Mercedes driver Lewis Hamilton has said that he cannot recall a season when he has been so consistent.
The 29-year-old has won the last two races in Singapore and Italy as he continues to extend his lead over teammate Nico Rosberg at the top of the drivers' championship.
Hamilton's recent form has led him to suggest that it has been his best season since making his F1 debut in 2007.
"This has been the most consistent, best-performing season I remember having," Hamilton told BBC Sport. "I want to continue that for many years."
Hamilton has also said that he is "optimistic" ahead of this weekend's Japanese Grand Prix, where he could edge further ahead at the top of the individual rankings with another victory.
"I have come here just as excited and optimistic as I was before Singapore," he added.
"I have never come to Suzuka, which is one of the best tracks, with a dominant car and I know I have a chance for pole and a chance to win the race. It is a great feeling."
There have been suggestions that the Japanese Grand Prix could be cancelled due to reports of a typhoon hitting the country.
