Red Bull has poached one of Mercedes' senior power unit engineers, Ben Hodgkinson, to head up its new Red Bull Powertrains division.
Red Bull will manufacture its own engines from 2022 onwards following the withdrawal of Honda at the end of this year.
The team will purchase the designs of the existing Honda engine to continue to use it during the upcoming freeze on engine development, while preparing its in-house engine department for new regulations in 2025.
