Technical analyst Paolo Fillisetti examines just what is going on with Mercedes’ worrying trend of F1 engine failures, and why McLaren could be protected.
The Canadian Grand Prix is known for being demanding on power units, with high throttle usage and a crucial need to recharge batteries, especially compared to previous races in Imola, Monaco, and Spain. Despite improvements in engine reliability during the hybrid era, Mercedes HPP units experienced multiple failures across the Imola-Monaco-Spain races. Issues included throttle problems for Kimi Antonelli at Imola, a breakdown for Russell in Monaco, and engine failures for Alonso and Antonelli in Spain. Mercedes took proactive measures to prevent further failures after identifying electrical and short circuit problems in these incidents. Antonelli’s engine was sent for investigation, highlighting concerns for Mercedes and its customer teams like McLaren, Williams, and Aston Martin. Questions arose about potential factors like power unit installation and cooling systems influencing the failures, sparking speculations in the Barcelona paddock.
