For the qualifying, Mercedes renewed the power unit of Valtteri Bottas. The fourth ICE (internal combustion engine), turbocharger, MGU-K, MGU-H, and exhaust were introduced this season.
Regarding the reason for the replacement, a Mercedes spokesman said that it was not a problem, and it was considered to be a replacement for strategic reasons due to concerns about the power down and reliability of the stocked PU by operating in the high output mode. Be done.
Bottas was the fastest in the qualifying on the first day and started the sprint qualifying on the second day from 1st place. Since the grid demotion penalty for the introduction of the fourth car will be applied to the grid of the final race, Bottas will start the race on Sunday from the end regardless of the result of the sprint qualifying.
This year, the 8th year since the introduction of the V6 hybrid, ICE, TC (turbo), MGU-H, and MGU-K will each have up to 3 units per year, CE and ES will have up to 2 units each, and the maximum number of uses will be newly set from this season. The exhaust system can be used up to 8 sets a year without demotion penalty. However, if the calendar is 19 races or less, the annual allowable number of MGU-K will be limited to 2.
