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 getting ready for an entire line-up of PHEV models

Despite years of researching any number of standard ICE alternatives, it's becoming clear that different automakers are starting to throw their weight behind their advanced-powertrain technologies of choice. For instance, Toyota is gearing up for its first production hydrogen fuel-cell vehicle next year. Nissan continues to preach the gospel of the battery-electric engine. For Audi, plug-in hybrids appear to be the way to go. The German automaker plans to have a plug-in hybrid version of every one of its models by the end of the decade, UK's Autocar reports, citing comments Audi research and development head Ulrich Hackenberg made at a recent launch event for the A3 Sportback E-Tron. Hackenberg spelled out two variants of the powertrain, including one front-wheel drive version that pairs an electric motor with a 1.4-liter gas engine (this is the version used in the A3), and another to be used for four-wheel-drive vehicles in which an electric motor drives the rear wheels. We couldn't get more information from Audi representatives here on the A3 Sportback E-Tron launch ourselves, and an Audi spokesperson said in an e-mail to AutoblogGreen that the company wasn't commenting further on its plans for plug-in hybrid powertrains in more models. Audi has started pre-sales of the A3 Sportback E-Tron in Germany, pricing the car at about $51,000 with deliveries to start sometime this winter. The vehicle puts out 204 horsepower and can go as far as 31 miles on electric power alone. An exact date has not been set for importing that plug-in to the US, but it will happen some time next year.

Audi A6 gets styling, powertrain tweaks

The Audi A6 is already a fairly handsome, German luxury sedan, but the whole range is receiving some styling updates in Europe this fall. Audi's US arm would not directly confirm which of these updates will be coming to America, instead just telling us that an updated A6 will be coming next year.
On the outside, the tweaks are fairly minor. The company's single-frame grille, which shows up throughout the model lineup, gets some very subtle styling changes, and the lower bumper and its air intakes are also reshaped. More obviously, the headlights have a new form with the LED running lights cutting through them in roughly the shape of a T, as opposed to outlining them, as before. A similar shape is also used for the updated taillights, and there are now rectangular exhaust outlets around back, as well. In profile, the side sills also get a harder crease toward the rear of the sedan.
Inside, things are kept generally the same, as well. There's a new Flint Gray interior color for the A6 and Salsa Red for the S6. But the biggest change is a power-retracting eight-inch infotainment system using the Nvidia Tegra 30 graphics chip. The optional night vision assist system is also improved with new functions, according to Audi.
