This helps to understand a bit more. The speed trap numbers are illuminating.
The engine modes are not exactly unknown if you have followed these numbers. There are at least 3 to 4 engine modes (combination of ICE + Battery deployment) for long runs that almost all teams use.
One is around 275-280kph.
Second one is around 280-290 kph.
Another one at around 290-300kph range, depending on fuel loads.
These may vary a little depending on how many straights a circuit has (energy deployment) or how long the straight is. These modes are used in testing and Free practices.
The last one is usually the actual race mode, which is anywhere between 300-310kph. It is this mode which is also used for quali with the exception that they dump the whole battery for one lap. Add DRS to it, you would see 320-330+ kph.
In practice, when they go on softer compound, they lower the engine mode and as they move towards harder compound, they increase the engine mode a bit to offset the performance loss between the two compounds.
