Lando Norris has offered a cautiously positive assessment of McLaren's upgrade package introduced for this weekend's São Paulo Grand Prix.

McLaren is the only team to have brought updates to Interlagos, fitting a revised floor, a new beam wing, a reworked rear wing and a test-concept front wing, aimed at generating downforce more efficiently without adding excessive drag.
