Audi billboard tracks pedestrians like prison escapees

Audi's adaptive Matrix LED headlights can actively dim and direct light around the road to make driving safer at night. Unfortunately, the tech runs afoul of Department of Transportation rules, so it isn't currently available in the United States. For an idea of what you're missing, a marketing stunt for the new A4 in Belgium is illuminating the night and making pedestrians in the intersection more visible, and safer. The only problem is, it also makes them look like fugitives making an escape. From a giant billboard near the Brussels Central Station, the LEDs from a massive Audi A4 can light up whole intersection. Whenever a pedestrian or cyclist enters the area at night, they are tracked the whole way in a radiant pillar of blue luminescence. Based on this clip, the lights look bright enough to temporarily blind some passersby. Despite the unintended consequences, the stunt is still a very visible demonstration of Audi's headlight technology. Related Video: The video meant to be presented here is no longer available. Sorry for the inconvenience.

Audi A4 TDI plans scrapped for the US

It comes as no great surprise, but Audi of America president Scott Keogh told Automotive News that the automaker has ditched plans to offer the 2.0-liter TDI-powered A4 here in the US. Despite what you may be thinking, Keogh claims the decision isn't based on the ongoing talks between parent company Volkswagen and US regulators regarding the diesel emissions scandal. (Currently, Audi and Volkswagen are awaiting EPA certification for their diesel engines in the US.) The reason, he says, is that the demand for diesel sedans is low here, particularly when compared to the company's lineup of crossovers. "The marketplace speaks, we listen to the marketplace, and the marketplace told us, 'Go with SUVs,'" says Keogh, presumably in his usual straightforward, assuring manner. That's not to say, though, that one doesn't have an effect on the other. We've already seen that the scandal has had an impact on sales. Now, in a country where many were already under the assumption that diesel engines were dirty and noisy, it's no revelation that automakers are less than enthusiastic about expanding their grease-burning offerings. While the news is a bit of a bummer for those of us who have long hoped for more widespread diesel options here in the States (and for whom the whole Dieselgate debacle is downright depressing), there's still plenty to look forward to in terms of greener, cleaner Audis. At the A3 E-Tron event late last year, Keogh was bullish on EVs, promising that it was just the first step in a "substantial commitment." Audi's plan is, in Keogh's words, to "start with the plugs, come in with the full BEVs and then keep rolling from there." He repeated these assurances at the LA Auto show, saying that he expects 20 to 25 percent of Audi's sales to be plug-in vehicles by 2025. Plus, despite the whole diesel thing (which, to be fair, affects far fewer Audi cars than Volkswagens), Audi has been killing it lately. February sales marked a streak of 62 consecutive months of record sales in the US. For an automaker that is repeatedly saying that it believes the future is in electrification, this bodes well for us. Related Video:

Audi unveils A3 Sportback G-Tron with bi-fuel power, 808-mile range

By this time next year, the Audi A3 Sportback will be offered with a variety fuel-efficient powertrains ranging from diesel to the all-electric E-Tron, but perhaps the most interesting is the all-new G-Tron model, which uses Audi's innovative carbon-natural compressed natural gas called e-gas. Previously called A3 TCNG, we first heard about this technology last year, but now Audi has confirmed that this low-emission, sustainable-fuel will debut by the end of this year on the A3 Sportback G-Tron.
To create this e-gas, a plant in Werlte, Germany uses electricity to split water into hydrogen and oxygen. As hydrogen fuel cell vehicles become more popular, Audi says that this process could also be used to produce hydrogen fuel, but to create CNG, it mixes the hydrogen with carbon dioxide to create "synthetic methane." Since it is identical to the CNG available today, Audi's e-gas can be shipped and stored using the existing CNG infrastructure. Making the whole process even greener, Audi obtains the CO2 for this process from a nearby biogas plant, which would otherwise be released into the atmosphere.
Differentiated from the regular versions of the A3, the G-Tron features a pair of tanks under the rear cargo floor holding 15.43 pounds of CNG, which can power the car for almost 250 miles. What's more, the A3's conventional gasoline tank is still in place, giving the car an addition 560 miles of range. In total, that means the A3 G-Tron has a driving range of more than 800 miles. To run on both CNG and gas, Audi made changes to the car's 1.4-liter four-cylinder engine (including the turbo, cylinder head and fuel injection system) and catalytic converter.
