With Red Bull winning the WCC and WDC this year, as well as the WDC last year, I realised that either Mercedes or Red Bull have won these titles for the last 13 seasons (14 if you class Brawn/Mercedes as essentially the same team). I believe this is the longest run that we've had in the history of the sport, and based on what we saw this year, it doesn't look likely to end soon.
Which team are most likely to end this run?
The hybrid era has largely been dominated by the works teams and most well resourced teams, which would point to Ferrari being the most likely. However, given the cost cap and the engine freeze as well as Ferrari's whimper of a season and internal turmoil, there is a lot of doubt as to whether they can mount a serious challenge in the next couple of years.
The engine freeze may allow customer teams to be more competitive (as we saw in the last engine freeze), which would put Aston Martin and Mclaren as most likely contenders. Those teams have managed only a handful of wins/podiums between them during the hybrid era. It's hard to see how they could transform into championship winners quickly.
Is Red Bull/Mercedes' winning run problematic for the sport?
In my opinion, it's not as long as the seasons are competitive and the races are interesting. Outright domination by one team is what will turn viewers away.
Interested to hear everyone's thoughts.
