Audi announce their plans to reveal a special g-tron version of the current A3 Sportback.
This specific model uses a standard 1.4-liter TFSI engine offering 110 horses and 200Nm of torque but also two gas tanks able to carry 7 kilograms of CNG.

These thanks are placed under the boot floor and enable a fuel economy of 3,5 kg/100km and a driving range of 400 km. If you combined this with the range provided by the gasoline engine, you will obtain a total of 1,300 kilometers with CO2 emissions of just 30 g/km.

The German model is capable to sprint from 0 to 100 km/h in 11 seconds and hit a top speed of 190 km/h. Depending on driving (at slower of faster speed), the electronic gas pressure regulator decreases or increases the pressure which improves the economy as well.
