    Audi e-diesel and e-ethanol

    Audi e-diesel and
    e-ethanol

    Audi is promoting the development of new CO₂-neutral fuels.** The underlying technology is completely new: Microorganisms utilize solar energy to produce synthetic ethanol and synthetic diesel from carbon dioxide and water.
    The problem has been familiar for a long time, but it has yet to be solved: The combustion of conventional petroleum fuels pollutes the atmosphere by releasing carbon dioxide into it. Ethanol and diesel made from renewable raw materials such as maize and rapeseed generally achieve a better environmental balance, because the plants have already previously absorbed the CO₂ that is released when they are combusted.** But such fuels are costly and compete with food agriculture – so they do not represent a long-term solution in a world whose population continues to grow increasingly rapidly.

    Ecobalance

    Ecobalance

    Audi creates an ecobalance for each new model that evaluates all phases of its lifecycle. The brand’s lightweight and efficient models are particularly effective during the operating phase – thanks to know-how in ultra-lightweight design and drive technology.
    Ecobalance, also known as life cycle analysis or life cycle assessment (LCA), analyzes the environmental impact of a product throughout its entire lifecycle. It serves as a quantitative evaluation of ecological aspects such as the emission of greenhouse gases (including CO₂)**, energy consumption, acidification or summer smog. In compiling ecobalances, Audi uses a standardized procedure in accordance with ISO 14040.
