The radical shift in F1s technical regulations has seen teams forced to adapt to significant change and although the 10 bespoke cars are now over a year in the making, there remain a number of issues.
With a set of restrictive aerodynamic rules, teams are further limited in the design process by the size and shape of their power units, with bodywork often pressed as close as possible to the V6 engines.
"Every year, we take a look at the power unit and the way it sits inside the chassis in order to give us the best lap time," explained Thomas in a Mercedes YouTube video.
"With 2022 being an all-new chassis, what that means is that we have an opportunity to look at everything again.
"There are areas on the car which will be very sensitive to lap time and there will be other areas which are less sensitive.
"What we're trying to do with the PU is we're trying to stay as far away from the sensitive areas to give as much flexibility as possible for the car designers and to package the parts of the PU into areas where there is less sensitivity.
"What that means is working hand in glove with the chassis department and with all those engineers to make sure the PU fits in exactly where it needs to to make sure that we can make the fastest overall package."
