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.

Is the Audi R8 E-Tron project back on again?

If you ask Audi about its R8 E-Tron prototype, the all-electric two-seater that was first shown at the 2009 Frankfurt Motor Show, the automaker will tell you that its development program is on hold. Yet, as we reported in January, limited production of the combustion-free coupe may be moving forward... information still officially unconfirmed by the automaker.
New images of the electrified R8 undergoing winter testing in Europe have emerged (above and in our gallery), and the car has been spotted running in Spain as well. Both sightings support reports that the E-Tron, with its 150-mile battery range and 8:09 Nürburgring time, may be back in business. Does the program have a green light, or is Audi merely trying to take some of the thunder from the BMW i8?
Whatever the case, if the R8 E-Tron does eventually make it into showrooms - and we are now led to believe it will - expect production volume to be very low. Assuming it doesn't get shelved again, of course.

Audi introduces leaner, fitter second-generation Q7

After a long run on the market, Audi has finally signaled the end of the first-generation Q7 with the introduction of the long-awaited second-gen version of the brand's first crossover. The 2016 Q7 is a far lighter machine than the vehicle it replaces, thanks to ample use of hot-shaped steel and aluminum. Beyond that, the Volkswagen Group's MLB platform will allow the fullsize Audi to accommodate a range of engines, including more potent versions of the US market's 3.0-liter, supercharged V6 and 3.0-liter TDI. On top of that, the next-gen Q7 will also be available as a diesel plug-in hybrid, complete with a version of the brand's Quattro all-wheel-drive system. The Q7's new design, meanwhile, gives the car an almost wagon-like appearance and profile. The "Singleframe" grille is wrapped in an aluminum-looking surround, not unlike Audi's smaller RS Q3. Audi's cleanly styled headlights flank it, while the large taillights aren't as aggressively angled as Audi's other crossovers. The cabin is lavish, featuring a typically stylish design with plenty of tech. A 12.3-inch TFT display takes the place of a conventional instrument cluster, while the center stack is crowned by its very own display. Even the HVAC display controls are handsome. You can see exactly what we mean in our gallery of live images of the new Q7, straight from the floor of the 2015 Detroit Auto Show.
