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.

2016 Audi R8 E-Tron packs 456 hp and goes on sale this year

For the longest time, the Audi R8 E-Tron seemed like such a fantasy, we never really though it'd come to fruition. But it's here, in second-generation R8 form. It's really, actually, finally here. It looks like a electrified R8, too, with oversized, EV-spec wheels, and a revised front fascia that lends itself well to the more chiseled design of Audi's mid-engine coupe. Thanks to that nice shape and those air-slicing wheels, Audi has achieved a drag coefficient of 0.28 for the R8 E-Tron. The 92-kWh, T-shaped battery is actually integrated into the center tunnel behind the passenger compartment, so it helps with the car's weight distribution and center of gravity. The two electric motors are mounted at the rear. As for the specs, things look awesome: 456 horsepower, 679 pound-feet of torque, 0-62 in 3.9 seconds, top speed of either 130 or 155 miles per hour, a range of 280 miles and a charging time of less than two hours. And it's going on sale. Like, for real. Audi's press blast clearly states, "Upon customer request, the R8 E-Tron will be available for order in 2015 as an electrically powered sports car in supreme hand-built quality." Consider us stoked. Electrified: Audi R8 e-tron The second generation of the Audi R8 forms the basis for two more models. Audi has made major engineering developments in its high-performance electric sports car, the R8 e-tron. The latest evolution of the vehicle takes up the multimaterial Audi Space Frame from the new series-production model. The supporting structure was enhanced by a CFRP rear-section module comprising the luggage compartment. The walls of the CFRP luggage compartment well are corrugated. This way, in the event of a rear-end collision, more energy can be absorbed despite the reduced material weight. Thanks to targeted modifications to the outer shell and on the wheels, the Audi R8 e-tron achieves an aerodynamic drag coefficient (cd) value of 0.28. In terms of performance and range, the car enters entirely new dimensions. The large T-shaped battery is structurally integrated into the center tunnel and behind the occupant cell – optimally positioned in the car. It supports the dynamics of the R8 e-tron with its low center of gravity. Audi produces the high-voltage battery itself, for the first time based on a newly developed lithium-ion technology which was specially conceived for a purely electric vehicle drive.

Audi boss: no to minivan

Well done to you, Rupert Stadler. We salute you. The Audi exec went on record during an interview with Automotive News and basically shut the door on the idea of a Audi-badged minivan. When asked by AN, Stadler pointed to the high conquest rate enjoyed by crossovers and SUVs compared to minivans. On top of that, Stadler argued against vehicles like the BMW 2 Series Active Tourer by pointing out that customers tend to shy away from minivans because of the image they put forth. "Consumers are more likely to switch to an SUV and are more likely to pay a premium price because SUVs are considered more emotional," Stadler told AN. "We would rather be the emotional choice than the rational choice." It's not all good news, though. Stadler gave a resounding "no" to an A8 wagon, based on the Prologue Avant Concept, as well as a BMW 6 Series rival. Instead, Audi will focus on the upcoming Q8 SUV, which the exec said was "more likely to be a winner than a large coupe." The company is also hard at work on additional Sportback models, although Stadler didn't elaborate on which models could get the five-door treatment. Related Video:
