Red Bull’s chief technical officer Adrian Newey admits the mid-season change in tire construction by Pirelli aided their cause but was not a “magic bullet” which transformed their car.
Pirelli revised their tires on safety grounds following the British Grand Prix where several drivers suffered high-speed explosions.
“Going back to 2012 tires, for sure, helped us,” Newey told Reuters. “The 2013 tires were much more load sensitive. It was much more easy to damage them if you put too much load into them.”
Newey also believes more of the circuits in the second half of the season suited the RB9 chassis. The series of Asian races following the summer break has traditionally been a strong phase of the season for Red Bull, who have won 11 of the last 12 races in Singapore, Korea, Japan and India over the past three years.
He added there were some concerns in the team that Mercedes were going to overtake them in terms of pure performance. Their rivals took pole position in eight of the first eleven races of the season.
Newey’s focus has now turned to the coming overhaul of the engine rules: “Next year we have this big regulation change which is exciting and nerve-racking at the same time,” he said. “So that’s my immediate concentration. After that we’ll have to see.”
