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 builds its six-millionth Quattro-equipped car

All-wheel drive has become the norm particularly among German automakers. Mercedes offers its 4Matic system on a broad range of models, BMW counters with its xDrive system, Volkswagen has 4Motion, and the only Porsche you actually can't get with all-wheel traction is the Boxster/Cayman. But before all its competitors got on board with channeling power to all four wheels, Audi was making a name for itself with its Quattro all-wheel-drive system.
Now 34 years since the advent of the original Audi Quattro, the House of the Four Rings has built its six millionth vehicle equipped with all-wheel drive - only a year and a half since it hit the five-million mark. In fact these days nearly half of all new Audis are ordered in Quattro spec - more than any other automaker - resulting in a total of 710,095 Quattro-equipped Audis produced last year alone.
The landmark 6,000,000th vehicle was an SQ5 in monsoon gray metallic that rolled off the assembly line on Friday and is bound for a customer right here in the United States.

Audi S3 Cabriolet is a topless two-door temptress

Now that we've driven the Audi S3, we're pretty eager for it go on sale in the United States. And while we won't get the Sportback version, there's a teeny tiny chance that Audi may grace us with this new Cabriolet version that makes its debut at the Geneva Motor Show this week.
That certainly wouldn't be a shame, considering the topless S3 packs the same 290 horsepower and 280 pound-feet of torque as the sedan, all of which comes from a turbocharged, 2.0-liter inline four-cylinder engine. That folding roof mechanism adds a bit of weight to the S3 package, and thus, reaching that ever-so-special 62 miles per hour takes an extra half a second - 5.4 compared to 4.9 with the S3 sedan.
Looks-wise, we dig the aggressive little S3, though the chrome wheels of the show car are kind of throwing us off. Swap out a set of standard alloys, and we'll be good to go. Have a look in the gallery above to see the topless Audi for yourself.
