Red Bull Motorsport Advisor Helmut Marko has confirmed Sergio Perez has no more spare parts after crashing out of FP1 at the Hungarian Grand Prix.
The Mexican's miserable run of form continued just four minutes into the opening session of the weekend when dipping a wheel onto the grass at Turn 5, spinning into the barriers.
Red Bull had introduced a new upgrade package for both Perez and championship leader Max Verstappen at the Hungaroring, with the sidepods boasting the biggest change.
But the left-hand side sidepod, as well as the front wing, suspension and floor were all damaged in Perez's crash.
Viewed by others:
Red Bull's mechanics were able to repair Perez's RB19 before FP2, though a lock-up on his only Soft tyre run left him straggling on the leaderboard.
But a bigger concern would be the fact that he has used his allocation of spare upgrade parts for the weekend, with final practice, qualifying and the race yet to run.
"He came onto the grass and because of the rain, it was slippy. So that's why he flew off," said Marko on Perez's crash, as per Motorsport Magazin.
On the spares situation, Marko added: "We have enough spares, for both cars."
Asked to clarify whether that meant Perez was racing without spare parts, Marko confirmed: "No [he has none]."
This means Verstappen does have a set of spares left on his side of the garage.
