Audi and BP have announced that they will be entering a new strategic partnership as the former firm prepares to make its foray into the world of Formula One.

Under the new partnership, BP and its specialist lubricants business Castrol will work with Audi to co-engineer fuels and Castrol lubricants to extract maximum performance from Audi's engines utilised in the sport.

Both firms will also be developing sustainable fuels, as required by the FIA technical regulations for 2026. This fuel must achieve greenhouse gas emissions savings relative to fossil-derived petrol of at least 65%. BP will also develop and supply Audi with a range of bespoke Castrol lubricants and greases including Castrol EDGE, Castrol's most advanced engine oil, for the V6 engine. Electrical components of the Audi Formula One power unit will benefit from the Castrol ON range of electric vehicle fluids.

BP will additionally become the first official partner of the future Audi factory team in Formula One. This will include marketing and branding rights for BP, Castrol and Aral brands (Aral is BP's leading fuel and retail brand in Germany).
