In collaboration with the U.S. firm Joule, Audi is taking a fundamentally new approach to the diesel fuel of the future. The biotech company, founded in 2007 and based in Bedford, Massachusetts, is working on producing synthetic fuels – Audi e-diesel and Audi e-ethanol – with the help of special microorganisms. They are virtually climate-neutral, as they only release as much CO2 during combustion as was bound during production. According to current projections, a car operated on Audi e-diesel will achieve a good carbon footprint similar to that of a battery-electric car using electricity produced from renewable sources.
