The first days of winter testing for the 2026 season revealed surprises, particularly for Zak Brown, the CEO of McLaren Racing. The impressive power of the Red Bull Ford engine and the reliability of the cars left observers in awe. As Formula 1 prepares for its second testing session in Bahrain, it’s time to take stock of these promising beginnings.
Illuminating Winter Tests
The first collective tests of the 2026 season, held in Barcelona, were marked by an electric atmosphere. Although the teams faced some setbacks, with no less than nine red flags, the overall performances were up to par. The drivers accumulated impressive mileage, a good sign, especially for cars that must deal with an entirely new technical regulation affecting both the chassis and the engine.
A Revolution in Engines Signed by Red Bull
The major novelty of this season lies in the arrival of the V6 turbo hybrid engines developed in-house by Red Bull, in collaboration with Ford. This bold choice has generated a lot of anticipation, and the initial feedback is more than positive. Zak Brown, present during the tests, highlighted the undeniable power of the engine: “I would say the Red Bull engine, the Ford engine, seems very, very powerful. So I tip my hat to them.” This statement reflects a mutual respect between the teams, even within the fierce competition that characterizes F1.
Reliability: A Major Asset
Beyond power, it’s the reliability of the new cars that also impressed Brown. He stated that “the reliability has been very good for such a sophisticated and new regulation.” The stable performances of the cars during testing allowed each team to gather valuable data before the start of the season. In a sport where every detail counts, these first laps reassure about the teams’ ability to quickly adapt to the new technical requirements.

Zak Brown praised the reliability displayed by the 2026 F1 cars in Barcelona.
Upcoming Challenges: Bahrain in Sight
As testing continues in Bahrain, temperatures are expected to be significantly higher than in Barcelona, with peaks around 27°C. These weather conditions will test the endurance of the cars and their engines. The teams will need to adapt their strategies to maximize performance in the heat, a significant challenge for all. This will be an opportunity to see if Red Bull and its rivals can maintain the pace established during the first tests.
A Resurgent Competition
The Red Bull Ford engine is not the only one to have caught attention. Other teams, like Mercedes, have also expressed surprise at the performance of the new cars. George Russell had already praised the Red Bull engine on the first day of testing. In this fierce battle for innovation and excellence, every piece of feedback counts, and the displayed performances could well redefine the hierarchies of the season.
A Promising Future
With six days of testing remaining before the first Grand Prix of the 2026 season in Australia, the pressure is mounting. The teams must confirm their good form in an environment completely different from that of Barcelona. If the Red Bull Ford engine continues its momentum, it could very well become a central element of this season. As the teams compete for supremacy on the track, one thing is certain: the season promises to be as thrilling as it is unpredictable.
