BBC Sport explains when the Formula 1 cars will be released, and why they will be launched with one-off liveries.

Here is every 2025 F1 car that has been revealed so far plus the dates for the remaining car and livery launches: On February 13, reigning constructors’ champions McLaren unexpectedly became the first team to reveal their 2025 car, the MCL39.

When teams perform a car launch, they claim to be launching their new car in full for the year (though some look to deceive their rivals with what is unveiled), and a livery launch simply pulls the covers off the new colour scheme on the next cars, with the updated paintwork placed on either a show car or previous model from the team.
