Evolving the tron naming seen with the a3 e-tron Audi has gone a step further with the A3 g-tron. Thats G as in Gas, Compressed Natural Gas. The G-Tron offers a factory installed CNG kit for efficient operation.

The two largest benefits to CNG sourced propulsion are that it cuts c02 emissions and that CNG is cost efficicent to produce and use. Audi claims 100 km of driving will use 3.5kgs of CNG. One kg of CNG costs between 75 cents to a $1.50 depending on location.

Audi also cites 400 km on CNG power alone, while making a combined 1300km between petrol and CNG. It will swap to petrol when CNG levels run low. Enough to satisfy a single fill up per month I'd say...



So the question is do you think Q3 could benefit from this technology? To take it one further will the Q3 see this type of technology?

Where would you refill a natural gas powered car? I haven't seen a pump anywhere that you could use, and its not like electric cars where every house on the grid can participate.

Its worth the research but I don't see this technology becoming mainstream any time soon.

you can use CNGprices.com to locate facilities near you. There are 15 locations with available CNG all clustered within 30 minutes of my house.... Perhaps if you live in the sticks this is not a viable option, but for those in major urban centers it certainly is. Besides rural folks don't particularly have the appetite for electric vehicles (and CNG) as the "progressive" city dwellers. I use progressive loosely, if not sarcastically ;)

and natural gas prices will just go up too eventually

there will always be a market for petro in my opinion

it will dwindle over the decades when more alternatives are offered.

unless someone offers a synthetic alternative that is cheaper that can also work in petro engines.

I don't really think that a diesel hybrid is going to happen anytime soon. Diesels are usually more expensive, so a hybrid would be pretty pricey. Any fuel savings I think would be dashed by the extra cost.
