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.

Despite EV push, Audi will lead hydrogen for VW Group

The cynics among us will assume that Volkswagen Group would rather not affix its flagship brand name to its main hydrogen fuel-cell efforts in the wake of that German automaker's diesel-emissions scandal. Instead, there's less of a taint in having those efforts led by VWs Audi division. And that's exactly what's going to happen, reportedly. Audi will lead Volkswagen's way towards selling hydrogen fuel-cell vehicles to the general public, Automotive News Europe reports, citing comments Audi's new development head Stefan Knirsch recently made at VW headquarters in Germany. That first effort may come in the form of the H-Tron Quattro concept SUV that Audi unveiled at the Detroit Auto Show in January. That model is slated to have a 373-mile range on a full tank of hydrogen (using the optimistic European driving cycle) and includes a rooftop solar panel that can add 621 miles a year via sun rays. And true to Audi's performance-driving bent, the car will offer up to 282 horsepower and 406 pound-feet of torque, for a 0-62 miles per hour time of under seven seconds. Audi will also look to cut production costs by reducing precious metals such as platinum in fuel-cell stacks. As for plug-in vehicles, Audi said at last November's Los Angeles Auto Show that as much as 25 percent of new Audis will be plug-in vehicles by 2025. A month later, Audi said that the A3 E-Tron, which was launched in Europe in late 2014, was already accounting for a quarter of Audi sales in the Netherlands and Norway.

Translogic 164: Driving the fuel cell vehicles of the 2014 LA Auto Show

The LA Auto Show is known for its environmentally friendly vehicle debuts. At last year's show, hydrogen fuel cell concepts from Honda and Toyota joined a lease-ready Hyundai Tucson FCEV to cast a green hue over the convention center. This year, automakers took us a step closer to a fuel cell future by offering drives of their hydrogen-electric hybrids. Translogic host Jonathon Buckley takes a ride in the Toyota Mirai, which is headed for production in 2016. He follows that with a spin in the Volkswagen Passat HyMotion and the Audi A7 Sportback h-tron quattro concept. Which of these fuel cell vehicles holds the most promise? Tune in to find out.
