Renewable Fuels Ok for Use in Certain Audi & VW Diesel Models

Most legacy OEM carmakers are now focusing massive investments on their efforts to become electric vehicle manufacturers. However, the pursuit of carbon-neutral mobility does encompass other technologies.

Audi in the UK, part of the Volkswagen Group, has, for example, now approved many of its V6 diesel engines for use with the renewable fuel HVO (hydrotreated vegetable oil).

Audi says that HVO is a sustainable paraffinic fuel that enables CO2 reductions of between 70 and 95 percent compared to fossil diesel. It is also more efficient and combusts more cleanly.

Audi models with V6 diesel engines up to and including 210kW that left the company’s factories as of the middle of February can use the HVO fuel in accordance with the European standard EN 15940.

Late last year, Volkswagen announced that all its 4-cylinder diesel engines (TDI) delivered since the end of June 2021 are also approved for operation with paraffinic diesel fuels in accordance with European standard EN 15940.

There is a wide range of different paraffinic fuels, which are produced from biological residual and waste materials such as HVO. These vegetable oils are converted into hydrocarbons by a reaction with hydrogen and can be added to the diesel fuel in any quantities. They can also be used 100 per cent as fuels.
