As Lewis Hamilton became F1 champion for the second time with victory at the Abu Dhabi Grand Prix, Daniel ended his first season with the Team on a high, powering from the pit lane at the start to fourth place at the chequered flag.
Daniel thus finishes the campaign in third place in the Drivers' Championship standings with 238 points and as the only driver to beat title-winning Mercedes in a race this season.
Sebastian Vettel, meanwhile, ended his final season with the team with eigth place at Yas Marina, the circuit at which he took his first championship title with the team in 2010.
Finally congratulations to Lewis Hamilton on achieving his second world championship, he's a very deserving winner after the season he's put together and it's fitting that he won.
Overnight both Red Bull drivers were sent to the back of the grid after race stewards ruled that the team's front wing contravened regulations and the team later elected to start both Seb and Dan from the pit lane. When the lights went out at the start and the pair took to the track they made short work of making their way through the order as at the front Hamilton made a great getaway to lead pole sitter and title rival Nico Rosberg into the first corner.
Both Daniel and Seb started on the prime soft tyre and after passing slower cars and then rising through the order thanks to the pit stops of rivals who started on Pirelli's supersofts, Daniel found himself in fifth place after just 15 laps, with Seb eighth, though the outgoing champion's progress was being hampered by the McLaren of Kevin Magnussen ahead of him.
I'd like to thank Red Bull and the Team for everything they did and I will miss them.
On lap 21, complaining that his rear tyres were beginning to go off, Sebastian made his first pit stop, taking on new soft tyres for his second stint. Daniel stayed out on track, however, and he was the last man on track to change tyres, the Aussie eventually pitting on lap 27. He also took on new soft tyres and set about a long 20-lap stint on his second set. The supersoft-starting rivals ahead of him then began to make their second stops and Daniel then climbed to third. Having used two sets of soft tyres, however, he would need to pit again to take on a mandatory set of option tyres. He did that on lap 47, eight laps from home.
The stop dropped him behind Williams' Valtteri Bottas, who had taken on a set of used soft tyres 12 laps earlier. Daniel undoubtedly had pace in hand, but unfortunately there was also a 20-second gap to the Finn, which was just too much to make up in the closing stages and so the Australian finished fourth.
Daniel was pleased with the result, however, especially after being sent to the back of the grid by the stewards.
"Yeah really happy, I think it was pretty much a faultless race from all sides, from the strategy, to myself and the pit stops, everything was good so we did everything we needed to do," he said.
"I had fun passing, it wasn't boring out there, so it was pretty much what I asked for. One spot better would have been nice, but fourth is really cool from the pit lane," he added.
Summing up his first campaign with Infiniti Red Bull Racing, Daniel said that apart from not winning the title, the season had been "pretty much a perfect season".
"It's been as perfect as it can be without holding a world title, so no real regrets, no complaints," he said "It's nice to not only start the season well, but to finish it well also and I think all the way through it was good - we had a strong summer as well, so the start, middle and end were pretty good!"
Sebastian, meanwhile, also ran a long second stint, pitting for his set of option tyres a lap before Dan, on lap 46. The stop saw him rejoin in 10th place, behind Ferrari's Alonso. He quickly made his way past the Spaniard and set his sights on Nico Rosberg ahead. Rosberg's race had been dealt a blow at the start when Hamilton took the lead into the first corner but the German title contender had stayed in touch with the Englishman throughout the first stint.However, on lap 25 his car began to lose power. His team diagnosed an ERS failure and down on horsepower and battling braking and throttle problems his title challenge rapidly unravelled.
He steadily dropped back from second and in the closing stage he found himself eighth, with a hard-charging Sebastian closing quickly. He could offer no resistance and Seb swept past into his finishing position on lap 49.
"I felt there was more, but once I got stuck behind Kevin at the beginning it was quite tough, so I can't be completely happy with today; when you race you want to finish as high up as you can and today I think we had the pace to finish higher," said the four-time champion.
Ahead, Hamilton took his 11th win of the season and his second career title. Felipe Massa finished second, ahead of team-mate Valtteri Bottas. With Daniel fourth, fifth place went to McLaren's Jenson Button. The Force India's of Nico Hulkenberg and Sergio Perez were sixth and seventh respectively and with Sebastian eighth the final two points places went to Alonso and Ferrari team-mate Kimi Raikkonen.
Commenting on his six seasons with the team Sebastian said it had been "an incredible journey".
"Obviously we didn't expect that when we started working together – you can never expect four Driver titles and four Constructors' Championships in a row," he said. "You get to know some people in a very good way and build friendships that will last a long time. You go through happy days and sad days, you go through them together and I think I learned a lot. I'd like to thank Red Bull and the Team for everything they did and I will miss them. I feel ready for the next step."
Team Principal Christian Horner later paid tribute to the four-time champion's time with the team, while also hailing Daniel's drive as "phenomenal".
"[Daniel's drive was] an incredible recovery after the circumstances of Saturday, signing off a fantastic season for Daniel finishing third in the World Championship and an unbelievable year," he said.
"For Sebastian, P8 isn't reflective of his time within the team, four world championships, 38 grand prix victories, four Constructors' World Championships and 44 pole positions," he added.
"He's been a fantastic team member he's been an absolutely awesome competitor. He's been a pleasure and delight to work with and we wish him well for the future; he'll always be a friend of the team. Finally congratulations to Lewis Hamilton on achieving his second world championship, he's a very deserving winner after the season he's put together and it's fitting that he won."
