Despite App-hack, Williams gives us peak at 2021 FW43

Williams Racing planned to reveal its 2021 challenger, the FW43B, via an augmented reality app later today (March 5th).

However, sadly, because the app was hacked prior to launch, this will no longer be possible.


Williams Racing today (March 5th) proudly launches its 2021 Formula One challenger, the Williams Mercedes FW43B, featuring a striking new livery for the season ahead. The team’s new look captures the spirit of the team’s past, the present transformation and its drive to future ambitions as it heads into its first full season of ownership under US based Investment company, Dorilton Capital.

Whilst evolutionary on the technical side due to the regulations, hence the designation FW43B as opposed to the FW44, the 2021 car will race with a dramatic new visual identity sporting a livery inspired by Williams’ all-conquering cars of the 1980s and 1990s, combining blues, white and yellow accents.

Speaking for the first time as CEO of Williams Racing, Jost Capito said: “Williams Racing is a sporting icon, and a team that has forged a reputation of success through sheer determination and grit intertwined with innovation, passionate and skillful race-craft and an absolute desire to win. Highs and lows are typical in any long-established sporting brand’s journey and historic success can be a strong motivator, but it cannot be relied upon to define future success in the modern era of Formula One.

“Therefore, we have created a fresh new livery for the 2021 car; one that acknowledges our incredible past and retains the spirit, drive and motivation that remains at the core of Williams’ DNA yet looks to the future and signposts our long-term ambition to return to the front of the grid. Whilst we are just starting out on this journey and there is still a lot of work to do, we are happy to see momentum in the right direction and look forward to continuing that progress on track this season.”
