Audi approves hydrogenated vegetable oil for use in V6 diesel engines


Rrenewable HVO fuel reduces CO2 by up to 95% in some Audi models compared to fossil diesel. Audi has announced that some of its V6 diesel engines have been approved for use with renewable fuels as part of a drive to reduce carbon emissions from its internal combustion engine vehicles.

In Europe, renewable fuels such as HVO are more widespread than in Australia. Since June 2021, the 4-cylinder diesel engines in the Audi A3, Q2 and Q3 have been compatible with this fuel. Sweden, Denmark and Italy were the countries with the greatest demand for HVO capable engines.

The renewable fuel approved for use is called Hydrogenated Vegetable Oil (HVO). This is generated by collected used and residual oil that is subjected to hydrogenation to make its properties suitable for use in diesel engines. In addition to being more environmentally friendly, this fuel is said to be a cleaner and more efficient fuel that improves engine performance, especially during cold starts.

HVO can be blended with diesel or used neat. All Audi vehicles eligible to use this fuel will have an XTL sticker in the fuel cap to indicate vehicle compatibility. XTL is used to indicate compatibility with different types of renewable fuels, the acronym encompasses different ways these fuels can be made.

The company has announced that V6 diesel engines rated up to 210 kW in Q7 and Q8 models manufactured from mid-February 2022 will be approved to run on HVO fuel. Audi claims that using HVO reduces CO2 emissions by 70 to 95 percent compared to diesel.

This announcement is part of an ongoing plan to use more synthetic fuels and reduce CO2 emissions. In early March, new Q5 and A6 Allroad will join the HVO program and some Volkswagen Touareg models will also be able to use this fuel.
