Sounds like the new rules want to favor a single team (guess who , RB without a doubt) . They had great aerodynamics in the year 2016 and it was only because Mercedes had a higher power engine it was able to beat them through almost all season. Now with the wider bodies and tires if we add them to a team with great aerodynamics this translates into even better aerodynamics so I think RB is the team to watch out this season with these new rules.
