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 Q8 E-Tron could have 370-mile range

Audi technical boss Ulrich Hackenberg has a huge job ahead of him if he's going to add more electrified models his employer's portfolio. Currently, the German company's electrified offerings amount to just the Q5 Hybrid in the US and the A3 E-Tron in Europe, but British auto mag Autocar is claiming that Hackenberg wants to add a Tesla Model X-rivaling electric version of the company's long-rumored Q8 utility vehicle to the plans. That E-Tron model, said to be a high-riding crossover with coupe-like lines, is expected to be Ingolstadt's CUV flagship, positioned just above the Q7 (pictured above).
Autocar further maintains that Q8 E-Tron will borrow its front- and rear-mounted electric motors (good for around 375 horsepower) from the recently revived R8 E-Tron, and the model could be ready as soon as 2017. This sporty CUV is expected to have a much greater range than the two-door electric sports car, however. Figure on about 370 miles thanks to room for extra batteries.
The still-not-confirmed Q8 range is expected to be offered with gasoline, diesel and plug-in hybrid powertrains, and will ride on the same platform as the Q7, albeit fitted with sleeker styling. Like all of Audi's upper-end offerings, it will make extensive use of aluminum for the body and chassis to keep weight down.

Audi TT Sportback Concept rounds out an icon

That German automakers seem singularly fixated on filling any white space between their models isn't new - the last decade-plus has seen their showrooms overflowing with niche models, some of which seemingly occupy sub-genres of sub-genres. To our eyes, there's often diminishing aesthetic and utilitarian returns to go along with the heightened price tags that accompany these models, but we're beginning to think Audi is tackling its personal diversity initiative best. Unlike the often heavy-handed designs from rivals (we're looking at you, BMW), Ingolstadt seems to be doing doing a more graceful job of carving out models between models. The latest proof of this is the TT Sportback Concept, just unveiled here at the Paris Motor Show.
After showing off its Allroad Shooting Brake Concept in Detroit and, more recently, in the Offroad Concept in Beijing amidst rumors of the TT sports car platform expanding into an entire family, we're not surprised to see this more utilitarian five-door hatchback showcar here in France. This, despite the fact that Audi already counts similarly proportioned A5 Sportback and A7 Sportback models in its lineup.
Of the TT line extension concepts, this Sportback certainly looks the most production ready, with a bare minimum of showcar tinsel masking realistic proportions and detailing. We think it's quite handsome from stem to stern, even if it's a bit familiar looking. The design incorporates Audi's trademark big-grille look with the TT's prominent arched roofline and heavily radiused fenders, along with a rear lighting graphic that subtly echoes the A3. Despite its leggy looks, the TT Sportback Concept is surprisingly compact, spanning less than a foot longer overall than the production 2016 TT despite its 4.7-inch longer wheelbase and extra set of doors. Those sleek looks come at least partially as the result of an overall height that sits 1.2 inches lower than the TT coupe.
