Ferrari is the only leading F1 team not to introduce any car updates for the Singapore Grand Prix, with McLaren, Mercedes and Red Bull all submitting changes to their packages for the Marina Bay Street Circuit.
The FIA's car presentation submissions document for the Singapore weekend confirmed that just three of the 11 teams have declared updates, underlining a relatively quiet weekend for development as the championship enters its latest phase.
McLaren, Mercedes and Red Bull have each targeted specific areas of their cars, with cooling and aerodynamic performance among the priorities for the demanding street circuit.
Ferrari, meanwhile, has confirmed that it has no updates submitted for the event, leaving the Italian outfit as the only one of the four leading teams without a declared change.

McLaren, Mercedes and Red Bull introduce Singapore updates
McLaren has introduced a new front brake duct, designed specifically to meet the high cooling demands of Singapore and upcoming circuits.
According to the FIA document, the revised component aims to increase brake cooling mass flow, addressing a key requirement at a track where managing temperatures is particularly important.
Mercedes has submitted two aerodynamic changes, both focused on flow conditioning.
The first concerns the front wing, where the team has altered the chord distribution across its three elements and switched to a two-element small-flap configuration.
The team has also revised the front wing endplate and footplate to accommodate the changes, alongside adjustments to the diveplane camber.
Mercedes state that the revisions are intended to improve performance across the operating envelope, including better control of front tyre wake.
Red Bull has also declared two updates, covering both aerodynamic performance and cooling.
The first is a revised front wing, featuring modified endplate and flap geometries. The team say the changes are designed to deliver greater local load while maintaining flow stability.
Red Bull has additionally enlarged the rear wheel bodywork exit duct, modifying existing parts to increase cooling flow and accommodate the anticipated brake energy demands of the Singapore circuit.
