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.

New Audi TT likely headed for Geneva reveal

Between the Consumer Electronics Show and the Detroit Auto Show, Audi is creating plenty of buzz lately for its upcoming third-generation TT. Fortunately, we won't have to wait too much longer to see the next Audi TT, though, as Autocar reports that the coupe will make its big debut at the Geneva Motor Show.
In speaking with Audi's technical chief Ulrich Hackenberg, the article states that the 2015 TT will first be revealed in March before going on sale later in the year. Previewed by the Allroad Shooting Brake Concept (shown above), it isn't that hard envisioning what the new TT could look like: ditch the shooting brake roofline, tall ride height and obvious conceptual design cues. Of course, if this styling is more your thing than the two-seater TT, Hackenberg left open the possibility of a TT Allroad or even a TT-based crossover.

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.
