The full list of upgrades Formula 1 teams are bringing to the Singapore Grand Prix is out.
Mark Hughes summarises what’s new at Marina Bay, including changes at Red Bull and big pushes from the teams fighting for fourth in F1’s constructors’ championship.
Red Bull
A subtle reprofiling of the floor fences is all that Red Bull is reporting.
This team’s intricate matching of fences and floor details with circuit requirements has been notable for much of the season.
McLaren
Although the reprofiled radiator inlets are the most visually obvious of the changes McLaren has brought here, they also include accompanying changes to the fences and forward floor body.
The demands of the circuit mean extra bodywork and front brake cooling too.
There is a revised diffuser which may be tried during FP1.
Alpine
Alpine has brought a very significantly different new floor, the effectiveness of which the team is very bullish about.
It reports improved vortex control from the underfloor and floor edges as well as better controlled tyre squirt ahead of the rear wheels.
AlphaTauri
A new front wing is quite rare occurrence in the cost-controlled era but that’s what AlphaTauri has brought, to increase load on the inboard part and changes to the outboard part to improve wheel wake control.
Aston Martin
Aston Martin has introduced different detail to its floor edge for more effective vortex generation.
Williams
Williams has changed the material of the rear brake duct for better reliability.
Mercedes, Ferrari, Haas: No updates reported.
