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.

Audi works on AI with this mini Q2 that can park itself

Audi created a special Q2 that possesses the ability to find parking spaces, drive to them, and park itself. However, you won't be able to ride in it yet, because it's rather small. The Q2 is actually a 1/8-scale electric-powered model of the compact crossover, but the technology inside should eventually scale up. The model features just two mono cameras, one facing forward and the other rearward and 10 ultrasonic sensors around the body. According to Audi, the on-board computer uses information from all of these sources to figure out where the parking space is, and what maneuvers are necessary to enter it. The Q2 uses trial and error to improve how it parks. Audi will explain this Q2 and its artificial intelligence technology at a conference in Barcelona, Spain, this week. According to Audi, the subsidiary that created this model, Audi Electronics Venture, will transfer the tech to a full-size car in the next step of the project. With cars that can parallel park autonomously, and drive semi-autonomously, it's not hard to imagine them piloting themselves through parking lots on their own in the near future. Related Video:

Best and worst car brands of 2022 according to Consumer Reports

It's that time again, Consumer Reports this morning lifting the curtain on its 2022 Annual Car Brand rankings and its 10 Top Picks in the car, crossover, and truck category. Drumroll, please: This year, Subaru climbs two spots to claim the winner's circle, having come third the last two years. Last year, Mazda climbed three spots from 2020 to take the crown. This year, Mazda slipped to second, BMW taking the last spot on the podium, also a one-spot drop from 2021. Six automakers in the top 10 hailed from Japan, which is one more than last year, and five luxury makers occupied the top 10, which is two more than last year. And South Korean representation didn't crack the top this year, after Hyundai managed tenth last year. The seven makes after BMW are: Honda, Lexus, Audi, Porsche, Mini, Toyota, and Infiniti.  The magazine and testing concern says its Brand Report Card "[reveals] which automakers are producing the most well-performing, safe, and reliable vehicles based on CR’s independent testing and member surveys," and that "Brands that rise to the top tend to have the most consistent performance across their model lineups." The domestics also took steps back among the 32 OEMs ranked on the 2022 card. Chrysler and Buick were the domestic carmakers who made last year's top 10 in eighth and ninth, respectively. This year, Buick dropped to eleventh, Chrysler to thirteenth. Dodge went from fourteenth to sixteenth. CR continues to ding Tesla's yoke steerer, the not-exactly-natural handhold responsible for the electric carmaker going from sixteenth last year to twenty-third this year.
