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.

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 A3 E-Tron launching at $51,500 in Germany

Audi has put a price tag on the A3 Sportback E-Tron plug-in hybrid, for which presales begin this month in Germany. To get your hands on one of these little guys, Audi is asking for ˆ37,900, or about $51,537 according to current exchange rates. Of course, the base MSRP doesn't include any incentives, but in Germany, those savings would come from certain annual tax exemptions that apply to PHEVs. Buyers in other countries might have more luck in getting into an A3 E-Tron for less. Audi lists its most important markets for the A3 E-Tron as Germany, Sweden, Norway, Holland, the UK and, despite no firm date for the car's arrival here, the United States. These countries, according to Audi, are where buyers are willing to spend their green (or the more colorful banknotes of Europe) on green cars. These places also enjoy nice things, or in Audi's words, "They appreciate the classic strengths of the Audi brand: high-end technology, uncompromising workmanship, sportiness and elegant design." In Germany, Audi will sell the A3 Sportback E-Tron at select dealerships. The service departments of those 100 or so dealers will get special training to work with the high-voltage technology used by the plug-in hybrid. These locations will also feature free-to-use charging stations for customers. The Audi A3 Sportback E-Tron's lithium-ion battery stores 8.8 kWh of juice, and is supplemented by a four-cylinder, 1.4-liter TFSI engine which works parallel to the electric motor. Total output is 204 horsepower and 258 pound-feet of torque, directed to the front wheels via a six-speed S Tronic transmission. The car can reach 60 miles per hour in 7.6 seconds and has a top speed of 138 mph. It can travel of to 31 miles on battery power alone. Deliveries for the 2015 Audi A3 Sportback E-Tron will begin in Germany and Central Europe this winter.
