Audi Quattro tech shoots for the moon

Most automakers seem satisfied building vehicles to drive on the Earth's surface. But not Audi. The German automaker is quite literally shooting for the moon with the vehicle you see here. Called the Audi Lunar Quattro, it forms what promises to be an integral part of one team's campaign for the Google Lunar Xprize. That team calls itself Part-Time Scientists, and is the only German contingent of the 25 that originally entered from around the world and the 15 that are still in the race. Sponsored and technically assisted by Audi, the Lunar Quattro is a solar-powered moon rover. It packs an adjustable solar panel and a lithium-ion battery powering four individual hub motors – one in each wheel. It can only travel at a theoretical maximum of 2.2 miles per hour, but outright speed isn't the point here. It's been designed to traverse the difficult terrain of the moon's finely dusted and craggy surface. It'll need to travel at least 500 meters (1,640 feet) and will transmit high-definition video footage from the twin stereoscopic camera on its swiveling head back to Earth. The lunar rover is scheduled to be launched aboard a rocket from Earth to the moon by the end of 2017. The 240,000-mile trip will take five days and is targeted to land north of the moon's equator – close to the place where Apollo 17 (NASA's last manned lunar mission) landed back in 1972. Before that, though, it'll be presented by Audi sales chief Luca de Meo (who's since been named the head of Seat) at the Cannes Innovations Days forum. You can check it out in the gallery and extensive press release below, but first, we suggest you watch the video playlist above while preparing to check out tonight's red moon eclipse.

The group of German engineers are working within the framework of the Google Lunar XPRIZE competition to transport an unmanned rover onto Earth's natural satellite. Audi is supporting the Part-Time Scientists with its know-how in several fields of technology – from quattro drive and lightweight construction to electric mobility and piloted driving. The moon rover will be named the "Audi lunar quattro." "The concept of a privately financed mission to the moon is fascinating," says Luca de Meo, Audi Board Member for Sales and Marketing. "And innovative ideas need supporters that promote them.

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.

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.
