For Mercedes AMG High Performance Powertrains, there are also significant changes for this season, with a frozen performance spec for the Power Unit from 2022 to 2026, when the new PU is expected to be introduced. So, HPP have been hard at work, squeezing all the performance they can into the engine before the season begins, because from that point onwards, only reliability upgrades will be allowed.
Another major change for 2022 on the PU side is the new E10 fuel. Hywel Thomas, Managing Director of Mercedes AMG HPP, explains: "There have been bio components in the fuel throughout the hybrid era. What we had was a requirement to have 5.75 percent by volume of bio components. The change this year is that percentage is going up to 10 percent, and also instead of it being open what bio component you use, you have to use ethanol."
But these changes and challenges are what racing is all about, and what HPP work towards and look forward to. Because it brings a fresh opportunity to get a jump on the competition. "With the new fuel, the freeze to performance of the PU over the course of the season and a whole new car, the whole new aerodynamics and fitting the PU within it, there is a huge challenge for everyone involved and especially the team at HPP," Hywel explains. "Of course, that team is super excited to have those challenges and we are really looking forward to the start of the season."
