Jenson Button believes Mercedes could still triumph in the new era of high downforce thanks to the superior power of their engine.
Mercedes have dominated Formula 1 since 2014 when the sport introduced 1.6 litre V6 hybrid engines for the 2014 season.
Since then the team has claimed 51 race wins, three Drivers’ titles and all three Constructors’ Championships.
Rivals, though, are hoping that this season the gap to Mercedes will be reduced if not overhauled as the sport welcomes a new era of wide wings and tyres, and increased downforce.
Button, however, concedes that Mercedes’ engine power may negate that.
