Lewis Hamilton says a suspension problem ahead of the Sprint race was the catalyst for a “terrible” day as he dropped out in Q1 at the United States Grand Prix.

Mercedes looked quick throughout the Sprint Shootout on Friday evening but a yellow flag on Hamilton’s final lap prevented him from having a chance of setting the fastest time. A largely uncompetitive run to sixth place in the Sprint was put down to a suspension issue, but Hamilton believes there was an issue with the car’s configuration after that as he finished 19th in qualifying.
