Red Bull Racing has extended its engine naming partnership with Swiss watch maker TAG Heuer until the end of the 2018 Formula 1 season.
The team struggled to secure an engine for the 2016 season, having looked around for another supplier but without any luck.
Red Bull eventually opted to stay with Renault’s power unit for the current F1 campaign but brand them TAG Heuer.
The deal between the two has now been increased by a further two seasons to the end of 2018.
“I am very pleased to be extending our engine partnership with TAG Heuer today,” said Red Bull boss Christian Horner.
“TAG Heuer and Red Bull Racing are two brands which both have a passion for racing and a drive to do things differently, and this forms the basis of our partnership.
“The TAG Heuer motto of ‘Don’t Crack Under Pressure’ is something that we at Red Bull Racing live by day-to-day, so we look forward to helping TAG Heuer tell that story in the seasons ahead.”
