Red Bull boss Christian Horner has teased that the “devil is in the detail” with the team’s 2025 Formula 1 car, citing “almost every single component has been changed”.
The Austrian squad became the last team on the grid to reveal its actual 2025 challenger as studio images were released to the world on Tuesday of the new RB21.
Red Bull continued to adopt a secretive approach, though, as the photographs were taken with minimal lighting to obscure the more notable design elements on the car.
However, a surprise soon emerged when shakedown images were posted with the RB21 baring a strong resemblance to its predecessor with minimal visible changes.
Red Bull had been expected to commit to a greater departure from the RB20, the car which began last season as the dominant package but then became difficult to drive.
But while he has acknowledged that the general design is near identical, Horner has indicated that there are greater revisions beneath the surface that cannot be seen.
“Well, the RB21 visually to the RB20 looks very similar, but the devil is in the detail,” Horner said.
“Almost every single surface, every single component on the car, has been changed, upgraded, refined and improved.
“So we’ll get a first indication of what we’ve managed to achieve during these next few days testing.”

Red Bull aiming to eradicate RB20 ‘diva’ traits
Verstappen was victorious seven times in the first 10 races in 2024, but he endured a 10-race winless run as Red Bull’s updates accentuated the RB20’s balance problems.
Horner has addressed that Red Bull’s attention over the winter has been on widening the RB21’s operating window to eradicate the traits that made last year’s car a “diva”.
“RB20, obviously, it won more races than any other car last year in nine Grands Prix and four Sprint races, but it was a little bit of a diva at times – and extracting the most out of the car did become problematic,” he added.
“So what we’re hoping for with RB21 is that we have a much wider operating window, that the car is a little more predictable and slightly easier to work with, so we’ll see.
“We’ll get an indication in these early races, but as always, it’s going to be a season of development from the first race to the last race.”
