Time for hiding parts is over: Check out all the new 2021 cars here

The 2021 Formula 1 season has started with the first day of the winter test in Bahrain. This is the first time that the cars are on track in full form, which makes for some great pictures.

For the 2021 Formula One season, the plan was to go back to normal, but with a winter test in Bahrain, it's clear that all is not yet normal in the world. The Australian Grand Prix has been postponed due to the ongoing issues surrounding the coronavirus, and so the winter test was moved to Bahrain, which now also hosts the first race of the season.

So the F1 season starts a bit later than expected, and with the necessary changes. Alpine and Aston Martin have been replaced by Renault and Racing Point, but also Williams and Haas have chosen a different livery. The teams have also been able to use two tokens to customise the car.
