Audi has an eye on the future and is now rolling out cars that are powerful as well as mission-free, a requirement for most brands to survive in future. The most interesting fact about the all-new G-Tron model is that it uses Audi’s innovative carbon-neutral compressed natural gas called e-gas.
Previously called A3 TCNG, we first heard about this technology last year. Audi has confirmed that this low-emission sustainable-fuel will debut by the end of this year on the A3 Sportback G-Tron.
Radically different 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 and catalytic converter. Developing 110 hp and 200 Nm of torque, the Audi A3 Sportback G-Tron has a top speed of 190 km/h, with 0 to 100 km/h taking 11 seconds.
The five-door car consumes on average less than 3.5 kilograms per 100 km of CNG or Audi e-gas which in turn is the fuel that is generated from eco-electricity in the Audi e-gas project. CO2 emissions are less than 95 grams per km in gas mode. So over-all, the mileage looks incredible compared to the power it delivers.
With the sustainable e-gas project, Audi is the first automobile manufacturer to develop an entire chain of sustainable energy carriers. The start of the chain has electricity produced from renewable energy sources; the end-products are hydrogen and the synthetic Audi e-gas.
The construction of the world’s first industrial plant to produce synthetic methane (e-gas) from CO2 and renewable electricity is almost complete in Werlte, Germany.
The CO2 used in Audi’s e-gas plant is a waste product from a nearby biogas plant, operated by power utility EWE. The CO2, which would otherwise pollute the atmosphere, is chemically bonded into the fuel at the Audi e-gas plant.
