Formula 1’s second day of pre-season testing in Bahrain was supposed to be about fine-tuning and confidence building. Instead, for Mercedes and Red Bull, it quickly turned into a bruising reminder that winter optimism can evaporate in a matter of laps.
The desert sun had barely climbed when Mercedes’ garage doors opened with cautious intent – and then almost immediately slammed shut again.
Rookie Andrea Kimi Antonelli, entrusted with gathering crucial mileage, completed just three laps before the W17 ground to a halt with a power unit issue severe enough to force a full engine replacement.
It marked the second consecutive day of disruption for the Silver Arrows. Only 24 hours earlier, Antonelli’s running had already been curtailed by a suspension gremlin, leaving George Russell to shoulder the bulk of the workload.
Now, with yet another mechanical blow, Mercedes’ carefully plotted programme began to unravel before lunchtime.
The timing couldn’t be worse. With engine homologation looming on March 1st, Mercedes is currently the target of a paddock-wide witch hunt.
Rival manufacturers – led by a furious coalition of Ferrari, Honda, and Audi – are trying to torpedo a loophole that allegedly allows the Mercedes engine to spike its compression ratio once it hits operating temperature.
If the FIA bows to the pressure and thwarts the "hot engine" trick, a few missed laps in Bahrain might be the least of team boss Toto Wolff’s problems.
Red Bull and Hadjar Left Stranded
Over at Red Bull, the mood was equally sour on Thursday morning. Despite Max Verstappen’s ominous pace on day one, the team spent the second morning pinned behind garage screens.
The culprit? A "routine issue" during Wednesday night’s car build that reportedly manifested as a stubborn hydraulic leak.
The delay was a gut punch for Isack Hadjar. The Frenchman was scheduled for a full day of data-gathering but spent the first three hours watching mechanics swarm the RB22.
While Red Bull-Ford has been hailed as the new benchmark for energy deployment – by none other than Wolff, the "Ford" era is starting with a reminder that even the best car is useless if it’s stuck on a jack.
By the time Sergio Perez’s Cadillac brought out the morning’s first red flag – coasting to a halt on a disastrous out-lap—the message was clear: in 2026, reliability is the new ultimate luxury.
