Hadjar says Red Bull need better starts and radio ahead of Mexico

Isack Hadjar says Red Bull need to improve their starts and radio quality ahead of the Mexico City Grand Prix. He said the radio issue makes it difficult to race, but described the team's raw pace as very strong.

A slow getaway hindered Red Bull at the United States Grand Prix. Hadjar matched his best-ever qualifying result with third place in Austin, then dropped down the order on the opening lap. He suffered a throttle problem before finishing sixth.

Hadjar said Red Bull had managed good starts in the past. At other times, he said, the team thought the weakness was under control before it went the other way again; Austin was one such weekend. He could not guarantee anything, and said nothing could be done in the final couple of days before Mexico, so Red Bull would go with what it had.

He called Mexico a very different challenge, describing the track as slippery and saying drivers slide around there. The long run to Turn 1 could, he said, provide a helpful tow.
