Max Mosley: "There is always somebody new. If it wasn't him, it would be either [Nico] Rosberg or [Robert] Kubica or one of the other new stars, a [Sebastian] Vettel, would suddenly be the big one. So I think there is a tendency to exaggerate the importance of Lewis Hamilton."
Bernie Ecclestone: "He has been a real breath of fresh air and has resurrected F1. I have been in motor racing longer than I care to remember, but I have never seen anyone like him. He has been nothing short of a miracle worker. We lost a big hero in Michael Schumacher, but in Lewis we have another. But for him I'm not sure where the sport would be heading."
Stirling Moss: "He is a very impressive young man, the most impressive young driver I've seen in a long while...I have been connected with motor racing for 60 years now and he is certainly the best breath of fresh air we've had."
Mario Andretti: "He's a rare, rare talent. A rookie like this comes around once in a generation. You just try to step back and appreciate it."
Emerson Fittipaldi: "He's in a zone of calm and comfort like a veteran of ten years; his personality, the way he approaches the sport. I'm very impressed."
Frank Williams: "I thought after we got rid of Michael [Schumacher], 'Now we've got a chance again.' But then another superhuman turns up. Michael was many things, but he was also a very, very simple human. Hamilton is a different character I think, but purely in terms of calibre and quality of skill, what I'm seeing so early in this man's career is remarkable...I cry he's not in a Williams, but I rejoice for F1. I really do."
Jackie Stewart: "I think he is the brightest star to have entered F1 - ever!"
