Audi approves hydrotreated vegetable oil for use in V6 diesels


RHVO energy fuel reduces CO2 emissions in some Audi models by up to 95% compared to fossil diesel fuel. Audi has announced that some of its V6 diesel engines have been approved for use with renewable fuels as part of efforts to reduce the carbon emissions of its cars with internal combustion engines.

In Europe, renewable fuels such as HVO are more common than in Australia. From June 2021, 4-cylinder diesel engines Audi A3, Q2 and Q3 are compatible with this fuel. Sweden, Denmark and Italy were the countries with the greatest demand for engines that could use HVO.

Renewable fuel approved for use is called hydrotreated vegetable oil (HVO). This is created by the collected waste and residues of the oil, which is subjected to hydrogenation to make its properties suitable for use in diesel engines. In addition to being cleaner, this fuel is claimed to be a cleaner and more efficient fuel that improves engine performance, especially during cold starts.

HVO can be added to diesel or used unmixed. All Audi vehicles that are eligible for this fuel will have an XTL sticker in the fuel cap to indicate the compatibility of the vehicle. XTL is used to indicate compatibility with different types of renewable fuels, the abbreviation covers different ways of producing this fuel.

The company said that V6 diesel engines with a capacity of up to 210 kW in the 7th quarter and the Q8 model, manufactured from mid-February 2022, are allowed to run on HVO fuel. Audi claims that the use of HVO reduces CO2 emissions by 70-95 percent compared to diesel.

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