Overview
- The trial, which began in early July, runs about 20 unmodified BMW and Toyota vehicles exclusively on Repsol’s Nexa 95 renewable gasoline for six months.
- Bosch supplies its Digital Fuel Twin system to link vehicle telemetry, station records and fuel‑card transactions and to certify that the fuel used is the tracked renewable product.
- Partners say the project will produce real‑world, validated evidence to support the Vehicles running Exclusively on Eligible Fuels (VEEF) framework in upcoming EU Renewable Energy Directive discussions.
- Repsol markets Nexa 95 as a drop‑in fuel made from organic waste such as used cooking oil and biomass and claims roughly a 70% lifecycle CO2 cut versus conventional petrol, but availability is currently limited to Repsol stations in Spain.
- If regulators accept VEEF pathways, manufacturers could use verified renewable fuel use to meet emissions rules and extend the viable life of combustion models, but feedstock limits, lifecycle accounting and wider scaling remain the main obstacles to that outcome.
