Ferrari: The most reliable engine constructor of the year

#2 Turbo Charger

Nico Hulkenberg had to face turbo reliability issues throughout the year

Turbo: Mercedes = 19, Ferrari = 18, Renault = 28, Honda = 16

Red Bull were severely affected by the tightly packed engine to suit their aerodynamics and used 10 turbo chargers, 6 for Daniel Ricciardo's car and 4 for Verstappen's. Renault used up the same number - 6 for Hulkenberg and 4 for Sainz.

Alonso and Vandoorne used 4 each to make a total of 28 turbo chargers. The turbo chargers of the Renault engines had a tough time in each of the three teams running them, unlike those of the Ferrari run cars who stuck to their limit of 18.

Ferrari ended up with the most reliable turbo charger this year. Bottas was the sole driver to use an extra turbo for his Mercedes. As for Honda, Gasly and Hartley went through 8 turbos each, incurring more grid penalties as they ran tests after tests to catch up with the rest of the field.
