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 promises Super Bowl surprise with Dog Show teaser

Last month, Audi announced that it would focus its Super Bowl XLVIII airtime on its new 2015 A3, but a new teaser video promises "something unexpected." Even though there's not so much as a single car in this 20-second teaser, we don't doubt that Audi has created an interesting and creative commercial based on what we've seen in recent Super Bowl ads from the automaker.
While we don't exactly see what could be scary or unexpected about the A3 (or even the S3), there is still the chance that Audi has something up its advertising sleeve for the Big Game. We only have to wait a couple more weeks to find out for sure, but in the meantime, the short video is posted below.

More next-gen Audi TT details revealed

We still only have rumors about the third-generation Audi TT said to be scheduled for launch in late 2014, but based on a report in Car and Driver, we know a tiny bit more about it. The base engine will be the 2.0-liter turbo four-cylinder with direct injection, but horsepower is said to be 220 horsepower - that would make for a nine-hp jump over the current output. The TTS would get an even larger power boost, going from 265 currently to 300 hp. The TT RS would stick with it's 2.5-liter five cylinder, with output increased from 360 to 380 hp. If Audi includes a nice dose of the go-light engineering involved in the TT Ultra Quattro, these horsepower numbers might be even more impressive.
As with the TT concept and first-generation production car, though, it sounds like the brand is concentrating on aesthetics. It's been widely reported that Audi wants to reclaim the juju conjured by the original TT, and while we still don't know what that means outside, CD reports that the interior gets simplified, "futuristic-feeling" styling thanks to instruments served up on a TFT screen. Remember, the first Audi TT had a cockpit that Car magazine dubbed simply, "The Cabin."
About a year after the coupe comes, the Audi TT Roadster will show up and should be joined by the next A5. The news for the next version of the subtly beautiful coupe is the arrival of a plug-in hybrid with torque vectoring via an electric motor for the rear axle. Beyond that is wilder speculation of an A9, which might be called Q9, and which was the four-door-coupe flavor of the month two years ago when it was possibly going to share a platform with the Lamborghini Estoque. According to the CD story, the thinking now is around "a combination of fastback and crossover proportions," a two-fer we've yet to see any carmaker pull off without making us go, "Oh. I see."
