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 Allroad Shooting Brake showcar is a 124-MPGe hybrid E-Tron

The leaked images of the new Audi Allroad Shooting Brake that came out Friday showed us what the show car will look like, but it wasn't until the official press release came out today that we learned just how much E-Tron is hiding in its powertrain. Turns out, it's a lot. An 8.8-kWh lithium-ion battery can power the car for over 31 miles. The Allroad Shooting Brake is powered by a hybrid (gas-electric) powertrain that can put out a total of 300 kW of power (479.42 pound feet of torque) and, under the right circumstances, get the fuel efficiency equivalent of 123.8 mpg US, Audi claims. The gas side is made up of a 2.0-liter four-cylinder turbocharged engine, and then there's an electric motor on each axle. An 8.8-kWh lithium-ion battery can power the car for over 31 miles on battery power alone. There are three drive modes (EV, Hybrid and Sport). This is also the first time Audi has put its Allroad and E-Tron "form languages" together, which means this E-Tron Quattro "is not limited to paved roads" and can handle "light off-road conditions." The two electric motors help bring the car from 0-62 miles per hour in 4.6 seconds on up to a top speed of 155 mph. Audi has paid attention to shaving weight from the 3527-pound, four-seater, including making the wheels out of carbon-fiber reinforced polymer (CFRP) and using an aluminum underbody panel. We described some of the concept's visual hints in the original post (Q1?), and now Audi says that the car contains "a host of visual elements of future sports car models" (TT?). We will get our first real glimpse of the Allroad Shooting Brake show car at the Detroit Auto Show early this week, so look for live pics then, especially of the interior that is supposed to be reminiscent of an airplane and a user interface panel that is said to work like a smart phone. In the new press release, Audi's Ulrich Hackenberg said the Allroad Shooting Brake represents, "a concrete look into the near future," and we're totally fine with that. Crossover in a compact package: The Audi allroad shooting brake show car Crossover concept car is highly functional for recreational sports Powerful and efficient hybrid drive features two electric motors Prof. Dr. Ulrich Hackenberg: "A concrete look into the near future." Sporty, compact and versatile: It is with these attributes that the Audi allroad shooting brake makes its debut at the North American International Auto Show (NAIAS) in Detroit.

Audi A3 G-Tron offers big range, few emissions

Audi is exploring a variety of sustainable transportation technologies beyond the traditional diesel, hybrid, plug-in and electric options, including the compressed natural gas A3 Sportback G-Tron that debuted today at the Geneva Motor Show.
The most interesting thing about this rather innocuous-looking A3 Sportback is that when run on Audi e-gas, the car becomes completely carbon neutral, emitting no more CO2 than was chemically input in this special fuel's production. Audi has already broken ground on a new plant - powered by renewable energy, of course - that uses electrolysis to produce e-gas, which could then be made available through any natural gas distribution network.
