Monaco has the greatest undulations relative to any circuit on the calendar meaning a soft car is required; allowing the tyres to retain contact with the tarmac as much as possible. This means softer roll bars and springs; the aim being to maximise mechanical grip without losing too much aerodynamic grip.
Brakes are not a big concern. The low speed layout means drivers are not braking as significantly as they would from a long straight into a first gear corner, and it's also a shorter race than most so wear is not an issue. Monitoring temperatures is essential as there aren't any real high speed sections to cool the brakes, and the relentless stop / start nature can compound heat generation. The brake calipers tend to run hotter in Monaco than any other track, so more attention is paid to them than normal.
This race will see Pirelli's red marked supersoft tyre appear for just the second time this season – Australia being the first – alongside the soft compound. Tyre wear is very low here due to the smooth track surface and low speed layout.
An engine with very good response is essential, with drivability rather than ultimate power being the goal. You'll never go slower with more power, but it's the least power sensitive circuit of the year. The engine spends a relatively short amount of time at full throttle so the challenge is to deliver torque through the lower rev limits of the engine. With Monaco being such a bumpy street track, the engine also needs a good limiter setting so it is capable of digesting all the bumps. Finally, fuel consumption needs to be calculated very accurately, as the track gets quicker and quicker over the weekend.
