#3 Mercedes
After a few years of a very standard silver livery, Mercedes have chosen to change things up a little and did so with some cheek and a whole lot of success. After teasing some possible crazy combinations of blue and black on the car (which ultimately ended up being the wheel rim pattern,) Mercedes introduced a sleek silver and black update to their 2019 title challenger.
They have also added a checkering of Mercedes stars on the bodywork of the 2019 car which fades into view on the darker parts of the chassis. A lot of graphic designers release hypothetical liveries for many F1 teams, and I think for once Mercedes may have outdone all of them, with a completely unique flash on their 2019 title challenger.
The modern design of this all-new car just makes it even more apparent that Mercedes are on the eight-ball and are not keen to stay behind the wheel in any aspect of the sport. This car looks like it could be a championship contender any day of the week and that's a testament to how sleek the livery is.
