According to Audi, one of the strategic corporate objectives of the company is to develop technologies that combine driving fun with sustainability.

The German company said it seeks solutions that strike a balance between individual mobility on the one hand and economy, ecology and the requirements of Audi customers on the other.

Audi’s answer comes in the shape of the tron family.

The g-tron stands for drive concepts that run on synthetic Audi e-gas and natural gas and achieve an excellent CO2 footprint.

According to Audi, the first production model to pave the way for CO2-neutral long-distance mobility is the A3 Sportback g-tron.

The term e-tron, on the other hand, stands for the systematic electrification of the driveline.

As one outcome of its research and development projects in this area, Audi is now going into volume production with the A3 Sportback e-tron, a premium compact car with plug-in hybrid drive.

With its plug-in hybrid concept, Audi combines in the A3 Sportback e-tron the advantages of the combustion engine with those of electric drive.

The parallel driveline features a 1.4-liter TFSI engine working in tandem with an electric motor. The power is transmitted to the front wheels via a newly developed e-S tronic system. The liquid-cooled lithium-ion battery is located ahead of the front axle; it stores 8.8 kilowatt-hour of energy, enough to drive 50 kilometers (31.07 miles).

The sporty premium compact vehicle offers 204 hp of total system power and 258.15  pound-feet of total system torque. It accelerates from 0 to 100 km/h (62.14 mph) in 7.6 seconds and reaches a top speed of 222 kph (137.94 mph).

The overall range is 940 kilometers (584.09 miles) and the electric range is 50 kilometers (31.07 miles).

Consumption measured in accordance with the ECE standard averages 1.5 liters of fuel per 100 kilometers (156.81 US mpg).

The A3 Sportback e-tron will go on sale beginning at the end of 2013.

The A3 Sportback g-tron interprets the principle of sustainable mobility in a different way.

Its 1.4-liter TFSI engine runs on Audi e-gas, a synthetic fuel that in chemical terms is almost identical to natural gas and can therefore be distributed as mains natural gas.

This fuel, produced by Audi at its newly completed facility in Werlte, in the Emsland district, is CO2-neutral. Its starting components are water and carbon dioxide, and it is produced using exclusively renewable power.

The A3 Sportback g-tron will be arriving at European dealerships before the end of this year.
