Red Bull Racing team principal Laurent Mekies warned that despite the promising debut of the new in-house engine during the Bahrain tests, the struggle could prove laborious in 2026.

While rookie Isack Hadjar experienced some reliability issues, Max Verstappen quickly proved competitive against Mercedes, Ferrari and McLaren during the winter tests in Bahrain.
The Dutchman even demonstrated different battery charging techniques during the tests, a key element with the new 2026 power units, heavily dependent on energy management.
Promising debut, but caution is required
This performance, however, relies on the robustness of the first engine designed by Red Bull Powertrains — named DM01 in tribute to Red Bull founder Dietrich Mateschitz — and on the integration with the gearbox, subjected to high revs particularly during downshifts into first gear in corners previously taken in third.
Interviewed by TSN before the Australian Grand Prix, Mekies praised the technical feat: « What the team has achieved, what the engine department has accomplished, is historic. Starting from scratch three years ago, reaching this stage, seeing the chassis and engine teams working together around the car and seeing it take to the track, is a huge achievement. It’s the kind of thing only Red Bull can do. »
But enthusiasm quickly gives way to realism: « The next second, you forget that and you look at all the steps that remain to be taken to be at the right level. We know the road is long. We know that it will be painful, but it is fair to say that the starting point is exceptional. »

A potentially brutal development cycle
Mekies detailed what he means by painful: « We are extremely aware of the amount of work that remains to make the power unit work as we need it to, to make the car work with the engine as it should, and then bring this package to the level of our competitors who are performing at an incredible level. »
« There will be moments when we look at the standings and where the gap to P1 will seem huge, estimates the French engineer. There will be moments when the car stops on track. But we know the scale of the challenge. We know how bold a decision it is to go with our own engine. It’s the kind of challenge we love at Red Bull. »
Engine hierarchy: first clues
The tests hint at a hierarchy among the five engine manufacturers: Ferrari and Mercedes currently seem to be competing for the benchmark status; Red Bull is said to be slightly behind, but competitive; Audi F1 Team shows measured optimism, with solid stints; Aston Martin, powered by Honda, has accumulated reliability difficulties in Bahrain, with very short and unconvincing stints.
In summary, while the launch of the Red Bull Powertrains project constitutes a remarkable industrial success, the battle against established engine manufacturers promises to be demanding. The real test will not be the initial enthusiasm, but the ability to endure a long, complex development potentially fraught with pitfalls.
