Momentum continues to build for Red Bull’s new Formula 1 power unit project, as they announced the signing of five more engine personnel from rivals Mercedes on Thursday… Last month, Red Bull revealed Ben Hodgkinson, who held the role of Head of Mechanical Engineering at Mercedes HPP, would be Red Bull Powertrains’ new Technical Director. Speaking in Portugal last week, Red Bull boss Christian Horner said more signings were on the way, and on the eve of the Spanish Grand Prix, the four-time world champions have announced five new recruits. Steve Blewett, who was Mercedes HPP’s Head of Manufacturing for more than a decade and Production Manager at Williams previously, will become Production Director, while Omid Mostaghimi swaps his role as Mercedes’ F1 electronics team leader to become Head of Powertrains Electronics and ERS.
