The Red Bull RB11 is a Formula 1 racing car designed by Adrian Newey for Infiniti Red Bull Racing to compete in the 2015 Formula 1 season. It was driven by Daniel Ricciardo and Daniil Kvyat. This was the last Red Bull car with engines originally badged as "Renault" and to feature their title sponsor Infiniti as they split from Red Bull at the end of the season due to a breakdown in the team's relationship with Renault.

After good results in previous seasons, 2015 was not a successful season for Red Bull. This was mainly due to the Renault engine lacking performance and reliability, compared to the Mercedes and Ferrari power units. They were unable to compete with Mercedes as they did in 2014, and also lost out to Ferrari and Williams, finishing fourth overall in the Constructors' Championship. The team suffered their first winless season since 2008 and their last to date, with the best results being 2nd for Kvyat in Hungary and Ricciardo in Singapore.

This genuine Nomex jacket/pants combo was used by a senior pit crew member throughout the 2015 season. This particular 2-part suit was traced back to Steve Forty, a Senior Garage Technician for RBR over the years. Forty is pictured wearing this very jacket in the below banner.
