Max Verstappen’s chief mechanic Jon Caller is departing Red Bull Racing to join Ford’s endurance racing programme. In his farewell message, he looked back on ten years in the sport, during which he witnessed four drivers’ titles and two constructors’ championships. Above all, he says, he will miss his colleagues.
“The time has truly come to say goodbye to Formula 1. Ten years, four drivers’ championships and two constructors’ titles later… I’ll miss the cars, the destinations and the glamour, but most of all the people who made it so enjoyable,” Caller writes.
The Brit is taking away more from his time in the paddock than just sporting success. “I’ve made friends for life and collected stories I’ll never forget. Now it’s time for a new and exciting chapter, with Ford returning to the highest level of endurance racing. There are great times ahead once again.”
Caller worked on both sides of the Red Bull garage

Caller was already a familiar face at Red Bull before taking over as Verstappen’s chief mechanic. In recent seasons, he worked on the other side of the garage, with the likes of Sergio Perez, Liam Lawson and Yuki Tsunoda. Earlier this year, it became clear that he would replace his twin brother Matt as Verstappen's chief mechanic. Matt left for Audi, where he took up a role as chief mechanic.
Working with Verstappen was not entirely new for Jon: both brothers had previously worked on the Dutchman’s car. This marks the departure of yet another familiar face from the four-time world champion’s immediate working environment. Red Bull won all four drivers’ titles referenced by Caller in his farewell message with Verstappen.
Caller’s possible departure was already discussed in April. At the time, rumours emerged that he had handed in his resignation. With his own farewell message, the mechanic has now made it clear that he is leaving Formula 1 behind. He does not elaborate on the reason for his departure.
A new challenge with Ford in endurance racing
His next employer is preparing to return to the top class of the World Endurance Championship. Ford will enter the Hypercar class with a factory team in 2027 and aims to once again fight for overall victory at the 24 Hours of Le Mans.
