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.

2015 Audi S8

You've gotta hand it to the Audi A8. Last year, Mercedes-Benz launched the truly stunning S-Class, putting the rest of the high-dollar luxury flagship class on notice. With the brand-new S-Class turning heads and garnering all sorts of praise from the automotive press, classmates like the BMW 7 Series, Jaguar XJ and Audi A8 started to look, well, old. But Audi didn't see fit to just let its big sedan carry on and let the Mercedes take the cake.
So when Audi refreshed its A8 line for the 2015 model year with only minor updates, I kind of shrugged it off as just a quick way to keep the big sedan fresh until an all-new, hopefully S-Class-trumping version arrives. But then I drove the S8 pictured above, and I'm no longer so sure the Merc's shadow is as big and imposing as it once was.
Spoiler alert: the Audi S8 is simply fantastic.

Audi A3 E-Tron starts at $38,825

Audi has announced the pricing for the new A3 E-Tron plug-in hybrid, listing the five-door's base price at $38,825. Adding the mid-range Premium Plus elevates the price to $42,925, while the top-of-the-line Prestige will demand $47,725. Of course, like so many hybrids the A3 e-tron's price is not so simply explained. The PHEV will likely be eligible for a $4,168 federal tax credit, while additional state tax credits are also available depending on where you live. And, if Audi's announcement isn't exciting enough for fuel-sippers across the country, we have another piece of good news – the A3 e-tron's configurator is live. While it's no different than any of Audi's other online configurators, potential owners can get a great rundown of the A3 E-Tron's entire options sheet. There's the usual array of options ranging from an MMI package on the base model, to a Technology Package on the mid-grade model, and a Sport Pack on the Prestige trim. With just a bit of fiddling – and while staying out of the accessories catalog – we were able to run the A3 E-Tron's price up to $49,025. That's just shy of what the car starts at in Germany. You can check out the official press release on the E-tron MSRP announcement below, or just head over to Audi's US consumer website and have a go with the configurator.
