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.

2017 Audi A4 evolves into a larger, lighter luxury sedan [w/video]

Audi took the evolutionary, rather than revolutionary, approach when it came time to redesign the brand's A4. While the latest generation's look might not set hearts racing, a plethora of tiny tweaks by the engineers manage to make the the four-door larger, up to 264 pounds lighter, and slice the drag coefficient down to 0.23. Audi has made its modern reputation on the style and quality of its interiors, and the new A4 seems to make good on that tradition. In-cabin appointments and tech see a serious upgrade, including offering Audi's fully digital, Virtual Cockpit, instrument panel. In the US, the new A4 arrives for the 2017 model year offering power from either diesel or gasoline. The 2.0-liter TDI is essentially a carryover from the Audi lineup, but the 2.0-liter TFSI sees some big upgrades, including a new cylinder head. It's now rated at 252 horsepower and 273 pound-feet of torque. At launch here, all A4s get a seven-speed S-tronic dual-clutch gearbox. Front-wheel drive and Quattro all-wheel drive are available. For an added dose of forbidden fruit, you can check out the crimson A4 Avant in the gallery above the from Frankfurt Motor Show. Take a good look because this long-roof variant isn't coming to the US. Yes, we're listening to sad violin music, too. Although, the next Allroad is coming here eventually after that higher-riding wagon debuts.
