Nine of the 10 teams have brought at least one new component to the Las Vegas Grand Prix as Formula 1 enters its final run of races of the season.
Las Vegas kicks off a tripleheader that will also encompass Qatar and the season finale in Abu Dhabi, and so there are limited developments spread across the grid. Only Williams doesn’t have any new parts listed, having faced a race against time to repair heavily damaged components in the two weeks since Brazil.
At Red Bull there is a new front wing and floor fences, with the latter upgrade improving floor performance further downstream. McLaren and Mercedes both also have updated front wings that are described as circuit-specific, as does Ferrari where there is a much bigger change to the floor.
Evolutions of the floor fences are delivered in conjunction with a reshaped floor body and floor edge, with Ferrari saying the fences change is “targeting an improvement of the losses traveling downstream. The front floor body volume has subsequently re-optimized, together with the floor edge loading and vortex shedding into the diffuser.”
Aston Martin follows the trend of a circuit-specific front wing, while Alpine has developed its front corner to provide a new brake drum profile and improved build quality overall.
RB has a number of new components, with bodywork changes on the engine cover seeing the ramp down behind the sidepods being lowered, while rear suspension modifications are paired with updated rear corner winglets. There’s also a modification to the mirror housing for drag purposes.
Stake has also brought a brand-new floor and diffuser to Las Vegas, completely changing the main body of the floor.
“The updated floor in its entirety aims to improve the flow characteristics under the floor by rearranging vortices and maintaining losses under control,” the team says.
At Haas, the rear floor expansion shape has been modified, designed to improve performance when the car is at lower ride heights.
