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 reveals R8 E-Tron Piloted Driving concept at CES Asia

Designed as they are to take the driver out of the equation, you might think that the idea of an autonomous vehicle would seem diametrically opposed to that of a supercar. But Audi disagrees. The German automaker has cooked up a series of "piloted driving" concepts that are increasingly focused on performance, and this could be the ultimate iteration yet. Audi's latest Piloted Driving demonstrator is based on the R8 E-Tron. It's altogether almost identical to the one we saw in Geneva, packing an electric powertrain to deliver 456 horsepower, 679 pound-feet of torque and a 0-62 time of 3.9 seconds. Only in this case, it can do it all on its own, without any driver intervention. To pull that off, Ingolstadt has fitted this show car with an array of sensors, including a new laser scanner, multiple video cameras, ultrasonic sensors and radar transmitters at both ends – all handled by a central "driver assistance control unit." It's the latest in a series of concept cars that has already included a version of the RS7 Sportback designed to lap the racetrack, and the Prologue concept that drove itself to CES. This concept was similarly unveiled at CES Asia, the Eastern counterpart to the tech expo we usually catch in Las Vegas. Just what the point is in engineering (or buying) one of the best-driving cars on the market and then handing over its operation to a computer, we don't quite get. But at least we can rest easy knowing that Audi is not giving up on performance as autonomous tech turns the driver into just another passenger.

The technology study is one of the highlights of CES Asia, and it brings together future technologies – which relate to lightweight design, high-performance drive systems and functions for piloted driving. The Audi R8 e-tron piloted driving concept car is based on the multimaterial Space Frame of the new production R8. A rear car body module made of carbon fiber reinforced polymer (CFRP) integrates the luggage compartment, which extends the frame structure. The walls of the luggage compartment shell are corrugated, so that they can absorb extreme amounts of energy with little material weight in case of a rear-end collision.

Choose your own adventure in Audi's next Super Bowl commercial

Audi has a 60-second spot planned for this year's Super Bowl to promote its S6 sedan, but exactly which spot will air is being put in the hands of Internet users. The ad follows a high schooler as he "embarks on one of the most pivotal moments of his adolescence: prom night." The spot is fixed up to the pivotal moment when he steals a kiss from the prom queen. From that moment, there are three possible endings.
Today, up until 11:59 pm, Audi is running three different versions on its YouTube channel and you can vote on which ending you'd like to see during The Big Game. The winning spot will run on YouTube before the game and then run in the first ad break after kickoff during the Super Bowl. Coca-Cola is running a similar interactive campaign, although its potential endings will involve cowboys, showgirls and a post-Apocalyptic badass, none of which we expect to make it into Audi's prom night spot. Scroll below to view all three alternate ending videos and cast your vote.
