RED BULL have faced ‘big hurdles’ in preparing the car Max Verstappen will use in his Formula One title defence.
Team advisor Helmut Marko told Austrian publication Kleine Zeitung the sport’s new financial restrictions and sweeping technical changes have proved challenging.
Marko also said the intense season-long battle against Mercedes and their main man Lewis Hamilton for the the Drivers’ and Constructors’ 2021 titles had been tough to juggle alongside car development.
He explained: “We faced two or three big hurdles.
“It was the biggest change in regulations in the last 15 or 20 years.
“All the new designs and planning had to be done within the budget cap.
“And then we were fighting for a World Championship and had to move the new car forward at the same time.”
Red Bull recently unveiled its all-new F1 car – the RB18 – for the 2022 season.

Marko said that unveiling was important in terms of sponsors, but that there is plenty of work still to be done on the RB18 before the new campaign gets underway in Bahrain next month.
He added: “That was a presentation for the time being, it’s especially important for our partners.
“The first roll-out will take place later. And until the first race in Bahrain, there will be some changes.
“We don’t reveal everything at the presentation, there are still some updates to come.”
