Sauber
They started off like we all expected them to start this year, with some results around 15th place. But after Charles Leclerc got that 6th place in Baku, it all changed.
The team was motivated, Leclerc showed how quick he can be, and Marcus Ericsson backed it all up with some good results too. The car improved a lot too, and was very quick in a straight line with the Ferrari engine powering it.
The pit stops were pretty quick, especially in Silverstone where they used their place at the end of the pit lane to their advantage.
Next year, with Kimi Raikkonen joining the team, the car has huge chances of being very fast with his feedback, setup and development. Antonio Giovinazzi is quite fast too, so it will be very interesting to see where the team can jump to in the constructors' standings.
Prediction: Raikkonen gets best of the rest in standings.
