Norris unsure about McLaren's Brazil upgrades

World champion Lando Norris said the McLaren upgrades to be used at this weekend's Sao Paulo Grand Prix were only aimed at increasing performance. Speaking in Mexico, Norris said he was not sure whether the upgrades would make the car easier to drive, and said they could even make his job harder.

McLaren have not been able to fight for race wins in recent races. Norris puts this down to the team being overtaken by Mercedes, Red Bull and Ferrari. The team is bringing a new front wing, rear wing and floor parts for Brazil. The aim is to regain the front while keeping third place in the Constructors' Championship.

Norris described driving the MCL40 as "terrible". He said, "The car was terrible all season and it was hard to drive. The other teams made far more upgrades and developed much more than we did." Norris won in Hungary and Zandvoort in succession, and should have won in Spain, but the virtual safety car prevented him from doing so.

Norris stressed that at the start of the season the team was one to 1.5 seconds behind its rivals, and that winning almost three races was a big achievement. Norris is currently sixth in the Drivers' Championship.
