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.

2016 Audi S6

Minutes after spending time in the refreshed 2016 Audi A6 in Germany, we were tossed the keys to its enthusiast-tuned sibling, the Audi S6. In similar manner to its lesser brethren, the S6 has also been updated for the 2016 model year with a new look, a boost in power and additional technology.
Its aggressive demeanor is heralded by a redesigned signature single-frame grille, resculpted bumpers (front and rear) and new lights on both ends - the Matrix LED headlamps fitted to our European test car are impressive, but the US DOT has ensure that we won't see them (pun intended) for now. The cabin appointments have gone even further upscale, and the enhanced MMI infotainment system now runs more fluidly thanks to a faster NVIDIA graphics chip. The primary instrument cluster, facing the operator, has been redesigned to offer its own duplicate display to ease the driver's workload.
Under the hood, the twin-turbocharged 4.0-liter TFSI V8 is bumped to 450 horsepower (a gain of 30), while torque remains the same at 406 pound-feet. The standard gearbox is Audi's seven-speed S-tronic dual-clutch unit, sending power to all four wheels through the automaker's rear-biased Quattro permanent all-wheel-drive system.

Audi Q1 captured wearing production metal for first time

Audi is getting closer and closer to introducing its smallest crossover ever in the form of the new Q1. Now, we have our very first shots of the mini cute ute wearing its production skin. Expected to make its debut in 2016, it would seem that the Q1 will follow the trend set by the Q3 and draw inspiration from the brand's Q5 mid-sizer. Proportionally, it doesn't look dramatically smaller than the Q3. The front overhang is similarly sized, although there's a smaller rear overhang and a more aggressive rake to the rear window. The front windshield looks more aggressive too, and overall, the Q1 looks to sit lower to the ground than its big brother. While it shares a number of parts with the current Audi A1, when the Q1 debuts, it won't be based on the same platform. Audi's smallest car rides on the Volkswagen Polo's platform, while our spies report that the Q1 will instead be based on the Volkswagen Group's MQB platform. Despite the different platforms, though, expect there to be some sharing of powerplants. That means a variety of gas engines, and likely a version of the A1's 1.6-liter, turbodiesel four-cylinder. There should also be an SQ1 coming shortly after the standard model debuts. You know, for all the folks demanding a high-performance, all-wheel-drive, luxury mini crossover.
