VW's diesel problems could end in criminal prosecution

It's not just auto industry insiders who are re-evaluating their thoughts on VW's diesel line-up following last week's bombshell accusation that the German automaker willfully installed software in almost a half-million diesel vehicles sold in the US to get around government emissions tests. Things are moving fast in what is already being called "dieselgate," but here are some of the big news items that we've learned since VW CEO Martin Winterkorn issued an apology yesterday. The biggest news is that both the US and German governments are looking into criminal prosecutions. Here, the US Justice Department has started a criminal investigation and Germany said that its Federal Motor Transport Authority will get involved. When the full history about all of this is written, two key players will be John German and Peter Mock from the International Council on Clean Transportation. They were the researchers responsible for actually calculating the emissions, and thus discovered that what was coming out of the tailpipe and what VW was telling the EPA did not match up. Once the EPA understood what was going on, it forced VW to either explain things all of its 2016 models would not receive certification. Sales of all VW diesels in the US have indeed been stopped, and the EPA says it will take a closer look at all light-duty diesel vehicles in the US. The re-engineered 2016 Volkswagen Passat is being launched in New York today. Two senior Volkswagen executives who were supposed to attend the event - Heinz-Jakob Neusser, VW's board member in charge of technical development and Herbert Diess, chairman of the VW brand's management board - have cancelled. An Audi vehicle is among the VW Group's vehicles affected by this issue, the A3 TDI. Given that VW has admitted in some fashion to installing the "defeat device" to get around the emissions tests, Audi's slogan "Truth In Engineering" now sounds less than perfect. Yes, there is already talk of class-action lawsuits. Nothing official is out yet, but expect to hear more about this in the near future.

2019 Volkswagen Jetta GLI vs. sport compact sedans: How they compare on paper

Hot hatchbacks may be stealing the headlines, but they're not the only way to get cheap speed. There are actually a number of small sporty sedans on the market, too, in case you want that more formal roofline. The recently revealed 2019 Volkswagen Jetta GLI highlighted these vehicles, so we figured we'd take a look at the specifications and see how they compare to each other. Our contenders are the aforementioned VW, along with the 2019 Honda Civic Si, 2019 Subaru WRX and 2019 Hyundai Elantra Sport. All four start under $30,000 and offer more than 200 horsepower. And of course, they all have trunks. In our comparison, we'll look at each car's powertrain comparing horsepower and torque. We'll also look at practicalities such as interior space, fuel economy and pricing. You can see the raw numbers in the chart below, followed by additional analysis and links to reviews. If you'd like to compare any of these cars with a different group, be sure to check out our car comparison tool. Engines and drivetrains Performance, and particularly power, is likely a priority for a sporty sedan buyer, and there's a clear leader: the Subaru WRX. At 268 horsepower, it's 40 ponies ahead of the next most potent car, the 228-horsepower Jetta GLI. It also ties the GLI for torque at 258 pound-feet. Both cars also support the old adage that "there's no replacement for displacement," since each have 2.0-liter engines while the Hyundai has a 1.6-liter unit and the Honda engine only displaces 1.5 liters. The Hyundai and Honda are nearly tied for power and torque, too, at roughly 200 horsepower and 195 pound-feet of torque. Another bonus for the Subaru is its standard all-wheel-drive system, which is handy for power delivery, lateral grip and for inclement weather. While the Jetta GLI and Civic Si are front-drive only, they do feature mechanical limited-slip differentials to enhance traction under power. The Elantra Sport makes do with electronic aids and an open differential. We're pleased that all four of these cars offer manual transmissions, too. But if you do want or need an automatic transmission, the VW, Subaru and Hyundai have you covered. The VW and Hyundai rely on seven-speed dual-clutch transmissions, and the Subaru uses a CVT with eight preset ratios for manual mode shifting. The Civic Si, though, is manual only (and it's an excellent manual at that).

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.
