Unable to keep pace with world champions Mercedes and a resurgent Ferrari, drop to third in the standings, not helped by poor Renault reliability. Even so, Daniel Ricciardo and Max Verstappen prove their star quality by taking three wins between them.


The combination of superb RB12 chassis and much-improved Renault power unit (now badged TAG Heuer) sees the team bounce back to become Mercedes’ only serious rivals for race victories – and they take one apiece for Daniel Ricciardo and rising star Max Verstappen, who stuns by winning on debut after arriving from sister team Toro Rosso for round four onwards.


The superb turnaround of 2014 is swiftly forgotten as Red Bull are forced to deal with further power unit issues which contribute to them slipping down the competitive order – and falling out with Renault. Down on power compared to their rivals and suffering from patchy reliability, Daniel Ricciardo and new team mate Daniil Kvyat (who bested the Australian in the final reckoning) could only salvage three podium finishes and fourth in the standings – their worst such results since 2008.


After disastrous pre-season with uncompetitive Renault power unit, bounce back to finish second to all-conquering Mercedes, as only other team to win a race. Rising star Ricciardo takes three victories, dominating champion Vettel, who exits for Ferrari at end of year.


Renault-powered RB9 is once again quick out of the box, though the team complain that tyre degradation issues prevent them exploiting its full pace. However, the team surge ahead after the mid-season tyre change and wrap up their fourth consecutive constructors’ crown in India.


Ban on exhaust-blown diffusers robs RB8 of predecessor’s dominance, but continue to push technical boundaries, drawing controversy over floor holes, engine maps and more. Webber wins twice but it’s Vettel’s late season charge that rubber stamps third constructors’ title.


Vettel and RB7 all but untouchable throughout the season, scoring 11 wins and 15 poles in total. Webber takes three poles and one win at the final round. Rivals get closer, but not close enough, and team wrap up both titles with three rounds to spare.


RB6 normally fastest car, but reliability niggles, some unfavourable weather and odd driver errors mean team only move ahead in standings mid-season. Constantly improving car sees them ultimately take both titles, despite refusal to impose team orders on Webber & Vettel.


The quick RB5, and great drives by Vettel & Webber, propel Red Bull into the big time. Vettel scores their first pole and victory in China. Five more wins follow as team dominate latter part of season, finishing runner-up in both championships as Brawn’s only genuine rivals.


Despite a near identical chassis, the Renault-powered RB4 is increasingly overshadowed by its Ferrari-powered Toro Rosso sibling. David Coulthard’s third in Canada the team’s best result as they drop from fifth to seventh overall.


Tough start with Adrian Newey-penned RB3, recording at least one retirement in each of the first seven races. Mid-season updates improve pace and relieve reliability woes. Record best finish at European Grand Prix, with Mark Webber third and David Coulthard fifth.


Second season more difficult than first, despite Ferrari power. David Coulthard scores team’s first podium in Monaco, but overall amass 18 points less than in ’05 and face growing challenge from junior sister team, Toro Rosso.


Austrian-owned team’s first campaign, following 2004 purchase of Jaguar squad (formerly Stewart Grand Prix, 1997-1999), proves highly successful. Amass more points in the first two races than Jaguar managed the entire previous season. Go on to finish a clear seventh in the standings.
