Mercedes has been crowned Formula 1 constructors’ champion for the fourth consecutive season after moving into an unassailable lead in Sunday’s United States Grand Prix.

Lewis Hamilton stormed to his ninth win of the season in Austin on Sunday after perfecting a one-stop strategy to finish over 10 seconds clear of Ferrari rival Sebastian Vettel.

With teammate Valtteri Bottas taking P5, Mercedes extended its lead over Ferrari by a further two points at the Circuit of The Americas and clinch the constructors’ title in style.

After winning its first constructors’ title with its works team in 2014, Mercedes followed it up with further successes over the last two years ahead of the overhaul of the technical regulations for this season.

Despite the changes allowing Ferrari to gain ground and put up a closer fight at the front of the field, Mercedes has led the constructors’ since the Canadian Grand Prix in June, with its lead growing rapidly in recent races.

Mercedes arrived in Austin 145 points clear of Ferrari, needing to be just 129 ahead after the race to clinch a fourth straight crown.

Mercedes has become just the fourth team in history to win four constructors’ titles in a row, following Ferrari, Red Bull and McLaren. It also marks its sixth teams’ trophy as an engine supplier, with Brawn and McLaren’s titles in 2009 and 1998 joining its in-house successes.
