Kimi Antonelli replaced in Mercedes F1 driver change at Barcelona Grand Prix
Mercedes have confirmed a temporary driver change ahead of the Barcelona Grand Prix, with championship leader Kimi Antonelli set to miss the opening practice session of the weekend. The Italian sensation will hand over his car to reserve driver Frederik Vesti for Free Practice 1 as the team fulfills Formula 1’s mandatory rookie-driver regulations.
The move does not signal any concern over Antonelli’s form or fitness. Instead, it is part of the FIA requirement that every Formula 1 team must provide opportunities for young or inexperienced drivers during selected practice sessions throughout the season. Mercedes have chosen the Circuit de Barcelona-Catalunya as the venue for one of those sessions, a decision many teams often make because of their extensive knowledge of the circuit from years of testing and racing.
As a result, Vesti will take control of the Mercedes W17 during Friday’s opening practice, giving the Danish driver valuable mileage while allowing the team to satisfy one of its rookie-session obligations. Antonelli will return to the cockpit immediately afterward and will participate in the remainder of the race weekend, including FP2, qualifying, and Sunday’s Grand Prix.
The announcement comes at a time when Antonelli is enjoying a remarkable run of form. The 19-year-old arrives in Spain with enormous momentum after securing victory at the Monaco Grand Prix, where he became the youngest driver ever to win the famous race. That triumph marked his fifth consecutive Formula 1 victory and further strengthened his grip on the drivers’ championship.
Antonelli’s rise has been one of the biggest stories of the 2026 season. After replacing Lewis Hamilton in Mercedes’ line-up for 2025, the Italian has rapidly developed into a title contender and now a championship favorite. His performances have consistently impressed both rivals and team officials, with Mercedes team principal Toto Wolff repeatedly praising the youngster’s maturity, speed, and ability to handle pressure at the highest level.
Barcelona presents another important challenge in Antonelli’s title campaign. Unlike Monaco’s narrow street circuit, the Spanish venue is a traditional Formula 1 track featuring a mix of high-speed corners, technical sections, and long straights. Teams often view it as a true test of a car’s overall performance, making it a crucial weekend for assessing competitive order as the season progresses.
For Vesti, meanwhile, the session represents another opportunity to demonstrate his abilities to Mercedes. The reserve driver has previously participated in practice outings and simulator work for the team, earning a reputation as a reliable and technically skilled contributor behind the scenes. Friday’s appearance will allow him to gather valuable data while also showcasing his talents on a Grand Prix weekend.
Despite the headline-grabbing nature of the driver swap, Mercedes fans can remain calm. Antonelli has not been dropped, replaced, or sidelined from the race itself. The change applies only to the first practice session and is part of standard Formula 1 procedures designed to help develop future talent.
With five straight victories already under his belt and a commanding championship lead, Antonelli will be eager to return to the cockpit later on Friday and continue his remarkable season. As Mercedes chase another victory in Barcelona, all eyes will once again be on the young Italian as he looks to extend one of the most impressive winning streaks in recent Formula 1 history.
