EPA message to automakers: You're on notice

With top administrator Gina McCarthy speaking about the "moral obligation for climate action" on Friday, the Environmental Protection Agency announced it would ramp up its oversight of the auto industry in the wake of Volkswagen's emissions cheating. In a letter sent to manufacturers Friday, the agency said it would begin examining cars to see whether they contained defeat devices "in addition to the standard emissions test cycles." "We are putting vehicle manufacturers on notice." Exactly how the agency plans to test for these devices – which are not devices per se, but algorithms contained in millions of lines of software code that govern vehicle functions – remains unclear. Christopher Grundler, the director of the EPA Office of Transportation and Air Quality, divulged few details in how the agency would uncover so-called defeat devices used by cheaters. "Not today – or actually ever – I'm not going to be describing what new ways we'll be using to detect these defeat devices." Later, he said engineers will have to "come up with some clever ways to do this." The only insight he offered was that the EPA, California Air Resources Board, and Environment Canada would partner on testing more cars for emissions and anomalies. Grundler also said the EPA would diversify its testing fleet. In addition to relying on vehicles provided by manufacturers, the federal agency will now also borrow cars from "private citizens" and utilize rental cars for tests. "We are putting vehicle manufacturers on notice," he said. Joint investigations between EPA and CARB have "been very successful in protecting human health and the environment," said Janet McCabe, the agency's acting administrator in the Office of Air and Radiation. "But we also know, and the Volkswagen violations before us now make it clear, we need to adapt and step up our oversight." That may include an increase in on-road testing in addition to the five emissions tests now more relied upon. The EPA owns and maintains 23 portable emissions-monitoring systems like the one used by West Virginia University researchers who first detected elevated levels of nitrogen oxide emissions from two Volkswagen diesel vehicles. Right now, they're almost exclusively deployed to monitor emission from heavy-duty vehicles, whose NOx emissions "dwarf" the amount produced by light-duty vehicles, which produce less than 2 percent of the total, according to the agency's figures.

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.

Editors' Picks March 2022 | Acura RDX, VW GLI and a Rolls-Royce

This month's Editors' Picks offer a little something at every budget. We call out a performance car as cheap as the Volkswagen GLI, but the Rolls-Royce Ghost also manages to make its way on to the list. Of course, very few folks can afford a Ghost, but that doesn't change the fact that it's an engineering master class. In addition to these options, we also dive into the compact luxury SUV market, one that is bursting with choices. In case you missed our previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in March that earned an EditorsÂ’ Pick. 2022 Acura RDX Quick take: The RDX ticks a lot of boxes for a great price. It drives better than expected, offers excellent tech, has plenty of room and even looks the part. Score: 7.0 What it competes with: Mercedes-Benz GLC-Class, BMW X3, Volvo XC60, Audi Q5, Lexus NX, Infiniti QX50, Alfa Romeo Stelvio, Genesis GV70, Porsche Macan, Jaguar F-Pace, Lincoln Corsair Pros: Value, driving dynamics, space Cons: Infotainment is polarizing, midgrade interior From the editors Road Test Editor Zac Palmer — "The RDX is a bit of a sleeper in this segment. It drives far better than many of its competitors, and it doesn't let you down in any particular area. If you were thinking of buying an entry-level option from one of the Germans, make sure you take the RDX into account, because you'll likely end up with more tech and features for an even lower price. News Editor Joel Stocksdale — "The Acura RDX is an impressive value in the small luxury SUV segment. It starts in the low $40,000 price range, and provides loads of standard convenience and safety features. Everything is packaged in a sharp and surprisingly spacious package, too. It's also nimble and has a punchy engine that makes it fun to drive. You may find some competitors that surpass it in some areas, but the Acura offers about the most for the money of anything in the segment."
