Formula 1's shift to power units with an almost 50% split between electrical deployment and conventional internal combustion power has had far-reaching effects, not just in the engine bay but also throughout the chassis.
Another consequence is a huge increase in driver workload, both before and during races, because maximising the potential of the new power units will require an astute approach to mechanical set-up as well as changes in driving technique from lap to lap. This is one of the key reasons so many drivers have been critical of the new regulations after evaluating early simulator models which suggested the cars would run out of electrical deployment on even moderately long straights.
