Marko provides update on Red Bull's own engine development ahead of 2026 season

For some time, there has been buzz in the paddock that things with Red Bull Powertrains aren’t progressing as hoped. Whispers suggest that their power units aren’t as powerful as Mercedes’. This all came before the FIA’s decision to reduce the battery’s contribution in the new engine, a move that favors Red Bull, which might face challenges with the electric side of their power unit.

Marko assured Speedweek that there are no concerns about the development trajectory of the engines: "We are on schedule with our engines for 2026, but of course, we don't know exactly what the competition is doing," says the austrian advisor.

Marko must have also heard that Mercedes might have an advantage over the rest of the field. On this, the Austrian said: "There's already talk about who has the lead in terms of engines, but that will only become clear when you hit the track."

This will take place in the first quarter of 2026, when the F1 cars built to the new technical regulations take part in their first test sessions, typically held in Barcelona.
