German car maker Porsche looks set to press ahead with its plans to enter Formula 1 motor racing as early as 2026, with the company set to buy a 50% stake in Red Bull Technology. The move will form a partnership according to recently posted legal documents.

The agreement has been on the cards for some time, but has been delayed by uncertainty about new 2026 Formula 1 engine regulations. 

The Volkswagen Group, which owns Porsche, has become increasingly interested in F1 involvement due to the sports growing popularity in the US and China. It is speculated that another VW marque, Audi, will also join the sport, with speculation growing of an agreement with the Sauber Group. 

The disclosure document, which has to be submitted under anti-trust laws, says there will be an initial 10 year agreement with Porsche supplying power units for Red Bull.
