McLaren looks to be the next team giving a sneak preview of its 2015 car.
Williams has revealed a rendered photo of its new car, the Mercedes-powered FW37, on the cover of the latest edition of British magazine F1 Racing.
McLaren's hint about the shape of its newly Honda-powered MP4-30, meanwhile, is much more subtle.
It is in the form of a video released by the team entitled "A new era begins", depicting a child sketching a white and red F1 car.
At the bottom of his sketch is a detailed outline of a modern F1 nose, in the style of the non-anteater shape of the title-winning Mercedes design.
In a release issued by former F1 team owner and boss Gian Carlo Minardi, the Italian referred to "rumours" of an "amazing and futuristic car" being prepared by McLaren-Honda for 2015.
"There is talk of a completely new chassis and a lot of innovation in many areas," Minardi said.
Team boss Eric Boullier, however, acknowledged that tracking down Mercedes' huge advantage in the first season will be a tough task for McLaren-Honda.
"I think it's going to be difficult to beat Mercedes," he told Britain's Sky, "but we will definitely try."
