Montreal - Formula One needs more diversity and drivers need to toughen up if the sport is to become more entertaining and grow, five-times world champion Lewis Hamilton said on Thursday.
Years of tweaking the rules and attempts to control costs have only marginally improved the product, the Briton told a news conference ahead of Sunday's Canadian Grand Prix.
Acknowledging that Formula One is often seen as "boring" and often dominated by a single team, like his own Mercedes who have won all six races this season, Hamilton mused on a return to V12 naturally-aspirated engines, manual gearboxes and the removal of steering assistance to put the focus back on drivers.
Stopping short of labelling drivers as wimps, Hamilton made it clear that driving Formula One is no longer the physical test it should be.
"People do continue to comment that it’s boring," Hamilton said. "How you stop that, that is definitely a part of the regulations but I think on a more global scale, I think there needs to be some more changes outside of the regulations in my opinion.
