Kimi Antonelli has detailed what caused his Barcelona Grand Prix retirement and that Mercedes is set to introduce measures to solve its Formula 1 power unit unreliability from the Austrian GP.
During an Italian media interview at the Red Bull Ring, Antonelli confirmed that he will run a new power unit paired with an updated battery pack featuring several corrective measures made by Mercedes following its recent breakdowns – something team boss Toto Wolff said the team must fix if it wants to fight for the world titles.
