アウディが再生可能燃料「R33ブルーディーゼル」、「R33ブルーガソリン」を給油して新車販売。化石燃料比でCO₂排出量を20%以上削減 | 3枚目の写真（全4枚）
R33 Blue Gasoline and R33 Blue Diesel consist of one third renewable components, based exclusively on residual and waste materials. These belong to the so-called second-generation biofuels.
From the factory, many new Audi vehicles are delivered with the environmentally friendly fuels R33 Blue Diesel and R33 Blue Gasoline.
The filling stations at the plants have already transitioned to R33 Blue Diesel last year. Now its gasoline-equivalent companion R33 Blue Gasoline is also available. Thus, Audi is contributing to the achievement of climate targets.
