Set to up the eco-ante later this year is Audi’s new e-fueled g-tron 5-door hatchback.

Carrying design elements and other familiar amenities from previous A3 outings, the new g-tron is similar in every way except the fuel option. But in this story, the car is only part of the eco-tale.

Powered by Audi’s CO2-neutral “e-gas,” the g-tron sportback will incorporate CNG (compressed natural gas) as its primary motivational option. Produced in Werlte, Germany, the new fuel will be developed in the world’s first power-to-gas plant built specifically for CNG production.

Cheaper than gasoline and easier on engine lubricants than gas engines, CNG has been shown to offer an eco-friendly tailpipe option relative to the dead dinosaur variants. Not without its detractors and problems, CNG has been gaining acceptance amongst select manufacturers for years. Consumer pickup, on the other hand, has been less than spectacular. The tron-of-g hopes to change the perception.

Audi’s engine of choice is the new 1.4 TFSI. With modifications to the upper head area, turbo-charging units, injection system and catalytic converter, the powerplant delivers a whopping 110 hp (81 kW) and 148 ft.lb (200 Nm) of torque. These numbers bring about a top speed of 118 mph (190 km/h), with 0 – 60 mph (0 – 100 km/h) times plodding in around the 11.0 second mark.

But performance isn’t what the dance is all about. Consuming a meager 3.5 kilograms per 100 km (7.7 lbs per 62 miles) of CNG, the g-tron provides an impressive range of 1,300 km (807 miles), emitting only 30 grams of CO2 per kilometer (48.28 g/mile) in the process. In gas mode, tailpipe stuff is only 95 grams per kilometer (152.89 g/mile).
