MONTMELO, Spain -- Lewis Hamilton may be a four-time world champion, but he is still keen to prove he is the best driver in Formula One on a level playing field.
Hamilton returned to action in pre-season testing this week, setting the fastest time of the test on Thursday afternoon in his new Mercedes W09. His team is expected to continue its four-year reign at the top of the sport this season but is facing increasing competition from rivals Ferrari and Red Bull after both closed the gap in performance to Mercedes last year.
But rather than see a return to the domination Mercedes enjoyed between 2014 and 2016, Hamilton hopes there is nothing to choose between the top teams this year.
