All 10 teams contesting this year's championship have launched their new cars, most of them with online presentations, followed by pre-season publicity shakedowns on the track. The new cars are reminiscent of last year's cars, given the major regulation changes that were meant to have been brought in this year were deferred until 2022 due to the ongoing Covid-19 pandemic.
