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 Nanuk Quattro Concept is a wild surprise ahead of Frankfurt

Volkswagen Group Night ahead of the Frankfurt Motor Show always has some surprises, the first of which this year is the Audi Nanuk Quattro Concept. The all-wheel-drive, turbo-diesel-powered supercar is similar to the Giugiaro Parcour Concept that was unveiled earlier this summer. In fact, the Parcour's creator, Italdesign Giugiaro, penned the Nanuk, and we suspect much of the former found its way into the latter - with some changes, of course.
The diesel engine, a departure from the Parcour, is a twin-turbocharged 5.0-liter V10 TDI unit that develops 544 horsepower and a hole-digging 738 pound-feet of torque, which make the 4,189-pound all-road vehicle able to dispatch 0-62 miles per hour in 3.8 seconds and go on to a 190-mph top speed. Fuel consumption is a relatively low 30 miles per gallon for a car with this much performance.
The Nanuk showcases Audi's Quattro, though it uses a specially designed version of the all-wheel-drive system to get the job done. Audi's next generation of adaptive air suspension is featured as well, which fits the crossover nature of the Nanuk. Drivers are given a range of 2.76 inches of height adjustment, though Audi doesn't mention the car's minimum or maximum ground clearance.

Audi A8 and S8 get another video tease

If there was any doubt before about which car(s) Audi recently teased in a video, now we know for sure. Audi has released another teaser video that confirms we'll at least be seeing the 2015 Audi S8 (and very likely the A8 as well) in the near future, but the big surprise is just how soon we'll see the new flagship sedan. We originally expected to see the sedan receive its official debut at the Frankfurt Motor Show, but now Audi says that the car will be presented about three weeks before the event on August 21.
How do we know this is the S8? Well, aside from it obviously being a large sedan, the true tell that this is its A8/S8 is the front license plate, which clearly shows "S8" on it - we've been doing this long enough to know that Audi's promotional license plates have the model designation in the plate number. As for other details, Audi's trick Matrix headlights shine through the thin veil in what should be the crown jewel of the sedan's new face. There's a little more than a week to go until the car is unveiled, but for now, check out the video below.
