Lewis Hamilton says he has not considered the prospect of retiring from Formula One before the current engine regulation cycle expires in 2020.
Hamilton, who has won three of the last four championships with Mercedes, enters the final year of his current deal in 2018. The Englishman moved clear of Michael Schumacher's record for pole positions in 2017 but has said he has made it clear he has no ambition to actively chase or beat the German's tally of seven titles.
Despite that, he sees no reason to quit F1 while he is still enjoying his racing.
