Via a story post on his official Instagram account, Bottas shared a selfie of himself in his new Mercedes fire suit standing beside the new-look car.
The German manufacturer has teased fans with imagery of the W12 in the build-up to its reveal, sharing renders of the airbox and front wing, the two elements that sport INEOS and Petronas branding respectively.
Captioning his story, Bottas wrote simply: "A sneaky peak [sic] at this year's new look." The comment was accompanied by a knowing wink.
Mercedes has since also shared the post.
