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.
