Why was Antonelli penalized after the Barcelona race despite his retirement?

Andrea Kimi Antonelli’s Barcelona‑Catalunya weekend ended in a double setback, as the championship leader retired with a power‑unit failure and then received a post‑race five‑second time penalty for exceeding track limits.

Although the sanction had no effect on the final classification, it added another layer of frustration to a race in which the 19‑year‑old Italian had been fighting hard before his Mercedes came to a halt.

Antonelli spent much of the early phase of the grand prix chasing down team‑mate George Russell, pushing aggressively through the long, sweeping corners of the Circuit de Barcelona‑Catalunya.

In doing so, he triggered repeated warnings from his race engineer, Peter Bonnington, for leaving the track. While race control initially recorded only three infringements, the stewards later discovered an additional violation that had not been detected during the race. As a result, Antonelli received his black‑and‑white warning flag after his fourth breach rather than his third.

In their verdict following the 66-lap Barcelona race, the stewards explained the situation: “The car left the track four times during the race without justifiable reason.

"The Stewards acknowledge that the driver did not receive a black/white flag after his third infringement but rather after his fourth infringement as one earlier infringement was only detected later in the race.”

They added that the decision was based on a full review of the available footage. Despite the procedural irregularity, the stewards emphasised that the regulations still applied.

“However, based on the current regulations and Driving Standards Guidelines, this does not exempt the driver from complying with the regulations.”

The panel also urged the FIA to address the ambiguity exposed by the incident: “As there might be some ambiguity in the relevant guidelines, the Stewards recommend the FIA revisit the current procedures and guidelines as soon as possible.”

It is understood that McLaren had noticed the additional infringement during the race and flagged it, even before race control updated its information. Lando Norris’s race engineer, Will Joseph, informed the reigning world champion mid‑race that Antonelli had already exceeded track limits more than three times and would be penalised.

Antonelli’s retirement, caused by a power‑unit issue shortly after overtaking Russell, meant the penalty had no bearing on the final result. But the Italian admitted the outcome still stung.

“Of course, on my side, it hurts, but it’s not that we were going to win the race today anyway.”

With Lewis Hamilton taking his first victory for Ferrari and Russell finishing second, Antonelli’s championship lead has now been reduced to 41 points.
