Consistent with the strategy of the Volkswagen group, Audi pursues the goal of zero-emission mobility and aims at a carbon neutral balance of all activities by 2050. The horizon is electric, but at the same time the Ingolstadt company is strengthening the sustainability of its own combustion engines. The six-cylinder diesel are now prepared for the use of sustainable fuels such as Hvo (hydrotreated vegetable oil). The Audi V6 Diesel with powers up to 286 vsbslli produced from mid-February can be refueled with Hvo fuel according to the European standard EN 15940. Hydrotreated vegetable oil is a sustainable fuel that allows a reduction of CO2 emissions between 70 and 95% compared to fossil Diesel.
A further plus of the Hvo is the significantly higher cetane number, for the benefit of efficient and clean combustion. «The positive effects are particularly evident in the case of a cold start. Before giving the green light to the new fuel, we tested the effects on multiple components and measured both performance and exhaust emissions, obtaining noteworthy results »says Matthias Schober, head of development of Audi Tfsi, Tdi and Phev engines with V-shaped architecture. Compatibility for the Audi Q5 3.0 Tdi will follow in early March and thereafter will be the turn of the 245 hp step of the A6 allroad quattro. In Europe, the Hvo is also compatible with the four-cylinder diesel engines of A3, Q2 and Q3 produced from June 2021. As for the models based on the Mlb platform, the four-cylinder Tdi of the A4, A5, A6, A7 and Q5 ranges can be supplied with Hvo since the middle of last year in Sweden, Denmark and Italy. Diesel Hvo is already available at over 600 service stations in Europe, most of them in Scandinavia. In the future, Audi and the Volkswagen group will make additional combustion engines compatible with renewable synthetic fuels.
