Red Bull have extended their engine branding partnership with TAG Heuer for another two seasons.
The new contract, announced ahead of the Abu Dhabi GP, aligns with the team's deal for Renault power, which also lasts until 2018.

"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," said Red Bull boss Christian Horner.
After winning four consecutive world championship doubles between 2010 and 2013, the Red Bull-Renault relationship turned increasingly sour with both sides criticising each other in public for their early struggles in F1's new V6 hybrid era.
Red Bull were rebuffed by Mercedes, Ferrari and Honda's partner McLaren in their attempts to source an alternative supplier for 2016, before an 11th-hour deal was eventually struck for the team to continue running Renaults, although under the name of new sponsor Tag Heuer.
As part of the extended deal, both Red Bull and Toro Rosso 'have the opportunity to badge the power units as they wish' in 2017 and 2018.
