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's CEO might not have known of VW emissions scheme

There's been no shortage of finger-pointing when it comes to finding people to blame for the Volkswagen diesel-emissions scandal that broke last September. One rather powerful executive, however, appears to have escaped blame. That would be Audi CEO Rupert Stadler, whose company sold about 85,000 diesel vehicles with emissions-cheating software, Reuters says, citing people familiar with the process. US law firm Jones Day questioned executives at both VW and its Audi unit and has found no evidence that Stadler was complicit with the plan, which involved programming Volkswagen-made diesel engines to produce artificially low emissions when the vehicle was being smog-tested. In Audi's case, the engine type in question was the 3.0-liter V6 diesel. Officials with both VW and its Audi unit declined to comment, according to Reuters. That engine was used for the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year, in addition to the VW Touareg and Porsche Cayenne. Audi also sold the VW Group 2.0-liter four-cylinder in the A3 from 2010 to 2013 and 2015. VW has reached an agreement with US regulators concerning that engine, which is also not connected to Stadler. Last month, German newspaper Bild am Sonntag published specifics on how the 3.0-liter diesel cheated the emissions-testing process, including records that the motor was programmed to shut of its emissions-control equipment after 22 minutes of running, or about two minutes longer than typical emissions-compliance testing. Audi said last November that it would work on a software update for the V6's emissions-control system that would be submitted to both the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA), but the VW unit hasn't reached any settlement with US regulators implying that a solution was agreed upon. Volkswagen's settlement with the EPA will cost Europe's largest automaker as much as $15 billion in the form of buybacks, lease buyouts, vehicle repairs, and investments in zero-emissions technology. VW sold about a half-million vehicles in the US that contained the so-called "cheat" software.

Audi readying 650-hp Sport Quattro Concept for Frankfurt

Remember Audi's perfectly lovely Quattro Concept from the 2010 Paris Motor Show? Of course you do. The latter-day Ur-Quattro is laser-etched in our brains as well - and not just because Audi was kind enough to offer our man Michael Harley a mountain drive of its seven-figure showcar. At the time, Audi hinted that the coupe might have a showroom future, but the gossip pipeline has long since gone dry, leading us to believe that the car's production hopes had soured.
That 2010 concept was powered by a 2.5-liter five-cylinder engine yielding 380 horsepower and 354 pound-feet of torque, a relatively modest but appropriate engine configuration in light of the Ur-Quattro's five-banger. Given the Quattro Concept's size and specs, it wasn't clear exactly where such a vehicle might fit into the company's lineup, though, as it already already offers the successful A5/S5/RS5 lineup.
Apparently, Audi might have a solution to that conundrum. A new report from Germany's AutoZeitung suggest that the automaker is posed to reveal a production version of the concept at the Frankfurt Motor Show in September - on the Ur-Quattro's 30th anniversary, no less. Word is that Audi is taking the Quattro Concept upmarket in a big way, with a tuned version of the twin-turbo 4.0-liter V8 from the RS7 churning up in the neighborhood of 650 horsepower. Naturally, all-wheel drive will get all that power to the ground, and new bodywork is expected as well. In addition to the powertrain switch-up, there is talk of extensive use of lightweight materials, including magnesium, carbon fiber and aluminum, with a target weight of under 2,900 pounds. Magnetic ride control suspension and carbon-ceramic brakes are also expected to find their way onto the model. Unsurprisingly, all of that extra equipment is likely to impact the car's bottom line - reports suggest its sticker price could crowd that of the mighty R8 at around $150,000.
