A former ally of Lewis Hamilton is plotting his Ferrari failure after being handed a new role at a rival team.
With 2025 having now arrived, Hamilton is officially a Ferrari man, with the seven-time world champion no doubt looking to achieve a record-breaking eighth world title behind the wheel of the iconic red car.
Cowell previously worked as engineering director for the Mercedes-Benz high performance engine division from 2008 to 2013, before then taking up a new role as managing director of the Mercedes AMG high performance powertrains - a role which he held until 2020.
This, of course, coincided with the turbo-hybrid engine era in F1, which Mercedes dominated, winning eight constructors' titles and seven drivers' championships between 2014 and 2021.
"I have spent the last three months understanding and assessing our performance, and I've been incredibly impressed by the dedication, commitment and hard work of this team," Cowell explained in an official statement.
"With the completion of the AMR technology campus and our transition in 2026 to a full works team, alongside our strategic partners Honda and Aramco, we are on a journey to becoming a championship-winning team.
"These organisational changes are a natural evolution of the multi-year plans that we have scheduled to make and I'm incredibly excited about the future."
