Several components on the MCL35 were re-designed to account for the high-load nature of the Turkish Grand Prix. Sainz suffered an issue with his power unit's electronics in the first practice session, triggering a virtual safety car and causing him to miss most of the session. Norris and Sainz originally qualified eleventh and thirteenth respectively. However, Norris was given a five-place grid penalty for breaching yellow flag conditions, with stewards saying "Car 4 was not attempting to set a quick lap time, due to the changing track conditions he nevertheless did so and thereby breached the referenced regulations." Sainz was given a three-place grid penalty for impeding Pérez, which Sainz said was partially due to the weather conditions. Sainz recovered to fifth and Norris recovered to eighth while the latter also set the fastest lap of the race. Sainz overtook Norris for seventh in the Drivers' Championship. The result meant that they exceeded their 2019 total of 145 Constructors' Championship points over 21 races, having scored 149 points in fourteen races.
