Audi g-tron – part 2 Hello Torben.
– Hi Martina. Welcome. It’s great to have you here.
– Yes, it’s my pleasure. So, we are now in the Audi A4 g-tron and I am driving off now as usual. What is the advantage of the Audi g-tron? It feels good, in any case. Just like any other car. Torben Baier

Social Media Team If you want to protect the environment, with this car you don’t have the issue with alternative drives that you then have to put up with major shortcomings somewhere. We have 170 hp; the car goes over 200 km/h. There are actually no limitations. The one big difference is that you drive much more economically. Why is Audi e-gas special? We are the only manufacturer that also produces its own natural gas. How does that work? As you have just seen for yourself, the wind is blowing. On most days of the year we have more wind than we can even use in the form of wind power.

And we are using that to our benefit: Whenever this happens, Audi powers up its e-gas plant in Werlte and uses the excess wind power to produce its own natural gas – methane, that is. How does that work? We have electricity, we take water – H2O – and make H2 and O2 from it. Then we take H2 and mix it with CO2. In the end, we get methane, which has the chemical formula CH4. The advantage is that we feed it into Germany’s natural gas grid It has a very high storage capacity of four to six months. This means that we can store this wind power for a long time, and even if there is no wind and no sun shines, we can then use this alternative fuel to drive a car. This means a synthetically produced gas that is only available from Audi – is that right? Audi is the only manufacturer to offer something like this. So this is truly Vorsprung durch Technik.
