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.

Race Recap: 2013 Griffin King of the Hammers, and notes from a dry lake bed [w/video]

It was a local guy from 90 miles away who beat them all...
The image above shows 129 Ultra4 racing rigs lined up for the start of the 2013 Griffin King of the Hammers. In case you missed Part One that explains why they're there and why they might be doing the most difficult and absurd one-day off-road race in the world, check it out. After a week of races in other events and two days of qualifying for the big show, the men and women who made it in were lined up to do three laps of a course around the 140,000-acre Johnson Valley OHV area in California's San Bernardino County.

Audi releases quartet of A3 commercials, likely headed for Super Bowl

With the announcement from Audi that it's new A3 would be the star of this year's Super Bowl advertising efforts still relatively fresh, it comes as a bit of a shock that what may be game-bound ads for the new small car are already starting to show up.
A3forums found four ads for the new A3, all of which are currently unlisted on YouTube, that play on the idea of young drivers saving themselves for the right luxury car. The spots are amusing, although we'll admit that we've seen better from Audi. Each spot plays like a clip from a documentary, with owners of cars from BMW, Mercedes-Benz and Lexus talking about their regrets when it came to buying a luxury car, rather than waiting for the A3.
We've got all four videos below, so take a look now, as we're betting they'll be pulled before too long.
