Hamilton says a computer glitch ruined his qualifying lap at Suzuka

Hamilton left guessing after Suzuka setback

Lewis Hamilton admits he has "no clue" how the Japanese Grand Prix will unfold after a computer algorithm glitch compromised his qualifying performance at Suzuka.

Despite incremental improvements through the early phases, Hamilton conceded the underlying pace deficit was clear.

Algorithm glitch costs crucial time

The defining moment of Hamilton’s session came in Q3. After a snap of oversteer, a computer algorithm controlling battery energy deployment was thrown off balance — a critical issue given how heavily deployment is managed electronically.

Drivers are required to avoid such snaps, as they can confuse the system and disrupt energy delivery. In Hamilton’s case, the consequences were immediate and costly.

"The deployment is definitely a big part of it. My first lap [in Q3], I was up, but I lost two-and-a-half tenths on the back-straight through deployment after a snap of oversteer, and it changed the whole algorithm."

He added: "It should be that you catch it and keep going."

The time loss ultimately shaped his final grid position, marking his weakest qualifying result of the season so far.

Race outlook: more questions than answers

Looking ahead to Sunday, Hamilton was candid about the uncertainty surrounding race conditions. Limited exposure to competitive traffic during race simulations has left him without clear reference points.

"I really have no clue what the race will be like, I wasn't around anybody in race simulations, but it is not normally a track where there is a lot of overtaking, so I expect it to be less than in China."

Beyond race craft, Hamilton also pointed to broader performance concerns. As McLaren continues to extract more from its Mercedes engine package, he believes the challenge facing his team is significant — though not solely power-related.

"As [McLaren] start extracting more of the power of that Mercedes engine, we have a real job on our hands, but I think the engine is only a part of it, and this weekend at least, the chassis has not been on par with the Mercedes."

With both power unit optimisation and chassis performance under scrutiny, Hamilton heads into the Japanese Grand Prix facing a race defined as much by uncertainty as by opportunity.
