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.

2017 Audi Q7 First Drive

Automotive evolution rarely makes a great leap, instead creeping along from new model to new model at a predictable pace. Audi's new Q7, though, is like handing a Bic lighter to a Cro-Mangon man smashing rocks. In Europe the new version drops 700 pounds, almost enough to reclassify its species. Audi's fire-machine will arrive in America in early 2016, as a 2017 lighter model. We spent some time in the Swiss Alps flicking the 2017 Audi Q7. As far as revolutions go, the 2017 Q7 certainly looks new. It resembles a tall station wagon more than ever, at least in European trim. A little tweaking of the design wand has left the rear end boxy and angular. Our test models use an adaptive air suspension, and the the "all-road" setting lifts the Q7 about an inch, to the normal ride height for US models. Thus raised, the big Q looks more like an SUV. This Q7 represents the first of the Volkswagen Group's MLB-platform cars. Lighter and said to be more dynamic, MLB will underpin everything from the next-gen A4 to performance and luxury SUVs like the Porsche Cayenne, and Bentley Bentayga. With the structural improvements comes a diet heavy in aluminum, the prime reason for the previously-mentioned weight savings. When outfitted for our content and crash-safety specification, US-bound models will still be about 500 pounds lighter than before. But dramatic weight-savings isn't the Q7's only trick. The adaptive air suspension significantly changes the character of the Q7, especially in the sportiest Dynamic model. There's an optional all-wheel steering feature that improves turning radius, and helps with high-speed stability. This is not to be confused with Audi's Quattro all-wheel drive, which along with a panoramic sunroof and seven seats, comes standard on all stateside models. Under the hood, things aren't so different. Both available engines are reworked but largely the same. The supercharged 3.0-liter gas engine still makes 333 horsepower and 325 pound-feet of torque, but it's not as thirsty as it used to be. Expect a two or three mile-per-gallon bump once official EPA ratings arrive. That engine, as well as Audi's reworked 3.0-liter V6 TDI – good for 260 hp and 443 lb-ft once outfitted for the US – are mated to the ubiquitous ZF eight-speed transmission. The Q7's driving character greatly depends on where it is pulling power from. While the diesel model is capable, turbo lag cuts back on the satisfaction we normally derive from oil burners.

Mercedes considering Audi Allroad rival

The Audi Allroad is something of an anomaly in the automotive world. Its competitors are limited to the recently released Volvo V60 Cross Country and perhaps the far cheaper Subaru Outback. The lifted premium wagon hasn't exactly done great for Audi, only selling a few hundred examples each month. Its best sales year was 2013, and even then, only 5,300 left US showrooms. Despite these limited prospects, word from Australia is that Mercedes-Benz is looking at launching its own competitor to the Allroad. "We are looking at every single niche, so we are studying this [Allroad] at the moment, but it is not confirmed," Matthias Luhrs, VP of sales and a member of the product management at MB, told Motoring.com.au. "We are looking obviously at C-Class and E-Class, but no confirmation at the moment." Fortunately, Luhrs recognizes that the Allroad isn't exactly a smash in the US. "In the US, no matter how long, short, high ... they don't like station wagons," Luhrs said, while adding that the Allroad concept is "developing quite successfully" in Italy and southern Europe. And for those hoping for a lifted C- or E-Class sedan, Luhrs also put the kibosh on that, saying, "We are not studying that." So what does this tell us? Well, it's still far from a sure thing that Mercedes will launch a lifted C-Class or E-Class Estate. And even if the company does go ahead with it, like the rest of the brand's long roofs (E-Class aside), don't expect to see it on US roads.
