Sauber are the first Formula 1 team to reveal their new car for 2017.
The C36 gives the first indications of how teams will approach the major rule changes introduced this year aimed at creating faster, more dramatic cars.
The Swiss team, who finished 10th of 11 teams last season, have introduced a new blue, white and gold livery along with the new-look machine.
These are the first pictures of a 2017 car following Williams releasing graphics of their model last Friday.
Sauber’s new technical director Jorg Zander says he expected “a clear improvement compared to last year”.
