Red Bull Team Principal Christian Horner has said that he does not think the RB18 is 'particularly fragile'.

The RB18 is certainly one of the fastest cars on the grid at this stage of Formula 1's new era but it has also given the team a few headaches along the way over the first five rounds.

Indeed, they had a double retirement at the first race of the season in Bahrain and Max Verstappen had a further issue in Australia, which cost him more points.

When they finish, though, they finish well and that can certainly be said for the Dutchman who has won every event that he has reached the chequered flag in so far in 2022.

Naturally, though, with their start in mind and Sergio Perez having to manage an issue at the weekend at the Miami Grand Prix, there are still questions being asked about the reliability of the car.

Horner, however, has played down the idea that it might be a little less robust than some of its competitors, and he has backed the team and HRC to make the car extra bulletproof for the races ahead.

"I don't think the car is particularly fragile," Horner said post-Miami.

"I think there have been niggly things that you would normally have seen in pre-season testing that have only reared their head as we have got into the season so that has been frustrating.

"We are working closely with HRC and they are giving us great support so I think we will get those ironed out."
