Romain Grosjean and Esteban Gutierrez will drive for Haas in 2016, with the former being the first to sample the car when it hits the track on day one of testing.

Meanwhile Mercedes showed off the first images of the W07, following its shakedown at Silverstone on Friday and a whole host of teaser videos posted on Saturday.

The car features an updated livery, with more splashes of green and black, while executive director (technical) Paddy Lowe says there are "a lot of mini revolutions" under the car's bodywork.

The W07 will be driven by reigning world champion Lewis Hamilton and Nico Rosberg this season, their fourth year as team-mates at the Silver Arrows.
