McLaren’s upgrade is "a pleasant surprise" – but will it stay on the car in Brazil?

After one of the most turbulent world championship defences since Jenson Button in 2010, Lando Norris gave McLaren’s latest batch of car upgrades a cautious thumbs-up on the Friday of the Sao Paulo GP. Norris topped the first practice session, edging out Mercedes’ Kimi Antonelli by 0.082s, and was among the quickest in terms of average pace on his long runs through FP2.

"Certainly FP1 was a little bit of a surprise, a pleasant surprise," said Norris.
