Just look at the overtake where Max got infront...

You can see the sheer increase in speed the RB gets when Max opens the DRS (the grid line just before HAM text in the chart title).
Then theres a 24kmh difference (DRS vs no DRS) when Lewis' car starts to recover....

Verstappen can then keep his foot in longer and by the time he lifts off to brake for the corner, theres a whopping 56kmh difference between them both.
Of course the speeds are much close using the following Lap (13), but it is a very interesting thing to see.
