Despite their three Championship doubles, Red Bull team boss Christian Horner insists his outfit has lost none of their motivation to succeed.
Red Bull has been the team to beat in recent years, claiming three Constructors' titles on the trot. However, added to that the team has also dominated the Drivers' standings with Sebastian Vettel becoming a three-time Champion last season.
It has been an extremely successful run for the Bulls with Horner highlighting their "desire and determination" as key factors.
"This is our ninth year in Formula One," he told Press Association Sport.
"That desire and determination within the team has been one of our strengths over the years.
"Even if we've won a race we've looked inwardly and said 'Where can we improve?' and 'Where can we continue to develop?'
"There is this real philosophy throughout the organisation that showed up over the winter,
"Last year, given the title race went down to the wire in Brazil, it meant we were developing all the way through.
"The knock-on effect was that the amount of design and production time we had for this year's was the shortest for all the cars we've produced so far.
"Yet the car hit the first test on time, was reliable and looked reasonably quick out of the box.
"The way the team is working as a group, and with the stability we have had across all areas, that is hugely important to us."
But while the 'desire and determination' are still strong, so too is the pressure especially that from within to continue Red Bull's run of titles.
"Any pressure is what we put ourselves under," Horner said.
"Having won three double World Championships is something fantastic and something every member of the team is extremely proud of.
"They're in the history books now. Nobody can take them away from us, and we've shown we're not a flash in the pan as people thought of us after our first double Championship.
"So in many respects the pressure is off, but in others we want to maintain the roll we have been on over the past few years.
"There is a real determination within the team to keep this run of success going, to do our very best to defend both of those titles this year."
