GALLERY: The 2022-spec Formula 1 cars hit the track as Barcelona pre-season running begins

The silence has been broken at Barcelona as the glorious roar of all 10 teams' Formula 1 cars filled the air at Circuit de Barcelona-Catalunya on Tuesday.

The day began with Haas unveiling their 2022 challenger, the VF-22, and Alfa Romeo brought out their C42 bedecked in a special testing livery for the three days. That camouflaged look will be replaced by Alfa's permanent livery when they reveal it on February 27.
