The Audi A3 Sportback G-Tron has been on our natural gas-powered radar since it was unveiled at last year's Geneva Motor Show. Just before the big show starts up again this year, Audi put the new G-Tron vehicle on sale in Germany today, starting at 25,900 euros ($35,400 US). Anyone who opts for the Audi e-gas fuel card will be able to cruise the Autobahn knowing that their emissions will be CO2-neutral.
