Mercedes has confirmed its 2022 W13 F1 challenger has completed the FIA homologation process ahead of the new season.
F1 will race to an all-new set of aerodynamic regulations this year with teams starting from a largely blank sheet.
Confirming Mercedes had completed the crucial FIA homologation process, a Mercedes spokesperson stated: "[The] W13 completed its FIA homologation process on 13 January 2022.
"The relevant procedures for this [which have changed somewhat for this season, including a reinforced side squeeze test] are captured in Article 13 of the 2022 Technical Regulations."
Mercedes will launch its W13 entry on February 18 ahead of the three-day 'pre-season session' that begins on February 23 in Spain.
The official pre-season test will take place in Bahrain from March 10-12 with the season-opening Bahrain Grand Prix being contested the following weekend.
