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 Prologue concept goes for A9, we give it a ten

If you've been waiting for Audi to roll out a new design language, you need wait no longer as Ingolstadt is displaying just that at the Los Angeles Auto Show this year with the Prologue concept you see here.
Penned by Audi's new design chief Marc Lichte, the Prologue is earmarked to introduce a shift (if not quite a complete change) in design direction for the German automaker. The trapezoidal grille sits wider and lower than on existing models, with the wedge-shaped laser headlights positioned higher above new air intakes with blade elements. The profile rests balanced across its wheelbase to visually emphasize the all-wheel drive that is part of Audi's DNA, with flared arches inspired by the legendary Ur-Quattro. The rear section is inspired by yachts, angled forward to suggest motion, with a narrow strip of LED taillights, full-width diffuser element and twin trapezoidal exhaust tips.
Inside it's all light and surgically clean, with a horizontal dashboard integrating four touchscreen displays running its full width. The system even allows the passenger to select the route for the navigation system and swipe it on over to the driver's display. The headrests on the rear seats and the "sound spoiler" on the rear shelf deploy only when needed, unobstructing the rear view when not.

Audi TT images leak out ahead of Geneva debut

Audi has done an incredibly poor job of keeping the third-generation Audi TT a secret. The first images of the car's rear leaked out late last week, and Audi released its own teaser video for the car last week, too, showing off its aluminum body. Now, the first official photos have surfaced out ahead of the car's debut at the 2014 Geneva Motor Show on March 4. The official photos are practically identical to the renderings from two weeks ago.
However, it appears that Audi has been able to keep one secret up its sleeve. If you look closely at the TT's grille, the badge appears to read TTS. It also has chrome and brushed aluminum trim on the mirror caps, rear diffuser and front air dam. The interior is also quite similar to the concept interior of the new TT was first shown in January at CES. So, images of the actual TT are likely to still be fresh when the car rolls across the stage at Geneva.
Check out all of the leaked photos in the gallery, and official details about the 2015 TT are expected in the next 24 hours.
