Formula One: Mercedes' lack of pace, a concern for Lewis Hamilton in Japan
F1 leader Lewis Hamilton heads into this weekend's Japanese GP grateful to have extended his overall championship advantage, but conscious that his Mercedes team have their work cut out to rediscover their car's lost speed. The German team were the third slowest team for the second weekend in a row at the last race in Malaysia, after also similarly struggling for pace in Singapore.
The Briton heads into Sunday's race at the Suzuka circuit, where he has won twice before, with a heftier 34-point lead over the Ferrari driver with five races to go, but only because of the misfortune that has blunted the German's championship charge.
