By this time next year, the Audi A3 Sportback (http://www.autoblog.com/audi/a3/) will be offered with a variety fuel-efficient powertrains ranging from diesel to the all-electric E-Tron (http://www.autoblog.com/tag/audi%20a3%20e-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 (http://green.autoblog.com/2013/01/31/audi-to-produce-e-gas-synthetic-fuel-wind-solar-co2/). Previously called A3 TCNG (http://www.autoblog.com/2012/09/25/2013-audi-a3-sportback-e-gas-project-shows-off-carbon-neutral-fu/), 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.
It isn't clear how many G-Tron models Audi is planning to build, but the press release posted below (http://www.motorgen.com/2013/02/28/audi-unveils-a3-sportback-g-tron-with-bi-fuel-power-808-mile-ra/#continued) says that its e-gas plant can provide enough fuel for 1,500 cars to travel about 9,300 miles (15,000 kilometers) per year.Continue reading Audi unveils A3 Sportback G-Tron with bi-fuel power, 808-mile range (http://www.autoblog.com/2013/03/01/audi-unveils-a3-sportback-g-tron-with-bi-fuel-power-808-mile-ra/)
