For only the second time in the 62 years of F1, this season has so far resulted in five different drivers and five different constructors winning the first five races.
Reigning champion Vettel, like many around him, does not dispute the point, but feels this year’s title winner will still prove to be the best driver-car combination.
Ahead of this weekend’s Monaco Grand Prix, Vettel said: “There’s a long way to go, but at the moment it’s difficult for us to understand why we’re sometimes quick, sometimes slow.
It’s probably harder for people on the outside to understand why their favourite driver wins one race and then at the next race is in the midfield or nowhere.
“Overall, if you look at the first five races, the drivers and teams at the front deserve to be there.
“We’ve had five different teams, five different drivers winning, but over 20 races it will not be right to say the winner of this year’s championship will be lucky.”
