Given its partnership with Mercedes, McLaren can call upon the services of its new reserve for this season, former Haas driver Mick Schumacher.
The agreement with Aston Martin means the Woking-based team can also call on reigning F2 champion and Aston Martin Academy driver Felipe Drugovich, as well as one of its former drivers, Stoffel Vandoorne.
The 30-year-old Belgian drove for McLaren for two seasons in Formula 1 in 2017 and 2018 before switching to Formula E and becoming its latest champion.
Vandoorne, who will combine his reserve driver duties this year with his Formula E role with DS Penske, and Drugovich will be available to McLaren for the first 15 grands prix.
We will have access to @AstonMartinF1's reserve drivers, Felipe Drugovich and Stoffel Vandoorne, in the instance that they are required for driving duties for the first 15 races of 2023. 🤝 pic.twitter.com/IRW9SjPy2v
