. After three pre-season tests, one in
Jerez and two in
Barcelona, the RB8 arrived at the opening round of the
2012 Formula One season and its first race - the . Webber and Vettel qualified the car on the third row of the grid, setting the fifth and sixth fastest times respectively. During the race their pace improved in comparison to the other cars, allowing Vettel to finish second, and Webber fourth. At the following round, in
Malaysia, the cars had a similar qualifying performance to Australia, but wet weather prevented them from replicating the previous race result. Vettel, running in fourth place with a handful of laps to go, was involved in a collision which resulted in a puncture, placing him outside the points. Webber inherited the fourth place. The had a difficult qualifying in store for the RB8, in which Webber was seventh and Vettel ended up down in eleventh place. The two drivers gained places in the race though, with Webber overtaking Vettel on the final lap to take fourth place, leaving Vettel fifth. The
2012 Bahrain Grand Prix was the race at which the RB8 took its first pole position and victory, both courtesy of Vettel. He led all of the race, excluding the pit stop phases, despite pressure from the two
Lotus cars. Webber, after qualifying third, finished the race behind these two cars to take his fourth successive fourth place in as many races. The result of the race moved Vettel into the lead of the Drivers' Championship and Red Bull into the lead of the Constructors' Championship for the first time in the season. The was the first race after the only allowed in-season test at the
Mugello Circuit. The RB8 did not enjoy a weekend as successful as its last though, with Webber starting the race eleventh and Vettel seventh. Webber finished in the same place he started and Vettel gained one place to finish sixth after both drivers had to pit for the pit crew to replace the front wings on their cars due to a problem. Two weeks later at the , things were looking far better for the team, as Webber took pole position after
Michael Schumacher was penalised. Vettel, for the second race in succession, intentionally did not complete a full timed lap in the final part of qualifying, and started ninth. Webber eventually won the race to take the team's third successive win in the principality, while Vettel moved up to fourth and finished just 1.3 seconds behind the winner. Despite Webber becoming the sixth driver to win a race in the first six races, and the RB8 becoming the only car to win multiple races, it was becoming clearer who the team's rivals for the championship title would be. The
McLaren MP4-27, the
Ferrari F2012, the
Mercedes F1 W03 and the
Lotus E20 joined the RB8 near the top of the Constructors' Championship, and looked likely to make a bid for the title; other cars like the
Williams FW34 and the
Sauber C31 had produced good results, but looked unlikely to make a title challenge. Also, as a consequence of the race, Vettel lost his lead in the Drivers' championship. finished the in seventh position. After the FIA had deemed a hole in the floor of the RB8 illegal, the team had arrived at the with a slightly altered car. Vettel qualified on pole position, and after a close fight with Hamilton and Alonso for the majority of the race, finished fourth after making an extra stop due to poor tyre degradation. Webber encountered similar problems and dropped to seventh after starting fourth. Hamilton became the seventh winner in seven races and took over the lead in the drivers' standings as a result. At the following race, the , Vettel qualified in pole position for the third time in 2012, three tenths faster than Hamilton. Webber qualified in a lowly nineteenth position, but fought back during the race to finish an impressive fourth; Vettel retired from the lead on lap 33, with an alternator failure which would become a recurring issue for Renault engines and particularly the RB8, having led the whole race up to that point. At the , Webber qualified in second and Vettel was fourth at a wet Silverstone, where new championship leader Alonso took his first pole position of the season. Webber overtook Alonso for the lead of the race with a handful of laps remaining and Vettel finished in third place after losing ground at the start and making it back up to finish 5 seconds behind Webber. The at the
Hockenheimring was won by Alonso from pole position. Vettel and Webber qualified well behind him in second and third respectively, but Webber dropped down to eighth throughout the race. Vettel was running in third place in the closing moments of the race when he made a controversial manoeuvre around the outside of Jenson Button to take second place, where he appeared on the podium. After the race, however, Vettel was issued a penalty which dropped him to fifth because his car was completely off the track during the overtake. The
2012 Hungarian Grand Prix was the eleventh and last round of the season before the Summer break. Hamilton qualified in pole position and won the race, whilst Vettel started third, but finished fourth and Webber started eleventh and finished eighth. This left Webber and Vettel second and third in the Drivers' Championship, only two points apart but forty adrift of Alonso. Hamilton and Räikkönen also remained title contenders with Button slipping further behind. Red Bull led the Constructors' Championship and were firm favourites holding a 53-point lead over McLaren. Lotus and Ferrari were also contenders as both were within 3 points of McLaren; Mercedes's poor mid season had left them trailing. Over one month later, Formula One returned to Spa-Francorchamps for the . Vettel missed out on Q3 and qualified in eleventh for the second time in 2012, whilst Webber did slightly better to take eighth. Starting tenth on the grid, Vettel moved up to second during the race helped by a large collision at the start. Webber finished sixth as polesitter Button took the race victory, showing an improved McLaren pace. This improved pace in the RB8's main rival continued at the as Hamilton took the McLaren MP4-27 to its third successive victory. After Vettel and Webber took sixth and eleventh respectively during qualifying, the team suffered their first double retirement since the
2010 Korean Grand Prix. Vettel suffered another alternator failure and Webber spun violently at the Ascari chicane, with the resultant damage to his tyres sending vibrations through the car that forced him to retire. ; Webber was pushed off track by
Romain Grosjean on the first lap before he recovered to ninth place. Red Bull arrived in
Singapore with a new "double-
DRS" device fitted on the car. The system had been used by Mercedes near the start of the season, causing a stir due to an effect it created similar to that of the
F-duct system, banned after season. The teams unanimously agreed to ban its use for the 2013 season after the , but despite this Lotus made a version which they attempted to use before Red Bull. McLaren still looked to have a strong car with Hamilton in pole. Vettel and Webber qualified third and seventh respectively, and after Hamilton's gearbox failed when he was leading the race, Vettel inherited the victory. Webber finished in eleventh after taking a time penalty and losing the tenth place slot he initially finished in. The RB8, like the previous three of its predecessors, seemed very well suited the
Suzuka Circuit at the . Vettel took pole position and Webber qualified second to take the team's first row lock-out of the season. Vettel led every lap of the race, and set the fastest lap, to become the first driver to take successive wins in the 2012 season. Webber lost one place at the first corner and then was spun by
Romain Grosjean meaning he had to fight his way through the grid to finish ninth. As a consequence of Alonso's retirement at the start, Vettel narrowed the gap between himself and the Ferrari driver from 29 to just 4 points in the drivers' standings with 5 races remaining. Webber remained just in contention behind Räikkönen and Hamilton. Red Bull remained a healthy lead in the Constructors' standings over McLaren and Ferrari. At the , the Red Bull cars once again achieved a front row lock-out, except the cars were reversed with Webber in pole position. Vettel took the lead at the first corner, though, and took the victory and a 6-point championship lead whilst Webber completed a 1–2. Vettel's main rival for the title, Alonso, finished third in a Ferrari with improved pace, but was still at a disadvantage in terms of pace to Red Bull and McLaren. At the , Vettel took pole and Webber qualified second to take the team's third successive front row lock-out. It was the first time Red Bull had done this, and the first time anyone had since . Vettel led the race from start to finish, as he had done in Japan and Korea, and took his fourth consecutive win and his fifth of the season. Webber remained in second place for the majority of the race, but Alonso overtook him after he suffered a
KERS problem near the end of the race. Webber held off Hamilton in the final two laps to remain on the podium. == Sponsorship and livery ==
