia University detailed the software manipulation designed to skirt EPA tests, and it has resounded as governments around the world examine Volkswagen's diesel vehicles. The company set aside $7.3 billion to deal with the fallout and has retained the law firm that defended BP during its oil spill.

Volkswagen preparing Tiguan Coupe R

Volkswagen has might proliferation plans for the SUV side of the VW brand, Autocar listing a range that will comprise seven models and variants on sale by 2018. The next-generation Tiguan will play a large part in tripling VW's crossover lineup, a development discussed a year ago, with a standard model, the three-row long-wheelbase version to be built in Mexico, and a five-door "Coupe" variant that will get an R version worked up by the in-house R team. The Tiguan Coupe R is aimed at the performance end of the compact crossover field, giddyup coming from a 2.0-liter four-cylinder with something like 300 horsepower and 280 pound-feet of torque that works through a six-speed dual-clutch transmission. Underpinnings are expected to be cribbed from the Golf R; a hotter suspension tune with a lower ride height and four-mode damping. The sprint to 62 miles per hour would clock in around 5.1 seconds, and handling nous would be aided by all-wheel drive and electronic torque vectoring. It will need all of that in order to catch up to the competitive set listed by Autocar of the 375-hp Mercedes-AMG GLA45, 309-hp Audi RS Q3, and potential Range Rover Evoque SVR and BMW X2 M. The CrossBlue Coupe seen in Shanghai earlier this year will provide the styling cues, we're told, with rakish glass front and back, and thick C-pillars supporting a leaner greenhouse. We'll likely see the basic Tiguan at next month's Frankfurt Motor Show, then will come the long-wheelbase in 2016, the regular Coupe in 2017 along with the Touareg and US-built CrossBlue, then in 2018 the Tiguan Coupe R, CrossBlue Coupe, and Nissan Juke-fighting T-Roc.
