Audi is now offering customers climate-friendly Audi e-gas to power the A3 Sportback g-tron – the fuel offer is included as standard and customers will pay only the regular natural gas price. With this deal, Audi is reducing the CO2 emissions of the g-tron fleet when running on gas by 80%, compared to a gasoline car in the same performance class. Early this summer Audi will further expand its product range with two new models – the A4 Avant g-tron and the A5 Sportback g-tron, and the e-gas offer as standard applies to both models.
The e-gas is produced using renewable energy from water and CO2 or from organic residual materials like straw and plant clippings. During its production, it binds exactly the amount of CO2 as is emitted by the car during combustion. Beginning immediately, Audi customers who order the A3 Sportback g-tron by May 31, 2018, will have access to their supply of this fuel for three years as part of the standard package.
“This offer is our next step in climate-neutral, long distance mobility. Our promise to the customers is: no compromises. The g-tron models are sporty, sophisticated and progressive – like every Audi. And with Audi e-gas they are also very climate-friendly on the road,” said Dietmar Voggenreiter, Member of the Board of Management for Sales and Marketing at AUDI AG.
Audi and its partners are producing the Audi e-gas with several processes and facilities in Germany as well as in a number of other European countries. Among other places, the brand obtains e-gas from its own power-to-gas facility in Werlte, a town in the German state of Lower Saxony. The process uses mostly excess green electricity to operate three electrolyzers, which break water down into oxygen and hydrogen. In the methanation process that follows, the hydrogen reacts with CO2. This produces synthetic methane – the Audi e-gas. The fuel is fed into the European natural gas grid and replaces the amount of natural gas that the g-tron model consumes in the New European Driving Cycle (NEDC).
Customers fill up their g-tron models at any CNG fueling station and pay the regular price for the fuel. By feeding the computed volume of e-gas into the natural gas grid, Audi works behind the scenes to ensure the green benefits of the program, including the corresponding reduction in CO2 emissions.
