Should policymakers support renewable-fuel combustion vehicles alongside electric vehicle mandates?
BMW is testing a large fleet of diesel vehicles using unblended hydrotreated vegetable oil (HVO) to advocate for new regulatory standards for renewable fuels. Since January 2025, the manufacturer has filled all German-built diesel cars with HVO before they leave the factory.
Why it matters
The automaker is building a technical evidence base to convince regulators to classify vehicles running on renewable fuels as a distinct category. This initiative could influence future climate-related standards for internal combustion engines and household vehicle ownership.
The 12-month trial involved over 600 diesel cars that utilized HVO for 80% of refueling events. HVO is now available at 6,130 European stations, and the fuel can reduce CO2-equivalent emissions by up to 90% according to manufacturer reports.
The players
BMW Group
A German luxury vehicle manufacturer that is currently evaluating the use of renewable fuels in its existing diesel and gasoline lineups.
Neste
A refined fuel producer that reports significant CO2-equivalent emission reductions from the use of hydrotreated vegetable oil.
Bosch
An international engineering and technology company that provides the digital twin platform used to monitor refueling in the BMW test fleet.
The details
BMW conducted the trial without modifying the hardware of any test vehicles, relying on Bosch technology to track refueling data via a digital twin. By matching payment records with forecourt data, the company verified the compatibility of HVO with existing diesel engines. Additionally, a separate pilot in Madrid is currently testing 20 gasoline vehicles using Nexa 95 fuel to explore further renewable options.
Timeline
January 2025: BMW began factory-filling all German-built diesel models with unblended HVO.
July 2026: The Nexa 95 pilot program commenced in the Madrid area.
The Home Front
This effort represents a potential shift in how international emissions regulations treat the lifespan of existing combustion vehicles. It moves the focus away from total vehicle replacement toward utilizing renewable fuel infrastructure to reduce household carbon footprints.
Owners of newer diesel models should verify their owner's manual or local BMW dealer for specific fuel compatibility before using alternative fuels. While this test shows promise for renewable fuel, confirm availability in your region before relying on HVO for daily logistics.
The takeaway
Renewable fuels like HVO are being tested as a way to lower emissions without changing your car's hardware. Keep an eye on regional fuel standards to see if renewable alternatives become more widely available at your local pump.
