Back in September, we reported that Audi are to produce their own fuel for cars, so it makes perfect sense for them to reveal a model that runs on Compressed Natural Gas (CNG) – the Audi A3 g-tron.

The A3 g-tron is powered by a tweaked version of Audi’s 1.4 litre TSI petrol engine which can run on both -gas and petrol, with the A3 g-tron normally using the petrol just for start-up and switching over to e-gas as soon as it’s running.

Audi has provided two fillers under a common fuel flap – one for e-gas and one for petrol – with the A3 g-tron producing a total of 108bhp with the dual-fuel setup, enough to power the A3 g-tron to 62mph in 11 seconds.

The A3 g-tron has storage for 14kg of e-gas in twin tanks under the luggage compartment – stored at 200 bar – which is enough for an e-gas range of around 250 miles. Add in the petrol range and the A3 g-tron can manage around 300 miles more.

No mention of when the A3 g-tron will go in to production, but Audi are to run 1500 A3 g-trons for 15000 kilometres a year in trials which, using fuel from Audi’s e-gas facility in Werlte, with emissions of just 30g/km in total.
