No Hamilton issue
Mercedes has dismissed worries about the state of Lewis Hamilton’s Formula 1 engine, despite the world championship leader expressing concerns about a vibration after winning the Japanese Grand Prix. Hamilton came on the radio following the chequered flag to say that he had experienced a vibration with his power unit in the latter stages and had been short shifting. On a weekend when title rival Ferrari suffered more engine reliability problems, Hamilton’s issue prompted suggestions that Mercedes could have hit trouble too. But speaking after the race, Mercedes motorsport boss Toto Wolff said the telemetry indicated there was no problem.
