Former F1 driver Sir Jackie Stewart called it ‘difficult to justify’ saying Lewis Hamilton is the greatest ever driver.
He has already overtaken the German’s record of 91 race wins.
But Stewart, who won the driver’s championship three times, described it as near-impossible to compare Hamilton’s achievements to speedsters of yesteryear.
The 82-year-old said last year that the modern-day racing calendar being busier, as well as Hamilton having a ‘so superior’ car and engine to other competitors, makes comparison tricky.
“Just because today there are 20, 22 races, whereas in the old days when for example Juan Manuel Fangio, raced maybe sometimes six, eight or nine races a year in Formula 1.
‘To say that Lewis is the greatest driver of all time, would be difficult for me to justify, in the sheer power of what the other drivers were doing.
“Lewis drives extremely well, make no mistake, I’m not in any way diminishing his skills, but it isn’t the same.
“Lewis made a very good decision when he left McLaren at that time and went to Mercedes-Benz. And I take my hat off to him for making that decision.
“But frankly, the car and the engine are now so superior that it’s almost unfair on the rest of the field.”
Due to difficulties comparing the modern-day car and calendar with that of the past, Stewart doesn’t even have Hamilton in his top three racing drivers of all time.
He added: “Juan Manuel Fangio in my mind is the greatest driver that’s ever lived.
“With Jim Clark as the second-greatest, even ahead of [Ayrton] Senna.”
