FIA make major F1 change ahead of 2025 Singapore Grand Prix

The FIA has elected to raise the pit-lane speed limit for the
Singapore Grand Prix in an attempt to create more strategic
variance. Owing to the tight surroundings of the pit-lane at the
Marina Bay circuit, the usual 100kph limit is reduced to 60kph to
protect team members working in the pit-lane from being struck by a
car or by flying debris in case of a collision.  This means drivers
spend longer in the pit-lane, with teams therefore reluctant to
lose race time and track position with multiple stops at a circuit
which is also tough to overtake on.  The race has morphed into a
one-stop when dry, but in a bid to combat this, the minimum
pit-lane speed limit is to climb to 80kph (49.7mph) from the 60kph
(37.2 mph) limit in force in previous years. Raising the pit-lane
speed limit was one factor discussed by F1 bosses in an attempt to
enliven races strategically, following an increased number of
one-stop grands prix, devoid of any major variance. Pirelli has
brought the C3-C4-C5 tyres to serve as the hard-medium-softs, with
the new softest tyre in the range, the C6 not being used as it was
last time out during the Azerbaijan GP, another street circuit.
