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 to blitz 1.5M sales goal two years ahead of schedule

Audi doesn't seem to be having any trouble of hitting its relatively audacious sales goal of two million units by 2020 - it's already on pace to eclipse 1.5 million sales two years ahead of schedule. According to Reuters, the Volkswagen-owned brand rode a wave of sales in China and the US to pace the early goal, with 780,500 deliveries at the halfway point of 2013. Particularly hot models include the Q5 crossover seen above and A4 sedan. Unless things go poorly in the second half of the year, 1.5 million sales shouldn't be an issue.
That leaves it trailing BMW by just 24,000 units for the global luxury sales crown. If sales trends keep up, Audi will succeed in hitting its goal of two million units and besting its cross-country rival in Munich. Audi CEO Rupert Stadler smells blood, telling German newspaper Handelsblatt, ''We have overtaken Mercedes-Benz and we are now closer to BMW than ever before."

Audi reveals updated RS7 Sportback in Europe

It was just a couple of weeks ago that Audi revealed a few mild updates to its A7. It even ported those changes over to the warmed-up S7 performance version. All that was missing was the full-steam RS7, and that's precisely what we have here.
Now before you get all excited, note that the new RS7 packs the same powertrain as the model it succeeds, but then again, the existing RS7 hardly lacked in the power department. The 4.0-liter twin-turbo V8 still churns out 560 horsepower and 516 pound-feet of torque, transmitted to all four wheels through an eight-speed automatic. Revealed initially for the European market (with US details presumably to follow), the 0-62 kilometers per hour time is quoted at 3.9 seconds, so the 0-60 mph time ought to match the 3.7 seconds of the preceding model.
What has changed are the subtle tweaks Audi has made to the exterior and equipment upgrades inside. The grille now features has a horizontal section at the bottom with the Quattro logo emblazoned across like all other recently revised RS models, flanked by new headlights (Matrix LED units for the European market). Inside the cabin the air-con vents and shift paddles have been reshaped, and the new MMI system ports over from the new A7 and S7 with 4G LTE connectivity and a Bang & Olufsen sound system.
